* [EarlyCSE] Add option to use MemorySSA for function simplification run of ↵Geoff Berry2017-06-102-2/+10
| | | | | | | | | | | | | | | | EarlyCSE (off by default). Summary: Use MemorySSA for memory dependency checking in the EarlyCSE pass at the start of the function simplification portion of the pipeline. We rely on the fact that GVNHoist runs just after this pass of EarlyCSE to amortize the MemorySSA construction cost since GVNHoist uses MemorySSA and EarlyCSE preserves it. This is turned off by default. A follow-up change will turn it on to allow for easier reversion in case it breaks something. llvm-svn: 305146

| | | | | | | | | | | | For the case when LLVM_OPTIMIZED_TABLEGEN is ON (enables LLVM_USE_HOST_TOOLS), we need both _TABLEGEN_TARGET and _TABLEGEN_EXE in the DEPENDS list to have .inc files rebuilt on a tablegen change, as cmake does not propagate file-level dependencies of custom targets. We could always have just one dependency on both the target and the file, but the 2 cases would produce cleaner cmake files. llvm-svn: 305142

| | | | | | | | | | | | | | | Currently there is a bug in SROA::presplitLoadsAndStores which causes assertion in GEPOperator::accumulateConstantOffset.

| | | | | | | | | | | | | | | | | | Summary: isSafeToSpeculativelyExecute is the wrong predicate to use here. All that checks for is whether it is safe to hoist a value due to unaligned/un-dereferencable accesses. However, not only are we doing sinking rather than hoisting, our concern is that the location we're loading from may have been modified. Instead forbid sinking any load across a critical edge.

This patch moves the complex code into an else so we only do it when we are handling a predicate other than EQ/NE.

* SelectionDAG: Remove deleted nodes from legalized set to avoid clash with ↵Zvi Rackover2017-06-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | newly created nodes Summary: During DAG legalization loop in SelectionDAG::Legalize(), bookkeeping of the SDNodes that were already legalized is implemented with SmallPtrSet (LegalizedNodes). This kind of set stores only pointers to objects, not the objects themselves. Unfortunately, if SDNode is deleted during legalization for some reason, LegalizedNodes set is not informed about this fact. This wouldn’t be so bad, if SelectionDAG wouldn’t reuse space deallocated after deletion of unused nodes, for creation of new ones. Because of this, new nodes, created during legalization often can have pointers identical to ones that have been previously legalized, added to the LegalizedNodes set, and deleted afterwards. This in turn causes, that newly created nodes, sharing the same pointer as deleted old ones, are present in LegalizedNodes *already at the moment of creation*, so we never call Legalize on them. The fix facilitates the fact, that DAG notifies listeners about each modification. I have registered DAGNodeDeletedListener inside SelectionDAG::Legalize, with a callback function that removes any pointer of any deleted SDNode from the LegalizedNodes set. With this modification, LegalizeNodes set does not contain pointers to nodes that were deleted, so newly created nodes can always be inserted to it, even if they share pointers with old deleted nodes. Patch by pawel.szczerbuk@intel.com The issue this patch addresses causes failures in an out-of-tree target, and i was not able to create a reproducer for an in-tree target, hence there is no test-case.

* Reland "[SelectionDAG] Enable target specific vector scalarization of calls ↵Simon Dardis2017-06-0915-105/+2117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and returns" By target hookifying getRegisterType, getNumRegisters, getVectorBreakdown, backends can request that LLVM to scalarize vector types for calls and returns. The MIPS vector ABI requires that vector arguments and returns are passed in integer registers. With SelectionDAG's new hooks, the MIPS backend can now handle LLVM-IR with vector types in calls and returns. E.g. 'call @foo(<4 x i32> %4)'. Previously these cases would be scalarized for the MIPS O32/N32/N64 ABI for calls and returns if vector types were not legal. If vector types were legal, a single 128bit vector argument would be assigned to a single 32 bit / 64 bit integer register. By teaching the MIPS backend to inspect the original types, it can now implement the MIPS vector ABI which requires a particular method of scalarizing vectors. Previously, the MIPS backend relied on clang to scalarize types such as "call @foo(<4 x float> %a) into "call @foo(i32 inreg %1, i32 inreg %2, i32 inreg %3, i32 inreg %4)". This patch enables the MIPS backend to take either form for vector types. The previous version of this patch had a "conditional move or jump depends on uninitialized value".
