* DWARF: Unify form size handling codePavel Labath2018-03-141-53/+0
| | | | | | | | | | | | | | | | | Summary: This patch replaces the two switches which are deducing the size of various forms with a single implementation. I have put the new implementation into BinaryFormat, to avoid introducing dependencies between the two independent libraries (DebugInfo and CodeGen) that need this functionality.

* Recommit "[DWARFv5] Dump an MD5 checksum in the line-table header."Paul Robinson2017-12-181-0/+12
| | | | | | | | | | | Adds missing support for DW_FORM_data16. Update of r320852/r320886, fixing the unittest again, this time use a raw char string for the test data. Differential Revision: https://reviews.llvm.org/D41090 llvm-svn: 321011

| | | | | | | | | | | Adds missing support for DW_FORM_data16. Update of r320852, fixing the unittest to use a hand-coded struct instead of std::array to guarantee data layout. Differential Revision: https://reviews.llvm.org/D41090 llvm-svn: 320886

| | | | | | | | Supporting this form in .debug_line.dwo will be done as a follow-up. Differential Revision: https://reviews.llvm.org/D33155 llvm-svn: 317607
* [DWARF] NFC: DWARFDataExtractor combines relocs with DataExtractor.Paul Robinson2017-06-291-4/+4
| | | | | | | | | | | Requires callers to directly associate relocations with a DataExtractor used to read data from a DWARF section, which helps a callee not make assumptions about which section it is reading. This is the next step in reducing DWARFFormValue's dependence on DWARFUnit. Differential Revision: https://reviews.llvm.org/D34704 llvm-svn: 306699
* [DWARF] NFC: Collect info used by DWARFFormValue into a helper.Paul Robinson2017-06-261-10/+19
| | | | | | | | | | | Some forms have sizes that depend on the DWARF version, DWARF format (32/64-bit), or the size of an address. Collect these into a struct to simplify passing them around. Require callers to provide one when they query a form's size. Differential Revision: http://reviews.llvm.org/D34570 llvm-svn: 306315
* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* Clean up DWARFFormValue by reducing duplicated code and removing ↵Greg Clayton2016-11-111-10/+41
| | | | | | | | | | | | | | | | | | | | | DWARFFormValue::getFixedFormSizes() In preparation for a follow on patch that improves DWARF parsing speed, clean up DWARFFormValue so that we have can get the fixed byte size of a form value given a DWARFUnit or given the version, address byte size and dwarf32/64. This patch cleans up code so that everyone is using one of the new DWARFFormValue functions: static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, const DWARFUnit *U = nullptr); static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, uint16_t Version, uint8_t AddrSize, bool Dwarf32); This patch changes DWARFFormValue::skipValue() to rely on the output of DWARFFormValue::getFixedByteSize(...) instead of duplicating the code in each function. This will reduce the number of changes we need to make to DWARF to fewer places in DWARFFormValue when we add support for new form. This patch also starts to support DWARF64 so that we can get correct byte sizes for forms that vary according the DWARF 32/64. To reduce the code duplication a new FormSizeHelper pure virtual class was created that can be created as a FormSizeHelperDWARFUnit when you have a DWARFUnit, or FormSizeHelperManual where you manually specify the DWARF version, address byte size and DWARF32/DWARF64. There is now a single implementation of a function that gets the fixed byte size (instead of two where one took a DWARFUnit and one took the DWARF version, address byte size and DWARFFormat enum) and one function to skip the form values. https://reviews.llvm.org/D26526 llvm-svn: 286597
* Switch all DWARF variables for tags, attributes and forms over to use the ↵Greg Clayton2016-10-271-2/+2
| | | | | | | | llvm::dwarf enumerations instead of using raw uint16_t values. This allows easier debugging as users can see the values of the enumerations in the variables view that will show the enumeration string instead of just a number. https://reviews.llvm.org/D26013 llvm-svn: 285309
* [NFC] Header cleanupMehdi Amini2016-04-181-0/+1
| | | | | | | | | | | | | | Removed some unused headers, replaced some headers with forward class declarations.

* Resubmit unittests for DebugInfoPDB.Zachary Turner2015-02-071-0/+49
These were originally submitted as part of r228428, but this part caused a build breakage in LLVMConfig. The library portion was resubmitted independently since it was not causing breakage. There were two reasons this was causing the build to fail. The first is that there were no Makefiles added for the PDB tests. And the second is that the DebugInfoPDB library was only being built by CMake behind an "if (MSVC)" check. This is wrong since this the library hides platform specific details, and it was causing LLVM-Config to not find the library when trying to build unittests. llvm-svn: 228482
