X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eb7a7903b3d52025762a486b3e38b76630fe276a;p=gcc.git

sparc.c (load_pic_register): Emit the appropriate variant of the load_pcrel_sym pattern.

	* config/sparc/sparc.c (load_pic_register): Emit the appropriate
	variant of the load_pcrel_sym pattern.
	* config/sparc/sparc.md (P macro): Move to the top.
	(load_pcrel_sym): Macroize using P.
	(save_register_window): Likewise.
