As a result, gprofng skiped Dwarf for all functions declared as: < 2>:<0x0000f725> DW_TAG_subprogram(46) DW_AT_linkage_name(110) "func_name" DW_AT_declaration*(60) 0x1 (1) < 1>:<0x00015acc> DW_TAG_subprogram(46) DW_AT_specification(71) 0xf725 (63269) Another problem was that gprofng ignored DW_AT_ranges. As a result, many functions are mapped to the <Unknown> module. gprofng/ChangeLog 2025-05-01 Vladimir Mezentsev <vladimir.mezent...@oracle.com> PR 32892 * src/Dwarf.cc: Handle DW_AT_specification and DW_AT_ranges. * src/DwarfLib.cc: Likewise. * src/DwarfLib.h: Likewise. * src/Dwarf.h (get_ranges): New function. * src/Stabs.h (get_symbols): New function. * src/Stabs.cc: Move Symbol class to src/Symbol.cc. * src/Symbol.cc: New file. * src/Symbol.h: New file. * src/Makefile.am: Add Symbol.cc in build. * src/Makefile.in: Rebuild. * src/LoadObject.cc (dump_functions): Improve output for -dfunc option. -- You are receiving this mail because: You are on the CC list for the bug.
