c++: mangle noexcept-expr [PR70790]
This implements noexcept(expr) mangling and demangling as per the
Itanium ABI.
PR c++/70790
gcc/cp/ChangeLog:
* mangle.cc (write_expression): Handle NOEXCEPT_EXPR.
libiberty/ChangeLog:
* cp-demangle.c (cplus_demangle_operators): Add the noexcept
operator.
(d_print_comp_inner) <case DEMANGLE_COMPONENT_UNARY>: Always
print parens around the operand of noexcept too.
* testsuite/demangle-expected: Test noexcept operator
demangling.
gcc/testsuite/ChangeLog:
* g++.dg/abi/mangle78.C: New test.
