Subject: [PATCH #3, cleanup] Remove PowerPC TARGET_UPPER_REGS_DI macro
Date: Tue, 25 Jul 2017 13:17:00 -0000	[thread overview]
Message-ID: <20170725131725.GA15369@ibm-tiger.the-meissners.org> (raw)
In-Reply-To: <20170725123446.GF13471@gate.crashing.org>

[-- Attachment #1: Type: text/plain, Size: 1155 bytes --]

This patch eliminates TARGET_UPPER_REGS_DI.  I deleted the poison attribute in
patch #1.  I will combine the ChangeLog and submit this patch and the previous
patch together if approved.

It bootstraps and has no regressions on big endian power7 and little endian
power8.  Can I install this patch on the trunk.

2017-07-25  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/rs6000.c (rs6000_option_override_internal):
	Eliminate TARGET_UPPER_REGS_DI.
	(rs6000_expand_vector_set): Likewise.
	* config/rs6000/vsx.md (vsx_set_<mode>_p9): Likewise.
	(vsx_set_v4sf_p9): Likewise.
	(vsx_set_v4sf_p9_zero): Likewise.
	(vsx_insert_extract_v4sf_p9): Likewise.
	(vsx_insert_extract_v4sf_p9_2): Likewise.
	* config/rs6000/rs6000.c (TARGET_UPPER_REGS_DI): Delete.
	(TARGET_VEXTRACTUB): Eliminate TARGET_UPPER_REGS_DI.
	(TARGET_DIRECT_MOVE_64BIT): Likewise.
	* config/rs6000/rs6000.md
	(float<QHI:mode><FP_ISA3:mode>2_internal): Likewise.
	(Splitters for DI constants in Altivec registers): Likewise.
