Richard Smith ebf6fd633e Make OpenMP tests less brittle in the face of changes in constant 
evaluation diagnostics.
 2020-10-05 19:04:14 -07:00
Richard Smith 6f33936719 Explain why the array bound is non-constant in VLA diagnostics. 
In passing, also use a more precise diagnostic to explain why an
expression is not an ICE if it's not of integral type.

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.
