Fangrui Song	789a46f2d7	[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition ... Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.

Eric Christopher	758aad76d8	Remove the -faltivec alias option and replace it with -maltivec everywhere. ... The alias was only ever used on darwin and had some issues there, and isn't used in practice much. Also fixes a problem with -mno-altivec not turning off -maltivec. Also add a diagnostic for faltivec/fno-altivec that directs users to use maltivec options and include the altivec.h file explicitly. llvm-svn: 298449	2017-03-21 22:06:18 +00:00
Alp Toker	f082e73696	Remove some incorrect test suppressions ... These don't actually require any registered backend to run. This commit tests the water with a handful of fixes for what is a more widespread problem. llvm-svn: 212008	2014-06-30 01:34:09 +00:00
NAKAMURA Takumi	7cbe30fc43	clang/test: REQUIRES: s/ppc{32|64}-registered-target/powerpc-registered-target/ ... llvm-svn: 196349	2013-12-04 03:41:15 +00:00
Jim Grosbach	2987c57924	Tests: check for target availability for target-specific tests. ... Lots of tests are using an explicit target triple w/o first checking that the target is actually available. Add a REQUIRES clause to a bunch of them. This should hopefully unbreak bots which don't configure w/ all targets enabled. llvm-svn: 159949	2012-07-09 18:34:21 +00:00
Eli Friedman	803acb3ff2	Add support for bitcasts to vector type in Evaluate. ... llvm-svn: 147137	2011-12-22 03:51:45 +00:00
Richard Smith	161f09abd7	Move vector bitcast handling in constant expressions from the expression ... evaluator into constant initializer handling / IRGen. The practical consequence of this is that the bitcast now lives in the constant's definition, rather than in its uses. The code in the constant expression evaluator was producing vectors of the wrong type and size (and possibly of the wrong value for a big-endian int-to-vector bitcast). We were getting away with this only because we don't yet support constant-folding of any expressions which inspect vector values. llvm-svn: 145981	2011-12-06 22:44:34 +00:00
Eli Friedman	409943efcb	Don't emit nsw flags for vector operations; there's basically no benefit, and a lot of downside (like PR9850, which is about clang's xmmintrin.h making an unexpected transformation on an expression involving _mm_add_epi32). ... llvm-svn: 131000	2011-05-06 18:04:18 +00:00
Anton Yartsev	28ccef788b	supported: AltiVec vector initialization with a single literal according to PIM section 2.5.1 - after initialization all elements have the value specified by the literal ... llvm-svn: 128375	2011-03-27 09:32:40 +00:00
John McCall	875679eea0	Fix the constant evaluator for AltiVec-style vector literals so that the ... vector is filled with the given constant; we were just initializing the first element. llvm-svn: 105824	2010-06-11 17:54:15 +00:00
