* [WebAssembly] Use TargetIndex operands in DbgValue to track WebAssembly ↵Yury Delendik2019-12-201-0/+4
| | | | | | | | | | | | | | | | | | operands locations Extends DWARF expression language to express locals/globals locations. (via target-index operands atm) (possible variants are: non-virtual registers or address spaces) The WebAssemblyExplicitLocals can replace virtual registers to targertindex operand type at the time when WebAssembly backend introduces {get,set,tee}_local instead of corresponding virtual registers.

* Prune two MachineInstr.h includes, fix up depsReid Kleckner2019-10-191-1/+1
| | | | | | | | | | MachineInstr.h included AliasAnalysis.h, which includes a world of IR constructs mostly unneeded in CodeGen. Prune it. Same for DebugInfoMetadata.h. Noticed with -ftime-trace. llvm-svn: 375311
* [WebAssembly] Use named operands to identify loads and storesThomas Lively2019-03-091-0/+9
| | | | | | | | | | | | | | | | | | | Summary: Uses the named operands tablegen feature to look up the indices of offset, address, and p2align operands for all load and store instructions. This replaces brittle, incorrect logic for identifying loads and store when eliminating frame indices, which previously crashed on bulk-memory ops. It also cleans up the SetP2Alignment pass.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* Remove \brief commands from doxygen comments.Adrian Prantl2018-05-011-1/+1
| | | | | | | | | | | | | | | | We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

* CodeGen: Use MachineInstr& in TargetInstrInfo, NFCDuncan P. N. Exon Smith2016-06-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is mostly a mechanical change to make TargetInstrInfo API take MachineInstr& (instead of MachineInstr* or MachineBasicBlock::iterator) when the argument is expected to be a valid MachineInstr. This is a general API improvement. Although it would be possible to do this one function at a time, that would demand a quadratic amount of churn since many of these functions call each other. Instead I've done everything as a block and just updated what was necessary. This is mostly mechanical fixes: adding and removing `*` and `&` operators. The only non-mechanical change is to split ARMBaseInstrInfo::getOperandLatencyImpl out from ARMBaseInstrInfo::getOperandLatency. Previously, the latter took a `MachineInstr*` which it updated to the instruction bundle leader; now, the latter calls the former either with the same `MachineInstr&` or the bundle leader. As a side effect, this removes a bunch of MachineInstr* to MachineBasicBlock::iterator implicit conversions, a necessary step toward fixing PR26753. Note: I updated WebAssembly, Lanai, and AVR (despite being off-by-default) since it turned out to be easy. I couldn't run tests for AVR since llc doesn't link with it turned on. llvm-svn: 274189
* Pass DebugLoc and SDLoc by const ref.Benjamin Kramer2016-06-121-2/+2
| | | | | | | | This used to be free, copying and moving DebugLocs became expensive after the metadata rewrite. Passing by reference eliminates a ton of track/untrack operations. No functionality change intended. llvm-svn: 272512
* [WebAssembly] Enhanced register stackificationDan Gohman2016-01-281-0/+3
| | | | | | | | | | | This patch revamps the RegStackifier pass with a new tree traversal mechanism, enabling three major new features: - Stackification of values with multiple uses, using the result value of set_local - More aggressive stackification of instructions with side effects - Reordering operands in commutative instructions to enable more stackification. llvm-svn: 259009
* [WebAssembly] Rematerialize constants rather than hold them live in registers.Dan Gohman2016-01-191-0/+3
| | | | | | | | | Teach the register stackifier to rematerialize constants that have multiple uses instead of leaving them in registers. In the WebAssembly encoding, it's the same code size to materialize most constants as it is to read a value from a register. llvm-svn: 258142

* [WebAssembly] Check in an initial CFG Stackifier passDan Gohman2015-09-161-0/+12
| | | | | | | | | | | | This pass implements a simple algorithm for conversion from CFG to wasm's structured control flow. It doesn't yet handle multiple-entry loops; that will be added in a future patch. It also adds initial support for switch statements.

* WebAssembly: basic bitcode → assembly CodeGen testJF Bastien2015-07-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Add a basic CodeGen bitcode test which (for now) only prints out the function name and nothing else. The current code merely implements the basic needed for the test run to not crash / assert. Getting to that point required: - Basic InstPrinter. - Basic AsmPrinter. - DiagnosticInfoUnsupported (not strictly required, but nice to have, duplicated from AMDGPU/BPF's ISelLowering). - Some SP and register setup in WebAssemblyTargetLowering. - Basic LowerFormalArguments. - GenInstrInfo. - Placeholder LowerFormalArguments. - Placeholder CanLowerReturn and LowerReturn. - Basic DAGToDAGISel::Select, which requiresGenDAGISel.inc as well as GET_INSTRINFO_ENUM with GenInstrInfo.inc. - Remove WebAssemblyFrameLowering::determineCalleeSaves and rely on default. - Implement WebAssemblyFrameLowering::hasFP, same as AArch64's implementation. Follow-up patches will implement a real AsmPrinter, which will require adding MI opcodes specific to WebAssembly.
