From 32093a1c28250bc08a8b69d63aa91c358f7d42fb Mon Sep 17 00:00:00 2001 From: Adam Nemet Date: Wed, 29 Mar 2017 20:39:49 +0000 Subject: Use FPContractModeKind universally FPContractModeKind is the codegen option flag which is already ternary (off, on, fast). This makes it universally the type for the contractable info across the front-end: * In FPOptions (i.e. in the Sema + in the expression nodes). * In LangOpts::DefaultFPContractMode which is the option that initializes FPOptions in the Sema. Another way to look at this change is that before fp-contractable on/off were the only states handled to the front-end: * For "on", FMA folding was performed by the front-end * For "fast", we simply forwarded the flag to TargetOptions to handle it in LLVM Now off/on/fast are all exposed because for fast we will generate fast-math-flags during CodeGen. This is toward moving fp-contraction=fast from an LLVM TargetOption to a FastMathFlag in order to fix PR25721.
