* Correct hasFeature/isValidFeatureName's handling of shstk/adx/mwaitxErich Keane2017-12-211-2/+7
| | | | | | | | | | | | https://bugs.llvm.org/show_bug.cgi?id=35721 reports that x86intrin.h is issuing a few warnings. This is because attribute target is using isValidFeatureName for its source. It was also discovered that two of these were missing from hasFeature. Additionally, shstk is and ibu are reordered alphabetically, as came up during code review. llvm-svn: 321324
* [AARch64] Add ARMv8.2-A FP16 vector intrinsicsAbderrazek Zaafrani2017-12-211-0/+3

* Remove llvm::MemoryBuffer const_castsPavel Labath2017-12-201-3/+4
| | | | | | | | | | | | | | | Summary: llvm has grown a WritableMemoryBuffer class, which is convertible (inherits from) a MemoryBuffer. We can use it to avoid conts_casting the buffer contents when we want to write to it.

* [c++20] P0515R3: Parsing support and basic AST construction for operator <=>.Richard Smith2017-12-141-0/+1
| | | | | | | | | | | | | | | Adding the new enumerator forced a bunch more changes into this patch than I would have liked. The -Wtautological-compare warning was extended to properly check the new comparison operator, clang-format needed updating because it uses precedence levels as weights for determining where to break lines (and several operators increased their precedence levels with this change), thread-safety analysis needed changes to build its own IL properly for the new operator. All "real" semantic checking for this operator has been deferred to a future patch. For now, we use the relational comparison rules and arbitrarily give the builtin form of the operator a return type of 'void'. llvm-svn: 320707

* [CodeGen][X86] Fix handling of __fp16 vectors.Akira Hatanaka2017-12-093-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes a bug in IRGen where it generates completely broken code for __fp16 vectors on X86. For example when the following code is compiled: half4 hv0, hv1, hv2; // these are vectors of __fp16. void foo221() { hv0 = hv1 + hv2; } clang generates the following IR, in which two i16 vectors are added: @hv1 = common global <4 x i16> zeroinitializer, align 8 @hv2 = common global <4 x i16> zeroinitializer, align 8 @hv0 = common global <4 x i16> zeroinitializer, align 8 define void @foo221() { %0 = load <4 x i16>, <4 x i16>* @hv1, align 8 %1 = load <4 x i16>, <4 x i16>* @hv2, align 8 %add = add <4 x i16> %0, %1 store <4 x i16> %add, <4 x i16>* @hv0, align 8 ret void } To fix the bug, this commit uses the code committed in r314056, which modified clang to promote and truncate __fp16 vectors to and from float vectors in the AST. It also fixes another IRGen bug where a short value is assigned to an __fp16 variable without any integer-to-floating-point conversion, as shown in the following example: __fp16 a; short b; void foo1() { a = b; } @b = common global i16 0, align 2 @a = common global i16 0, align 2 define void @foo1() #0 { %0 = load i16, i16* @b, align 2 store i16 %0, i16* @a, align 2 ret void } rdar://problem/20625184 Differential Revision: https://reviews.llvm.org/D40112 llvm-svn: 320215

* Control-Flow Enforcement Technology - Shadow Stack and Indirect Branch ↵Oren Ben Simhon2017-11-262-0/+10
| | | | | | | | | | | | | | | | | | Tracking support (Clang side) Shadow stack solution introduces a new stack for return addresses only. The stack has a Shadow Stack Pointer (SSP) that points to the last address to which we expect to return. If we return to a different address an exception is triggered. This patch includes shadow stack intrinsics as well as the corresponding CET header. It includes CET clang flags for shadow stack and Indirect Branch Tracking.

* [OpenMP] Show error if VLAs are not supportedJonas Hahnfeld2017-11-183-0/+3
| | | | | | | | | | | | | | Some target devices (e.g. Nvidia GPUs) don't support dynamic stack allocation and hence no VLAs. Print errors with description instead of failing in the backend or generating code that doesn't work. This patch handles explicit uses of VLAs (local variable in target or declare target region) or implicitly generated (private) VLAs for reductions on VLAs or on array sections with non-constant size.

* [VirtualFileSystem] Support creating directories then adding files insideBen Hamilton2017-11-161-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: In https://reviews.llvm.org/D39572 , I added support for specifying `Type` when invoking `InMemoryFileSystem::addFile()`. However, I didn't account for the fact that when `Type` is `directory_file`, we need to construct an `InMemoryDirectory`, not an `InMemoryFile`, or else clients cannot create files inside that directory.
