Chris Lattner 17afc211e7 Rewrite all the 'PromoteLocallyUsedAlloca[s]' logic. With the power of ... LargeBlockInfo, we can now dramatically simplify their implementation and speed them up at the same time. Now the code has time proportional to the number of uses of the alloca, not the size of the block. This also eliminates code that tried to batch up different allocas which are used in the same blocks, and eliminates the 'retry list' logic which was baroque and no unneccesary. In addition to being a speedup for crazy cases, this is also a nice cleanup: PromoteMemoryToRegister.cpp | 270 +++++++++++++++----------------------------- 1 file changed, 96 insertions(+), 174 deletions(-) llvm-svn: 58229		2008-10-27 07:05:53 +00:00
