Bug ID: 97263
Summary: For -ffinite-math-only -OFast is not mentioned.
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: web
Assignee: unassigned at gcc dot gnu.org
Reporter: olaf.krzikalla at dlr dot de
Target Milestone: ---
The description of -ffinite-math-only at
https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
reads:
"This option is not turned on by any -O option since..."
This is not true for -Ofast. Hence it should read:
"This option is not turned on by any -O option beside -Ofast since..."
See also the description of -ffast-math.

I will modify the documentation next week to be more specific on this since
-Ofast is a hot topic right now including in LLVM.
e.g. https://discourse.llvm.org/t/rfc-deprecate-ofast/78687/36

I noticed a few other options have a similar wording that was incorrect since
-Ofast was added so I fixed them too.

The trunk branch has been updated by Andrew Pinski <pinskia@gcc.gnu.org>:
https://gcc.gnu.org/g:0920e64ffa55adb063174559b274b0a521f34934
commit r15-237-g0920e64ffa55adb063174559b274b0a521f34934
Author: Andrew Pinski <quic_apinski@quicinc.com>
Date: Mon May 6 14:14:41 2024 -0700
Mention that some options are turned on by `-Ofast` in their descriptions
[PR97263]
Like was done for -ffast-math in r0-105946-ga570fc16fa8056, we should
document that -Ofast enables -fmath-errno, -funsafe-math-optimizations,
-finite-math-only, -fno-trapping-math in their documentation.
Note this changes the stronger "must not" to be "is not" for
-fno-trapping-math
since we do enable it for -Ofast already.
gcc/ChangeLog:
PR middle-end/97263
* doc/invoke.texi(fmath-errno): Document it is turned on
with -Ofast.
(funsafe-math-optimizations): Likewise.
(ffinite-math-only): Likewise.
(fno-trapping-math): Likewise and use less strong language.
