# Xbyak 5.97 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
# Xbyak 5.991 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
## 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

If you want to use them, then specify `-fno-operator-names` option to gcc/clang.
### News
- 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)
