Update M4 macros #32

Open noloader opened 4 years ago

noloader commented 4 years ago

This commit updates the M4 macros.

The ax_ folks fixed a bug in ax_gcc_x86_cpuid.m4 when ebx/rbx was not saved and restored. There were probably other fixes, too.

ax_ext.m4 supports a lot more processors and features. For example, XOP is now detected properly on non-AMD machines.
