* [InstCombine] Move SSE/AVX vector blend folding to instcombinerSimon Pilgrim2015-08-126-245/+113
| | | | | | | | | | | | As discussed in D11886, this patch moves the SSE/AVX vector blend folding to instcombiner from PerformINTRINSIC_WO_CHAINCombine (which allows us to remove this completely). InstCombiner already had partial support for this, I just had to add support for zero (ConstantAggregateZero) masks and also the case where both selection inputs were the same (allowing us to ignore the mask). I also moved all the relevant combine tests into InstCombine/blend_x86.ll Differential Revision: http://reviews.llvm.org/D11934 llvm-svn: 244723

* PseudoSourceValue: Transform the mips subclass to target independent subclassesAlex Lorenz2015-08-114-83/+102
| | | | | | | | | | | | This commit transforms the mips-specific 'MipsCallEntry' subclass of the 'PseudoSourceValue' class into two, target-independent subclasses named 'GlobalValuePseudoSourceValue' and 'ExternalSymbolPseudoSourceValue'. This change makes it easier to serialize the pseudo source values by removing target-specific pseudo source values. Reviewers: Akira Hatanaka llvm-svn: 244698
* PseudoSourceValue: Replace global manager with a manager in a machine function.Alex Lorenz2015-08-1151-558/+602
| | | | | | | | | | | | | | | | | | | | | | 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.

* PseudoSourceValue: Introduce a 'PSVKind' enumerator.Alex Lorenz2015-08-113-25/+37
| | | | | | | | | | | | | | This commit introduces a new enumerator named 'PSVKind' in the 'PseudoSourceValue' class. This enumerator is now used to distinguish between the various kinds of pseudo source values. This change is done in preparation for the changes to the pseudo source value object management and to the PseudoSourceValue's class hierarchy - the next two PseudoSourceValue commits will get rid of the global variable that manages the pseudo source values and the mips specific MipsCallEntry subclass.

* PseudoSourceValue: Update comments and fix lowercase variable names. NFC.Alex Lorenz2015-08-112-28/+23
| | | | | | | | | | | This commit updates the documentation comments in PseudoSourceValue.cpp and PseudoSourceValue.h based on the LLVM's documentation style. It also fixes several instances of variable names that started with a lowercase letter.

* Use 32-bit divides instead of 64-bit divides where possible.Mark Heffernan2015-08-112-0/+84
| | | | | | | | | For NVPTX, try to use 32-bit division instead of 64-bit division when the dividend and divisor fit in 32 bits. This speeds up some internal benchmarks significantly. The underlying reason is that many index computations are carried out in 64-bits but never actually exceed the capacity of a 32-bit word. llvm-svn: 244684
* Make DW_AT_[MIPS_]linkage_name optional, and off by default for SCE.Paul Robinson2015-08-1117-25/+116
| | | | | | | | | | | | | | Mangled "linkage" names can be huge, and if the debugger (or other tools) have no use for them, the size savings can be very impressive (on the order of 40%). Add one test for controlling behavior, and modify a number of tests to either stop using linkage names, or make llc emit them (so these tests will still run when the default triple is for PS4).

This only happens when Aggressive is true, otherwise hasOneUse() check already prevents from folding the multiplication with more uses.

* [LowerSwitch] Fix a bug when LowerSwitch deletes the default blockChen Li2015-08-112-5/+37
| | | | | | | | | | | | Summary: LowerSwitch crashed with the attached test case after deleting the default block. This happened because the current implementation of deleting dead blocks is wrong. After the default block being deleted, it contains no instruction or terminator, and it should no be traversed anymore. However, since the iterator is advanced before processSwitchInst() function is executed, the block advanced to could be deleted inside processSwitchInst(). The deleted block would then be visited next and crash dyn_cast<SwitchInst>(Cur->getTerminator()) because Cur->getTerminator() returns a nullptr. This patch fixes this problem by recording dead default blocks into a list, and delete them after all processSwitchInst() has been done. It still possible to visit dead default blocks and waste time process them. But it is a compile time issue, and I plan to have another patch to add support to skip dead blocks.

* [GlobalMerge] Use private linkage for MergedGlobals variablesJohn Brawn2015-08-1111-91/+62
| | | | | | | | | | | | | | | Other objects can never reference the MergedGlobals symbol so external linkage is never needed. Using private instead of internal linkage means the object is more similar to what it looks like when global merging is not enabled, with the only difference being that the merged variables are addressed indirectly relative to the start of the section they are in. Also add aliases for merged variables with internal linkage, as this also makes the object be more like what it is when they are not merged.

The non-inbound GEP is folded here because the DataLayout is no longer optional, the fold was originally guarded with a comment that said: We need TD information to know the pointer size unless this is inbounds. Now we always have "TD information" and perform the fold. Thanks Jonathan Roelofs for noticing. From: Mehdi Amini <mehdi.amini@apple.com> llvm-svn: 244613

| | | | | | | | | | | | | | | Summary: Check the contents of BBtoRegion during analysis verification. It only takes place if -verify-region-info is passed or LLVM is compiled with XDEBUG. RegionBase<Tr>::verifyRegion() also checks the RegionInfoBase<Tr>::VerifyRegionInfo flag, which is redundant, but verifyRegion() is public API and might be invoked from other sites. In order to avoid behavioral change, this check is not removed. In any case, no region will be verified unless VerifyRegionInfo is set.
