Subject: i386.md (bswap<mode>2): Macroize expander from bswap{si,di}2 using SWI48 mode iterator.
X-Git-Tag: releases/gcc-4.6.0~7747
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2d2d5a918acab15f113b4efaa0afd339cbbd4053;p=thirdparty%2Fgcc.git

i386.md (bswap<mode>2): Macroize expander from bswap{si,di}2 using SWI48 mode iterator.

	* config/i386/i386.md (bswap<mode>2): Macroize expander from
	bswap{si,di}2 using SWI48 mode iterator.
	(*bswap<mode>2_movbe): Macroize insn from *bswap{si,di}_movbe using
	SWI48 mode iterator.  Set type attribute of bswap insn to bitmanip,
	set modrm attribute of bswap insn to 0 and remove length attribute.
	(*bswap<mode>2_1): Macroize insn from *bswap{si,di}_1 using SWI48 mode
	iterator.  Set type attribute to bitmanip, set modrm attribute to 0,
	set mode attribute to <MODE> and remove length attribute.
