2016-09-11[ORC] Update examples for header changes in r281171.Lang Hames1-2/+2
llvm-svn: 281178
2016-08-26Fix singlton -> singleton typo.Eric Christopher5-5/+5
llvm-svn: 279801
2016-08-17Replace a few more "fall through" comments with LLVM_FALLTHROUGHJustin Bogner1-2/+2
Follow up to r278902. I had missed "fall through", with a space. llvm-svn: 278970
2016-08-11Use the range variant of find instead of unpacking begin/endDavid Majnemer1-2/+1
If the result of the find is only used to compare against end(), just use is_contained instead. No functionality change is intended. llvm-svn: 278433
2016-08-01[ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.Lang Hames6-35/+33
This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class that is capable of lazy materialization (i.e. the symbol definition needn't be emitted until the address is requested). This can be used to support common and weak symbols in the JIT (though this is not implemented in this patch). For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver. For space efficiency a new class, JITEvaluatedSymbol, is introduced that behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an address and symbol flags. Instances of JITEvaluatedSymbol can be used in symbol-tables to avoid paying the space cost of the materializer. llvm-svn: 277386

llvm-svn: 275518
2016-07-02New Kaleidoscope chapter: Creating object filesWilfred Hughes4-328/+1552
This new chapter describes compiling LLVM IR to object files. The new chaper is chapter 8, so later chapters have been renumbered. Since this brings us to 10 chapters total, I've also needed to rename the other chapters to use two digit numbering. Differential Revision: http://reviews.llvm.org/D18070 llvm-svn: 274441
2016-06-11[MCJIT] Update MCJIT and get the fibonacci example working again.Lang Hames2-0/+3
MCJIT will now set the DataLayout on a module when it is added to the JIT, rather than waiting until it is codegen'd, and the runFunction method will finalize the module containing the function to be run before running it. The fibonacci example has been updated to include and link against MCJIT. llvm-svn: 272455
2016-05-31[Orc] Add conversion to/from RuntimeDyld::SymbolInfo for JITSymbol.Lang Hames6-8/+8
This tidies up some code that was manually constructing RuntimeDyld::SymbolInfo instances from JITSymbols. It will save more mess in the future when JITSymbol::getAddress is extended to return an Expected<TargetAddress> rather than just a TargetAddress, since we'll be able to embed the error checking in the conversion. llvm-svn: 271350
2016-05-30[Kaleidoscope][BuildingAJIT] Don't build Chapter 5 on Windows for now.Lang Hames1-1/+3
The TCP setup code is currently *nix based and does not build on Windows. llvm-svn: 271194
2016-05-30[Kaleidoscope][BuildingAJIT] Add code for Chapter 5 - remote JITing.Lang Hames7-0/+1789
This chapter demonstrates lazily JITing from ASTs with the expressions being executed on a remote machine via a TCP connection. It needs some polish, but is substantially complete. Currently x86-64 SysV ABI (Darwin and Linux) only, but other architectures can be supported by changing the server code to use alternative ABI support classes from llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h. llvm-svn: 271193

2016-05-26[Kaleidoscope][BuildingAJIT] Fix a bug in the symbol resolver in Chapter2.Lang Hames1-1/+1
Symbol resolution should be done on the top layer of the stack unless there's a good reason to do otherwise. In this case it would have worked because OptimizeLayer::addModuleSet eagerly passes all modules down to the CompileLayer, meaning that searches in CompileLayer will find the definitions. In later chapters where the top layer's addModuleSet isn't a pass-through, this would break. llvm-svn: 270899

2015-09-09[PM/AA] Rebuild LLVM's alias analysis infrastructure in a way compatibleChandler Carruth4-12/+0
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.
