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

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

Move C++ code out of the C headers and into either C++ headers

or the C++ files themselves. This enables people to use just a C compiler to interoperate with LLVM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180063 91177308-0d34-0410-b5e6-96231b3b80d8

[ASan] Allow disabling init-order checks for globals by source file name.

Minor simplification.

Go ahead and use the full path for both the .gcno and .gcda files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178302 91177308-0d34-0410-b5e6-96231b3b80d8

[tsan] make sure memset/memcpy/memmove are not inlined in tsan mode

2013-03-28T11:21:13Z

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178230 91177308-0d34-0410-b5e6-96231b3b80d8

Use the full path when outputting the `.gcda' file.

2013-03-26T22:47:50Z

If we compile a single source program, the `.gcda' file will be generated where the program was executed. This isn't desirable, because that place may be at an unpredictable place (the program could call `chdir' for instance). Instead, we will output the `.gcda' file in the same place we output the `.gcno' file. I.e., the directory where the executable was generated. This matches GCC's behavior. & PR11809 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178084 91177308-0d34-0410-b5e6-96231b3b80d8

[ASan] Change the ABI of __asan_before_dynamic_init function: now it takes pointer to private string with module name. This string serves as a unique module ID in ASan runtime. LLVM part

[asan] Change the way we report the alloca frame on stack-buff-overflow.

2013-03-22T10:37:20Z

Before: the function name was stored by the compiler as a constant string and the run-time was printing it. Now: the PC is stored instead and the run-time prints the full symbolized frame. This adds a couple of instructions into every function with non-empty stack frame, but also reduces the binary size because we store less strings (I saw 2% size reduction). This change bumps the asan ABI version to v3. llvm part.
