[Lldb-commits] [PATCH] First cut of PowerPC(64) support in LLDB.

[Justin Hibbits]

Hi zturner, emaste, tfiala,

This adds preliminary support for PowerPC/PowerPC64, for FreeBSD.  There are
some issues still:

 * Breakpoints don't work well on powerpc64.
 * Shared libraries don't yet get loaded for a 32-bit process on powerpc64 host.
 * Backtraces don't work.  This is due to PowerPC ABI using a backchain pointer
   in memory, instead of a dedicated frame pointer register for the backchain.
 * Breakpoints on functions without debug info may not work correctly for 32-bit
   powerpc.
