https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D269928 Bug ID: 269928 Summary: ctfconvert errors should be fatal Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: markj@FreeBSD.org ctfconvert has long contained a FreeBSD-specific hack to downgrade various errors into warnings. CTFv3 has eliminated much of the need for this hack,= so it should be revisited since it causes problems when cross-building FreeBSD= on MacOS and Linux. For instance, in a riscv kernel objdir: markj@nuc> readelf -S exception.o | grep -A1 debug_info [ 7] .debug_info PROGBITS 0000000000000000 00000288 0000000000000185 0000000000000000 0 0 1 [ 8] .rela.debug_info RELA 0000000000000000 00000a80 00000000000000d8 0000000000000018 I 14 7 8 markj@nuc> ctfconvert -L VERSION -g exception.o=20 ERROR: ctfconvert: failed to get offset for die: Invalid argument [dwarf_dieoffset(261)] markj@nuc> readelf -wi exception.o Dump of debug contents of section .debug_info: readelf: could not find DW_TAG_compile_unit die readelf: could not find DW_TAG_compile_unit die readelf: could not find DW_TAG_compile_unit die readelf: could not find DW_TAG_compile_unit die readelf: could not find DW_TAG_compile_unit die but binutils readelf can handle it fine, so this is some bug or missing functionality in libdwarf. Such a problem should cause a build failure. --=20 You are receiving this mail because: You are the assignee for the bug.=
