C++20 coroutines introduces a new operator with a mangling of 'aw'. This patch adds that to libiberty's demangler. libiberty/ChangeLog: 2020-01-18 Iain Sandoe * cp-demangle.c (cplus_demangle_operators): Add the co_await operator. * testsuite/demangle-expected: Test co_await operator mangling. --- libiberty/cp-demangle.c | 1 + libiberty/testsuite/demangle-expected | 3 +++ 2 files changed, 4 insertions(+) diff --git a/libiberty/cp-demangle.c b/libiberty/cp-demangle.c index 3639bfbfd43..fc55b7fae1f 100644 --- a/libiberty/cp-demangle.c +++ b/libiberty/cp-demangle.c @@ -1802,6 +1802,7 @@ const struct demangle_operator_info cplus_demangle_operators[] = { "ad", NL ("&"), 1 }, { "an", NL ("&"), 2 }, { "at", NL ("alignof "), 1 }, + { "aw", NL ("co_await "), 1 }, { "az", NL ("alignof "), 1 }, { "cc", NL ("const_cast"), 2 }, { "cl", NL ("()"), 2 }, diff --git a/libiberty/testsuite/demangle-expected b/libiberty/testsuite/demangle-expected index 5878d96dee3..daffe782112 100644 --- a/libiberty/testsuite/demangle-expected +++ b/libiberty/testsuite/demangle-expected @@ -1450,3 +1450,6 @@ Foo()::{lambda(auto:1)#1}::operator()(char) const::X::fn _Z3fooILPv0EEvPN9enable_ifIXeqT_LDnEEvE4typeE void foo<(void*)0>(enable_if<((void*)0)==((decltype(nullptr))), void>::type*) + +_ZNK5coro15emptyawEv +coro1::empty::operator co_await() const -- 2.30.2
