2023-03-10	Revert "Currently the control of the eval-method is mixed with fast-math."	Zahira Ammarguellat
	Setting __FLT_EVAL_METHOD__ to -1 with fast-math will set __GLIBC_FLT_EVAL_METHOD to 2 and long double ends up being used for float_t and double_t. This creates some ABI breakage with various C libraries. See details here: https://github.com/llvm/llvm-project/issues/60781 This reverts commit bbf0d1932a3c1be970ed8a580e51edf571b80fd5.
2022-06-29	[Clang][Preprocessor] Fix inconsistent `FLT_EVAL_METHOD` when compiling vs ↵	Egor Zhdan
	preprocessing When running `clang -E -Ofast` on macOS, the `__FLT_EVAL_METHOD__` macro is `0`, which causes the following typedef to be emitted into the preprocessed source: `typedef float float_t`. However, when running `clang -c -Ofast`, `__FLT_EVAL_METHOD__` is `-1`, and `typedef long double float_t` is emitted. This causes build errors for certain projects, which are not reproducible when compiling from preprocessed source. The issue is that `__FLT_EVAL_METHOD__` is configured in `Sema::Sema` which is not executed when running in `-E` mode. This change moves that logic into the preprocessor initialization method, which is invoked correctly in `-E` mode. rdar://96134605 rdar://92748429 Differential Revision: https://reviews.llvm.org/D128814

2022-02-18	Revert "Add support for floating-point option `ffp-eval-method` and for"	Florian Hahn
	This reverts commit 32b73bc6ab8234b670c34d5ef999300e072cc706. This breaks builds on macOS in some configurations, because __FLT_EVAL_METHOD__ is set to an unexpected value.
