2016-05-30[Kaleidoscope][BuildingAJIT] Don't build Chapter 5 on Windows for now.Lang Hames
The TCP setup code is currently *nix based and does not build on Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@271194 91177308-0d34-0410-b5e6-96231b3b80d8
2016-05-30[Kaleidoscope][BuildingAJIT] Add code for Chapter 5 - remote JITing.Lang Hames
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@271193 91177308-0d34-0410-b5e6-96231b3b80d8

2016-05-26[Kaleidoscope][BuildingAJIT] Fix a bug in the symbol resolver in Chapter2.Lang Hames
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@270899 91177308-0d34-0410-b5e6-96231b3b80d8

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

2015-08-26Big Kaleidoscope tutorial update.Lang Hames
This commit switches the underlying JIT for the Kaleidoscope tutorials from MCJIT to a custom ORC-based JIT, KaleidoscopeJIT. This fixes a lot of the bugs in Kaleidoscope that were introduced when we deleted the legacy JIT. The documentation for Chapter 4, which introduces the JIT APIs, is updated to reflect the change. Also included are a number of C++11 modernizations and general cleanup. Where appropriate, the docs have been updated to reflect these changes too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@246002 91177308-0d34-0410-b5e6-96231b3b80d8

2015-07-24DI/Verifier: Fix argument bitrot in DILocalVariableDuncan P. N. Exon Smith
Add a verifier check that `DILocalVariable`s of tag `DW_TAG_arg_variable` always have a non-zero 'arg:' field, and those of tag `DW_TAG_auto_variable` always have a zero 'arg:' field. These are the only configurations that are properly understood by the backend. (Also, fix the bad examples in LangRef and test/Assembler, and fix the bug in Kaleidoscope Ch8.) A large number of testcases seem to have bitrotted their way forward from some ancient version of the debug info hierarchy that didn't have `arg:` parameters. If you have out-of-tree testcases that start failing in the verifier and you don't care enough to get the `arg:` right, you may have some luck just calling: sed -e 's/, arg: 0/, arg: 1/' or some such, but I hand-updated the ones in tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@243183 91177308-0d34-0410-b5e6-96231b3b80d8
