Joel E. Denny	3234887fe2	[APSInt][OpenMP] Fix isNegative, etc. for unsigned types ... Without this patch, APSInt inherits APInt::isNegative, which merely checks the sign bit without regard to whether the type is actually signed. isNonNegative and isStrictlyPositive call isNegative and so are also affected. This patch adjusts APSInt to override isNegative, isNonNegative, and isStrictlyPositive with implementations that consider whether the type is signed. A large set of Clang OpenMP tests are affected. Without this patch, these tests assume that `true` is not a valid argument for clauses like `collapse`. Indeed, `true` fails APInt::isStrictlyPositive but not APSInt::isStrictlyPositive. This patch adjusts those tests to assume `true` should be accepted. This patch also adds tests revealing various other similar fixes due to APSInt::isNegative calls in Clang's ExprConstant.cpp and SemaExpr.cpp: `++` and `--` overflow in `constexpr`, evaluated object size based on `alloc_size`, `<<` and `>>` shift count validation, and OpenMP array section validation.

Alexey Bataev	a8a9153a37	[OPENMP] Support for -fopenmp-simd option with compilation of simd loops ... only. Added support for -fopenmp-simd option that allows compilation of simd-based constructs without emission of OpenMP runtime calls. llvm-svn: 321560	2017-12-29 18:07:07 +00:00
Charles Li	bbf78cda2a	Lit C++11 Compatibility Patch #6 ... Updated the expected diagnostics of 17 OpenMP tests. The changes to each test are identical. llvm-svn: 265982	2016-04-11 19:30:25 +00:00
Alexey Bataev	a056935a2f	[OPENMP 4.5] Parsing/sema analysis for 'priority' clause. ... OpenMP 4.5 defines new clause 'priority' for 'task', 'taskloop' and 'taskloop simd' directives. Added parsing and sema analysis for 'priority' clause in 'task' and 'taskloop' directives. llvm-svn: 254398	2015-12-01 10:17:31 +00:00
Alexey Bataev	db39021cee	[OPENMP] -fopenmp enables OpenMP support (fix for http://llvm.org/PR23492) ... -fopenmp turns on OpenMP support and links libiomp5 as OpenMP library. Also there is -fopenmp={libiomp5|libgomp} option that allows to override effect of -fopenmp and link libgomp library (if -fopenmp=libgomp is specified).
