Sorry, pointed to the incorrect patch, it should be http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=201858 These symbols will not be emitted in the symbol table in assembly, but they will be emitted in the debug_info after http://gcc.gnu.org/viewcvs/gcc?view=revision&revision=201858, which emits function's linkage name in debug_info even when it's abstract. The *INTERNAL* assertion I removed is an over-assertion that not only assert for symbol table, but also for debug info. Thanks, Dehao > > Jason >
