Subject: Allocate non_null_ref tables at creation.
X-Git-Tag: basepoints/gcc-13~4556
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=08f392534a2c65fcebb1ce5a2f04459ac993a2f0;p=thirdparty%2Fgcc.git

Allocate non_null_ref tables at creation.

Preallocating the space is slightly cheaper than calling
safe_grow_cleared.

gcc/ChangeLog:

	* gimple-range-cache.cc (non_null_ref::non_null_ref): Use create
	and quick_grow_cleared instead of safe_grow_cleared.
