After emerging jack-audio-connection-kit-0.99.0 jackd fails with an illegal instruction: I noticed that during the build, the -msse and -mfpmath-sse options ar included in much of the output, and I suspect that this is the source of the problem, though am not sure. Furthermore, --march=i686 is included, which it definitely should not be given that I am on an athlon.

Same problem here. May be we shouldn't use --enable-optimize and set sse and mmx manually: # myconf="${myconf} --enable-optimize --with-gnu-ld" myconf="${myconf} `use_enable sse` `use_enable mmx` --with-gnu-ld" Dirk

Uhm... your processor supports sse and mms. I'm more concerned with your CFLAGS... Try this: CFLAGS="-O2 -march=athlon -pipe" Then slowly raise until it breaks.
I'm pretty sure Dirk's Athlon doesn't support SSE, though it does do MMX. I have exactly the same problem he does on my Duron system. Jackd works when I use his modified ebuild. Here's my cpuinfo: processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 3 model name : AMD Duron(tm) Processor stepping : 1 cpu MHz : 801.784 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow bogomips : 1585.15
this is fixed in -r1, thanks... I thought all athlon's supported sse... oh well =)
