Subject: sse.md (movdi_to_sse): Use gen_lowpart and gen_higpart instead of gen_rtx_SUBREG.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=112fc9c3994053942c51b1bf4c58e51f26cf9f90;p=gcc.git

sse.md (movdi_to_sse): Use gen_lowpart and gen_higpart instead of gen_rtx_SUBREG.

	* config/i386/sse.md (movdi_to_sse): Use gen_lowpart
	and gen_higpart instead of gen_rtx_SUBREG.
	* config/i386/i386.md
	(floatdi<X87MODEF:mode>2_i387_with_xmm splitter): Ditto.
	(read-modify peephole2): Use gen_lowpart instead of
	gen_rtx_SUBREG for operand 5.
