Hello, I asked a question on Stack Overflow (http://stackoverflow.com/questions/10964893/q-in-inline-assembly-with-arch-i386) a couple days ago, but thought I would ask here in case someone can help me out. My question has to do with the use of the 'q' modifier to %1 on line 110 of pulsecore/svolume_mmx.c (of PulseAudio release 1.1) In particular, I'm trying to link PulseAudio to a 32-bit application on my 64-bit mac. When I compile this file with the "-arch i386" flag, the asm code generator fills in "%q1" to %rcx, which is a 64-bit register. The assembler then can't assemble the file in 32-bit mode. Using any combination of "-arch i386", "-m32" and "-march i386" doesn't help.
