* [WebAssembly] Improve readobj and nm support for wasmSam Clegg2017-04-145-46/+102
| | | | | | | | | Now that the libObect support for wasm is better we can have readobj and nm produce more useful output too. Differential Revision: https://reviews.llvm.org/D31514 llvm-svn: 300365
* [codeview] Cope with unsorted streams in type mergingReid Kleckner2017-04-034-0/+59
| | | | | | | | | | | | | | | Summary: MASM can produce type streams that are not topologically sorted. It can even produce type streams with circular references, but those are not common in practice. Reviewers: inglorion, ruiu Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D31629 llvm-svn: 299403
* [codeview] Add support for label type recordsReid Kleckner2017-04-032-0/+16
| | | | | | MASM can produce these type records. llvm-svn: 299388
* [WebAssembly] Improve support for WebAssembly binary formatDerek Schuff2017-03-302-1/+1
| | | | | | | | | | | | | | | | | | | Mostly this change adds support converting to and from YAML which will allow us to write more test cases for the WebAssembly MC and lld ports. Better support for objdump, readelf, and nm will be in followup CLs. I had to update the two wasm test binaries because they used the old style 'name' section which is no longer supported. Differential Revision: https://reviews.llvm.org/D31099 Patch by Sam Clegg llvm-svn: 299101
* [codeview] Fix buggy BeginIndexMapSize assertionReid Kleckner2017-03-292-0/+29
| | | | | | | | | | | This assert is just trying to test that processing each record adds exactly one entry to the index map. The assert logic was wrong when the first record in the type stream was a field list. I've simplified the code by moving the LF_FIELDLIST-specific logic into the callback for that record type. llvm-svn: 299035
* [PDB] Split item and type records when merging type streamsReid Kleckner2017-03-241-4/+52

* [llvm-readobj] - Teach readobj to print PT_OPENBSD_BOOTDATA headerGeorge Rimar2016-12-061-1/+15
| | | | | | | | | | | | | These are OpenBSD specific program headers. OpenBSD commit: https://github.com/openbsd/src/commit/d39116912b9536bd77326260dc5c6e593fd4ee24 It is required for fixing PR31288. Differential revision: https://reviews.llvm.org/D27456 llvm-svn: 288831
* llvm-readobj: Use hash tables to print dynamic symbols.Hemant Kulkarni2016-11-231-0/+28
| | | | | | | -symbols prints both .symtab and .dynsym symbols for GNU style in ELF. -dyn-symbols prints symbols looking up through hash tables. This helps validate hash tables. llvm-svn: 287786
* AArch64 ILP32 relocations for assembly and ELFJoel Jones2016-10-242-0/+91
| | | | | | | | | | | | | | | | | | | Summary: Add relocations for AArch64 ILP32. Includes: - Addition of definitions for R_AARCH32_* - Definition of new -target-abi: ilp32 - Definition of data layout string - Tests for added relocations.

* llvm-readobj: add support for printing GNU NotesSaleem Abdulrasool2016-08-301-0/+76
| | | | | | | | | Add support for printing the GNU Notes. This allows an easy way to view the build id for a binary built with the build id. Currently, this only handles the GNU notes, though it would be easy to extend for other note types (default, FreeBSD, NetBSD, etc). Only the GNU style is supported currently. llvm-svn: 280131
* llvm-readobj: handle import libraries with -coff-exportsSaleem Abdulrasool2016-08-182-0/+22
| | | | | | | | `link -dump -exports` lists exported symbols from import libraries as well as normal dlls. Ensure that we can handle import libraries as well in llvm-readobj. llvm-svn: 279069
* [lanai] Update ELF number to correspond to the assigned number.Jacques Pienaar2016-06-283-1/+1
| | | | | | Change EM_LANAI to correspond to machine number assigned by Xinuos. llvm-svn: 274042
* [yaml2obj] Remove --format option in favor of YAML tagsChris Bieneman2016-06-273-8/+10
| | | | | | | | | | | | | | | | | | | | | | Summary: Our YAML library's handling of tags isn't perfect, but it is good enough to get rid of the need for the --format argument to yaml2obj. This patch does exactly that. Instead of requiring --format, it infers the format based on the tags found in the object file. The supported tags are: !ELF !COFF !mach-o !fat-mach-o I have a corresponding patch that is quite large that fixes up all the in-tree test cases.

* [llvm-readobj] - Teach llvm-readobj to print dependencies of SHT_GNU_verdef ↵George Rimar2016-06-221-34/+23
| | | | | | | | | | | | | | | and refactor dumping method. This patch changes single method of llvm-readobj. It teaches SHT_GNU_verdef dumper to print version dependencies, also it removes few fields from output that can be dumped with other keys and slightly refactors code. Testcase was also modified to match the changes. Change is required for testcases of upcoming lld patches. Differential revision: http://reviews.llvm.org/D21552 llvm-svn: 273417
* [llvm-readobj] - Teach llvm-readobj to dump .gnu.version_r sectionsGeorge Rimar2016-06-072-0/+33
| | | | | | | | | | SHT_GNU_verneed (.gnu.version_r) is a version dependency section. It was the last symbol versioning relative section that was not dumped, now it is. Differential revision: http://reviews.llvm.org/D21024 llvm-svn: 271998
* [COFF] Expose the PE debug data directory and dump itReid Kleckner2016-06-022-0/+34
| | | | | | | | | | | | This directory is used to find if there is a PDB associated with an executable. I plan to use this functionality to teach llvm-symbolizer whether it should use DIA or DWARF to symbolize a given DLL.

* [llvm-readobj] - Teach readobj to recognize SHF_COMPRESSED flag.George Rimar2016-05-212-0/+9
| | | | | | | | | | | | | | | | | | | | | | | Main problem here was that SHF_COMPRESSED has the same value with XCORE_SHF_CP_SECTION, which was included as standart (common) flag. As far I understand xCore is a family of controllers and it that means it's constant should be processed separately, only if e_machine == EM_XCORE, otherwise llvm-readobj would output different constants twice for compressed section: Flags [ .. SHF_COMPRESSED (0x800) .. XCORE_SHF_CP_SECTION (0x800) .. ] what probably does not make sence if you're not working with xcore file.

* [codeview] Test serialization of all known type recordsReid Kleckner2016-05-172-0/+95
| | | | | | | | | | | This just checks that we emit all type records once, and then after merging the type stream with no other type streams, we still emit every kind of type record. We could test the dumper output more closely, but that would make the test very brittle. Currently we're just getting coverage. llvm-svn: 269778
* [codeview] Add type stream merging prototypeReid Kleckner2016-05-143-0/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This code is intended to be used as part of LLD's PDB writing. Until that exists, this is exposed via llvm-readobj for testing purposes. Type stream merging uses the following algorithm: - Begin with a new empty stream, and a new empty hash table that maps from type record contents to new type index. - For each new type stream, maintain a map from source type index to destination type index. - For each record, copy it and rewrite its type indices to be valid in the destination type stream. - If the new type record is not already present in the destination stream hash table, append it to the destination type stream, assign it the next type index, and update the two hash tables. - If the type record already exists in the destination stream, discard it and update the type index map to forward the source type index to the existing destination type index.

| | | | | | | | | .MIPS.options section specifies miscellaneous options to be applied to an object file. LLVM as well as modern versions of GNU tools emit the only type of the options - ODK_REGINFO.
