Add CXX_32 and CXX_64 variables in the makefiles

Instead of explicitly passing -m32 and -m64 to the CXX invocation,
define CXX_32 and CXX_64 as "CXX -m32" and "CXX -m64", respectively.

This allows easily using a cross GCC toolchain instead of GCC's multilib
support, for example by defining CXX_32=i686-linux-gnu-gcc, and
CXX_64=x86_64-linux-gnu-gcc.

See
<https://lists.debian.org/msgid-search/20250316194848.GA2297362@subdivi.de>
and related messages for some more context on why multilib (-m32 and
-m64) might get removed from Debian in the future, in favour of cross
compilers.

Xbyak 7.24.1 Badge Build

A JIT assembler for x86/x64 architectures supporting advanced instruction sets up to AVX10.2

Menu

Abstract

Xbyak is a C++ header-only library that enables dynamic assembly of x86/x64 instructions using mnemonics.

The pronunciation of Xbyak is /kʌɪbjæk/ (kai-byak).

The name is derived from the Japanese word 開闢 (kaibyaku), which means “the beginning of the world” or “creation”.

Features

  • Header-only library
  • Intel/MASM-like syntax
  • Full support for AVX-512, APX, and AVX10.2

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

News

  • Support AVX10.2
  • Support xresldtrk/xsusldtrk
  • Support RAO-INT for APX
  • Support AVX10 detection, AESKLE, WIDE_KL, KEYLOCKER, KEYLOCKER_WIDE
  • Support APX except for a few instructions
  • 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
  • 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.
