* ax_gcc_x86_cpu_supports.m4: Fix AC_LANG clobbered...Kip2021-08-101-1/+2
| | | AX_GCC_X86_CPU_SUPPORTS expands _AX_GCC_X86_CPU_INIT, which in turn expands an AC_LANG_PUSH([C]) without a corresponding AC_LANG_POP([C])...

* macros for X86 instruction set testsdryman2016-03-211-0/+104
| | | | | | | | | | Added two macros: ax_check_x86_features.m4, and ax_gcc_x86_cpu_supports.m4 It checks if the host cpu supports various instruction set: mmx, sse, popcnt, avx, avx2, etc. If the instruction were supported, it would export HAVE_XXX_INSTRUCTIONS C preprocessor macros and add the instruction set flag to X86_FEATURES_CFLAGS variable. By default it would also set CFLAGS, but this can be disabled by the ACTION-IF-FOUND hook.

The build process requires python, the python StringTemplate module, and preferably SCons. A make-based build exists, but it is really slow and awkward, compared to the SConstruct file.
