* Use !hasArg with two options instead of !hasArg && !hasArg.Douglas Katzman2015-11-171-92/+52
| | | | | | Thereby fixing a warning about failure to claim all args. llvm-svn: 253372
* bmiintrin.h: Allow using the tzcnt intrinsics for non-BMI targetsHans Wennborg2015-11-171-3/+9
| | | | | | | | | | | | The tzcnt intrinsics are used non non-BMI targets by code (e.g. ffmpeg) that uses it as a potentially faster BSF. The TZCNT instruction is special in that it's encoded in a backward-compatible way and behaves as BSF on non-BMI targets. Differential Revision: http://reviews.llvm.org/D14748 llvm-svn: 253358
* ARM: fix mismatch between Clang and backend on exception type.Tim Northover2015-11-171-6/+2
| | | | | | | | | | | | "-arch armv7k" is only normally used with a watchos target, but Clang doesn't stop you from giving a "-miphoneos-version-min" option too, converting the triple to "thumbv7k-apple-ios". In this case the backend will decide to use SjLj exceptions, so Clang needs to agree so it can create the correct predefines. Fortunately, there's a handy function to make the decision for us now. llvm-svn: 253355

* Revert "Make FP_CONTRACT ON the default."Manuel Klimek2015-11-171-0/+1
| | | | | | | | | This reverts commit r253269. This leads to assert / segfault triggering on the following reduced example: float foo(float U, float base, float cell) { return (U = 2 * base) - cell; } llvm-svn: 253337

* Derive nacltools::Linker from GnuTool to get response file supportDerek Schuff2015-11-161-2/+2
| | | | | | | It could be derived from gnutools::Linker directly but this way makes it consistent with all the other toolchains around it. llvm-svn: 253259

Builtins are positive by default so don't need this change, but we pull the default list of features from the command line and so need to make sure that we only include features that are turned on for code generation in our error. llvm-svn: 253242
* [mips] Do not add arch name in the compiler-rt's components.Vasileios Kalintiris2015-11-161-2/+1
| | | | | | | Instead, use the constant "mips" since the libraries are already placed under the multilib's OS suffix. llvm-svn: 253214

* [ARM,AArch64] Fix __rev16l and __rev16ll intrinsicsOliver Stannard2015-11-161-6/+10
| | | | | | | | | | | | | | | | | | | | These two intrinsics are defined in arm_acle.h. __rev16l needs to rotate by 16 bits, bit it was actually rotating by 2 bits. For AArch64, where long is 64 bits, this would still be wrong. __rev16ll was incorrect, it reversed the bytes in each 32-bit word, rather than each 16-bit halfword. The correct implementation is to apply __rev16 to the top and bottom words of the 64-bit value. For AArch32 targets, these get compiled down to the hardware rev16 instruction at -O1 and above. For AArch64 targets, the 64-bit ones get compiled to two 32-bit rev16 instructions, because there is not currently a pattern for the 64-bit rev16 instruction.

* clang-format: Enable #include sorting by default.Daniel Jasper2015-11-161-0/+6
| | | | | | | | | This has seen quite some usage and I am not aware of any issues. Also add a style option to enable/disable include sorting. The existing command line flag can from now on be used to override whatever is set in the style. llvm-svn: 253202
* [ARM] Pass in the architecture to TargetParser to cope with API changeBradley Smith2015-11-161-2/+3
| | | | | | | | The TargetParser API to get the default FPU and default extensions has changed so that it can fall back to the architecture in case of a generic CPU. llvm-svn: 253199
* Update for the gnu flavor being renamed to old-gnu.Rafael Espindola2015-11-161-3/+3

* [CGDebugInfo] Set the size and align for reference typesKeno Fischer2015-11-161-6/+7
| | | | | | | | | | In r253186, I changed the DIBuilder API to now take size and align for reference types as well. This was done in preparation for upcoming changes to the Verifier that will validate that sizes match between DI types and IR values that are declared as having those types. This updates clang to actually pass the information through. llvm-svn: 253190
* [Sema] Implement several unary type traits more accuratelyDavid Majnemer2015-11-161-19/+32
| | | | | | | | | | | | | | is_empty, is_polymorphic, and is_abstract didn't handle incomplete types correctly. Only non-union class types must be complete for these traits. is_final and is_sealed don't care about the particular spelling of the FinalAttr. is_interface_class should always return false regardless of its input. The type trait can only be satisfied in a mode we do not support (/CLR). llvm-svn: 253184

* [analyzer] Handle calling ObjC super method from inside C++ lambda.Devin Coughlin2015-11-151-0/+17
| | | | | | | | | | When calling a ObjC method on super from inside a C++ lambda, look at the captures to find "self". This mirrors how the analyzer handles calling super in an ObjC block and fixes an assertion failure. rdar://problem/23550077 llvm-svn: 253176

* [analyzer] Refer to capture field to determine if capture is reference.Devin Coughlin2015-11-151-5/+5
| | | | | | | | | | | | | The analyzer incorrectly treats captures as references if either the original captured variable is a reference or the variable is captured by reference. This causes the analyzer to crash when capturing a reference type by copy (PR24914). Fix this by refering solely to the capture field to determine when a DeclRefExpr for a lambda capture should be treated as a reference type. https://llvm.org/bugs/show_bug.cgi?id=24914 rdar://problem/23524412 llvm-svn: 253157
* [Sema] Don't crash trying to diagnose abs called on a pointer typeDavid Majnemer2015-11-151-0/+13
| | | | | | | | | | | | | | | | | Clang tries to figure out if a call to abs is suspicious by looking through implicit casts to look at the underlying, implicitly converted type. Interestingly, C has implicit conversions from pointer-ish types like function to less exciting types like int. This trips up our 'abs' checker because it doesn't know which variant of 'abs' is appropriate. Instead, diagnose 'abs' called on function types upfront. This sort of thing is highly suspicious and is likely indicative of a missing pointer dereference/function call/array index operation. This fixes PR25532. llvm-svn: 253156

* [modules] Allow "redefinition" of typedef of anon tag from unimported submoduleBen Langmuir2015-11-142-2/+4
| | | | | | | | | r233345 started being stricter about typedef names for linkage purposes in non-visible modules, but broke languages without the ODR. rdar://23527954 llvm-svn: 253123

* CFG: Delay creating Dtors for CompoundStmts which end in ReturnStmtMatthias Gehre2015-11-141-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: VisitReturnStmt would create a new block with including Dtors, so the Dtors created in VisitCompoundStmts would be in an unreachable block. Example: struct S { ~S(); }; void f() { S s; return; } void g() { S s; } Before this patch, f has one additional unreachable block containing just the destructor of S. With this patch, both f and g have the same blocks. Reviewers: krememek Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D13973 llvm-svn: 253107

* Fix auto-link for text-based dynamic library SDKs.Juergen Ributzka2015-11-131-3/+12
| | | | | | | | | | When linking against text-based dynamic library SDKs the library name of a framework has now more than one possible filename extensions. This fix tests for both possible extensions (none, and .tbd). This fixes rdar://problem/20609975 llvm-svn: 253060
* [Sema] __is_constructible should return false for function typesDavid Majnemer2015-11-131-10/+11
| | | | | | | | While functions types are complete, they cannot be constructed. This fixes PR25513. llvm-svn: 253013

* Add support for function attribute 'disable_tail_calls'.Akira Hatanaka2015-11-132-2/+28
| | | | | | | | | | | | | | | | | | | | | | The ``disable_tail_calls`` attribute instructs the backend to not perform tail call optimization inside the marked function. For example, int callee(int); int foo(int a) __attribute__((disable_tail_calls)) { return callee(a); // This call is not tail-call optimized. } Note that this attribute is different from 'not_tail_called', which prevents tail-call optimization to the marked function. rdar://problem/8973573 Differential Revision: http://reviews.llvm.org/D12547 llvm-svn: 252986
