PR14492: Debug Info: Support for values of non-integer non-type template parameters.

2013-05-10T21:52:07Z

This is only tested for global variables at the moment (& includes tests for the unnamed parameter case, since apparently this entire function was completely untested previously) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181632 91177308-0d34-0410-b5e6-96231b3b80d8

Add DebugIR pass -- emits IR file and replace source lines with IR lines in MD

2013-05-08T20:44:14Z

- requires existing debug information to be present - fixes up file name and line number information in metadata - emits a "-debug.ll" succinct IR file (without !dbg metadata or debug intrinsics) that can be read by a debugger - initialize pass in opt tool to enable the "-debug-ir" flag - lit tests to follow git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181467 91177308-0d34-0410-b5e6-96231b3b80d8

Pull up AssemblyWriter interface into header to allow subclassing

2013-05-08T20:38:31Z

- made all functions virtual so that subclasses can specialize them - add printInstructionLine so that subclasses can choose whether or not to print the newline character (without having to implement printBasicBlock() - added a second constructor to AssemblyWriter that does not require a SlotTracker, as required in order to keep the SlotTracker helper class outside AsmWriter.h and buried in the implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181466 91177308-0d34-0410-b5e6-96231b3b80d8

Rename DIImportedModule to DIImportedEntity and allow imported declarations

2013-05-07T21:35:53Z

DIBuilder::createImportedDeclaration isn't fully plumbed through (note, lacking in AsmPrinter/DwarfDebug support) but this seemed like a sufficiently useful division of code to make the subsequent patch(es) easier to follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181364 91177308-0d34-0410-b5e6-96231b3b80d8

Fix const merging when an alias of a const is llvm.used.

2013-05-06T01:48:55Z

We used to disable constant merging not only if a constant is llvm.used, but also if an alias of a constant is llvm.used. This change fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181175 91177308-0d34-0410-b5e6-96231b3b80d8

Add ArrayRef constructor from None, and do the cleanups that this constructor enables

Patch by Robert Wilhelm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181138 91177308-0d34-0410-b5e6-96231b3b80d8

This patch breaks up Wrap.h so that it does not have to include all of

2013-05-01T20:59:00Z

the things, and renames it to CBindingWrapping.h. I also moved CBindingWrapping.h into Support/. This new file just contains the macros for defining different wrap/unwrap methods. The calls to those macros, as well as any custom wrap/unwrap definitions (like for array of Values for example), are put into corresponding C++ headers. Doing this required some #include surgery, since some .cpp files relied on the fact that including Wrap.h implicitly caused the inclusion of a bunch of other things. This also now means that the C++ headers will include their corresponding C API headers; for example Value.h must include llvm-c/Core.h. I think this is harmless, since the C API headers contain just external function declarations and some C types, so I don't believe there should be any nasty dependency issues here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180881 91177308-0d34-0410-b5e6-96231b3b80d8

Now that the underlying issue is fixed, revert r180750 and r180722.

2013-05-01T13:07:03Z

The cause of the windows failures was fixed by r180791. Revert to the state after Sabre's original revert. Original message: revert r179735, it has no testcases, and doesn't really make sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180844 91177308-0d34-0410-b5e6-96231b3b80d8

Change getSlotIndex to return unsigned.

2013-04-30T16:53:38Z

The actual storage was already using unsigned, but the interface was using uint64_t. This is wasteful on 32 bits and looks to be the root causes of a miscompilation on Windows where a value was being sign extended to 64bits to compare with the result of getSlotIndex.

Revert the command line option patch. However, keep the part that makes this pass on Windows. I.e., we don't emit the target dependent attributes in a comment before the function.
