[Ffmpeg-devel] ARCH_X86 vs ARCH_X86_32 vs ARCH_X86_64

[Diego Biurrun]

I'd like to introduce a define that encompasses both x86 and x86_64 to
simplify statements like

  #if defined(ARCH_X86) || defined(ARCH_X86_64)

of which we have tons in the code and be able to use it in the Makefiles
where or expressions are troublesome.

My first idea was to rename ARCH_X86 --> ARCH_X86_32 and use ARCH_X86
for the general case.  It seems like the cleanest and most
straightforward solution to me, but I'm getting second thoughts.  I'm
afraid that ARCH_X86 semantics are kind of set in stone through years of
usage (in autoconf as well).

Thoughts?
