* [SystemZ] Fix assertion failure in tryBuildVectorShuffleUlrich Weigand2015-09-151-1/+1
| | | | | | | | | | | Under certain circumstances, tryBuildVectorShuffle would attempt to create a BUILD_VECTOR node with an invalid combination of types. This happened when one of the components of the original BUILD_VECTOR was itself a TRUNCATE node. That TRUNCATE was stripped off during intermediate processing to simplify code, but when adding the node back to the result vector, we still need it to get the type right. llvm-svn: 247694
* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-156-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change. Thanks go to Pavel Labath for fixing LLDB for me.

* Save LaneMask with livein registersMatthias Braun2015-09-091-3/+2
| | | | | | | | | | | | | | | | | With subregister liveness enabled we can detect the case where only parts of a register are live in, this is expressed as a 32bit lanemask. The current code only keeps registers in the live-in list and therefore enumerated all subregisters affected by the lanemask. This turned out to be too conservative as the subregister may also cover additional parts of the lanemask which are not live. Expressing a given lanemask by enumerating a minimum set of subregisters is computationally expensive so the best solution is to simply change the live-in list to store the lanemasks as well. This will reduce memory usage for targets using subregister liveness and slightly increase it for other targets Differential Revision: http://reviews.llvm.org/D12442 llvm-svn: 247171
* [DAGCombiner] Attempt to mask vectors before zero extension instead of after.Simon Pilgrim2015-08-151-3/+19
| | | | | | | | | | | | | | For cases where we TRUNCATE and then ZERO_EXTEND to a larger size (often from vector legalization), see if we can mask the source data and then ZERO_EXTEND (instead of after a ANY_EXTEND). This can help avoid having to generate a larger mask, and possibly applying it to several sub-vectors. (zext (truncate x)) -> (zext (and(x, m)) Includes a minor patch to SystemZ to better recognise 8/16-bit zero extension patterns from RISBG bit-extraction code. This is the first of a number of minor patches to help improve the conversion of byte masks to clear mask shuffles. Differential Revision: http://reviews.llvm.org/D11764 llvm-svn: 245160

* [SystemZ] Support large LLVM IR struct return valuesUlrich Weigand2015-08-133-4/+18
| | | | | | | | | | | | | | | | | | | | | | | Recent mesa/llvmpipe crashes on SystemZ due to a failed assertion when attempting to compile a routine with a return type of { <4 x float>, <4 x float>, <4 x float>, <4 x float> } on a system without vector instruction support. This is because after legalizing the vector type, we get a return value consisting of 16 floats, which cannot all be returned in registers. Usually, what should happen in this case is that the target's CanLowerReturn routine rejects the return type, in which case SelectionDAG falls back to implementing a structure return in memory via implicit reference. However, the SystemZ target never actually implemented any CanLowerReturn routine, and thus would accept any struct return type. This patch fixes the crash by implementing CanLowerReturn. As a side effect, this also handles fp128 return values, fixing a todo that was noted in SystemZCallingConv.td. llvm-svn: 244889
* PseudoSourceValue: Replace global manager with a manager in a machine function.Alex Lorenz2015-08-112-27/+29
| | | | | | | | | | | | | | | | | | | | | | This commit removes the global manager variable which is responsible for storing and allocating pseudo source values and instead it introduces a new manager class named 'PseudoSourceValueManager'. Machine functions now own an instance of the pseudo source value manager class. This commit also modifies the 'get...' methods in the 'MachinePointerInfo' class to construct pseudo source values using the instance of the pseudo source value manager object from the machine function. This commit updates calls to the 'get...' methods from the 'MachinePointerInfo' class in a lot of different files because those calls now need to pass in a reference to a machine function to those methods. This change will make it easier to serialize pseudo source values as it will enable me to transform the mips specific MipsCallEntry PseudoSourceValue subclass into two target independent subclasses.

* [TTI] Make the cost APIs in TargetTransformInfo consistently use 'int'Chandler Carruth2015-08-052-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | rather than 'unsigned' for their costs. For something like costs in particular there is a natural "negative" value, that of savings or saved cost. As a consequence, there is a lot of code that subtracts or creates negative values based on cost, all of which is prone to awkwardness or bugs when dealing with an unsigned type. Similarly, we *never* want these values to wrap, as that would cause Very Bad code generation (likely percieved as an infinite loop as we try to emit over 2^32 instructions or some such insanity). All around 'int' seems a much better fit for these basic metrics. I've added asserts to ensure that at least the TTI interface never returns negative numbers here. If we ever have a use case for negative numbers, we can remove this, but this way a bug where someone used '-1' to produce a 'very large' cost will be caught by the assert. This passes all tests, and is also UBSan clean. No functional change intended. Differential Revision: http://reviews.llvm.org/D11741 llvm-svn: 244080

* Implement target independent TLS compatible with glibc's emutls.c.Chih-Hung Hsieh2015-07-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 'common' section TLS is not implemented. Current C/C++ TLS variables are not placed in common section. DWARF debug info to get the address of TLS variables is not generated yet. clang and driver changes in http://reviews.llvm.org/D10524 Added -femulated-tls flag to select the emulated TLS model, which will be used for old targets like Android that do not support ELF TLS models. Added TargetLowering::LowerToTLSEmulatedModel as a target-independent function to convert a SDNode of TLS variable address to a function call to __emutls_get_address. Added into lib/Target/*/*ISelLowering.cpp to call LowerToTLSEmulatedModel for TLSModel::Emulated. Although all targets supporting ELF TLS models are enhanced, emulated TLS model has been tested only for Android ELF targets. Modified AsmPrinter.cpp to print the emutls_v.* and emutls_t.* variables for emulated TLS variables. Modified DwarfCompileUnit.cpp to skip some DIE for emulated TLS variabls. TODO: Add proper DIE for emulated TLS variables. Added new unit tests with emulated TLS. Differential Revision: http://reviews.llvm.org/D10522 llvm-svn: 243438

* MC: Remove MCSubtargetInfo() default constructorDuncan P. N. Exon Smith2015-07-101-3/+1
| | | | | | | | | | | | | | | | | | | | | Force all creators of `MCSubtargetInfo` to immediately initialize it, merging the default constructor and the initializer into an initializing constructor. Besides cleaning up the code a little, this makes it clear that the initializer is never called again later. Out-of-tree backends need a trivial change: instead of calling: auto *X = new MCSubtargetInfo(); InitXYZMCSubtargetInfo(X, ...); return X; they should call: return createXYZMCSubtargetInfoImpl(...); There's no real functionality change here. llvm-svn: 241957
* Target RegisterInfo: devirtualize TargetFrameLoweringJF Bastien2015-07-101-3/+3
| | | | | | | | | | | | | Summary: The target frame lowering's concrete type is always known in RegisterInfo, yet it's only sometimes devirtualized through a static_cast. This change adds an auto-generated static function <Target>GenRegisterInfo::getFrameLowering(const MachineFunction &MF) which does this devirtualization, and uses this function in all targets which can. This change was suggested by sunfish in D11070 for WebAssembly, I figure that I may as well improve the other targets while I'm here.

| | | | | | | | | | | | | | | | | | | | Summary: This concludes the patch series to eliminate StringRef forms of GNU triples from the internals of LLVM that began in r239036. At this point, the StringRef-form of GNU Triples should only be used in the public API (including IR serialization) and a couple objects that directly interact with the API (most notably the Module class). The next step is to replace these Triple objects with the TargetTuple object that will represent our authoratative/unambiguous internal equivalent to GNU Triples.

* [SystemZ] Only attempt RxSBG optimization for integer typesUlrich Weigand2015-06-251-2/+7
| | | | | | | | | | | | As pointed out by Justin Bogner (see r240520), SystemZDAGToDAGISel::Select currently attempts to convert boolean operations into RxSBG even on some non-integer types (in particular, vector types).
