* [WebAssembly] Fix unwind destination mismatches in CFG stackifyHeejin Ahn2019-03-302-19/+516
| | | | | | | | | | | | | | | | | | | Summary: Linearing the control flow by placing `try`/`end_try` markers can create mismatches in unwind destinations. This patch resolves these mismatches by wrapping those instructions with an incorrect unwind destination with a nested `try`/`catch`/`end_try` and branching to the right destination within the new catch block.

* [RISCV] Add DAGCombine for (SplitF64 (ConstantFP x))Alex Bradbury2019-03-301-0/+11
| | | | | | | | | | | | The SplitF64 node is used on RV32D to convert an f64 directly to a pair of i32 (necessary as bitcasting to i64 isn't legal). When performed on a ConstantFP, this will result in a FP load from the constant pool followed by a store to the stack and two integer loads from the stack (necessary as there is no way to directly move between f64 FPRs and i32 GPRs on RV32D). It's always cheaper to just materialise integers for the lo and hi parts of the FP constant, so do that instead. llvm-svn: 357341
* Adds `-ftime-trace` option to clang that produces Chrome `chrome://tracing` ↵Anton Afanasyev2019-03-303-0/+197
| | | | | | | | | | | | | | compatible JSON profiling output dumps. This change adds hierarchical "time trace" profiling blocks that can be visualized in Chrome, in a "flame chart" style. Each profiling block can have a "detail" string that for example indicates the file being processed, template name being instantiated, function being optimized etc. This is taken from GitHub PR: https://github.com/aras-p/llvm-project-20170507/pull/2 Patch by Aras Pranckevičius.

* [WebAssembly] Optimize the number of routing blocks in FixIrreducibleCFGHeejin Ahn2019-03-301-17/+62
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently we create a routing block to the dispatch block for every predecessor of every entry. So the total number of routing blocks created will be (# of preds) * (# of entries). But we don't need to do this: we need at most 2 routing blocks per loop entry, one for when the predecessor is inside the loop and one for it is outside the loop. (We can't merge these into one because this will creates another loop cycle between blocks inside and blocks outside) This patch fixes this and creates at most 2 routing blocks per entry. This also renames variable `Split` to `Routing`, which I think is a bit clearer.

* AMDGPU: Remove dx10-clamp from subtarget featuresMatt Arsenault2019-03-2911-30/+94
| | | | | | | | | | | | | | | | | | Since this can be set with s_setreg*, it should not be a subtarget property. Set a default based on the calling convention, and Introduce a new amdgpu-dx10-clamp attribute to override this if desired. Also introduce a new amdgpu-ieee attribute to match. The values need to match to allow inlining. I think it is OK for the caller's dx10-clamp attribute to override the callee, but there doesn't appear to be the infrastructure to do this currently without definining the attribute in the generic Attributes.td. Eventually the calling convention lowering will need to insert a mode switch somewhere for these. llvm-svn: 357302

* [DAG] Set up infrastructure to avoid smart constructor-based dangling nodesNirav Dave2019-03-292-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: Various SelectionDAG non-combine operations (e.g. the getNode smart constructor and legalization) may leave dangling nodes by applying optimizations without fully pruning unused result values. This results in nodes that are never added to the worklist and therefore can not be pruned. Add a node inserter for the combiner to make sure such nodes have the chance of being pruned. This allows a number of additional peephole optimizations.

| | | | | | | | | | For the cases where the icmp/fcmp predicate is commutative, use reorderInputsAccordingToOpcode to collect and commute the operands. This requires a helper to recognise commutativity in both general Instruction and CmpInstr types - the CmpInst::isCommutative doesn't overload the Instruction::isCommutative method for reasons I'm not clear on (maybe because its based on predicate not opcode?!?).

* [mips] Fix lowering a signed immediate for *.d MSA instructionsSimon Atanasyan2019-03-291-1/+2
| | | | | | | | | | | | | | | The `lowerMSASplatImm` function zero-extends `i32` immediates while building constant. If target type is `i64`, negative immediate loses the sign. As a result, for example `__builtin_msa_ldi_d(-1)` lowered to series of instruction loads incorrect value 0xffffffff to the `$w0` register instead of single `ldi.d $w0, -1` instruction. The fix zero-extends unsigned immediates and signed-extend signed immediates. Differential Revision: http://reviews.llvm.org/D59884 llvm-svn: 357264

* [DAGCombiner] simplify shuffle of shuffleSanjay Patel2019-03-291-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | After investigating the examples from D59777 targeting an SSE4.1 machine, it looks like a very different problem due to how we map illegal types (256-bit in these cases). We're missing a shuffle simplification that maps elements of a vector back to a shuffled operand. We have a more general version of this transform in DAGCombiner::visitVECTOR_SHUFFLE(), but that generality means it is limited to patterns with a one-use constraint, and the examples here have 2 uses. We don't need any uses or legality limitations for a simplification (no new value is created). It looks like we miss this pattern in IR too. In one of the zext examples here, we have shuffle masks like this: Shuf0 = vector_shuffle<0,u,3,7,0,u,3,7> Shuf = vector_shuffle<4,u,6,7,u,u,u,u> ...so that's moving the high half of the 1st vector into the low half. But the high half of the 1st vector is already identical to the low half. Differential Revision: https://reviews.llvm.org/D59961 llvm-svn: 357258

| | | | | | | | | | | | | | | | | | | | | | | This is a sibling to rL357178 that I noticed we'd hit if we chose an alternate transform in D59818. %z = zext i8 %x to i32 %dec = add i32 %z, -1 %r = sext i32 %dec to i64 => %z2 = zext i8 %x to i64 %r = add i64 %z2, -1 https://rise4fun.com/Alive/kPP The x86 vector diffs show a slight regression, so there's a chance that we should limit this and the previous transform to scalars. But given that we allowed vectors before, I'm matching that behavior here. We should change both transforms together if that's the right thing to do. llvm-svn: 357254

* [MCA] Add an experimental MicroOpQueue stage.Andrea Di Biagio2019-03-293-0/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an experimental stage named MicroOpQueueStage. MicroOpQueueStage can be used to simulate a hardware micro-op queue (basically, a decoupling queue between 'decode' and 'dispatch'). Users can specify a queue size, as well as a optional MaxIPC (which - in the absence of a "Decoders" stage - can be used to simulate a different throughput from the decoders). This stage is added to the default pipeline between the EntryStage and the DispatchStage only if PipelineOption::MicroOpQueue is different than zero. By default, llvm-mca sets PipelineOption::MicroOpQueue to the value of hidden flag -micro-op-queue-size. Throughput from the decoder can be simulated via another hidden flag named -decoder-throughput. That flag allows us to quickly experiment with different frontend throughputs. For targets that declare a loop buffer, flag -decoder-throughput allows users to do multiple runs, each time simulating a different throughput from the decoders. This stage can/will be extended in future. For example, we could add a "buffer full" event to notify bottlenecks caused by backpressure. flag -decoder-throughput would probably go away if in future we delegate to another stage (DecoderStage?) the simulation of a (potentially variable) throughput from the decoders. For now, flag -decoder-throughput is "good enough" to run some simple experiments. Differential Revision: https://reviews.llvm.org/D59928 llvm-svn: 357248

Because the cycle or latency of multiply is not huge, we only consider such following worthy patterns. ``` (mul x, 2^N + 1) => (add (shl x, N), x) (mul x, -(2^N + 1)) => -(add (shl x, N), x) (mul x, 2^N - 1) => (sub (shl x, N), x) (mul x, -(2^N - 1)) => (sub x, (shl x, N)) ``` And the cycles or latency is subtarget-dependent so that we need consider the subtarget to determine to do or not do such transformation. Also data type is considered for different cycles or latency to do multiply. Differential Revision: https://reviews.llvm.org/D58950 llvm-svn: 357233

* [WebAssembly] Merge used feature sets, update atomics linkage policyThomas Lively2019-03-297-62/+156
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: It does not currently make sense to use WebAssembly features in some functions but not others, so this CL adds an IR pass that takes the union of all used feature sets and applies it to each function in the module. This allows us to prevent atomics from being lowered away if some function has opted in to using them. When atomics is not enabled anywhere, we detect whether there exists any atomic operations or thread local storage that would be stripped and disallow linking with objects that contain atomics if and only if atomics or tls are stripped. When atomics is enabled, mark it as used but do not require it of other objects in the link. These changes allow libraries that do not use atomics to be built once and linked into both single-threaded and multithreaded binaries.

* [BPF] add proper multi-dimensional array supportYonghong Song2019-03-282-35/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For multi-dimensional array like below int a[2][3]; the previous implementation generates BTF_KIND_ARRAY type like below: . element_type: int . index_type: unsigned int . number of elements: 6 This is not the best way to represent arrays, esp., when converting BTF back to headers and users will see int a[6]; instead. This patch generates proper support for multi-dimensional arrays. For "int a[2][3]", the two BTF_KIND_ARRAY types will be generated: Type #n: . element_type: int . index_type: unsigned int . number of elements: 3 Type #(n+1): . element_type: #n . index_type: unsigned int . number of elements: 2 The linux kernel already supports such a multi-dimensional array representation properly.

* [MC] Fix floating-point literal lexing.Eli Friedman2019-03-282-11/+17
| | | | | | | | | | | | | | | | | | | | | This patch has three related fixes to improve float literal lexing: 1. Make AsmLexer::LexDigit handle floats without a decimal point more consistently. 2. Make AsmLexer::LexFloatLiteral print an error for floats which are apparently missing an "e". 3. Make APFloat::convertFromString use binutils-compatible exponent parsing. Together, this fixes some cases where a float would be incorrectly rejected, fixes some cases where the compiler would crash, and improves diagnostics in some cases. Patch by Brandon Jones.
