Subject: fix memory leak in optimize pragma parsing
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e4985357e5aea698cbb5620fbfccc995363c7764;p=gcc.git

fix memory leak in optimize pragma parsing

The optimize pragma/attribute parsing calls decode_cmdline_options_to_array
but doesn't free the array.  The following fixes that.

gcc/c-family/
	* c-common.c (parse_optimize_options): Free decoded_options.
