From d3eced2687b68659716c7f4729e4bd31674934f7 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 14 Oct 2012 08:47:56 +0000 Subject: sdl_gfx: don't use --enable-mmx on x86_64 Even though the MMX instructions are available on x86_64 processors, the MMX code in sdl_gfx is written in IA32-specific assembly code, and therefore does not build on x86_64. It generates the following build issues: SDL_imageFilter.c: Assembler messages: SDL_imageFilter.c:34: Error: `pusha' is not supported in 64-bit mode SDL_imageFilter.c:38: Error: `popa' is not supported in 64-bit mode SDL_imageFilter.c:77: Error: `pusha' is not supported in 64-bit mode SDL_imageFilter.c:93: Error: `popa' is not supported in 64-bit mode [...] We fix this by only enabling MMX support in this package when the processor supports MMX *and* it is a IA32 compatible processor.
