Xbyak 2.992 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
-----------------------------------------------------------------------------
<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.
MMX/MMX2/SSE/SSE2/SSE3/SSSE3/SSE4/FPU(partial)/AVX are available.
Windows Xp(32bit, 64bit), Vista, Linux(32bit, 64bit), Intel Mac ready
support Visual Studio C++ 2005 Express Ed., VC2008 Pro, VC2010,
mingw 3.4.2, icc 7.2, gcc 4.5, and so on.
Note: "-fno-operator-names" option is required on gcc to avoid analyzing
"and", "or", etc. as operators.
-----------------------------------------------------------------------------
<Install>
The following files are necessary. Please add the path to your compile
directories.
xbyak.h
xbyak_bin2hex.h
xbyak_mnemonic.h
Linux:
>make install
These files are copied into /usr/local/include/xbyak .
-----------------------------------------------------------------------------
<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);
NB. dword, word and byte are class members, then don't use dword as
unsigned int, for example.
AVX
You can omit a destination for almost 3-op mnemonics.
vaddps(xmm1, xmm2, xmm3); // xmm1 <- xmm2 + xmm3
vaddps(xmm2, xmm3); // xmm2 <- xmm2 + xmm3
Label
L("L1");
jmp ("L1");
jmp ("L2");
...
a few mnemonics(8-bit displacement jmp)
...
L("L2");
jmp ("L3", T_NEAR);
...
a lot of mnemonics(32-bit displacement jmp)
...
L("L3");
Call hasUndefinedLabel() to verify your code has no undefined label.
1. support @@, @f, @b like MASM
L("@@"); // <A>
jmp("@b"); // jmp to <A>
jmp("@f"); // jmp to <B>
L("@@"); // <B>
jmp("@b"); // jmp to <B>
2. localization of label by calling inLocalLabel(), outLocallabel()
void func1()
{
inLocalLabel();
L(".lp"); // <A>
...
jmp(".lp"); // jmpt to <A>
outLocalLabel();
}
void func2()
{
L(".lp"); // <B>
func1();
jmp(".lp"); // jmp to <B>
}
Code size
The default max code size is 2048 bytes. Please set it in constructor of
CodeGenerator() if you want to use large size.
class Quantize : public Xbyak::CodeGenerator {
public:
Quantize()
: CodeGenerator(8192)
{
}
...
};
See main.cpp
-----------------------------------------------------------------------------
<Macro>
XBYAK32 is defined on 32bit.
XBYAK64 is defined on 64bit.
XBYAK64_WIN is defined on 64bit Windows
XBYAK64_GCC is defined on 64bit gcc
-----------------------------------------------------------------------------
<Sample>
test0.cpp ; tiny sample of Xbyak(x86, x64)
quantize.cpp ; JIT optimized quantization by fast division(x86 only)
calc.cpp ; assemble and estimate a given polynomial(x86, x64)
bf.cpp ; JIT brainfuck(x86, x64)
-----------------------------------------------------------------------------
<Remark>
The current version does not support 3D Now!, 80bit FPU load/store
and some special mnemonics.
Please mail to me if necessary.
