Wang, Pengfei	3239b5034e	[FPEnv] Add pragma FP_CONTRACT support under strict FP. ... Summary: Support pragma FP_CONTRACT under strict FP.

Ulrich Weigand	1e89188d35	[FPEnv] Remove unnecessary rounding mode argument for constrained intrinsics ... The following intrinsics currently carry a rounding mode metadata argument: llvm.experimental.constrained.minnum llvm.experimental.constrained.maxnum llvm.experimental.constrained.ceil llvm.experimental.constrained.floor llvm.experimental.constrained.round llvm.experimental.constrained.trunc This is not useful since the semantics of those intrinsics do not in any way depend on the rounding mode. In similar cases, other constrained intrinsics do not have the rounding mode argument. Remove it here as well.

Kevin P. Neal	6515c524b0	[FPEnv] clang support for constrained FP builtins ... Change the IRBuilder and clang so that constrained FP intrinsics will be emitted for builtins when appropriate. Only non-target-specific builtins are affected in this patch. Differential Revision: https://reviews.llvm.org/D70256	2019-12-10 13:09:12 -05:00
