Chris Lattner 9440db8866 Implement ArgumentPromotion/aggregate-promote.ll ... This allows pointers to aggregate objects, whose elements are only read, to be promoted and passed in by element instead of by reference. This can enable a LOT of subsequent optimizations in the caller function. It's worth pointing out that this stuff happens a LOT of C++ programs, because objects in templates are generally passed around by reference. When these templates are instantiated on small aggregate or scalar types, however, it is more efficient to pass them in by value than by reference. This transformation triggers most on C++ codes (e.g. 334 times on eon), but does happen on C codes as well. For example, on mesa it triggers 72 times, and on gcc it triggers 35 times. this is amazingly good considering that we are using 'basicaa' so far. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12202 91177308-0d34-0410-b5e6-96231b3b80d8		2004-03-08 01:04:36 +00:00
