Manman Ren	0b37dd0efc	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	a5a86f0a8e	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
Hal Finkel	c1fe73fae2	Enable generating PPC pre-increment (r+imm) instructions by default. ... It seems that this no longer causes test suite failures on PPC64 (after r157159), and often gives a performance benefit, so it can be enabled by default. llvm-svn: 157911	2012-06-04 02:21:00 +00:00
Hal Finkel	9fad4cf803	Add a missing PPC 64-bit stwu pattern. ... This seems to fix the remaining compile-time failures on PPC64 when compiling with -enable-ppc-preinc. llvm-svn: 157159	2012-05-20 17:11:24 +00:00
