* Revive the error message from "process load" and SBProcess::LoadImage.Jim Ingham2016-06-081-1/+1
| | | | | | | | | | | IsPointedCString has problems with ValueObjects of type eTypeHostAddress. We should figure out the right thing to do in that case, but the test is silly here because we're reading a type we've defined, so we know it is a const char *, and if the memory is good, we won't be able to read any characters, when we do ReadPointedString. <rdar://problem/26612812> llvm-svn: 272087
* [AArch64][RegisterBankInfo] Use the generic implementation of copyCost.Quentin Colombet2016-06-081-1/+2
| | | | | | Long term we may want to give high cost at FPR to/from GPR copies. llvm-svn: 272086
* [RegisterBankInfo] Adapt the copy cost logic to give something sane by default.Quentin Colombet2016-06-081-1/+5
| | | | | | | | The generic implementation stated that all copies were free, which is unlikely. Now, only the copies within the same register bank are free. We assume they will get coalesced. llvm-svn: 272085
* [RegisterBankInfo] Add a size argument for the cost of copy.Quentin Colombet2016-06-084-8/+19

* [profile] Hide a few external symbols (NFCI)Vedant Kumar2016-06-083-4/+5

* [Sema] Teach CheckPlaceholderExpr about unaddressable functions.George Burgess IV2016-06-085-25/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given the following C++: ``` void foo(); void foo() __attribute__((enable_if(false, ""))); bool bar() { auto P = foo; return P == foo; } ``` We'll currently happily (and correctly) resolve `foo` to the `foo` overload without `enable_if` when assigning to `P`. However, we'll complain about an ambiguous overload on the `P == foo` line, because `Sema::CheckPlaceholderExpr` doesn't recognize that there's only one `foo` that could possibly work here. This patch teaches `Sema::CheckPlaceholderExpr` how to properly deal with such cases. Grepping for other callers of things like `Sema::ResolveAndFixSingleFunctionTemplateSpecialization`, it *looks* like this is the last place that needed to be fixed up. If I'm wrong, I'll see if there's something we can do that beats what amounts to whack-a-mole with bugs. llvm-svn: 272080
* [ItaniumMangle] Mangle dependent __underlying_type correctlyDavid Majnemer2016-06-082-1/+11
| | | | | | | | | | We attempted to use the UnaryTransformType's UnderlyingType instead of it's BaseType. This is not correct for dependent UnaryTransformType because the have no underlying type. This fixes PR28045. llvm-svn: 272079

* IR: Call dropAllReferences from GlobalVariable's destructor.Peter Collingbourne2016-06-081-0/+2
| | | | | | | | | | | | | We were previously failing to do this and as a result failing to drop attached metadata. Not sure if there's a good way to test this. An in-progress patch exposed this problem by allocating a GlobalVariable at the same address as a previously allocated GlobalVariable.

* [esan] Intercept calloc to avoid deadlocks with tcmallocDerek Bruening2016-06-081-2/+52
| | | | | | | | | | | | | | | | | | Summary: When tcmalloc initializes before esan, esan's initialization ends up calling back into tcmalloc due to the calloc done by dlsym. This results in a deadlock. We avoid this by special-casing this single allocation. Intercepting calloc also gives us the opportunity to act on its zeroing as stores by the application.

* [LibFuzzer] Declare and use sanitizer functions in ``fuzzer::ExternalFunctions``Dan Liew2016-06-078-73/+84
| | | | | | | | | | | | | | | | | | | | | | | This fixes linking problems on OSX. Unfortunately it turns out we need to use an instance of the ``fuzzer::ExternalFunctions`` object in several places so this commit also replaces all instances with a single global instance. It also turns out initializing a global ``fuzzer::ExternalFunctions`` before main is entered (i.e. letting the object be initialised by the global initializers) is not safe (on OSX the call to ``Printf()`` in the CTOR crashes if it is called from a global initializer) so we instead have a global ``fuzzer::ExternalFunctions*`` and initialize it inside ``FuzzerDriver()``. Multiple unit tests depend also depend on the ``fuzzer::ExternalFunctions*`` global so a ``main()`` function has been added that initializes it before running any tests.

* Fix a memory leak in InstructionLLVMC where it held onto a strong reference ↵Greg Clayton2016-06-074-300/+394
| | | | | | | | | | | | | | | | | | | | | to the DisassemblerLLVMC which in turn had a vector of InstructionSP causing the strong cycle. This is fixed now. Rules are as follows for internal code using lldb::DisassemblerSP and lldb::InstructionSP: 1 - The disassembler needs to stay around as long as instructions do as the Instruction subclass now has a weak pointer to the disassembler 2 - The public API has been fixed so that if you get a SBInstruction, it will hold onto a strong reference to the disassembler in a new InstructionImpl class This will keep code like like: inst = lldb.target.ReadInstructions(frame.GetPCAddress(), 1).GetInstructionAtIndex(0) inst.GetMnemonic() Working as expected (not the SBInstructionList() that was returned by SBTarget.ReadInstructions() is gone, but "inst" has a strong reference inside of it to the disassembler and the instruction. All code inside the LLDB shared library was verified to correctly hold onto the disassembler instance in all places. <rdar://problem/24585496> llvm-svn: 272069

* AMDGPU: Add amdgpu-ps-wqm-outputs function attributesNicolai Haehnle2016-06-072-2/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The presence of this attribute indicates that VGPR outputs should be computed in whole quad mode. This will be used by Mesa for prolog pixel shaders, so that derivatives can be taken of shader inputs computed by the prolog, fixing a bug. The generated code could certainly be improved: if a prolog pixel shader is used (which isn't common in modern OpenGL - they're used for gl_Color, polygon stipples, and forcing per-sample interpolation), Mesa will use this attribute unconditionally, because it has to be conservative. So WQM may be used in the prolog when it isn't really needed, and furthermore a silly back-and-forth switch is likely to happen at the boundary between prolog and main shader parts. Fixing this is a bit involved: we'd first have to add a mechanism by which LLVM writes the WQM-related input requirements to the main shader part binary, and then Mesa specializes the prolog part accordingly. At that point, we may as well just compile a monolithic shader...
