Manman Ren	2dc50d3067	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180796 91177308-0d34-0410-b5e6-96231b3b80d8	2013-04-30 17:52:57 +00:00
Hal Finkel	2d37f7b979	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177160 91177308-0d34-0410-b5e6-96231b3b80d8	2013-03-15 15:27:13 +00:00
Nadav Rotem	3e883734fa	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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161852 91177308-0d34-0410-b5e6-96231b3b80d8	2012-08-14 05:19:07 +00:00
Hal Finkel	0fcdd8b2cc	Add support for generating reg+reg (indexed) pre-inc loads on PPC. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158823 91177308-0d34-0410-b5e6-96231b3b80d8	2012-06-20 15:43:03 +00:00
