Subject: [60/67] Pass scalar_int_modes to do_jump_by_parts_*
Date: Fri, 09 Dec 2016 13:36:00 -0000 [thread overview]
Message-ID: <87a8c5fcmm.fsf@e105548-lin.cambridge.arm.com> (raw)
In-Reply-To: <87h96dp8u6.fsf@e105548-lin.cambridge.arm.com> (Richard Sandiford's message of "Fri, 09 Dec 2016 12:48:01 +0000")
The callers of do_jump_by_parts_* had already established
that the modes were MODE_INTs, so this patch passes the
modes down as scalar_int_modes.

David Sherwood <david.sherwood@arm.com>
* dojump.c (do_jump_by_parts_greater_rtx): Change the type of
the mode argument to scalar_int_mode.
(do_jump_by_parts_zero_rtx): Likewise.
(do_jump_by_parts_equality_rtx): Likewise.
(do_jump_by_parts_greater): Take a mode argument.
(do_jump_by_parts_equality): Likewise.
(do_jump_1): Update calls accordingly.
