standards on SIGFPE for divide by zero?
I'm currently slogging through various tests which are failing on
macppc, and I came across the two that involve SIGFPE being thrown when
detecting integer and floating point divide-by-zero. NetBSD/macppc
(and, I assume, all the NetBSD powerpc ports) don't signal on
divide-by-zero, and so these tests fail.
(/usr/src/tests/lib/libc/gen/t_siginfo.c is the source file: the
sigfpe_flt and sigfpe_int tests, respectively)
My question is: what do the relevant standards say about this? Is it
required to SIGFPE? If it's required, I'll file a PR against
port-powerpc and mark the tests expected-fail on ppc. If not, then I'll
skip them on ppc.
