[llvm-commits] [poolalloc] r114063 - /poolalloc/trunk/lib/PoolAllocate/PASimple.cpp

[John Criswell]

New Revision: 114063

URL: http://llvm.org/viewvc/llvm-project?rev=114063&view=rev
Log:
Modifed the simple pool allocation pass so that it does not recreate the global
pool if it already exists.  This allows it to yield correct code when executed
multiple times.
Also added support for transforming stack registration.
