* [DWARF] Fix handling of extended line-number opcodesPaul Robinson2017-11-221-5/+24
| | | | | | Differential Revision: https://reviews.llvm.org/D40200 llvm-svn: 318838
* Don't #include MemoryBuffer.h from Host.h.Zachary Turner2017-11-171-0/+1
| | | | | | | | | | It turns out this #include isn't used from Host.h anyway, but by having it it causes circular include dependencies. This issues only surfaced while I was working on a separate patch, so I'm submitting this first so that it's independent of the other, unrelated patch. llvm-svn: 318489

* Revert "[DWARF] Now that Optional is standard layout, put it into an union ↵Benjamin Kramer2017-10-311-2/+2
| | | | | | | | instead of splatting it." GCC doesn't like it. This reverts commit r317028. llvm-svn: 317030
* [DWARF] Now that Optional is standard layout, put it into an union instead ↵Benjamin Kramer2017-10-311-2/+2

* Fix BB after r316756 "[llvm-dwarfdump] - Teach verifier to report broken ↵George Rimar2017-10-271-1/+1
| | | | | | | | | | | DWARF expressions." Bot: http://lab.llvm.org:8011/builders/clang-with-thin-lto-ubuntu/builds/6255 Changed format of this message by mistake. llvm-svn: 316757
* [llvm-dwarfdump] - Teach verifier to report broken DWARF expressions.George Rimar2017-10-272-29/+45
| | | | | | | | | | | | | Patch improves next things: * Fixes assert/crash in getOpDesc when giving it a invalid expression op code. * DWARFExpression::print() called DWARFExpression::Operation::getEndOffset() which returned and used uninitialized field EndOffset. Patch fixes that. * Teaches verifier to verify DW_AT_location and error out on broken expressions. Differential revision: https://reviews.llvm.org/D39294 llvm-svn: 316756
* [PDB] Handle an empty globals hash table with no bucketsReid Kleckner2017-10-271-2/+3
| | | | llvm-svn: 316722
* Re-land "[dwarfdump] Add -lookup option"Jonas Devlieghere2017-10-252-2/+30
| | | | | | | | | Add the option to lookup an address in the debug information and print out the file, function, block and line table details. Differential revision: https://reviews.llvm.org/D38409 llvm-svn: 316619
* [llvm-dwarfdump] - Fix array out of bounds access crash.George Rimar2017-10-252-0/+17
| | | | | | | | | | | This fixes possible out of bound access in DWARFDie::getFirstChild() which might happen when .debug_info section is corrupted, like shown in testcase. Differential revision: https://reviews.llvm.org/D39185 llvm-svn: 316566
* [codeview] Fix handling of S_HEAPALLOCSITEReid Kleckner2017-10-241-2/+1
| | | | | | | | | | The type index is from the TPI stream, not the IPI stream. Fix the dumper, fix type index discovery, and add a test in LLD. Also improve the log message we emit when we fail to rewrite type indices in LLD. That's how I found this bug. llvm-svn: 316461
* [codeview] Add support for inlinee listsReid Kleckner2017-10-231-0/+1
| | | | | | | | | | | This adds type index discovery and dumper support for symbol record kind 0x1168, which is a list of inlined function ids. This symbol kind is undocumented, but S_INLINEES is consistent with the existing nomenclature. Fixes PR34222 llvm-svn: 316398
* [codeview] Recognize two records with no type index fieldsReid Kleckner2017-10-231-0/+2
| | | | | | | | Thunk records do not have types and frame cookies do not have types. These were found while linking libconcrt.lib from MSVC. llvm-svn: 316385
* [llvm-dwarfdump] - Teach tool about few GNU call_sites constants.George Rimar2017-10-231-1/+2
| | | | | | | | | | | | | | This teaches tool about following consants: DW_TAG_GNU_call_site, DW_TAG_GNU_call_site_parameter, DW_AT_GNU_call_site_value, DW_AT_GNU_all_call_sites. Constants documented here: https://sourceware.org/elfutils/DwarfExtensions Differential revision: https://reviews.llvm.org/D39119 llvm-svn: 316321

* [llvm-dwarfdump] - Teach tool to parse DW_CFA_GNU_args_size.George Rimar2017-10-161-0/+1
| | | | | | | | | Currently llvm-dwarfdump runs into llvm_unreachable when faces DW_CFA_GNU_args_size. Patch implements the support. Differential revision: https://reviews.llvm.org/D38879 llvm-svn: 315897
* Re-land "[llvm-dwarfdump] Print type names in DW_AT_type DIEs"Jonas Devlieghere2017-10-102-6/+66
| | | | | | | | | | | | This patch adds printing for DW_AT_type DIEs like it is already the case for DW_AT_specification DIEs. This is a rather naive approach and only a start. We should have pretty printers for different languages. Recommit after being reverted in r315299. Differential revision: https://reviews.llvm.org/D36993 llvm-svn: 315316

* [dwarfdump] Verify that unit type matches root DIEJonas Devlieghere2017-10-061-8/+24
| | | | | | | | | | | | | This patch adds two new verifiers: - It checks that the root DIE of a CU is actually a valid unit DIE. (based on its tag) - For DWARF5 which contains a unit type int he CU header, it checks that this matches the type of the unit DIE.

* CodeView: Provide a .def file with the register idsHans Wennborg2017-10-032-98/+8
| | | | | | | | | | | | | | The list of register ids was previously written out in a couple of dirrent places. This puts it in a .def file and also adds a few more registers (e.g. the x87 regs) which should lead to more readable dumps, but I didn't include the whole list since that seems unnecessary. X86_MC::initLLVMToSEHAndCVRegMapping is pretty ugly, but at least it's not relying on magic constants anymore. The TODO of using tablegen still stands.

* [dwarfdump] Add -lookup optionJonas Devlieghere2017-10-032-2/+30
| | | | | | | | | Add the option to lookup an address in the debug information and print out the file, function, block and line table details. Differential revision: https://reviews.llvm.org/D38409 llvm-svn: 314817
* CodeView symbol dumper: use symbolic names for registersHans Wennborg2017-10-021-4/+7
| | | | | | https://reviews.llvm.org/D38469 llvm-svn: 314690
* [dwarfdump] Add -show-formJonas Devlieghere2017-10-021-1/+1
| | | | | | | | | This enables printing of DWARF form types after the DWARF attribute types. Differential revision: https://reviews.llvm.org/D38459 llvm-svn: 314685
* [dwarfdump][NFC] Consistent printing of address rangesJonas Devlieghere2017-09-292-8/+8
| | | | | | | | | | | | | | This implement the insertion operator for DWARF address ranges so they are consistently printed as [LowPC, HighPC). While a dump method might have felt more consistent, it is used exclusively for printing error messages in the verifier and never used for actual dumping. Hence this approach is more intuitive and creates less clutter at the call sites. Differential revision: https://reviews.llvm.org/D38395 llvm-svn: 314523
* [dwarfdump][NFC] Consistent errors and warnings with --verifyJonas Devlieghere2017-09-293-88/+118
| | | | | | | | | | | This patch introduces 3 helper functions: error(), warn() and note() to make printing during verification more consistent. When supported, the respective prefixes are printed in color using the same color scheme as clang. Differential revision: https://reviews.llvm.org/D38368 llvm-svn: 314498
* llvm-dwarfdump: support .apple-namespaces in --findAdrian Prantl2017-09-291-15/+13
| | | | llvm-svn: 314481
* llvm-dwarfdump: add support for .apple_types in --findAdrian Prantl2017-09-291-2/+6
| | | | llvm-svn: 314479
* llvm-dwarfdump: implement --find for .apple_namesAdrian Prantl2017-09-282-3/+87
| | | | | | | | | | | | This patch implements the dwarfdump option --find=<name>. This option looks for a DIE in the accelerator tables and dumps it if found. This initial patch only adds support for .apple_names to keep the review small, adding the other sections and pubnames support should be trivial though. Differential Revision: https://reviews.llvm.org/D38282 llvm-svn: 314439
* [dwarfdump] Verify that CUs have a unit DIE.Jonas Devlieghere2017-09-281-3/+8
| | | | | | | | | This patch adds a check to the DWARF verifier to detect CUs without a unit DIE. Differential revision: https://reviews.llvm.org/D38363 llvm-svn: 314426
* [dwarfdump] Fix printing of .debug_line offset.Jonas Devlieghere2017-09-271-1/+1
| | | | | | | | | Fixes 32-bit buildbots: http://bb.pgr.jp/builders/test-llvm-i686-linux-RA/builds/542 http://lab.llvm.org:8011/builders/clang-cmake-thumbv7-a15/builds/11533 http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15/builds/11494 llvm-svn: 314291
* [dwarfdump] Add support for -debug-line=OFFSETJonas Devlieghere2017-09-271-0/+3
| | | | | | | | This patch adds support for passing an offset to -debug-line. Differential revision: https://reviews.llvm.org/D38240 llvm-svn: 314288
* [dwarfdump] Add support for -debug-loc=OFFSETJonas Devlieghere2017-09-272-6/+48
| | | | | | | | This patch adds support for passing an offset to -debug-loc. Differential revision: https://reviews.llvm.org/D38237 llvm-svn: 314286
* [dwarfdump] Skip 'stripped' sectionsJonas Devlieghere2017-09-261-0/+4
| | | | | | | | | | | | | | | | | | | When dsymutil generates the companion file, its strips all unnecessary sections by omitting their body and setting the offset in their corresponding load command to zero. One such section is the .eh_frame section, as it contains runtime information rather than debug information and is part of the __TEXT segment. When reading this section, we would just read the number of bytes specified in the load command, starting from offset 0 (i.e. the beginning of the file). Rather than trying to parse this obviously invalid section, dwarfdump now skips this. Differential revision: https://reviews.llvm.org/D38135 llvm-svn: 314208
* [dwarfdump] Add verbose output for .debug-line sectionJonas Devlieghere2017-09-212-8/+83
| | | | | | | | | | | | This patch adds dumping of line table instructions as well as the final state at each specified pc value in verbose mode. This is essentially the same as the default in Darwin's dwarfdump. Dumping the actual line table opcodes can be particularly useful for something like debugging a bad `.debug_line` section. Differential revision: https://reviews.llvm.org/D37971 llvm-svn: 313910

| | | | llvm-svn: 313900
* [DWARF] Shrink AttributeSpec from 24 to 16 bytes.Benjamin Kramer2017-09-211-11/+10
| | | | | | | This is a bit ugly because we can't put Optional into a union. Hide all of that behind a set of accessors and make accesses safer using asserts. llvm-svn: 313884
* llvm-dwarfdump: implement --recurse-depth=<N>Adrian Prantl2017-09-205-21/+24
| | | | | | | | | | This patch implements the Darwin dwarfdump option --recurse-depth=<N>, which limits the recursion depth when selectively printing DIEs at an offset. Differential Revision: https://reviews.llvm.org/D38064 llvm-svn: 313778
* dwarfdump/symbolizer: Avoid loading unneeded CUs from a DWPDavid Blaikie2017-09-193-9/+11
| | | | | | | | When symbolizing large binaries, parsing every CU in a DWP file is a significant performance penalty. Instead, use the index to only load the CUs that are needed. llvm-svn: 313659
* dwarfdump: Delay parsing abbreviations until they're neededDavid Blaikie2017-09-192-10/+33
| | | | | | | | | | | This speeds up dumping specific DIEs by not parsing abbreviations for units that are not used. (this is also handy to have in eventually to speed up llvm-symbolizer for .dwp files, where parsing most of the DWP file can be avoided by using the index) llvm-svn: 313635
