fixed a few bugs that revealed. Now the "register read" command should show AVX registers (ymm0-ymm15) on Mac OS X platforms that support them. When testing this on Mac OS X, run debugserver manually, like this: debugserver --native-regs localhost:1111 /path/to/executable Then lldb /path/to/executable ... (lldb) process connect connect://localhost:1111 llvm-svn: 135331
