yaxunl added a comment. Would you please add the following lit test
F12245277: diff.pch.txt <https://reviews.llvm.org/F12245277> If you change FastMath, FiniteMathOnly and UnsafeFPMath to COMPATIBLE_LANGOPT, the test should pass. ================ Comment at: clang/include/clang/Basic/LangOptions.def:192 COMPATIBLE_LANGOPT(Deprecated , 1, 0, "__DEPRECATED predefined macro") -COMPATIBLE_LANGOPT(FastMath , 1, 0, "fast FP math optimizations, and __FAST_MATH__ predefined macro") -COMPATIBLE_LANGOPT(FiniteMathOnly , 1, 0, "__FINITE_MATH_ONLY__ predefined macro") -COMPATIBLE_LANGOPT(UnsafeFPMath , 1, 0, "Unsafe Floating Point Math") -COMPATIBLE_LANGOPT(AllowFPReassoc , 1, 0, "Permit Floating Point reassociation") -COMPATIBLE_LANGOPT(NoHonorNaNs , 1, 0, "Permit Floating Point optimization without regard to NaN") -COMPATIBLE_LANGOPT(NoHonorInfs , 1, 0, "Permit Floating Point optimization without regard to infinities") -COMPATIBLE_LANGOPT(NoSignedZero , 1, 0, "Permit Floating Point optimization without regard to signed zeros") -COMPATIBLE_LANGOPT(AllowRecip , 1, 0, "Permit Floating Point reciprocal") -COMPATIBLE_LANGOPT(ApproxFunc , 1, 0, "Permit Floating Point approximation") +BENIGN_LANGOPT(FastMath , 1, 0, "fast FP math optimizations, and __FAST_MATH__ predefined macro") +BENIGN_LANGOPT(FiniteMathOnly , 1, 0, "__FINITE_MATH_ONLY__ predefined macro") ---------------- mibintc wrote: > Here's another problem, I added the test case from bug 46166 @yaxunl but that > test case reports incompatibility because the pch is compiled with different > settings than where it is used.

This allows users to use -fno-validate-pch to relax the check on them. This is the old behavior and I do not see a reason to change that.
