Kenneth Uildriks	e711736014	Make opt default to not adding a target data string and update tests that depend on target data to supply it within the test ... llvm-svn: 85900	2009-11-03 15:29:06 +00:00
Dan Gohman	205b641954	Change tests from "opt %s" to "opt < %s" so that opt doesn't see the ... input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537	2009-09-11 18:01:28 +00:00
Dan Gohman	c95df8b6d8	Use opt -S instead of piping bitcode output through llvm-dis. ... llvm-svn: 81257	2009-09-08 22:34:10 +00:00
Dan Gohman	8d84372836	Change these tests to feed the assembly files to opt directly, instead ... of using llvm-as, now that opt supports this. llvm-svn: 81226	2009-09-08 16:50:01 +00:00
Dan Gohman	3d93bc5654	Change these tests to use regular loads instead of llvm.x86.sse2.loadu.dq. ... Enhance instcombine to use the preferred field of GetOrEnforceKnownAlignment in more cases, so that regular IR operations are optimized in the same way that the intrinsics currently are. llvm-svn: 64623	2009-02-16 00:44:23 +00:00
Chris Lattner	cab9f1e32b	oops, forgot to commit this. ... llvm-svn: 41034	2007-08-12 16:55:14 +00:00
Chris Lattner	3548932573	when we see a unaligned load from an insufficiently aligned global or ... alloca, increase the alignment of the load, turning it into an aligned load. This allows us to compile: #include <xmmintrin.h> __m128i foo(__m128i x){ static const unsigned int c_0[4] = { 0, 0, 0, 0 }; __m128i v_Zero = _mm_loadu_si128((__m128i*)c_0); x = _mm_unpacklo_epi8(x, v_Zero); return x; } into: _foo: punpcklbw _c_0.5944, %xmm0 ret .data .lcomm _c_0.5944,16,4 # c_0.5944 instead of: _foo: movdqu _c_0.5944, %xmm1 punpcklbw %xmm1, %xmm0 ret .data .lcomm _c_0.5944,16,2 # c_0.5944 llvm-svn: 40971	2007-08-09 19:05:49 +00:00
