Fix non-intel arch builds (cpuid.h header) 2023-02-09 20:54:46 +01:00

Fix CPUID to detect AVX512F 
CPUID is part of x86_64 ISA to query CPU features. In order to determine
AVX512F ISA extension, EAX and ECX needs to be set to 7 and 0
respectively before invoking `cpuid` instruction. This commit also
removes inline assembly for __cpuid in favor of using compiler provided
intrinsic functions. Both GCC and clang provides __cpuid like function
via __cpuid_count intrinsic.

This commit also creates a portable wrapper over compiler intrinsic
functions, __cpuid and __cpuidex. `cpuid' provides base level ISA query
and `cpuidex` provides extra extension information like AVX512F. These
wrappers lean towards MSVC like API.

Add support for Intel/AMD's FMA extension 
By supporting FMA extension, the number of instruction needed
for multiply accumulate to mix channels are reduced. Since,
this extension has been around since middle of 2012, more
computers have this instruction set available.

ed09a68f24 Fix for conflicting definition of _xgetbv with mingw-w64 >= 5 
Simplify the #ifdef logic so it is easier to follow and add exceptions in the
future if necessary.

5a41b86028 fix __cpuid() on x86 
The previous version used memory operands that gcc (probably dependent
on optimization flags and/or version) could address relative to the
stack pointer, but pushing %ebx onto the stack changed it. Here, the
address of the regs array is put into %esi and the individual members
are written into directly.

6cb742c289 windows 32bit asm/fpu support. 
This still leaves cache_aligned_malloc() in
libs/pbd/malign.cc pending _aligned_free (windows crashes when using
free() on memory allocated with _aligned_malloc()).

So far however there seems to be no issue with default malloc
for audio+midi buffers on win32…
