--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
I also see this on 32-bit Solaris/SPARC.  There are testresult reports for a
couple of other targets, too.  This seems to be at -O3 -fomit-frame-pointer
only,
not plain -O3.

GCC 14.1 is being released, retargeting bugs to GCC 14.2.

--- Comment #3 from Rainer Orth <ro at gcc dot gnu.org> ---
FWIW, I've now found that on sparc-sun-solaris2.11 (32-bit only) the warning
occurs as far back as gcc 10 with just

gcc -O3 -ftracer

Back in gcc 10, it would happen for both -m32 and -m64, while from gcc 11
onward, it's for -m32 only.
