* [codeview] Dump def range lengths in hexReid Kleckner2016-02-111-3/+3
| | | | | | | It makes it easier to correlate with assembly dumps, which are typically given with hex offsets. llvm-svn: 260619

* [codeview] Wire up the .cv_inline_linetable directiveReid Kleckner2016-02-021-1/+1
| | | | | | | | This directive emits the binary annotations that describe line and code deltas in inlined call sites. Single-stepping through inlined frames in windbg now works. llvm-svn: 259535
* [CodeView] Fix dumping the is_stmt bit from the line tableReid Kleckner2016-01-291-1/+1
| | | | | | Bug pointed out by George Rimar. llvm-svn: 259205
* Reland "[CodeView] Use assembler directives for line tables"Reid Kleckner2016-01-291-6/+5
| | | | | | | | This reverts commit r259126 and relands r259117. This time with updated library dependencies. llvm-svn: 259130
* Revert "[CodeView] Use assembler directives for line tables"Reid Kleckner2016-01-291-5/+6
| | | | | | | | | This reverts commit r259117. The LineInfo constructor is defined in the codeview library and we have to link against it now. Doing that isn't trivial, so reverting for now. llvm-svn: 259126
* [CodeView] Use assembler directives for line tablesReid Kleckner2016-01-281-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a new family of .cv_* directives to LLVM's variant of GAS syntax: - .cv_file: Similar to DWARF .file directives - .cv_loc: Similar to the DWARF .loc directive, but starts with a function id. CodeView line tables are emitted by function instead of by compilation unit, so we needed an extra field to communicate this. Rather than overloading the .loc direction further, we decided it was better to have our own directive. - .cv_stringtable: Emits the codeview string table at the current position. Currently this just contains the filenames as null-terminated strings. - .cv_filechecksums: Emits the file checksum table for all files used with .cv_file so far. There is currently no support for emitting actual checksums, just filenames. This moves the line table emission code down into the assembler. This is in preparation for implementing the inlined call site line table format. The inline line table format encoding algorithm requires knowing the absolute code offsets, so it must run after the assembler has laid out the code. David Majnemer collaborated on this patch. llvm-svn: 259117

| | | | llvm-svn: 257777
* [codeview] Print relocations against code and data offset fieldsReid Kleckner2016-01-141-76/+62
| | | | | | | | These fields are almost always zero. However, there are relocations against them, and we should print the relocation symbol with it as SYM+0xNN. llvm-svn: 257776
* [CodeView] Add support for dumping binary annotationsDavid Majnemer2016-01-141-1/+100
| | | | | | | | | | | | Binary annotations are encoded along the lines of UTF-8 and ECI but with a few minor differences. The algorithm specified in "ECMA-335 CLI Section II.3.2 - Blobs and Signatures" is used to compress binary annotations. Signed binary annotations are encoded like unsigned annotations except the sign bit is rotated left to reduce the number of bits needed to be encoded. llvm-svn: 257742
* [codeview] Share more enums across the writer and the dumperReid Kleckner2016-01-131-12/+17
| | | | | | | | | Moves some .def files into include/DebugInfo/CodeView. Aslo remove a 'using namespace' directive from a header in readobj and update the uses of the endian helper types to compensate. llvm-svn: 257712
* [readobj] Expand CodeView dumping functionalityReid Kleckner2016-01-131-140/+1568
| | | | | | | | | | | | | | | | This rewrites and expands the existing codeview dumping functionality in llvm-readobj using techniques similar to those in lib/Object. This defines a number of new records and enums useful for reading memory mapped codeview sections in COFF objects. The dumper is intended as a testing tool for LLVM as it grows more codeview output capabilities. Reviewers: majnemer Differential Revision: http://reviews.llvm.org/D16104 llvm-svn: 257658
* [CodeView] Improve the line table dumperDavid Majnemer2016-01-131-14/+28
| | | | | | | | This change has us print out fields we didn't previously understand. To improve readability, we now group column information with it's respective line. llvm-svn: 257552
* Reland "[llvm-readobj] Simplify usage of -codeview flag"Reid Kleckner2015-12-161-7/+13

* [llvm-readobj] s/FunctionName/LinkageName/ for codeview dumpingReid Kleckner2015-12-151-7/+7
| | | | | | | The symbol being printed in this field comes from the main symbol table, not 0xF1 subsection. Use LinkageName to make that a lot clearer. llvm-svn: 255596
* [COFF] Add IMAGE_SCN_TYPE_NOLOAD to SectionCharacteristicsDavid Majnemer2015-07-301-0/+1

* llvm-readobj: call exit(1) on error.Rafael Espindola2015-07-201-54/+33
| | | | | | | | | llvm-readobj exists for testing llvm. We can safely stop the program the first time we know the input in corrupted. This is in preparation for making it handle a few more broken files. llvm-svn: 242656

* [CodeView] Add support for emitting column informationDavid Majnemer2015-07-091-6/+14
| | | | | | | | | | Column information is present in CodeView when the line table subsection has bit 0 set to 1 in it's flags field. The column information is represented as a pair of 16-bit quantities: a starting and ending column. This information is present at the end of the chunk, after all the line-PC pairs. llvm-svn: 241764
* Check that COFF .obj files have sections with zero virtual address spaces.Rafael Espindola2015-07-061-1/+6
| | | | | | | | | | | | | When talking about the virtual address of sections the coff spec says: ... for simplicity, compilers should set this to zero. Otherwise, it is an arbitrary value that is subtracted from offsets during relocation. We don't currently subtract it, so check that it is zero. If some producer does create such files, we can change getRelocationOffset instead. llvm-svn: 241447
* Return ErrorOr from SymbolRef::getName.Rafael Espindola2015-07-021-3/+9
| | | | | | | | | | | | This function can really fail since the string table offset can be out of bounds. Using ErrorOr makes sure the error is checked. Hopefully a lot of the boilerplate code in tools/* can go away once we have a diagnostic manager in Object. llvm-svn: 241297

* [StackMaps] Add a lightweight parser for stackmap version 1 sections.Lang Hames2015-06-261-1/+31
| | | | | | | | | | The parser provides a convenient interface for reading llvm stackmap v1 sections in object files. This patch also includes a new option for llvm-readobj, '-stackmap', which uses the parser to pretty-print stackmap sections for debugging/testing purposes. llvm-svn: 240860
* Remove object_error::success and use std::error_code() insteadRui Ueyama2015-06-091-1/+1
| | | | | | | | | | | | make_error_code(object_error) is slow because object::object_category() uses a ManagedStatic variable. But the real problem is that the function is called too frequently. This patch uses std::error_code() instead of object_error::success. In most cases, we return "success", so this patch reduces number of function calls to that function. http://reviews.llvm.org/D10333 llvm-svn: 239409
* Modify llvm-readobj to dump symbol record bytes.Zachary Turner2015-02-181-10/+23

* llvm-readobj: add IMAGE_REL_ARM_MOV32(T) to the enumerationSaleem Abdulrasool2015-01-161-0/+1
| | | | | | | Add an additional based relocation to the enumeration of based relocation names. The lack of the enumerator value causes issues when inspecting WoA binaries. llvm-svn: 226314
* llvm-readobj: add support to dump COFF export tablesSaleem Abdulrasool2015-01-031-0/+21
| | | | | | | This enhances llvm-readobj to print out the COFF export table, similar to the -coff-import option. This is useful for testing in lld. llvm-svn: 225120
