JavaScript project with purpose to propose an fast and lite autocomplete. And there is without dependency.
Very lite.
< {{ page.autocompletejs.size }}KB
Only Native JavaScript Function
Great !
No data pre-loaded.
Only easy AJAX.
//Simple declaration with default parameters
AutoComplete();
//Call with custom parameters
AutoComplete({
paramName: "query",
method: "POST",
noResult: "No item like this",
});
<!--HTML declaration -->
<input type="text"
data-autocomplete="http://…"
data-autocomplete-method="POST"
data-autocomplete-type="HTML"
data-autocomplete-param-name="query2"
data-autocomplete-no-result="Regex no matched"
data-autocomplete-limit="10" />
<!-- data-autocomplete (url) is required
data-autocomplete-method (GET|POST|PUT|DELETE or all others method) is optional
data-autocomplete-type (JSON|HTML) is optional
data-autocomplete-param-name is optional
data-autocomplete-no-result is optional
data-autocomplete-limit is optional
-->
It's the main argument. Without it, no autocomplete possible. This argument is string type and is indicate only in HTML. Unlike other autocomplete, autocomplete.js doesn't take argument in JavaScript. This information is exclusively in the input attribute "data-autocomplete". It's for this reason that the selector default value is input[data-autocomplete].
<!-- HTML declaration -->
<input type="text" data-autocomplete="http://…">
limit is a argument added to 1.4 version. It give the possibility to add two conditions easily. The default value is 0.
This is the two features.
//Show all results
AutoComplete({limit: 0});
//Show the 5 firsts results
AutoComplete({limit: 5});
//Show the 10 lasts results
AutoComplete({limit: -10});
<!-- HTML declaration -->
<input type="text"
data-autocomplete="http://…"
data-autocomplete-limit="5" />
selector is array type. This option is a primary information because these are the data which identify inputs to select.
The default array is :
//Default selector
{
selector: [
"input[data-autocomplete]"
//input[data-autocomplete] must to select all inputs with one URL.
]
}
//If you use many ID selector
{
selector: [
"#myFirstIDSelector",
"#mySecondIDSelector",
...
]
}
The rules to select an input text type are the same that CSS (#id, .class, tag, [attr], …). You can read the MDN Documentation for most information.
method is string type. This option is available since the v1.0. The default value is GET.
This option define the method to send the XMLHttpRequest. All methods are defined in the RFC2616 which explain the HTTP1.1 protocol.
This option is a string and the parameter isn't sensible case.
There are two possibilities to set a custom value.
Before 1.6 version (1.0 to 1.5), this parameter took only two values (GET and POST). Since, , the method use it depends developper fully. No check applies, only XMLHttpRequest must throw an exception.
//Send GET request with default value
AutoComplete();
//Send GET request in define value
AutoComplete({method: "GET"});
//Send a POST request
AutoComplete({method: "POST"});
//Send a PUT request
AutoComplete({method: "PUT"});
//Send a DELETE request
AutoComplete({method: "DELETE"});
<!-- HTML declaration for a POST request -->
<input type="text"
data-autocomplete="http://…"
data-autocomplete-method="POST" />
headers is object type only declarable in javascript. This option is available since the v1.7. The default value is {"Content-Type": "application/x-www-form-urlencoded"}.
//Send request with specific headers
AutoComplete({
headers: {
'apikey': "myApiKey",
"secretKey": "mySecretKey"
}
});
paramName is string type. This option is available since the v1.0. The default value is q.
It allows define the parameter name which contains the value when the request is send.
This option is settable with two attributes, DOM and/or JavaScript.
//How custom the parameter name to send request
AutoComplete({paramName: "query_to_search"});
<!-- HTML declaration -->
<input type="text"
data-autocomplete="http://…"
data-autocomplete-param-name="query_to_search" />
noResult is string type. This option is available since the v1.2. The default value is No result.
This option allows given a custom message when there isn't results after one search. The message is usable into the post.
CAUTION: If you override the post method, think at given this value when the response is empty.
This option is settable with two attributes, DOM and/or JavaScript.
//How set the message for a empty response
AutoComplete({noResult: "There isn't results for this search"});
<!-- HTML declaration -->
<input type="text"
data-autocomplete="http://…"
data-autocomplete-no-result="Nope Nope Nope… Bad entry" />
open is function type. Its purpose is to bind the LI items responses generate by the post method.
To override the method open, you must respect the prototype.
//Prototype: open method
void function(input, result);
//Default open function
{
open: function(input, result) {
//lambda is an anonymous function which take one argument. This argument is an HTML li object
var lambda = function(li) {
//We add a event tracker. When we click on this HTML li object
li.addEventListener("click", function(e) {
var li = e.currentTarget,
dataAutocompleteValueLabel = "data-autocomplete-value";
//We push the li value into the input, except if li own a alternative value.
input.value = li.hasAttribute(dataAutocompleteValueLabel) ? attr(li, dataAutocompleteValueLabel) : li.innerHTML;
//I push the input value in a input's attribute for stop the results show, while the input value doesn't change.
attr(input, {"data-autocomplete-old-value": input.value});
});
};
//We search all li items
var liS = result.getElementsByTagName("li");
//We bind all items
for (var i = liS.length - 1; i >= 0; i--) {
lambda(liS[i]);
}
}
}
post is function type. Its purpose is the method which insert results in the DOM. It creates the result menu. You can override this method in respect the prototype.
//Prototype: post method
boolean function(result, response, custParams);
{
//Default post function
post: function(result, response, custParams) {
//If an exception is throws, the result isn't JSON data.
try {
//Try parse like JSON data
response = JSON.parse(response);
var empty,
length = response.length,
li = domCreate("li"),
ul = domCreate("ul");
//If the response is a JSON array
if (Array.isArray(response)) {
//If there is results
if (length) {
//We reverse results if parameter is custom
if (custParams.limit < 0) {
response.reverse();
}
//While there is results, we show in inserting in DOM ul element
for (var i = 0; i < length && (i < Math.abs(custParams.limit) || !custParams.limit); i++) {
li.innerHTML = response[i];
ul.appendChild(li);
li = domCreate("li");
}
//If there isn't results, we give the parameters « noResult »
} else {
//If the response is an object or an array and that the response is empty, so this script is here, for the message no response.
empty = true;
//The class « locked » on a li element stop the click event
attr(li, {"class": "locked"});
li.innerHTML = custParams.noResult;
ul.appendChild(li);
}
}
//If the result is JSON Object
else {
var properties = Object.getOwnPropertyNames(response);
//Reverse result if limit parameter is custom
if (custParams.limit < 0) {
properties.reverse();
}
for (var propertie in properties) {
if (parseInt(propertie) < Math.abs(custParams.limit) || !custParams.limit) {
li.innerHTML = response[properties[propertie]];
attr(li, {"data-autocomplete-value": properties[propertie]});
ul.appendChild(li);
li = domCreate("li");
}
}
}
if (result.hasChildNodes()) {
result.childNodes[0].remove();
}
result.appendChild(ul);
return empty;
} catch (e) {
result.innerHTML = response;
}
}
}
pre is a function with purpose to modify id necessary the value before it send.
The default function is it :
{
pre: function(input) {
return input.value;
}
}
//Prototype
string function(input);
{
pre: function(input) {
//If the string length is < 2 chars
if (input.value.length < 2) {
//We cancel the request
return "";
}
return input.value;
}
}
The method select give possibility to custom the value to insert in your autocomplete input. Default, The method insert the li's value selected, and insert the same value in the input attribute data-autocomplete-old-value. This attribute allows to stop search when a value has been selected (without that it changes).
select: function(input, item) {
input.value = attr(item, "data-autocomplete-value", item.innerHTML);
attr(input, {"data-autocomplete-old-value": input.value});
}
If you want override this method, this is the parameters descriptions :
This feature isn't a argument to initialize your autocomplete but an event to send to reposition the results. This feature can be util if your DOM before your autocomplete input change. With this event, you can easily reposition the div.
var event = new Event('position');
document.querySelector("[data-autocomplete]").dispatchEvent(event);
With it, you can unbind and destroy all events applies on specific input. DOM element to puth results is deleted. All events are deleted.
var event = new Event('destroy');
document.querySelector("[data-autocomplete]").dispatchEvent(event);
You can easily implement a CSS for autocomplete.js. A snippet is available here on CodePen.
The version 1.7 has been validate by JSHint.
This is quality assurance.

This document explains the format of the MDB files. MDB files store the actual contents of a database record. The MDB file begins with a variable length header describing the overall database configuration. The header is followed by one or more variable length records. Every MDB file must have (generally as its first record, though it is not clear if this location is a requirement) a null record. This record is used by parent databases, if they exist, to specify a null value for one of their access keys.
The names given in the table below are sometimes used in implementations, but are not normative in any way.
| Name | Word Offset | Size (words) | Description |
|---|---|---|---|
| LengthOfHeader | 0 | 1 | Length of header in words, including this word. |
| Attributes | 1 | 1 | Attribute bits:
Records in a removable DB can be deleted even if there are records in the parent DB still referring to them. In a non-removable DB, this is not allowed. |
| Status | 2 | 1 | Status bits:
|
| NumOfKeys | 3 | 1 | 1 + the number of access keys, sometimes called "rules," per record. Essentially, the primary data field is being counted here, even though it is not an access key. (M) |
| NumOfFieldsPerRecord | 4 | 1 | Number of Fields per record. Includes the primary data field, access keys, and extra info fields. |
| RecordStart | 5 | 2 | Word pointer to start of first record in this file |
| pXIM | 7 | 2 | Word pointer to the XIM data |
| Reserved | 9 | 6 | Reserved |
| DB_ID | 15 | 1 | Database ID assigned by device DB server |
| pDB_Name | 16 | 2 | Word pointer to DB name |
| pParentDBFilename | 18 | 2 | Word pointer to DB filename |
| pRuleName1 | 20 | 2 | Word pointer to name of access key #1 |
| pRuleFilename1 | 22 | 2 | Word pointer to filename of child MDB for access key #1 |
| ... | ... | ... | ... |
| pRuleNameM | 20+4*(M-1) | 2 | Word pointer to name of access key #M |
| pRuleFilenameM | 22+4*(M-1) | 2 | Word pointer to filename of child MDB for access key #M |
| ... | ... | ... | ... |
| DB_Name | Variable | DB name (dd format) | |
| ParentDBFilename | Variable | DB filename (sz format) | |
| RuleName1 | Variable | Name of access key #1 (dd format) | |
| RuleFilename1 | 22 | Variable | Filename of child MDB file for access key #1 (sz format) |
| ... | ... | ... | ... |
| pRuleNameM | Variable | Name of access key #M (dd format) | |
| pRuleFilenameM | Variable | Filename of child MDB for access key #M (sz format) | |
| ... | ... | ... | ... |
| XIM | Variable | XIM data | |
| ... | ... | ... | ... |
| Signature | LengthOfHeader - 2 | 2 | Signature, "WOID" |
XIM data is used to control the menu system on the Neuros. Various databases are often associated with particular menus, and the XIM data stored in the MDB header controls what menu options are available and what they do. This documentation does not cover the structure of the XIM data block.
MDB Records are composed of three types of fields (always occuring in this order):
The number of each of these fields is fixed by the MDB header. There is one primary data field, (NumOfKeys - 1) access keys, and (NumOfFieldsPerRecord - NumOfKeys) extra info fields.
Fields are permitted to be multi-valued. This is used to support fields like "Playlist" in the audio database, which can have several values if a track is in multiple playlists.
Since fields can have variable length, some method must be used to mark where each field begins and ends. The method used in the MDB format is special delimiter words:
An example record in a database with all three types of fields, but without any multivalued fields, would have the following form:
Record Flag - 16-bit flag
|
| Primary Record Data (sz format) |
| 0x0023, Field delimiter |
| Access Key #1 (pointer) |
| 0x0023, Field delimiter |
| Access Key #2 (pointer) |
| 0x0023, Field delimiter |
| Extra Info #1 (integer) |
| 0x0023, Field delimiter |
| Extra Info #2 (sz data) |
| 0x0025, End of Record |
An example record in a database with all three types of fields, but with a multivalued fields, would have the following form:
| Record Flag |
| Primary Record Data (sz format) |
| 0x0023, Field delimiter |
| Access Key #1, Value #1 (pointer) |
| 0x0024, Bag delimiter |
| Access Key #1, Value #2 (pointer) |
| 0x0023, Field delimiter |
| Access Key #2 (pointer) |
| 0x0023, Field delimiter |
| Extra Info #1 (integer) |
| 0x0023, Field delimiter |
| Extra Info #2 (sz data) |
| 0x0025, End of Record |
Most child databases only have a primary data field, so they look like:
| Record Flag |
| Primary Record Data (sz format) |
| 0x0025, End of Record |
Every database is required to have a null record, generally the first record. This is a degenerate record with no fields used to represent null values in child databases. A parent will point to this record when the associated access key has a null (or empty) value:
| 0x8000, Record Flag (this record must not be deleted) |
| 0x0025, End of Record |

PureBasic - EntityAnimation
概要
Entities are objects composed of one mesh object and one material which can be freely moved and transformed in real-time. This library is provided to control the entity animation. The mesh associated to the entity needs to have a skeleton with some predefined animations.
InitEngine3D() should be called successfully before using the entity animation functions.

Welcome to my site! My name is Jonathan Street. I am fascinated by how the world works and enjoy experimenting to find the answers. I am currently studying kidney disease at the National Institutes of Health.
I frequently use programming and machine learning to answer questions I otherwise could not. I have been developing software since 2002 and enjoy helping others get started. I have previously taught python and machine learning and continue to host a monthly event for the python user group in Washington, D.C.
I try to keep this site updated with posts on the interesting things I do. Usually scientific articles and blog posts on the data and programming challenges I encounter. The site is part résumé and part journal.


2.5. Variables and Assignment
Rules for variables in Python are the same as they are in most other high-level languages inspired by (or more likely, written in) C. They are simply identifier names with an alphabetic first character "alphabetic" meaning upper-or lowercase letters, including the underscore ( _ ). Any additional characters may be alphanumeric or underscore. Python is case-sensitive, meaning that the identifier "cAsE" is different from "CaSe."
Python is dynamically typed, meaning that no pre-declaration of a variable or its type is necessary. The type (and value) are initialized on assignment. Assignments are performed using the equal sign.
>>> counter = 0
>>> miles = 1000.0
>>> name = 'Bob'
>>> counter = counter + 1
>>> kilometers = 1.609 * miles
>>> print '%f miles is the same as %f km' % (miles, kilometers)
1000.000000 miles is the same as 1609.000000 km
We have presented five examples of variable assignment. The first is an integer assignment followed by one each for floating point numbers, one for strings, an increment statement for integers, and finally, a floating point operation and assignment.
Python also supports augmented assignment, statements that both refer to and assign values to variables. You can take the following expression ...
...and use this shortcut instead:
Python does not support increment and decrement operators like the ones in C: n++ or --n. Because + and -- are also unary operators, Python will interpret --n as -(-n) == n, and the same is true for ++n.

Spurs sack Pochettino: He taught me so much – Alli hails Argentinian
by Sports DeskDele Alli was one of the first players to thank Mauricio Pochettino following Tottenham's decision to sack the Argentine coach, posting an emotional tribute on social media.
Spurs announced Pochettino's departure with the club sitting 14th in the Premier League and winless in five league matches, but the decision nevertheless sent shockwaves around European football.
Under Pochettino, Alli was handed his league debut for Tottenham in 2015-16, and the England midfielder went on to finish second in the Premier League under his guidance the following season.
Alli has made just four league starts for Spurs this season, scoring two goals, but he went on Twitter to reflect on the lessons learned under Pochettino's leadership following the news of his dismissal.
"I can't thank this man enough," Alli wrote.
"He's taught me so much and I'm so grateful for everything he's done for me."
Pochettino started Alli 28 times during the 2015-16 Premier League season and the playmaker has been a regular in his team ever since, when fit.
The club spoke of a "need to re-energise and look to deliver a positive season for our supporters" in the statement announcing Pochettino's departure, and Alli wished his former boss well.
"Good luck and hope to see you again my friend," Alli wrote.


Autonomous car tester offers guide for first responders
by Associated PressPHOENIX (AP) — Google spinoff Waymo is trying to educate emergency responders on how to deal with its autonomous vehicles.
Waymo released a training video on YouTube Thursday geared toward guiding public safety officials responding to incidents involving their self-driving cars.
The 14-minute instructional video advises how to put a car in manual mode and what precautions firefighters should take.
The video was done in conjunction with Waymo engineers and suburban Phoenix police and firefighters.
Waymo is among several companies that has been testing autonomous vehicle programs in Arizona.
The video comes two days after the National Transportation Safety Board found a distracted human safety driver caused a fatal crash of an autonomous Uber car.
The NTSB also condemned a lack of state and federal regulation of testing on public roads.

This document is a quick outline of the unusual form of assembly language used by the gc
suite of Go compilers (6g
, 8g
, etc.).
It is based on the input to the Plan 9 assemblers, which is documented in detail
on the Plan 9 site.
If you plan to write assembly language, you should read that document although much of it is Plan 9-specific.
This document provides a summary of the syntax and
describes the peculiarities that apply when writing assembly code to interact with Go.
The most important thing to know about Go's assembler is that it is not a direct representation of the underlying machine.
Some of the details map precisely to the machine, but some do not.
This is because the compiler suite (see
this description)
needs no assembler pass in the usual pipeline.
Instead, the compiler emits a kind of incompletely defined instruction set, in binary form, which the linker
then completes.
In particular, the linker does instruction selection, so when you see an instruction like MOV
what the linker actually generates for that operation might not be a move instruction at all, perhaps a clear or load.
Or it might correspond exactly to the machine instruction with that name.
In general, machine-specific operations tend to appear as themselves, while more general concepts like
memory move and subroutine call and return are more abstract.
The details vary with architecture, and we apologize for the imprecision; the situation is not well-defined.
The assembler program is a way to generate that intermediate, incompletely defined instruction sequence
as input for the linker.
If you want to see what the instructions look like in assembly for a given architecture, say amd64, there
are many examples in the sources of the standard library, in packages such as
runtime
and
math/big
.
You can also examine what the compiler emits as assembly code:
$ cat x.go package main func main() { println(3) } $ go tool 6g -S x.go # or: go build -gcflags -S x.go --- prog list "main" --- 0000 (x.go:3) TEXT main+0(SB),$8-0 0001 (x.go:3) FUNCDATA $0,gcargs·0+0(SB) 0002 (x.go:3) FUNCDATA $1,gclocals·0+0(SB) 0003 (x.go:4) MOVQ $3,(SP) 0004 (x.go:4) PCDATA $0,$8 0005 (x.go:4) CALL ,runtime.printint+0(SB) 0006 (x.go:4) PCDATA $0,$-1 0007 (x.go:4) PCDATA $0,$0 0008 (x.go:4) CALL ,runtime.printnl+0(SB) 0009 (x.go:4) PCDATA $0,$-1 0010 (x.go:5) RET , ...
The FUNCDATA
and PCDATA
directives contain information
for use by the garbage collector; they are introduced by the compiler.
To see what gets put in the binary after linking, add the -a
flag to the linker:

Some symbols, such as PC
, R0
and SP
, are predeclared and refer to registers.
There are two other predeclared symbols, SB
(static base) and FP
(frame pointer).
All user-defined symbols other than jump labels are written as offsets to these pseudo-registers.
The SB
pseudo-register can be thought of as the origin of memory, so the symbol foo(SB)
is the name foo
as an address in memory.
The FP
pseudo-register is a virtual frame pointer
used to refer to function arguments.
The compilers maintain a virtual frame pointer and refer to the arguments on the stack as offsets from that pseudo-register.
Thus 0(FP)
is the first argument to the function,
8(FP)
is the second (on a 64-bit machine), and so on.
When referring to a function argument this way, it is conventional to place the name
at the beginning, as in first_arg+0(FP)
and second_arg+8(FP)
.
Some of the assemblers enforce this convention, rejecting plain 0(FP)
and 8(FP)
.
For assembly functions with Go prototypes, go vet
will check that the argument names
and offsets match.
The SP
pseudo-register is a virtual stack pointer
used to refer to frame-local variables and the arguments being
prepared for function calls.
It points to the top of the local stack frame, so references should use negative offsets
in the range [−framesize, 0):
x-8(SP)
, y-4(SP)
, and so on.
On architectures with a real register named SP
, the name prefix distinguishes
references to the virtual stack pointer from references to the architectural SP
register.
That is, x-8(SP)
and -8(SP)
are different memory locations:
the first refers to the virtual stack pointer pseudo-register, while the second refers to the
hardware's SP
register.
Instructions, registers, and assembler directives are always in UPPER CASE to remind you
that assembly programming is a fraught endeavor.
(Exceptions: the m
and g
register renamings on ARM.)
In Go object files and binaries, the full name of a symbol is the
package path followed by a period and the symbol name:
fmt.Printf
or math/rand.Int
.
Because the assembler's parser treats period and slash as punctuation,
those strings cannot be used directly as identifier names.
Instead, the assembler allows the middle dot character U+00B7
and the division slash U+2215 in identifiers and rewrites them to
plain period and slash.
Within an assembler source file, the symbols above are written as
fmt·Printf
and math∕rand·Int
.
The assembly listings generated by the compilers when using the -S
flag
show the period and slash directly instead of the Unicode replacements
required by the assemblers.
Most hand-written assembly files do not include the full package path
in symbol names, because the linker inserts the package path of the current
object file at the beginning of any name starting with a period:
in an assembly source file within the math/rand package implementation,
the package's Int function can be referred to as ·Int
.
This convention avoids the need to hard-code a package's import path in its
own source code, making it easier to move the code from one location to another.
The assembler uses various directives to bind text and data to symbol names.
For example, here is a simple complete function definition. The TEXT
directive declares the symbol runtime·profileloop
and the instructions
that follow form the body of the function.
The last instruction in a TEXT
block must be some sort of jump, usually a RET
(pseudo-)instruction.
(If it's not, the linker will append a jump-to-itself instruction; there is no fallthrough in TEXTs
.)
After the symbol, the arguments are flags (see below)
and the frame size, a constant (but see below):
TEXT runtime·profileloop(SB),NOSPLIT,$8 MOVQ $runtime·profileloop1(SB), CX MOVQ CX, 0(SP) CALL runtime·externalthreadhandler(SB) RET
In the general case, the frame size is followed by an argument size, separated by a minus sign.
(It's not an subtraction, just idiosyncratic syntax.)
The frame size $24-8
states that the function has a 24-byte frame
and is called with 8 bytes of argument, which live on the caller's frame.
If NOSPLIT
is not specified for the TEXT
,
the argument size must be provided.
Note that the symbol name uses a middle dot to separate the components and is specified as an offset from the
static base pseudo-register SB
.
This function would be called from Go source for package runtime
using the
simple name profileloop
.
For DATA
directives, the symbol is followed by a slash and the number
of bytes the memory associated with the symbol occupies.
The arguments are optional flags and the data itself.
For instance,
DATA runtime·isplan9(SB)/4, $1
declares the local symbol runtime·isplan9
of size 4 and value 1.
Again the symbol has the middle dot and is offset from SB
.
The GLOBL
directive declares a symbol to be global.
The arguments are optional flags and the size of the data being declared as a global,
which will have initial value all zeros unless a DATA
directive
has initialized it.
The GLOBL
directive must follow any corresponding DATA
directives.
This example
GLOBL runtime·tlsoffset(SB),$4
declares runtime·tlsoffset
to have size 4.
There may be one or two arguments to the directives.
If there are two, the first is a bit mask of flags,
which can be written as numeric expressions, added or or-ed together,
or can be set symbolically for easier absorption by a human.
Their values, defined in the file src/cmd/ld/textflag.h
, are:
NOPROF
= 1
TEXT
items.)
Don't profile the marked function. This flag is deprecated.
DUPOK
= 2
NOSPLIT
= 4
TEXT
items.)
Don't insert the preamble to check if the stack must be split.
The frame for the routine, plus anything it calls, must fit in the
spare space at the top of the stack segment.
Used to protect routines such as the stack splitting code itself.
RODATA
= 8
DATA
and GLOBL
items.)
Put this data in a read-only section.
NOPTR
= 16
DATA
and GLOBL
items.)
This data contains no pointers and therefore does not need to be
scanned by the garbage collector.
WRAPPER
= 32
TEXT
items.)
This is a wrapper function and should not count as disabling recover
.
It is impractical to list all the instructions and other details for each machine.
To see what instructions are defined for a given machine, say 32-bit Intel x86,
look in the top-level header file for the corresponding linker, in this case 8l
.
That is, the file $GOROOT/src/cmd/8l/8.out.h
contains a C enumeration, called as
,
of the instructions and their spellings as known to the assembler and linker for that architecture.
In that file you'll find a declaration that begins
enum as { AXXX, AAAA, AAAD, AAAM, AAAS, AADCB, ...
Each instruction begins with a initial capital A
in this list, so AADCB
represents the ADCB
(add carry byte) instruction.
The enumeration is in alphabetical order, plus some late additions (AXXX
occupies
the zero slot as an invalid instruction).
The sequence has nothing to do with the actual encoding of the machine instructions.
Again, the linker takes care of that detail.
One detail evident in the examples from the previous sections is that data in the instructions flows from left to right:
MOVQ
$0,
CX
clears CX
.
This convention applies even on architectures where the usual mode is the opposite direction.
Here follows some descriptions of key Go-specific details for the supported architectures.
The runtime pointers to the m
and g
structures are maintained
through the value of an otherwise unused (as far as Go is concerned) register in the MMU.
A OS-dependent macro get_tls
is defined for the assembler if the source includes
an architecture-dependent header file, like this:
#include "zasm_GOOS_GOARCH.h"
Within the runtime, the get_tls
macro loads its argument register
with a pointer to a pair of words representing the g
and m
pointers.
The sequence to load g
and m
using CX
looks like this:
get_tls(CX) MOVL g(CX), AX // Move g into AX. MOVL m(CX), BX // Move m into BX.
The assembly code to access the m
and g
pointers is the same as on the 386, except it uses MOVQ
rather than
MOVL
:
get_tls(CX) MOVQ g(CX), AX // Move g into AX. MOVQ m(CX), BX // Move m into BX.
The registers R9
, R10
, and R11
are reserved by the compiler and linker.
R9
and R10
point to the m
(machine) and g
(goroutine) structures, respectively.
Within assembler source code, these pointers must be referred to as m
and g
;
the names R9
and R10
are not recognized.
To make it easier for people and compilers to write assembly, the ARM linker
allows general addressing forms and pseudo-operations like DIV
or MOD
that may not be expressible using a single hardware instruction.
It implements these forms as multiple instructions, often using the R11
register
to hold temporary values.
Hand-written assembly can use R11
, but doing so requires
being sure that the linker is not also using it to implement any of the other
instructions in the function.
When defining a TEXT
, specifying frame size $-4
tells the linker that this is a leaf function that does not need to save LR
on entry.
The name SP
always refers to the virtual stack pointer described earlier.
For the hardware register, use R13
.
The assemblers are designed to support the compiler so not all hardware instructions
are defined for all architectures: if the compiler doesn't generate it, it might not be there.
If you need to use a missing instruction, there are two ways to proceed.
One is to update the assembler to support that instruction, which is straightforward
but only worthwhile if it's likely the instruction will be used again.
Instead, for simple one-off cases, it's possible to use the BYTE
and WORD
directives
to lay down explicit data into the instruction stream within a TEXT
.
Here's how the 386 runtime defines the 64-bit atomic load function.
// uint64 atomicload64(uint64 volatile* addr); // so actually // void atomicload64(uint64 *res, uint64 volatile *addr); TEXT runtime·atomicload64(SB), NOSPLIT, $0-8 MOVL 4(SP), BX MOVL 8(SP), AX // MOVQ (%EAX), %MM0 BYTE $0x0f; BYTE $0x6f; BYTE $0x00 // MOVQ %MM0, 0(%EBX) BYTE $0x0f; BYTE $0x7f; BYTE $0x03 // EMMS BYTE $0x0F; BYTE $0x77 RET
