Oops, this code has a bug on x86_64 and i386: It may leave the exception
traps masked, due to a side effect of the 'fnsetenv' instruction. This
patch should fix it.
2023-10-30 Bruno Haible <bruno@clisp.org>
fenv-exceptions-tracking-{c99,c23}: Fix the x86_64 and i386 case.
* lib/fenv-except-tracking-clear.c (feclearexcept): Make sure to restore
the exception trap bits in all cases.
* lib/fenv-except-tracking-raise.c (feraiseexcept): Likewise.
* lib/fenv-except-tracking-set.c (fesetexcept): Likewise.
