Subject: [libiberty] Update demangler to handle co_await operator.
X-Git-Tag: upstream/12.2.0~18968
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7ebbff3acbe627c9286e2daed7751e6e6c8684e6;p=platform%2Fupstream%2Fgcc.git

[libiberty] Update demangler to handle co_await operator.

C++20 coroutines introduces a new operator with a mangling of 'aw'.
This patch adds that to libiberty's demangler.

	* cp-demangle.c (cplus_demangle_operators): Add the co_await
	operator.
	* testsuite/demangle-expected: Test co_await operator mangling.
