- Fix -fno-unsafe-math-optimizations behavior - [WIP] Major change to fast-math.c lit test - Clean up the checks in the fast-math driver test >From 100fc9dfb2b071877d758ce71bddeec693d986da Mon Sep 17 00:00:00 2001 From: Andy Kaylor <andrew.kay...@intel.com> Date: Fri, 19 Apr 2024 16:35:00 -0700 Subject: [PATCH 1/3] Fix -fno-unsafe-math-optimizations behavior This changes the handling of -fno-unsafe-fp-math to stop having that option imply -ftrapping-math. In gcc, -fno-unsafe-math-optimizations sets -ftrapping-math, but that dependency is based on the fact the -ftrapping-math is enabled by default in gcc. Because clang does not enabled -ftrapping-math by default, there is no reason for -fno-unsafe-math-optimizations to set it. On the other hand, -funsafe-math-optimizations continues to imply -fno-trapping-math because this option necessarily disables strict exception semantics.

of the cc1 option checks in the driver test for fast-math option handling. These changes rely on the assumption that the order in which the driver emits floating-point options is stable. The changes also rely on the assumption that the order of prefixes listed on the FileCheck command line is unimportant and that all prefixed checks will be combined and checked as if they were a single prefix. At the time of the change, that worked. --- clang/test/Driver/fast-math.c | 342 ++++++++++++++++------------------ 1 file changed, 159 insertions(+), 183 deletions(-) diff --git
