--- Comment #4 from Dmitry G. Dyachenko <dimhen at gmail dot com> --- (In reply to Dominique d'Humieres from comment #2) > Are you sure that r212549 fails? I'ld rather suspect a typo in r212550, > i.e., DECL_ARGUMENT instead of DECL_ARGUMENT_FLD. Sorry, err in err.message. Correct error message for r212549 /home/dimhen/src/gcc_r212549/gcc/fold-const.c: In function 'void fold_checksum_tree(const_tree, md5_ctx*, hash_table<pointer_hash<const tree_node> >*)': /home/dimhen/src/gcc_r212549/gcc/fold-const.c:14865:47: error: 'DECL_ARGUMENT_FLD' was not declared in this scope fold_checksum_tree (DECL_ARGUMENT_FLD (expr), ctx, ht); ^
