Package: g++-15
Version: 15.2.0-2
Severity: normal
Dear Maintainer,
std::format emits a warning when compiling with -O2 -march=broadwell:
$ cat warn.cc
#include <format>
int main() {
(void)std::format("{}", 3.14152);
}
$ g++ -std=c++20 -O2 -march=broadwell warn.cc -c
/tmp/ccPn7jw8.s: Assembler messages:
/tmp/ccPn7jw8.s: Warning: no SFrame FDE emitted; non-SP/FP register 10 in
.cfi_def_cfa
$ g++ -std=c++20 -O3 -march=broadwell warn.cc -c
/tmp/ccXYo09Q.s: Assembler messages:

.cfi_def_cfa
/tmp/ccXYo09Q.s: Warning: no SFrame FDE emitted; non-SP/FP register 10 in

As far as i can see this does not impact either the program nor
compiling with -Werror enabled, but I have no idea what's going on and
if this is harmless indeed.
Thanks
Ingo
