This patch implements proposal https://lists.llvm.org/pipermail/llvm-dev/2020-August/144579.html llvm-dwarfutil - is a tool that is used for processing debug info(DWARF) located in built binary files to improve debug info quality, reduce debug info size. The patch currently implements smaller set of command-line options(comparing to the proposal): ``` ./llvm-dwarfutil [options] <input file> <output file> --garbage-collection Do garbage collection for debug info(default) -j <value> Alias for --num-threads --no-garbage-collection Don`t do garbage collection for debug info --no-odr-deduplication Don`t do ODR deduplication for debug types --no-odr Alias for --no-odr-deduplication --no-separate-debug-file Create single output file, containing debug tables(default) --num-threads <threads> Number of available threads for multi-threaded execution. Defaults to the number of cores on the current machine --odr-deduplication Do ODR deduplication for debug types(default) --odr Alias for --odr-deduplication --separate-debug-file Create two output files: file w/o debug tables and file with debug tables --tombstone [bfd,maxpc,exec,universal] Tombstone value used as a marker of invalid address(default: universal) =bfd - Zero for all addresses and [1,1] for DWARF v4 (or less) address ranges and exec =maxpc - Minus 1 for all addresses and minus 2 for DWARF v4 (or less) address ranges =exec - Match with address ranges of executable sections =universal - Both: bfd and maxpc ``` Reviewed By: clayborg Differential Revision: https://reviews.llvm.org/D86539
