* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206822 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Support debug_loc under fissionDavid Blaikie2014-03-25
| | | | | | | | | | | | | | | | | | | | | | Implement debug_loc.dwo, as well as llvm-dwarfdump support for dumping this section. Outlined in the DWARF5 spec and http://gcc.gnu.org/wiki/DebugFission the debug_loc.dwo section has more variation than the standard debug_loc, allowing 3 different forms of entry (plus the end of list entry). GCC seems to, and Clang certainly, only use one form, so I've just implemented dumping support for that for now. It wasn't immediately obvious that there was a good refactoring to share the implementation of dumping support between debug_loc and debug_loc.dwo, so they're separate for now - ideas welcome or I may come back to it at some point. As per a comment in the code, we could choose different forms that may reduce the number of debug_addr entries we emit, but that will require further study. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204697 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify the handling of iterators in ObjectFile.Rafael Espindola2014-01-30
| | | | | | | | | | | | None of the object file formats reported error on iterator increment. In retrospect, that is not too surprising: no object format stores symbols or sections in a linked list or other structure that requires chasing pointers. As a consequence, all error checking can be done on begin() and end().

* DebugInfo: Make pubnames header printing similar to unit header printingDavid Blaikie2013-11-01
| | | | | | | | | | | | | | | In a failed attempt to allow the gnu-public-names.ll test case to not hardcode the size of the unit that the pubnames section referred to I've at least managed to have unit headers and pubnames headers print out in a similar style. This failed to achieve the desired goal because the header in a unit specifies the length of the unit without the length element of the header whereas the length in the pubnames includes this element, so the numbers are off by 4 bytes. I don't know of any arithmetic powers in FileCheck so the test case can't simply say "CU_LENGTH + 4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193872 91177308-0d34-0410-b5e6-96231b3b80d8

* DebugInfo: Wrap section data and relocs together for dwarf dumping supportDavid Blaikie2013-09-23
| | | | | | | | | | | | | | | | | | This is a small step that may enable some simplifications in producer (DWARFContext) and consumer (DWARFCompileUnit and other places) by making a more complete abstraction around the data and relocations for a section. Small initial steps could include simple changes such as passing the pair to DWARFCompileUnit's ctor rather than passing the data and relocs separately. I don't intend to pursue any such changes immediately, however. The motivation for doing this now is that type unit dumping will need to deal with these data+reloc pairs moreso than the existing dumping support has needed to associate the data as type unit sections are named the same (debug_types) and comdat group folded. So to implement dumping and reloc handling we'll need a mapping of section->data+relocs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191209 91177308-0d34-0410-b5e6-96231b3b80d8
