Nikita Popov	532dc62b90	[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC) ... This adds -no-opaque-pointers to clang tests whose output will change when opaque pointers are enabled by default. This is intended to be part of the migration approach described in https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9. The patch has been produced by replacing %clang_cc1 with %clang_cc1 -no-opaque-pointers for tests that fail with opaque pointers enabled. Worth noting that this doesn't cover all tests, there's a remaining ~40 tests not using %clang_cc1 that will need a followup change.

Simon Moll	0aab344104	[Clang] Allow "ext_vector_type" applied to Booleans ... This is the `ext_vector_type` alternative to D81083. This patch extends Clang to allow 'bool' as a valid vector element type (attribute ext_vector_type) in C/C++. This is intended as the canonical type for SIMD masks and facilitates clean vector intrinsic declarations. Vectors of i1 are supported on IR level and below down to many SIMD ISAs, such as AVX512, ARM SVE (fixed vector length) and the VE target (NEC SX-Aurora TSUBASA).

Erich Keane	a94f68a2bd	Implement some constexpr vector unary operators, fix boolean-ops ... As requested in the review, this implements unary +,-,~, and ! for vector types. All of our boolean operations on vector types should be using something like vcmpeqd, which results in a mask of '-1' for the 'truth' type. We are currently instead using '1', which results in some incorrect calculations when used later (note that it does NOT result in a boolean vector, as that is not really a thing). This patch corrects that 1 to be a -1, and updates the affected tests. Differential Revision: https://reviews.llvm.org/D115670	2021-12-17 06:08:36 -08:00
Erich Keane	b30c16670e	Implement constexpr BinaryOperator for vector types ... These operations do member-wise versions of the all of the listed operations. This patch implements all of the binaryoperators for these types. Note that the test is required to use codegen as I could not come up with a good way to validate the values without the array-subscript operator implemented (which is likely a much more involved change).
