I have an internal binary that is build with clang 12. The structure of relevant debug info below, with all other dies and attributes removed.: DW_TAG_compile_unit [141] ... DW_TAG_namespace [2] * () DW_AT_name [DW_FORM_strp] ( .debug_str[0xa57a80dd] = "namea") ... DW_TAG_namespace [2] * DW_AT_name [DW_FORM_strp] ( .debug_str[0x7232f811] = "nameb") .. DW_TAG_subprogram [188] * DW_AT_low_pc [DW_FORM_addr] (0x0000000000000000) DW_AT_ranges [DW_FORM_sec_offset] .. DW_AT_name [DW_FORM_strp] ( .debug_str[0x667d9d2f] = "functionName") When I do disas namea::nameb::functionName I get No type "nameb" within class or namespace "namea". If I add single quotes disas 'namea::nameb::functionName' It works. I should add this debug info after this binary has been optimized with BOLT. https://lists.llvm.org/pipermail/llvm-dev/2020-October/145902.html Pre BOLT disas namea::nameb::functionName works. Main thing bolt does is convert DW_AT_low_pc/DW_AT_high_pc into DW_AT_low_pc/DW_AT_ranges. Looking at debug information for that CU only real difference is one mentioned above. The type references all point to correct dies. In LLDB it works, but it might be doing things differently. I am trying to figure out if BOLT is somehow doing something wrong, or maybe it's triggering something in GDB. Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
