Remove FiniteMathOnly and use only NoHonorINFs and NoHonorNANs. (#97342)

2024-07-26T12:16:38+00:00

Currently `__FINITE_MATH_ONLY__` is set when `FiniteMathOnly`. And
`FiniteMathOnly` is set when `NoHonorInfs` && `NoHonorNans` is true. But
what happens one of the latter flags is false?
To avoid potential inconsistencies, the internal option `FiniteMathOnly`
is removed option and the macro `__FINITE_MATH_ONLY__` is set when
`NoHonorInfs` && `NoHonorNans`.

[clang][CodeGen] Ensure consistent `mustprogress` attribute emission

2023-11-11T08:43:03+00:00

Emission of `mustprogress` attribute previously occurred only within
`EmitFunctionBody`, after generating the function body. Other routines
for function body creation may lack the attribute, potentially leading
to suboptimal optimizations later in the pipeline. Attribute emission
is now anticipated prior to generating the function body.

clang: Stop emitting "strictfp"

2023-07-07T19:28:21+00:00

The attribute is a proper enum attribute, strictfp. We were getting
strictfp and "strictfp" set on every function with
-fexperimental-strict-floating-point.

[clang][patch][FPEnv] Fix syntax errors in pragma float_control test

2021-07-30T13:59:45+00:00

In a post-commit message to https://reviews.llvm.org/D102343
@MaskRay pointed out syntax errors in one of the test cases. This
patch fixes those problems, I had forgotten the colon after the CHECK- strings.

[clang][patch][FPEnv] Make initialization of C++ globals strictfp aware

2021-07-29T16:02:37+00:00

@kpn pointed out that the global variable initialization functions didn't
have the "strictfp" metadata set correctly, and @rjmccall said that there
was buggy code in SetFPModel and StartFunction, this patch is to solve
those problems. When Sema creates a FunctionDecl, it sets the
FunctionDeclBits.UsesFPIntrin to "true" if the lexical FP settings
(i.e. a combination of command line options and #pragma float_control
settings) correspond to ConstrainedFP mode. That bit is used when CodeGen
starts codegen for a llvm function, and it translates into the
"strictfp" function attribute. See bugs.llvm.org/show_bug.cgi?id=44571

[clang][patch] Solve PR49479, File scope fp pragma should propagate to functions nested in struct, and initialization expressions

2021-03-15T16:15:20+00:00

Previously, the CurFPFeatures state was set to command line settings before
semantic analysis of the nested member functions and initialization
expressions, that's not correct, it should use the pragma state which
is in effect at the lexical position.
