* Move most user of TargetMachine::getDataLayout to the Module oneMehdi Amini2015-07-161-1/+2
| | | | | | | | | | | | | | | | | | | | | Summary: This change is part of a series of commits dedicated to have a single DataLayout during compilation by using always the one owned by the module. This patch is quite boring overall, except for some uglyness in ASMPrinter which has a getDataLayout function but has some clients that use it without a Module (llmv-dsymutil, llvm-dwarfdump), so some methods are taking a DataLayout as parameter.

* MachineRegisterInfo: Remove UsedPhysReg infrastructureMatthias Braun2015-07-141-2/+2
| | | | | | | | | | | | | We have a detailed def/use lists for every physical register in MachineRegisterInfo anyway, so there is little use in maintaining an additional bitset of which ones are used. Removing it frees us from extra book keeping. This simplifies VirtRegMap. Differential Revision: http://reviews.llvm.org/D10911 llvm-svn: 242173
* PrologEpilogInserter: Rewrite API to determine callee save regsiters.Matthias Braun2015-07-142-6/+7
| | | | | | | | | | | | | | | | This changes TargetFrameLowering::processFunctionBeforeCalleeSavedScan(): - Rename the function to determineCalleeSaves() - Pass a bitset of callee saved registers by reference, thus avoiding the function-global PhysRegUsed bitset in MachineRegisterInfo. - Without PhysRegUsed the implementation is fine tuned to not save physcial registers which are only read but never modified.

* 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 Bastien2015-07-101-2/+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.

* Change the last few internal StringRef triples into Triple objects.Daniel Sanders2015-07-061-2/+3
| | | | | | | | | | | | | | | | | | | | 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.

* [TargetLowering] StringRefize asm constraint getters.Benjamin Kramer2015-07-052-6/+4

* Hexagon: Paper over the undefined behaviour introduced by r238692Justin Bogner2015-06-242-1/+3
| | | | | | | | | | | | | | | | This stops shifting a 32-bit value by such absurd amounts as 96 and 120. We do this by dropping a call to the function that was doing this entirely, which rather surprisingly doesn't break *any* tests. I've also added an assert in the misbehaving function to prove that it's no longer being called with completely invalid arguments. This change looks pretty bogus and we should probably be reverting r238692 instead, but this is hard to do with the number of follow ups that have happened since. It can't be any worse than the undefined behaviour that was happening before though. llvm-svn: 240526

* Remove DisableTailCalls from TargetOptions and the code in resetTargetOptionsAkira Hatanaka2015-06-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | that was resetting it. Remove the uses of DisableTailCalls in subclasses of TargetLowering and use the value of function attribute "disable-tail-calls" instead. Also, unconditionally add pass TailCallElim to the pipeline and check the function attribute at the start of runOnFunction to disable the pass on a per-function basis. This is part of the work to remove TargetMachine::resetTargetOptions, and since DisableTailCalls was the last non-fast-math option that was being reset in that function, we should be able to remove the function entirely after the work to propagate IR-level fast-math flags to DAG nodes is completed. Out-of-tree users should remove the uses of DisableTailCalls and make changes to attach attribute "disable-tail-calls"="true" or "false" to the functions in the IR. rdar://problem/13752163 Differential Revision: http://reviews.llvm.org/D10099 llvm-svn: 239427
