Xbyak 5.67 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
=============
# Xbyak 5.77 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
Abstract
-------------
## Abstract
This is a header file which enables dynamically to assemble x86(IA32), x64(AMD64, x86-64) mnemonic.
Feature
-------------
header file only
you can use Xbyak's functions at once if xbyak.h is included.
## Feature
* header file only
* Intel/MASM like syntax
* fully support AVX-512
### Supported Instructions Sets
**Note**: Xbyak uses and(), or(), xor(), not() functions, so `-fno-operator-names` option is necessary for gcc/clang.
MMX/MMX2/SSE/SSE2/SSE3/SSSE3/SSE4/FPU(*partial*)/AVX/AVX2/FMA/VEX-encoded GPR/AVX-512
Or define `XBYAK_NO_OP_NAMES` before including `xbyak.h` and use and_(), or_(), xor_(), not_() instead of them.
and_(), or_(), xor_(), not_() are always available.
`XBYAK_NO_OP_NAMES` will be defined in the feature version.
### Supported OS
* Windows Xp, Vista, Windows 7(32bit, 64bit)
* Windows Xp, Vista, Windows 7, Windows 10(32bit, 64bit)
* Linux(32bit, 64bit)
* Intel Mac OSX
* Intel macOS
### Supported Compilers
* Visual Studio C++ VC2012 or later
* gcc 4.7 or later
* clang 3.3
* cygwin gcc 4.5.3
* icc 7.2
Almost C++03 or later compilers for x86/x64 such as Visual Studio, g++, clang++, Intel C++ compiler and g++ on mingw/cygwin.
>Note: Xbyak uses and(), or(), xor(), not() functions, so "-fno-operator-names" option is required on gcc.
Or define XBYAK_NO_OP_NAMES and use and_(), or_(), xor_(), not_() instead of them.
and_(), or_(), xor_(), not_() are always available.
## Install
Install
-------------
The following files are necessary. Please add the path to your compile directories.
The following files are necessary. Please add the path to your compile directory.
* xbyak.h
* xbyak_mnemonic.h
* xbyak_util.h
Linux:
```
make install
```
make install
These files are copied into `/usr/local/include/xbyak`.
These files are copied into /usr/local/include/xbyak
## How to use it
New Feature
-------------
Inherit `Xbyak::CodeGenerator` class and make the class method.
```
#define XBYAK_NO_OP_NAMES
#include <xbyak/xbyak.h>
Add support for AVX-512 instruction set.
struct Code : Xbyak::CodeGenerator {
Code(int x)
{
mov(eax, x);
ret();
}
};
```
Make an instance of the class and get the function
pointer by calling `getCode()` and call it.
```
Code c(5);
int (*f)() = c.getCode<int (*)()>();
printf("ret=%d\n", f()); // ret = 5
```
Syntax
-------------
Make Xbyak::CodeGenerator and make the class method and get the function
pointer by calling cgetCode() and casting the return value.
NASM Xbyak
mov eax, ebx --> mov(eax, ebx);
inc ecx inc(ecx);
ret --> ret();
### Addressing
(ptr|dword|word|byte) [base + index * (1|2|4|8) + displacement]
[rip + 32bit disp] ; x64 only
NASM Xbyak
mov eax, [ebx+ecx] --> mov (eax, ptr[ebx+ecx]);
test byte [esp], 4 --> test (byte [esp], 4);
How to use Selector(Segment Register)
>Note: Segment class is not derived from Operand.
## Syntax
Similar to MASM/NASM syntax with parentheses.
```
mov eax, [fs:eax] --> putSeg(fs); mov(eax, ptr [eax]);
NASM Xbyak
mov eax, ebx --> mov(eax, ebx);
inc ecx inc(ecx);
ret --> ret();
```
## Addressing
Use `qword`, `dword`, `word` and `byte` if it is necessary to specify the size of memory,
otherwise use `ptr`.
```
(ptr|qword|dword|word|byte) [base + index * (1|2|4|8) + displacement]
[rip + 32bit disp] ; x64 only
NASM Xbyak
mov eax, [ebx+ecx] --> mov(eax, ptr [ebx+ecx]);
mov al, [ebx+ecx] --> mov(al, ptr [ebx + ecx]);
test byte [esp], 4 --> test(byte [esp], 4);
inc qword [rax] --> inc(qword [rax]);
```
**Note**: `qword`, ... are member variables, then don't use `dword` as unsigned int type.
### How to use Selector (Segment Register)
```
mov eax, [fs:eax] --> putSeg(fs);
mov(eax, ptr [eax]);
mov ax, cs --> mov(ax, cs);
```
**Note**: Segment class is not derived from `Operand`.
>you can use ptr for almost memory access unless you specify the size of memory.
## AVX
>dword, word and byte are member variables, then don't use dword as unsigned int, for example.
### AVX
vaddps(xmm1, xmm2, xmm3); // xmm1 <- xmm2 + xmm3
vaddps(xmm2, xmm3, ptr [rax]); // use ptr to access memory
vgatherdpd(xmm1, ptr [ebp+123+xmm2*4], xmm3);
*Remark*
The omitted destination syntax as the following ss disabled.
```
vaddps(xmm2, xmm3); // xmm2 <- xmm2 + xmm3
vaddps(xmm1, xmm2, xmm3); // xmm1 <- xmm2 + xmm3
vaddps(xmm2, xmm3, ptr [rax]); // use ptr to access memory
vgatherdpd(xmm1, ptr [ebp + 256 + xmm2*4], xmm3);
```
define `XBYAK_ENABLE_OMITTED_OPERAND` if you use it for backward compatibility.
**Note**:
If `XBYAK_ENABLE_OMITTED_OPERAND` is defined, then you can use two operand version for backward compatibility.
But the newer version will not support it.
```
vaddps(xmm2, xmm3); // xmm2 <- xmm2 + xmm3
```
### AVX-512
## AVX-512
```
vaddpd zmm2, zmm5, zmm30 --> vaddpd(zmm2, zmm5, zmm30);

Remark
* k1, ..., k7 are new opmask registers.
### Remark
* `k1`, ..., `k7` are opmask registers.
* use `| T_z`, `| T_sae`, `| T_rn_sae`, `| T_rd_sae`, `| T_ru_sae`, `| T_rz_sae` instead of `,{z}`, `,{sae}`, `,{rn-sae}`, `,{rd-sae}`, `,{ru-sae}`, `,{rz-sae}` respectively.
* `k4 | k3` is different from `k3 | k4`.
* use `ptr_b` for broadcast `{1toX}`. X is automatically determined.
* specify xword/yword/zword(_b) for m128/m256/m512 if necessary.
* specify `xword`/`yword`/`zword(_b)` for m128/m256/m512 if necessary.
### Label
## Label
Two kinds of Label are supported. (String literal and Label class).

* Call `hasUndefinedLabel()` to verify your code has no undefined label.
* you can use a label for immediate value of mov like as `mov(eax, "L2")`.
#### 1. support @@, @f, @b like MASM
### Support `@@`, `@f`, `@b` like MASM
L("@@"); // <A>
jmp("@b"); // jmp to <A>
jmp("@f"); // jmp to <B>
L("@@"); // <B>
jmp("@b"); // jmp to <B>
mov(eax, "@b");
jmp(eax); // jmp to <B>
```
L("@@"); // <A>
jmp("@b"); // jmp to <A>
jmp("@f"); // jmp to <B>
L("@@"); // <B>
jmp("@b"); // jmp to <B>
mov(eax, "@b");
jmp(eax); // jmp to <B>
```
#### 2. localization of label by calling inLocalLabel(), outLocallabel().
### Local label
labels begining of period between inLocalLabel() and outLocalLabel()
are dealed with local label.
inLocalLabel() and outLocalLabel() can be nested.
Label symbols beginning with a period between `inLocalLabel()` and `outLocalLabel()`
are treated as a local label.
`inLocalLabel()` and `outLocalLabel()` can be nested.
void func1()
{
inLocalLabel();
L(".lp"); // <A> ; local label
...
jmp(".lp"); // jmpt to <A>
L("aaa"); // global label
outLocalLabel();
}
```
void func1()
{
inLocalLabel();
L(".lp"); // <A> ; local label
...
jmp(".lp"); // jmp to <A>
L("aaa"); // global label <C>
outLocalLabel();
void func2()
{
inLocalLabel();
L(".lp"); // <B> ; local label
func1();
jmp(".lp"); // jmp to <B>
inLocalLabel();
}
inLocalLabel();
L(".lp"); // <B> ; local label
func1();
jmp(".lp"); // jmp to <B>
inLocalLabel();
jmp("aaa"); // jmp to <C>
}
```
### Label class
L() and jxx() functions support a new Label class.
`L()` and `jxx()` support Label class.
Label label1, label2;
L(label1);
...
jmp(label1);
...
jmp(label2);
...
L(label2);
```
Xbyak::Label label1, label2;
L(label1);
...
jmp(label1);
...
jmp(label2);
...
L(label2);
```
Moreover, assignL(dstLabel, srcLabel) method binds dstLabel with srcLabel.
Use `putL` for jmp table
```
Label labelTbl, L0, L1, L2;
mov(rax, labelTbl);
// rdx is an index of jump table
jmp(ptr [rax + rdx * sizeof(void*)]);
L(labelTbl);
putL(L0);
putL(L1);
putL(L2);
L(L0);
....
L(L1);
....
```
Label label1, label2;
L(label1);
...
jmp(label2);
...
assignL(label2, label1); // label2 <= label1
`assignL(dstLabel, srcLabel)` binds dstLabel with srcLabel.
The above jmp opecode jumps label1.
```
Label label2;
Label label1 = L(); // make label1 ; same to Label label1; L(label1);
...
jmp(label2); // label2 is not determined here
...
assignL(label2, label1); // label2 <- label1
```
The `jmp` in the above code jumps to label1 assigned by `assignL`.
* Restriction:
* srcLabel must be used in L().
* dstLabel must not be used in L().
**Note**:
* srcLabel must be used in `L()`.
* dstLabel must not be used in `L()`.
Label::getAddress() returns the address specified by the label instance and 0 if not specified.
`Label::getAddress()` returns the address specified by the label instance and 0 if not specified.

### Code size
The default max code size is 4096 bytes. Please set it in constructor of CodeGenerator() if you want to use large size.
class Quantize : public Xbyak::CodeGenerator {
public:
Quantize()
: CodeGenerator(8192)
{
}
...
};
## Code size
The default max code size is 4096 bytes.
Specify the size in constructor of `CodeGenerator()` if necessary.
### use user allocated memory
```
class Quantize : public Xbyak::CodeGenerator {
public:
Quantize()
: CodeGenerator(8192)
{
}
...
};
```
## User allocated memory
You can make jit code on prepaired memory.
class Sample : public Xbyak::CodeGenerator {
public:
Sample(void *userPtr, size_t size)
: Xbyak::CodeGenerator(size, userPtr)
{
...
}
};
Call `setProtectModeRE` yourself to change memory mode if using the prepaired memory.
const size_t codeSize = 1024;
uint8 buf[codeSize + 16];
// get 16-byte aligned address
uint8 *p = Xbyak::CodeArray::getAlignedAddress(buf);
// append executable attribute to the memory
Xbyak::CodeArray::protect(p, codeSize, true);
// construct your jit code on the memory
Sample s(p, codeSize);
>See *sample/test0.cpp*
AutoGrow
-------------
Under `AutoGrow` mode, Xbyak extends memory automatically if necessary.
Call ready() before calling getCode() to calc address of jmp.
```
struct Code : Xbyak::CodeGenerator {
Code()
: Xbyak::CodeGenerator(<default memory size>, Xbyak::AutoGrow)
{
...
}
};
uint8_t alignas(4096) buf[8192]; // C++11 or later
struct Code : Xbyak::CodeGenerator {
Code() : Xbyak::CodeGenerator(sizeof(buf), buf)
{
mov(rax, 123);
ret();
}
};
int main()
{
Code c;
c.ready(); // Don't forget to call this function
c.setProtectModeRE(); // set memory to Read/Exec
printf("%d\n", c.getCode<int(*)()>()());
}
```
>Don't use the address returned by getCurr() before calling ready().
>It may be invalid address.
>RESTRICTION : rip addressing is not supported in AutoGrow
Macro
-------------
**Note**: See [sample/test0.cpp](sample/test0.cpp).
### AutoGrow
The memory region for jit is automatically extended if necessary when `AutoGrow` is specified in a constructor of `CodeGenerator`.
Call `ready()` or `readyRE()` before calling `getCode()` to fix jump address.
```
struct Code : Xbyak::CodeGenerator {
Code()
: Xbyak::CodeGenerator(<default memory size>, Xbyak::AutoGrow)
{
...
}
};
Code c;
// generate code for jit
c.ready(); // mode = Read/Write/Exec
```
**Note**:
* Don't use the address returned by `getCurr()` before calling `ready()` because it may be invalid address.
### Read/Exec mode
Xbyak set Read/Write/Exec mode to memory to run jit code.
If you want to use Read/Exec mode for security, then specify `DontSetProtectRWE` for `CodeGenerator` and
call `setProtectModeRE()` after generating jit code.
```
struct Code : Xbyak::CodeGenerator {
Code()
: Xbyak::CodeGenerator(4096, Xbyak::DontSetProtectRWE)
{
mov(eax, 123);
ret();
}
};
Code c;
c.setProtectModeRE();
...
```
Call `readyRE()` instead of `ready()` when using `AutoGrow` mode.
See [protect-re.cpp](sample/protect-re.cpp).

・read/execモード
デフォルトのCodeGeneratorはコンストラクト時にJIT用の領域をread/write/execモードに設定して利用します。
コード生成時はread/writeでコード実行時にはread/execにしたい場合、次のようにしてください。
struct Code : Xbyak::CodeGenerator {
Code()
: Xbyak::CodeGenerator(4096, Xbyak::DontUseProtect) // JIT領域をread/writeのままコード生成
{
mov(eax, 123);
ret();
}
};
Code c;
c.setProtectModeRE(); // read/execモードに変更
// JIT領域を実行
AutoGrowの場合はreadyの代わりにreadyRE()を読んでください。
struct Code : Xbyak::CodeGenerator {
Code()
: Xbyak::CodeGenerator(4096, Xbyak::AutoGrow) // JIT領域をread/writeのままコード生成
{
mov(eax, 123);
ret();
}
};
Code c;
c.readyRE(); // read/exeモードに変更
// JIT領域を実行
setProtectModeRW()を呼ぶと領域が元のread/execモードに戻ります。
その他詳細は各種サンプルを参照してください。
