RFC: http://lists.llvm.org/pipermail/cfe-dev/2020-May/065430.html Agreement from GCC: https://sourceware.org/pipermail/gcc-patches/2020-May/545688.html g_flags_Group options generally don't affect the amount of debugging information. -gsplit-dwarf is an exception. Its order dependency with other gN_Group options make it inconvenient in a build system: * -g0 -gsplit-dwarf -> level 2 -gsplit-dwarf "upgrades" the amount of debugging information despite the previous intention (-g0) to drop debugging information * -g1 -gsplit-dwarf -> level 2 -gsplit-dwarf "upgrades" the amount of debugging information. * If we have a higher-level -gN, -gN -gsplit-dwarf will supposedly decrease the amount of debugging information. This happens with GCC -g3. The non-orthogonality has confused many users. GCC 11 will change the semantics (-gsplit-dwarf no longer implies -g2) despite the backwards compatibility break. This patch matches its behavior. New semantics: * If there is a g_Group, allow split DWARF if useful (none of: -g0, -gline-directives-only, -g1 -fno-split-dwarf-inlining) * Otherwise, no-op. To restore the original behavior, replace -gsplit-dwarf with -gsplit-dwarf -g. Reviewed By: dblaikie Differential Revision: https://reviews.llvm.org/D80391 |
