I found the ChangeLog for this patch from our old files.
2008-02-11 David Ung <davidu@mips.com>
* config/mips/mips.c (mips_output_division): When
GENERATE_DIVIDE_TRAPS, generate the trap instructions against
zero
before the actual divide. This is friendlier to out-of-order
cpus
like the 74k.
Thanks!
