* CodeGen: refactor ARM builtin handlingSaleem Abdulrasool2014-12-042-20/+22
| | | | | | | | Create a helper function to construct a value for the ARM hint intrinsic rather than inling the construction. In order to avoid the use of the sentinel value, inline the use of intrinsic instruction retrieval. NFC. llvm-svn: 223338

* CUDA host device code with two code pathsReid Kleckner2014-12-034-13/+65
| | | | | | | | | | | | | | | | | | | | | | | Summary: Allow CUDA host device functions with two code paths using __CUDA_ARCH__ to differentiate between code path being compiled. For example: __host__ __device__ void host_device_function(void) { #ifdef __CUDA_ARCH__ device_only_function(); #else host_only_function(); #endif } Patch by Jacques Pienaar.

* Cast vtable address points to i32 (...)** to enable more globaloptReid Kleckner2014-12-031-4/+8
| | | | | | | | | | | | We currently use i32 (...)** as the type of the vptr field in the LLVM struct type. LLVM's GlobalOpt prefers any bitcasts to be on the side of the data being stored rather than on the pointer being stored to.

* Fix incorrect codegen for devirtualized calls to virtual overloaded operators.Nico Weber2014-12-033-59/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider this program: struct A { virtual void operator-() { printf("base\n"); } }; struct B final : public A { virtual void operator-() override { printf("derived\n"); } }; int main() { B* b = new B; -static_cast<A&>(*b); } Before this patch, clang saw the virtual call to A::operator-(), figured out that it can be devirtualized, and then just called A::operator-() directly, without going through the vtable. Instead, it should've looked up which operator-() the call devirtualizes to and should've called that. For regular virtual member calls, clang gets all this right already. So instead of giving EmitCXXOperatorMemberCallee() all the logic that EmitCXXMemberCallExpr() already has, cut the latter function into two pieces, call the second piece EmitCXXMemberOrOperatorMemberCallExpr(), and use it also to generate code for calls to virtual member operators. This way, virtual overloaded operators automatically don't get devirtualized if they have covariant returns (like it was done for regular calls in r218602), etc. This also happens to fix (or at least improve) codegen for explicit constructor calls (`A a; a.A::A()`) in MS mode with -fsanitize-address-field-padding=1. (This adjustment for virtual operator calls seems still wrong with the MS ABI.) llvm-svn: 223185

We can simply use our __int128 arithmetic to implement this, we generate great code for it: movq %rdx, %rax mulq %rcx movq %rdx, (%r8) retq Differential Revision: http://reviews.llvm.org/D6486 llvm-svn: 223175

* Fix invalid calling convention used for libcalls on ARM.Anton Korobeynikov2014-12-025-9/+52
| | | | | | | | | | | | | | | | ARM ABI specifies that all the libcalls use soft FP ABI (even hard FP binaries). These days clang emits _mulsc3 / _muldc3 calls with default (C) calling convention which would be translated into AAPCS_VFP LLVM calling and thus the result of complex multiplication will be bogus. Introduce a way for a target to specify explicitly calling convention for libcalls. Right now this is temporary correctness fix. Ultimately, we'll end with intrinsic for complex multiplication and all calling convention decisions for libcalls will be put into backend. llvm-svn: 223123

The warnings are different depending on the "danger" of the operation. Defining macro that replaces a keyword is on by default. Other cases produce warning that is off by default but can be turned on using option -Wreserved-id-macro. This change fixes PR11488.

For instance, diagnostic messages for failed module builds give a path relative to the "module root" rather than an absolute file path, and the contents of the module includes file is no longer dependent on what files the including TU happened to inspect prior to triggering the module build. llvm-svn: 223095

| | | | | | | | | | | Richard rejected my Sema change to interpret an integer literal zero in a varargs context as a null pointer, so -Wsentinel sees an integer literal zero and fires off a warning. Only CodeGen currently knows that it promotes integer literal zeroes in this context to pointer size on Windows. I didn't want to teach -Wsentinel about that compatibility hack.

* AArch64: simplify PCS mapping.Tim Northover2014-11-271-122/+30
| | | | | | | | | | | | Now that LLVM can count the registers needed to implement AAPCS rules, we don't need to duplicate that logic here. This means we can drop the explicit padding and also use more natural types in many cases (e.g. "struct { float arr[3]; }" used to end up as "[2 x double]" to avoid holes on the stack. The one wrinkle is that AAPCS va_arg was also using the register counting machinery. But the local replacement isn't too bad. llvm-svn: 222904
