The e500 SPE floating-point emulation code is called from
SPEFloatingPointException and SPEFloatingPointRoundException in
arch/powerpc/kernel/traps.c. Those functions have support for
generating SIGFPE, but do_spe_mathemu and speround_handler don't
generate a return value to indicate that this should be done. Such a
return value should depend on whether an exception is raised that has
been set via prctl to generate SIGFPE. This patch adds the relevant
logic in these functions so that SIGFPE is generated as expected by
the glibc testsuite.
