* Sink all InitializePasses.h includesReid Kleckner2019-11-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This file lists every pass in LLVM, and is included by Pass.h, which is very popular. Every time we add, remove, or rename a pass in LLVM, it caused lots of recompilation. I found this fact by looking at this table, which is sorted by the number of times a file was changed over the last 100,000 git commits multiplied by the number of object files that depend on it in the current checkout: recompiles touches affected_files header 342380 95 3604 llvm/include/llvm/ADT/STLExtras.h 314730 234 1345 llvm/include/llvm/InitializePasses.h 307036 118 2602 llvm/include/llvm/ADT/APInt.h 213049 59 3611 llvm/include/llvm/Support/MathExtras.h 170422 47 3626 llvm/include/llvm/Support/Compiler.h 162225 45 3605 llvm/include/llvm/ADT/Optional.h 158319 63 2513 llvm/include/llvm/ADT/Triple.h 140322 39 3598 llvm/include/llvm/ADT/StringRef.h 137647 59 2333 llvm/include/llvm/Support/Error.h 131619 73 1803 llvm/include/llvm/Support/FileSystem.h Before this change, touching InitializePasses.h would cause 1345 files to recompile.

* 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
* ScheduleDAG: Cleanup dumping code; NFCMatthias Braun2018-09-191-8/+4
| | | | | | | | | | | | - Instead of having both `SUnit::dump(ScheduleDAG*)` and `ScheduleDAG::dumpNode(ScheduleDAG*)`, just keep the latter around. - Add `ScheduleDAG::dump()` and avoid code duplication in several places. Implement it for different ScheduleDAG variants. - Add `ScheduleDAG::dumpNodeName()` in favor of the `SUnit::print()` functions. They were only ever used for debug dumping and putting the function into ScheduleDAG is consistent with the `dumpNode()` change. llvm-svn: 342520
* Rename DEBUG macro to LLVM_DEBUG.Nicola Zaghen2018-05-141-21/+23
| | | | | | | | | | | | | | | | The DEBUG() macro is very generic so it might clash with other projects. The renaming was done as follows: - git grep -l 'DEBUG' | xargs sed -i 's/\bDEBUG\s\?(/LLVM_DEBUG(/g' - git diff -U0 master | ../clang/tools/clang-format/clang-format-diff.py -i -p1 -style LLVM - Manual change to APInt - Manually chage DOCS as regex doesn't match it.

* CodeGen: Use MachineInstr& in TargetInstrInfo, NFCDuncan P. N. Exon Smith2016-06-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Initial implementation of optimization bisect support.Andrew Kaylor2016-04-211-1/+1
| | | | | | | | | | | | This patch implements a optimization bisect feature, which will allow optimizations to be selectively disabled at compile time in order to track down test failures that are caused by incorrect optimizations. The bisection is enabled using a new command line option (-opt-bisect-limit). Individual passes that may be skipped call the OptBisect object (via an LLVMContext) to see if they should be skipped based on the bisect limit. A finer level of control (disabling individual transformations) can be managed through an addition OptBisect method, but this is not yet used. The skip checking in this implementation is based on (and replaces) the skipOptnoneFunction check. Where that check was being called, a new call has been inserted in its place which checks the bisect limit and the optnone attribute. A new function call has been added for module and SCC passes that behaves in a similar way. Differential Revision: http://reviews.llvm.org/D19172 llvm-svn: 267022

* Introduce MachineFunctionProperties and the AllVRegsAllocated propertyDerek Schuff2016-03-281-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | MachineFunctionProperties represents a set of properties that a MachineFunction can have at particular points in time. Existing examples of this idea are MachineRegisterInfo::isSSA() and MachineRegisterInfo::tracksLiveness() which will eventually be switched to use this mechanism. This change introduces the AllVRegsAllocated property; i.e. the property that all virtual registers have been allocated and there are no VReg operands left. With this mechanism, passes can declare that they require a particular property to be set, or that they set or clear properties by implementing e.g. MachineFunctionPass::getRequiredProperties(). The MachineFunctionPass base class verifies that the requirements are met, and handles the setting and clearing based on the delcarations. Passes can also directly query and update the current properties of the MF if they want to have conditional behavior. This change annotates the target-independent post-regalloc passes; future changes will also annotate target-specific ones.

It was only used in a method of MachineSchedulerBase which behaved differently in MachineScheduler/PostMachineScheduler. Change this to let MachineScheduler/PostMachineScheduler just pass in a parameter to that function.

* [PM/AA] Rebuild LLVM's alias analysis infrastructure in a way compatibleChandler Carruth2015-09-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with the new pass manager, and no longer relying on analysis groups. This builds essentially a ground-up new AA infrastructure stack for LLVM. The core ideas are the same that are used throughout the new pass manager: type erased polymorphism and direct composition. The design is as follows: - FunctionAAResults is a type-erasing alias analysis results aggregation interface to walk a single query across a range of results from different alias analyses. Currently this is function-specific as we always assume that aliasing queries are *within* a function. - AAResultBase is a CRTP utility providing stub implementations of various parts of the alias analysis result concept, notably in several cases in terms of other more general parts of the interface. This can be used to implement only a narrow part of the interface rather than the entire interface. This isn't really ideal, this logic should be hoisted into FunctionAAResults as currently it will cause a significant amount of redundant work, but it faithfully models the behavior of the prior infrastructure. - All the alias analysis passes are ported to be wrapper passes for the legacy PM and new-style analysis passes for the new PM with a shared result object. In some cases (most notably CFL), this is an extremely naive approach that we should revisit when we can specialize for the new pass manager. - BasicAA has been restructured to reflect that it is much more fundamentally a function analysis because it uses dominator trees and loop info that need to be constructed for each function. All of the references to getting alias analysis results have been updated to use the new aggregation interface. All the preservation and other pass management code has been updated accordingly. The way the FunctionAAResultsWrapperPass works is to detect the available alias analyses when run, and add them to the results object. This means that we should be able to continue to respect when various passes are added to the pipeline, for example adding CFL or adding TBAA passes should just cause their results to be available and to get folded into this. The exception to this rule is BasicAA which really needs to be a function pass due to using dominator trees and loop info. As a consequence, the FunctionAAResultsWrapperPass directly depends on BasicAA and always includes it in the aggregation. This has significant implications for preserving analyses. Generally, most passes shouldn't bother preserving FunctionAAResultsWrapperPass because rebuilding the results just updates the set of known AA passes. The exception to this rule are LoopPass instances which need to preserve all the function analyses that the loop pass manager will end up needing. This means preserving both BasicAAWrapperPass and the aggregating FunctionAAResultsWrapperPass. Now, when preserving an alias analysis, you do so by directly preserving that analysis. This is only necessary for non-immutable-pass-provided alias analyses though, and there are only three of interest: BasicAA, GlobalsAA (formerly GlobalsModRef), and SCEVAA. Usually BasicAA is preserved when needed because it (like DominatorTree and LoopInfo) is marked as a CFG-only pass. I've expanded GlobalsAA into the preserved set everywhere we previously were preserving all of AliasAnalysis, and I've added SCEVAA in the intersection of that with where we preserve SCEV itself. One significant challenge to all of this is that the CGSCC passes were actually using the alias analysis implementations by taking advantage of a pretty amazing set of loop holes in the old pass manager's analysis management code which allowed analysis groups to slide through in many cases. Moving away from analysis groups makes this problem much more obvious. To fix it, I've leveraged the flexibility the design of the new PM components provides to just directly construct the relevant alias analyses for the relevant functions in the IPO passes that need them. This is a bit hacky, but should go away with the new pass manager, and is already in many ways cleaner than the prior state. Another significant challenge is that various facilities of the old alias analysis infrastructure just don't fit any more. The most significant of these is the alias analysis 'counter' pass. That pass relied on the ability to snoop on AA queries at different points in the analysis group chain. Instead, I'm planning to build printing functionality directly into the aggregation layer. I've not included that in this patch merely to keep it smaller. Note that all of this needs a nearly complete rewrite of the AA documentation. I'm planning to do that, but I'd like to make sure the new design settles, and to flesh out a bit more of what it looks like in the new pass manager first.
