llvm functionanalysismanager

Invalidate analyses cached for an IR unit. This provides a good default optimization pipeline for link-time optimization and code generation. This extension point allows adding CallGraphSCC passes at the end of the main CallGraphSCC passes and before any function simplification passes run by CGPassManager. Get the cached result of an analysis pass for this module. Build the default AAManager with the default alias analysis pipeline registered. This is a long pipeline and uses most of the per-function optimization passes in LLVM to canonicalize and simplify the IR.

Definition at line 89 of file PassManagerImpl.h. Construct the module pipeline that performs inlining as well as the inlining-driven cleanups. Parse a textual pass pipeline description into a ModulePassManager. It does, however, perform inlining and other heuristic based simplifications that are not strictly reversible. Definition at line 1783 of file PassBuilder.cpp. C++ source code API documentation for LLVM. It is useful when the IR is being removed and we want to clear out all the memory pinned for it. Clear all analysis results cached by this AnalysisManager. llvm::FunctionAnalysisManager & functionAnalysisManager() Returns a reference to the function analysis manager. {{@ Parse a textual pass pipeline description into a specific PassManager. Using these callbacks, callers can parse both a single pass name, as well as entire sub-pipelines, and populate the PassManager instance accordingly. Build an ThinLTO default optimization pipeline to a pass manager. This pipeline focuses on canonicalizing and simplifying the entire module of IR. This extension point allows adding optimizations before the function optimization pipeline. Digging into this: Our pass derives from llvm::PassInfoMixin<DeadLoopRemovalPass>, taking itself as the template argument (the CRTP paradigm). References llvm::AnalysisManager< IRUnitT, ExtraArgTs >::getCachedResult(), M, and MAM. These passes will be inserted after each instance of the instruction combiner pass.

Instead, this layer is only responsible for SCC-local invalidation events.

It works to minimize the IR which needs to be analyzed without making irreversible decisions which could be made better during the LTO run. Definition at line 42 of file InstructionSimplify.h. 1.8.6 The analysis type to register is the type returned by calling the PassBuilder argument. Callees register their analyses with the given AnalysisManager objects. (Note: Although the return value of this function indicates whether or not an analysis was previously registered, there intentionally isn't a way to query this directly. Copyright 2003-2014 University of Illinois at Urbana-Champaign. This doesn't invalidate, but instead simply deletes, the relevant results. This is an interface that can be used to cross register each AnalysisManager with all the others analysis managers. The format of the textual pass pipeline description looks something like: module(function(instcombine,sroa),dce,cgscc(inliner,function()),). Definition at line 735 of file IR/PassManager.h. your pass inherits PassInfoMixin), then your own run () receives the FunctionAnalysisManager as an argument.

More #include "llvm/CodeGen/MachinePassManager.h". This should only be used for non-LTO and LTO pre-link pipelines. This allows passing in a lambda to construct the analysis. According to the C standard, unsigned overflow is defined behavior, so i*N+j calculation will be done with 32-bit types, zero-extented to 64 bit and will be used as offset in GEP instruction. Basically, just pass the flags -mllvm --rotation-max-header-size=0 to ld.lld when compiling with -Oz. This extension point allows adding optimizations at the start of the full LTO pipeline. ExtraArgTs>. The PassRegistry.def file specifies how to construct all of the built-in passes, and those may reference these members during construction. All passes are comma separated. So, assuming function passes 'fpassN', CGSCC passes 'cgpassN', and loop passes 'lpassN', all of these are valid: fpass1,fpass2,fpass3 cgpass1,cgpass2,cgpass3 lpass1,lpass2,lpass3.

Feb 10 2022, 7:46 AM. Cross register the analysis managers through their proxies. This is the place to add passes that can remove loops, such as target- specific loop idiom recognition.

It is suitable to run repeatedly over the IR and is not expected to destroy important information about the semantics of the IR. Invalidate cached analyses for an IR unit. This is an interface that can be used to populate a ModuleAnalysisManager with all registered module analyses. Note that Level cannot be O0 here. I am currently writing a frontend language compiling to LLVM IR using the LLVM c++ API (LLVM version 13), however I see some erratic behavior with segmentation faults when running the new ModulePassManager. chromium / native_client / nacl-llvm-project-v10 / refs/heads/saigo-2022-09-01 / .
