Manman Ren	1a5ff287fd	TBAA: remove !tbaa from testing cases if not used. ... This will make it easier to turn on struct-path aware TBAA since the metadata format will change. llvm-svn: 180796	2013-04-30 17:52:57 +00:00
Hal Finkel	8d7fbc9dad	Enable unaligned memory access on PPC for scalar types ... Unaligned access is supported on PPC for non-vector types, and is generally more efficient than manually expanding the loads and stores. A few of the existing test cases were using expanded unaligned loads and stores to test other features (like load/store with update), and for these test cases, unaligned access remains disabled. llvm-svn: 177160	2013-03-15 15:27:13 +00:00
Nadav Rotem	70409991bc	During the CodeGenPrepare we often lower intrinsics (such as objsize) ... and allow some optimizations to turn conditional branches into unconditional. This commit adds a simple control-flow optimization which merges two consecutive basic blocks which are connected by a single edge. This allows the codegen to operate on larger basic blocks. rdar://11973998 llvm-svn: 161852	2012-08-14 05:19:07 +00:00
Hal Finkel	ca542beffe	Add support for generating reg+reg (indexed) pre-inc loads on PPC. ... llvm-svn: 158823	2012-06-20 15:43:03 +00:00
