Subject: Use move-aware auto_vec in map
X-Git-Tag: basepoints/gcc-16~7843
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=86451e10f6e3bad0c719a9e30f1d9dea36819025;p=thirdparty%2Fgcc.git

Use move-aware auto_vec in map

Using auto_vec rather than vec for means the vectors are release
automatically upon return, to stop the leak. The problem seems is that
auto_vec<T, N> is not really move-aware, only the <T, 0> specialization
is.

gcc/ChangeLog:

	* tree-profile.cc (find_conditions): Use auto_vec without
	embedded storage.
