X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d1e3e3ec02342fb0b26295df7d20569c27c9a94e;p=thirdparty%2Fgcc.git

gccrs: Avoid copy when constructing TypeBoundPredicate

Construct the TypeBoundPredicate in the vector instead of copying it.

gcc/rust/ChangeLog:

	* typecheck/rust-hir-trait-resolve.cc (TraitResolver::resolve_trait):
	Construct value in place.
