Subject: [33/67] Add a NARROWEST_INT_MODE macro
Date: Fri, 09 Dec 2016 13:14:00 -0000 [thread overview]
Message-ID: <87inqtjlbx.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")
Replace uses of GET_CLASS_NARROWEST_MODE (MODE_INT) with a new
NARROWEST_INT_MODE macro, which has type scalar_int_mode.

* machmode.h (NARROWEST_INT_MODE): New macro.
* expr.c (alignment_for_piecewise_move): Use it instead of
GET_CLASS_NARROWEST_MODE (MODE_INT).
(push_block): Likewise.
* stor-layout.c (bit_field_mode_iterator::bit_field_mode_iterator):
Likewise.
* tree-vrp.c (simplify_float_conversion_using_ranges): Likewise.
