Ok, so I guess this fix is not optimal as it produces more spilling
that previously.

According to lu_zero, here's what gcc-3.4 has to say:

libpostproc/postprocess_template.c:3627: error: can't find a register
in class `GENERAL_REGS' while reloading `asm'
not enough registers...
libpostproc/postprocess_template.c: In function `postProcess_MMX2':
libpostproc/postprocess_template.c:2901: warning: use of memory input
without lvalue in asm operand 4 is deprecated
libpostproc/postprocess_template.c:2901: warning: use of memory input
without lvalue in asm operand 4 is deprecated
libpostproc/postprocess_template.c:3627: error: can't find a register
in class `GENERAL_REGS' while reloading `asm'

What to do now?
