Sketch out a DWARF parser. This introduces a new library to LLVM: libDebugInfo. It will provide debug information parsing to LLVM. Much of the design and some of the code is taken from the LLDB project. It also contains an llvm-dwarfdump tool that can dump the abbrevs and DIEs from an object file. It can be used to write tests for DWARF input and output easily. llvm-svn: 139627 2011-09-13 21:42:23 +02:00			`set(LLVM_LINK_COMPONENTS`
Move DebugInfo to DebugInfo/DWARF. In preparation for adding PDB support to LLVM, this moves the DWARF parsing code to its own subdirectory under DebugInfo, and renames LLVMDebugInfo to LLVMDebugInfoDWARF. This is purely a mechanical / build system change. Differential Revision: http://reviews.llvm.org/D7269 Reviewed by: Eric Christopher llvm-svn: 227586 2015-01-30 19:07:45 +01:00			`DebugInfoDWARF`
[dwarfdump] Pretty print location expressions and location lists Summary: Based on Fred's patch here: https://reviews.llvm.org/D6771 I can't seem to commandeer the old review, so I'm creating a new one. With that change the locations exrpessions are pretty printed inline in the DIE tree. The output looks like this for debug_loc entries: DW_AT_location [DW_FORM_data4] (0x00000000 0x0000000000000001 - 0x000000000000000b: DW_OP_consts +3 0x000000000000000b - 0x0000000000000012: DW_OP_consts +7 0x0000000000000012 - 0x000000000000001b: DW_OP_reg0 RAX, DW_OP_piece 0x4 0x000000000000001b - 0x0000000000000024: DW_OP_breg5 RDI+0) And like this for debug_loc.dwo entries: DW_AT_location [DW_FORM_sec_offset] (0x00000000 Addr idx 2 (w/ length 190): DW_OP_consts +0, DW_OP_stack_value Addr idx 3 (w/ length 23): DW_OP_reg0 RAX, DW_OP_piece 0x4) Simple locations without ranges are printed inline: DW_AT_location [DW_FORM_block1] (DW_OP_reg4 RSI, DW_OP_piece 0x4, DW_OP_bit_piece 0x20 0x0) The debug_loc(.dwo) dumping in changed accordingly to factor the code.

llvm-dwarfdump: Add an option to collect debug info quality metrics. At the last LLVM dev meeting we had a debug info for optimized code BoF session. In that session I presented some graphs that showed how the quality of the debug info produced by LLVM changed over the last couple of years. This is a cleaned up version of the patch I used to collect the this data. It is implemented as an extension of llvm-dwarfdump, adding a new --statistics option. The intended use-case is to automatically run this on the debug info produced by, e.g., our bots, to identify eyebrow-raising changes or regressions introduced by new transformations that we could act on. In the current form, two kinds of data are being collected: - The number of variables that have a debug location versus the number of variables in total (this takes into account inlined instances of the same function, so if a variable is completely missing form only one instance it will be found). - The PC range covered by variable location descriptions versus the PC range of all variables' containing lexical scopes. The output format is versioned and extensible, so I'm looking forward to both bug fixes and ideas for other data that would be interesting to track.

Add llvm-dwarfdump-fuzzer that uses LibFuzzer to fuzz llvm-dwarfdump tool. The fuzzer is very simple, but not quite useful at the moment: it's unable to discover "interesting" examples, as LLVMObject library is terrible at error recovery, calling "report_fatal_error()" far too often. llvm-svn: 238451 2015-05-28 20:35:18 +02:00
cmake: Invent add_llvm_fuzzer to set up fuzzer targets This moves the cmake configuration for fuzzers in LLVM to a new macro, add_llvm_fuzzer. This will make it easier to keep things consistent while implementing llvm.org/pr34314. I've also made a couple of minor functional changes here: - the fuzzers now use add_llvm_executable rather than add_llvm_tool. This means they won't create install targets and stuff like that, because those made little sense for these fuzzers. - I've grouped these under "Fuzzers" rather than in with "Tools" for people who build with IDEs. llvm-svn: 312200 2017-08-31 02:36:33 +02:00			`add_subdirectory(fuzzer)`
