Xbyak 6.61

A C++ JIT assembler for x86 (IA32), x64 (AMD64, x86-64)

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.

News

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
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)

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.
