* [ObjectYAML] Add support for DWARF5 Unit headerChris Bieneman2017-03-071-2/+9
| | | | | | In DWARF5 the Unit header added a new field, UnitType, and swapped the order of the address size and abbreviation offset fields. llvm-svn: 297183
* [ObjectYAML] Support for DW_FORM_implicit_const DWARF5 formChris Bieneman2017-03-061-0/+2
| | | | | | | | This patch adds support to the DWARF YAML reader and writer for the new DWARF5 abbreviation form, DW_FORM_implicit_const. The attribute was added in r291599. llvm-svn: 297091
* [ObjectYAML] NFC. Refactor DWARFYAML CompileUnit dump codeChris Bieneman2017-03-061-122/+59
| | | | | | | | | | | | Summary: This patch refactors the DWARFYAML code for dumping compile units to use a visitor pattern. Using this design will, in the future, enable the DWARF YAML code to perform analysis and mutations of the DWARF DIEs. An example of such mutations would be calculating the length of a compile unit and updating the CU's Length field before writing the DIE. This support will make it easier to craft or modify DWARF tests by hand.

* [ObjectYAML] [DWARF] Abstract DWARF Initial Length valuesChris Bieneman2017-03-031-9/+12
| | | | | | | | In the DWARF 4 Spec section 7.2.2, data in many DWARF sections, and some DWARF structures start with "Initial Length Values", which are a 32-bit length, and an optional 64-bit length if the 32 bit value == UINT32_MAX. This patch abstracts the Initial Length type in YAML, and extends its use to all the DWARF structures that are supported in the DWARFYAML code that have Initial Length values. llvm-svn: 296911

* [DWARF] [ObjectYAML] Adding APIs for unittestingChris Bieneman2017-01-201-0/+39
| | | | | | | | | | | | Summary: This patch adds some new APIs to enable using the YAML DWARF representation in unit tests. The most basic new API is DWARFYAML::EmitDebugSections which converts a YAML string into a series of owned MemoryBuffer objects stored in a StringMap. The string map can then be used to construct a DWARFContext for parsing in place of an ObjectFile.

* [ObjectYAML] Pull yaml2dwarf out of yaml2obj for reuseChris Bieneman2017-01-121-0/+332
This patch pulls the yaml2dwarf code out of yaml2obj into a new set of DWARF emitter functions in the DWARFYAML namespace. This will enable the YAML->DWARF code to be used inside DWARF tests by populating the DWARFYAML structs and calling the Emitter functions. llvm-svn: 291828
