I did some poking around with pcc -S and it looked like %%ax was only appearing in the context of the fnstsw instruction, which in pcc's source only occurs once, in line 329 of arch/i386/local2.c: expand(p, 0, "\tfnstsw %%ax\n"); My assembly is *really* basic, so I don't know what that means, but hopefully it's relevant?
