X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3edaf26de0dd7a7475646809d1e2841be665a59c;p=gcc.git

[AArch64] Use selected cpu's tuning when no tuning parameter is specified

gcc/

2014-12-05  Renlin Li  <renlin.li@arm.com>

	* config/aarch64/aarch64.c (aarch64_parse_cpu): Don't define
	selected_tune.
	(aarch64_override_options): Use selected_cpu's tuning.
