## 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](https://translate.google.com/?hl=ja&sl=ja&tl=en&text=%E9%96%8B%E9%97%A2&op=translate), 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.
|
||
|
||
### 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.
|
||
- 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 cast `imm` 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](#exception-less-mode)
|
||
- `XBYAK_USE_MMAP_ALLOCATOR` will be defined on Linux/macOS unless `XBYAK_DONT_USE_MMAP_ALLOCATOR` is defined.
|
||
|
||
### Supported OS
|
||
|
||
- Windows (Xp, Vista, 7, 10, 11) (32 / 64 bit)

||
- Linux (32 / 64 bit)
|
||
- macOS (Intel CPU)
|
||
|
||
