* Add R600 builtin codegen.Matt Arsenault2014-06-24
| | | | git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211631 91177308-0d34-0410-b5e6-96231b3b80d8
* Correctly Load Mixed FP-GP Variadic Arguments for x86-64.Rafael Espindola2014-06-24
| | | | | | | | | | | | | | | | | | | | According to the x86-64 ABI, structures with both floating point and integer members are split between floating-point and general purpose registers, and consecutive 32-bit floats can be packed into a single floating point register. In the case of variadic functions these are stored to memory and the position recorded in the va_list. This was already correctly implemented in llvm.va_start. The problem is that the code in clang for implementing va_arg was reading floating point registers from the wrong location. Patch by Thomas Jablin. Fixes PR20018. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211626 91177308-0d34-0410-b5e6-96231b3b80d8

* Objective-C. When we use @selector(save:), etc. there may be more Fariborz Jahanian2014-06-24
| | | | | | | | | | | | | | than one method with mismatched type of same selector name. clang issues a warning to point this out since it may cause undefined behavior. There are cases though that some APIs don't care about user methods and such warnings are perceived as noise. This patch allows users to add paren delimiters around selector name to turn off such warnings. So, @selector((save:)) will turn off the warning. It also provides 'fixit' so user knows what to do. // rdar://16458579 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211611 91177308-0d34-0410-b5e6-96231b3b80d8
* Add new debug kind LocTrackingOnly.Diego Novillo2014-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This new debug emission kind supports emitting line location information in all instructions, but stops code generation from emitting debug info to the final output. This mode is useful when the backend wants to track source locations during code generation, but it does not want to produce debug info. This is currently used by optimization remarks (-Rpass, -Rpass-missed and -Rpass-analysis). When one of the -Rpass flags is used, the front end will enable location tracking, only if no other debug option is enabled. To prevent debug information from being generated, a new debug info kind LocTrackingOnly causes DIBuilder::createCompileUnit() to not emit the llvm.dbg.cu annotation. This blocks final code generation from generating debug info in the back end. Depends on D4234.

* AST: Address of dllimport functions isn't constantDavid Majnemer2014-06-24
| | | | | | | | | | | | | | | | The address of dllimport functions can be accessed one of two ways: - Through the IAT which is symbolically referred to with a symbol starting with __imp_. - Via the wrapper-function which ends up calling through the __imp_ symbol. The problem with using the wrapper-function is that it's address will not compare as equal in all translation units. Specifically, it will compare unequally with the translation unit which defines the function. This fixes PR19955. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211570 91177308-0d34-0410-b5e6-96231b3b80d8

* Driver: enhance MSC version compatibilitySaleem Abdulrasool2014-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | The version information for Visual Studio is spread over multiple variables. The newer Windows SDK has started making use of some of the extended versioning variables that were previously undefined. Enhance our compatibility definitions for these cases. _MSC_VER is defined to be the Major * 100 + Minor. _MSC_FULL_VER is defined to be Major * 10000000 + Minor * 100000 + Build. And _MSC_BUILD is the build revision of the compiler. Extend the -fmsc-version option in a compatible manner. If the value is the previous form of MMmm, then we assume that the build number is 0. Otherwise, a specific build number may be passed by using the form MMmmbbbbb. Due to bitwidth limitations of the option, it is currently not possible to define a revision value. The version information can be passed as either the decimal encoded value (_MSC_FULL_VER or _MSC_VER) or as a dot-delimited value. The change to the TextDiagnostic is to deal with the updated encoding of the version information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211420 91177308-0d34-0410-b5e6-96231b3b80d8
* Driver: Record that we're in crashdump and push flags to ConstructJobJustin Bogner2014-06-20

* [PowerPC] Fix small argument stack slot offset for LEUlrich Weigand2014-06-20
| | | | | | | | | | | | | | | | | | | When small arguments (structures < 8 bytes or "float") are passed in a stack slot in the ppc64 SVR4 ABI, they must reside in the least significant part of that slot. On BE, this means that an offset needs to be added to the stack address of the parameter, but on LE, the least significant part of the slot has the same address as the slot itself. For the most part, this is handled in the LLVM back-end, where I just fixed the LE case in commit r211368. However, there is one piece of the clang front-end that is also aware of these stack-slot offsets: PPC64_SVR4_ABIInfo::EmitVAArg. This patch updates that routine to take endianness into account. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@211370 91177308-0d34-0410-b5e6-96231b3b80d8
