Xbyak 6.73
A C++ JIT assembler for x86 (IA32), x64 (AMD64, x86-64)
Menu
Abstract
Xbyak is a C++ header library that enables dynamically to assemble x86(IA32), x64(AMD64, x86-64) mnemonic.
The pronunciation of Xbyak is kəi-bja-k
.
It is named from a Japanese word 開闢, which means the beginning of the world.
Feature
- header file only
- Intel/MASM like syntax
- fully support AVX-512
Note:
Use and_()
, or_()
, ... instead of and()
, or()
.
If you want to use them, then specify -fno-operator-names
option to gcc/clang.
Derived Projects
- Xbyak_aarch64 : for AArch64
- Xbyak_riscv : for RISC-V
News
- add amx_fp16/avx_vnni_int8/avx_ne_convert/avx-ifma
- add movdiri, movdir64b, clwb, cldemote
- WAITPKG instructions (tpause, umonitor, umwait) are supported.
- MmapAllocator supports memfd with user-defined strings. see sample/memfd.cpp
- strictly check address offset disp32 in a signed 32-bit integer. e.g.,
ptr[(void*)0xffffffff]
causes an error.- define
XBYAK_OLD_DISP_CHECK
if you need an old check, but the option will be remoevd.
- define
- add
jmp(mem, T_FAR)
,call(mem, T_FAR)
retf()
for far absolute indirect jump. - vnni instructions such as vpdpbusd supports vex encoding.
- (break backward compatibility)
push(byte, imm)
(resp.push(word, imm)
) forces to castimm
to 8(resp. 16) bit. - (Windows)
#include <winsock2.h>
has been removed from xbyak.h, so add it explicitly if you need it. - support exception-less mode see. Exception-less mode
XBYAK_USE_MMAP_ALLOCATOR
will be defined on Linux/macOS unlessXBYAK_DONT_USE_MMAP_ALLOCATOR
is defined.
Supported OS
- Windows (Xp, Vista, 7, 10, 11) (32 / 64 bit)
- Linux (32 / 64 bit)
- macOS (Intel CPU)
Supported Compilers
Almost C++03 or later compilers for x86/x64 such as Visual Studio, g++, clang++, Intel C++ compiler and g++ on mingw/cygwin.
