------- Comment #3 from jakub at gcc dot gnu dot org 2010-05-24 14:38 ------- Created an attachment (id=20735) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20735&action=view) gcc46-pr42801.patch
Patch for the -O2 issue. The standard says: "Concrete inlined instance entries may omit attributes that are not specific to the concrete instance (but present in the abstract instance) and need include only attributes that are specific to the concrete instance (but omitted in the abstract instance).", which I read as not forbidding duplication of the DW_AT_type attribute (dropping DW_AT_type in the abstract instance doesn't seem to be a good idea, even when bounds aren't known the type otherwise gives useful info). Perhaps we should handle DW_TAG_formal_parameters the same way in dwarf2out.c. Unfortunately, gdb prints 0 instead of 24 in the second case. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42801
