* MS inline asm: Filter MXCSR out of the inferred clobber listReid Kleckner2017-02-142-4/+13
| | | | | | | Since r295004, LLVM has started modelling this new register, but we don't have GCC constraint inline asm spellings for it yet. llvm-svn: 295107
* [profiling] Update test cases to deal with name variable change (NFC)Vedant Kumar2017-02-142-15/+7
| | | | | | | | | This is a re-try of r295085: fix up some test cases that assume that profile name variables are preserved by the instrprof pass. This catches one additional case in test/CoverageMapping/unused_names.c. llvm-svn: 295101

This is a follow-up to r281682, which fixed a bug in computeBlockInfo where the captured VarDecl's type, rather than the captured field type of the enclosing lambda or block, was used to compute the layout of a block. This commit makes similar changes to enterBlockScope. This is necessary to correctly determine whether a block capture requires cleanup. rdar://problem/30388124 llvm-svn: 295034

* Add a destruct-on-exit function to ASTContext.George Burgess IV2017-02-144-35/+16
| | | | | | | | | | | | | | It looks like the only use of AddDeallocation is to indirectly call the destructors of objects. In one case I found (TypeAliasTemplateDecl::Common), the destructor is a nop, so registering it to run later seems pointless. All of the other *::Common types have non-trivial dtors, so deleting the useless AddDeallocation felt somewhat fragile. Happy to kill it + turn the is_trivial_dtor check into a static_assert if people think that'd be better. llvm-svn: 295029

* Canonicalize implicit deduction guide parameter types when forming a deductionRichard Smith2017-02-142-9/+32
| | | | | | | | | | | | guide from a constructor. The purpose of this change is to avoid triggering instantiation of the class when substituting back into the deduction guide if it uses a typedef member. We will still instantiate the class if the constructor (explicitly or implicitly, directly or indirectly) uses the current instantiation in a way that we can't canonicalize out, but that seems unavoidable. llvm-svn: 295016

* [MS ABI] Correctly mangling vbase destructorsDavid Majnemer2017-02-149-36/+47
| | | | | | | | | | | | | They are a little bit of a special case in the mangling. They are always mangled without taking into account their virtual-ness of the destructor. They are also mangled to return void, unlike the actual destructor. This fixes PR31931. Differential Revision: https://reviews.llvm.org/D29912 llvm-svn: 295010
* [c++1z] Synthesize implicit deduction guides from constructors on demand. RankRichard Smith2017-02-1414-134/+564
| | | | | | | | | | | | | | | | | | | such guides below explicit ones, and ensure that references to the class's template parameters are not treated as forwarding references. We make a few tweaks to the wording in the current standard: 1) The constructor parameter list is copied faithfully to the deduction guide, without losing default arguments or a varargs ellipsis (which the standard wording loses by omission). 2) If the class template declares no constructors, we add a T() -> T<...> guide (which will only ever work if T has default arguments for all non-pack template parameters). 3) If the class template declares nothing that looks like a copy or move constructor, we add a T(T<...>) -> T<...> guide. #2 and #3 follow from the "pretend we had a class type with these constructors" philosophy for deduction guides. llvm-svn: 295007
* When the new expr's array size is an ICE, emit it as a constant expression.Nick Lewycky2017-02-132-1/+11
| | | | | | This bypasses integer sanitization checks which are redundant on the expression since it's been checked by Sema. Fixes a clang codegen assertion on "void test() { new int[0+1]{0}; }" when building with -fsanitize=signed-integer-overflow. llvm-svn: 295006

* [coroutines] NFC: Refactor Sema::CoroutineBodyStmt construction.Gor Nishanov2017-02-135-109/+242
| | | | | | | | | | | | | | | | | | | Summary: Sema::CheckCompletedCoroutineBody was growing unwieldy with building all of the substatements. Also, constructors for CoroutineBodyStmt had way too many parameters. Instead, CoroutineBodyStmt now defines CtorArgs structure with all of the required construction parameters. CheckCompleteCoroutineBody delegates construction of individual substatements to short functions one per each substatement. Also, added a drive-by fix of initializing CoroutinePromise to nullptr in ScopeInfo.h. And addressed the FIXME that wanted to tail allocate extra room at the end of the CoroutineBodyStmt to hold parameter move expressions. (The comment was longer that the code that implemented tail allocation).

* CodeGen: use # as the comment leader for ARC markerSaleem Abdulrasool2017-02-111-1/+1
| | | | | | | | | | Use # as the comment leader for AArch64 auto-release elision marker. This is to keep it in sync with the value used in swift. When building libdispatch for Linux AArch64, the auto-release elision marker was emitted. However, ELF uses # as the comment leader while MachO accepts both ; and #. Use the common marker for it instead. llvm-svn: 294877
* CodeGen: annotate ObjC ARC functions with ABI constraintsSaleem Abdulrasool2017-02-112-11/+36
| | | | | | | | | | | | | | | | Certain ARC runtime functions have an ABI contract of being forwarding. Annotate the functions with the appropriate `returned` attribute on the arguments. This hoists some of the runtime ABI contract information into the frontend rather than the backend transformations. The test adjustments are to mark the returned function parameter as such. The minor change to the IR output is due to the fact that the returned reference of the object causes it to extend the lifetime of the object by returning an autoreleased return value. The result is that the explicit objc_autorelease call is no longer formed, as autorelease elision is now possible on the return. llvm-svn: 294872
