Pinned topic Specific xlc_r compiler options used at each optimization level

‏2012-03-21T01:19:17Z |
I'm trying to track down some problematic behavior that occurs using xlc_r on AIX 5.3. The problem occurs with -O2 level optimization, but not with -O0. I have searched the web and this forum for anything that describes the individual optimizations associated with -O2, but have come up empty so far. This info is available on the web for the Sun C compiler we use. If anyone knows
of such info for xlc_r, or a good place to look, please let me know.
