Description srrijkers 2007-11-27 20:45:32 UTC

Without -fomit-frame-pointer set (which libtheora-1,0_beta2-flags.patch strips from configure.in) compilation results in the following error:

enc/x86_32/dct_decode_mmx.c: In function 'FilterHoriz__mmx':
enc/x86_32/dct_decode_mmx.c:94: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
enc/x86_32/dct_decode_mmx.c:96: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
enc/x86_32/dct_decode_mmx.c:94: error: 'asm' operand has impossible constraints
enc/x86_32/dct_decode_mmx.c:96: error: 'asm' operand has impossible constraints
make[2]: *** [libtheora_la-dct_decode_mmx.lo] Error 1

With -fomit-frame-pointer everything is fine.

My CFLAGS: "-O2 -march=prescott -mtune=generic -pipe".
