--- Comment #2 from John David Anglin <danglin at gcc dot gnu.org> ---
Currently, sysdeps/hppa/fpu/feholdexcpt.c clears the exception enable flags
for nonstop mode.  Many other architectures do the same.

It is called from libc_feholdexcept_setround in ROUND_TO_ODD.  This clears
the FE_INVALID enable set in the test.  As a result, the child isn't signaled.

Is the test valid?  It seems to me that this is likely the reason loongarch
didn't trap and set SIGFPE.
