Subject: Add noexcept to custom non-throwing new operators.
X-Git-Tag: users/ARM/embedded-binutils-master-2016q4~123
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bbe910e6e1140cb484a74911f3cea854cf9e7e2a;p=external%2Fbinutils.git

Add noexcept to custom non-throwing new operators.

Both libc++ and libstdc++ declare non-throwing new operators as
noexcept and overloads must also be noexcept.  This fixes a
-Wmissing-exception-spec warning with clang.

gdb/ChangeLog:

	* common/new-op.c (operator new): Mark 'noexcept'.
	(operator new[]): Likewise.
