Chris Lattner 3b0a62d8a5 Implement a little hack for parity with GCC on crafty. This speeds up ... 186.crafty by about 16% (from 15.109s to 13.045s) on my system. This turns allocas with unions/casts into scalars. For example crafty has something like this: union doub { unsigned short i[4]; long long d; }; int f(long long a) { return ((union doub){.d=a}).i[1]; } Instead of generating loads and stores to an alloca, we now promote the whole thing to a scalar long value. This implements: Transforms/ScalarRepl/AggregatePromote.ll llvm-svn: 24667		2005-12-12 07:19:13 +00:00
