* [opaque pointer type] Fix a few uses of PointerType::getElementType in favor ↵David Blaikie2015-09-144-12/+10
| | | | | | | | | | of uses of types already available elsewhere These are a few cleanups I happened to have from trying to go in a different direction recently, so just flushing them out while I have them. llvm-svn: 247593
* Revert "[opaque pointer type] update for LLVM API change"David Blaikie2015-09-145-10/+11
| | | | | | | | | | This was the wrong direction to take anyway (because ultimately the GlobalValue needed the pointee type again and /it/ used PointerType::getElementType eventually anyway)... let's go a different way. This reverts commit r236161. llvm-svn: 247586
* [CodeGen] Remove wrapper-free always_inline functions from COMDATsDavid Majnemer2015-09-121-1/+5
| | | | | | always_inline functions without a wrapper don't need to be in a COMDAT. llvm-svn: 247500
* Always_inline codegen rewrite.Evgeniy Stepanov2015-09-126-11/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementation may end up emitting an undefined reference for an "inline __attribute__((always_inline))" function by generating an "available_externally alwaysinline" IR function for it and then failing to inline all the calls. This happens when a call to such function is in dead code. As the inliner is an SCC pass, it does not process dead code. Libc++ relies on the compiler never emitting such undefined reference. With this patch, we emit a pair of 1. internal alwaysinline definition (called F.alwaysinline) 2a. A stub F() { musttail call F.alwaysinline } -- or, depending on the linkage -- 2b. A declaration of F. The frontend ensures that F.inlinefunction is only used for direct calls, and the stub is used for everything else (taking the address of the function, really). Declaration (2b) is emitted in the case when "inline" is meant for inlining only (like __gnu_inline__ and some other cases). This approach, among other nice properties, ensures that alwaysinline functions are always internal, making it impossible for a direct call to such function to produce an undefined symbol reference. This patch is based on ideas by Chandler Carruth and Richard Smith. llvm-svn: 247494

| | | | | | | | | | | | -force-align-stack. Also, make changes to the driver so that -mno-stack-realign is no longer an option exposed to the end-user that disallows stack realignment in the backend. Differential Revision: http://reviews.llvm.org/D11815 llvm-svn: 247451

| | | | | | | | | clang modules, if -dwarf-ext-refs (DebugTypesExtRefs) is specified. This reimplements r247369 in about a third of the amount of code. Thanks to David Blaikie pointing this out in post-commit review! llvm-svn: 247432

* [CodeGen] Teach SimplifyPersonality about the updated LandingPadInstVedant Kumar2015-09-111-28/+38
| | | | | | | | | | | | | | | When uses of personality functions were moved from LandingPadInst to Function, we forgot to update SimplifyPersonality(). This patch corrects that. Note: SimplifyPersonality() is an optimization which replaces personality functions with the default C++ personality when possible. Without this update, some ObjC++ projects fail to link against C++ libraries (seeing as the exception ABI had effectively changed). rdar://problem/22155434 llvm-svn: 247421
* [OPENMP] Preserve alignment of the original variables for the captured ↵Alexey Bataev2015-09-113-9/+25

* [SEH] Use cleanupendpad so that WinEHPrepare gets the coloring rightReid Kleckner2015-09-104-31/+55
| | | | | | | Cleanupendpad is a lot like catchendpad, so we can reuse the same EHScopeStack type. llvm-svn: 247349
* [MS ABI] Make member pointers return true for isIncompleteTypeDavid Majnemer2015-09-105-21/+5
| | | | | | | The type of a member pointer is incomplete if it has no inheritance model. This lets us reuse more general logic already embedded in clang. llvm-svn: 247346

* [OPENMP] Outlined function for parallel and other regions with list of ↵Alexey Bataev2015-09-105-62/+178
| | | | | | | | | captured variables. Currently all variables used in OpenMP regions are captured into a record and passed to outlined functions in this record. It may result in some poor performance because of too complex analysis later in optimization passes. Patch makes to emit outlined functions for parallel-based regions with a list of captured variables. It reduces code for 2*n GEPs, stores and loads at least. Codegen for task-based regions remains unchanged because runtime requires that all captured variables are passed in captured record. llvm-svn: 247251
* CFI: Introduce -fsanitize=cfi-icall flag.Peter Collingbourne2015-09-104-27/+61
| | | | | | | | | | This flag causes the compiler to emit bit set entries for functions as well as runtime bitset checks at indirect call sites. Depends on the new function bitset mechanism. Differential Revision: http://reviews.llvm.org/D11857 llvm-svn: 247238

* [MS ABI] Don't crash on references to pointers to members in argsDavid Majnemer2015-09-091-2/+2
| | | | | | | | | | | | | We know that a reference can always be dereferenced. However, we don't always know the number of bytes if the reference's pointee type is incomplete. This case was correctly handled but we didn't consider the case where the type is complete but we cannot calculate its size for ABI specific reasons. In this specific case, a member pointer's size is available only under certain conditions. This fixes PR24703. llvm-svn: 247188

* Introduce __builtin_nontemporal_store and __builtin_nontemporal_load.Michael Zolotukhin2015-09-084-6/+54
| | | | | | | | | | | | | Summary: Currently clang provides no general way to generate nontemporal loads/stores. There are some architecture specific builtins for doing so (e.g. in x86), but there is no way to generate non-temporal store on, e.g. AArch64. This patch adds generic builtins which are expanded to a simple store with '!nontemporal' attribute in IR. Differential Revision: http://reviews.llvm.org/D12313 llvm-svn: 247104
* CodeGen: Introduce CodeGenModule::CreateMetadataIdentifierForType.Peter Collingbourne2015-09-082-0/+30
| | | | | | | | | This function can be used to create a metadata identifier for a specific type. No functionality change, but this will be used by D11857 and D12026. Differential Revision: http://reviews.llvm.org/D12038 llvm-svn: 247098

* Module Debugging: Emit debug type information into clang ObjC modules.Adrian Prantl2015-09-083-3/+97
| | | | | | | | | | When -fmodule-format is set to "obj", emit debug info for all types declared in a module or referenced by a declaration into the module's object file container. This patch adds support for Objective-C types and methods. llvm-svn: 247068
