Bug 736

Summary: SSE instructions in MMX assembly routines, failing to build
Product: SDL Reporter: namida1
Component: videoAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: HG 2.0   
Hardware: x86   
OS: All   

Description namida1 2009-05-03 07:27:06 UTC 
In video/SDL_blit_copy.c in the MMX routines there is usage of the prefetch mnemonics causing build to fail when disabling SSE. 
that is: /autogen.sh --disable-3dnow --disable-sse --disable-sse2.
commenting out the prefetch caused SDL_blit_copy to compile but giving undefined references when linking programs against the built SDL with mm_stream not defined which again is an SSE instruction.
