That's what I first implemented, and I still firmly believe symtab_get_node is the correct test. TREE_ASM_WRITTEN doesn't carry the same information as far as external objects are concerned, so we ended up failing to register them when I tried it, and that caused regressions in the testsuite, with tests that were designed to catch precisely this sort of error. -- Alexandre Oliva, freedom fighter http://FSFLA.org/~lxoliva/ You must be the change you wish to see in the world. -- Gandhi Be Free! -- http://FSFLA.org/ FSF Latin America board member Free Software Evangelist Red Hat Brazil Compiler Engineer
