* [RuntimeDyld] Add alignment arguments to the reserveAllocationSpace method ofLang Hames2016-01-101-2/+3
| | | | | | | | | | | | | | RuntimeDyld::MemoryManager. The RuntimeDyld::MemoryManager::reserveAllocationSpace method is called when object files are loaded, and gives clients a chance to pre-allocate memory for all segments. Previously only the size of each segment (code, ro-data, rw-data) was supplied but not the alignment. This hasn't caused any problems so far, as most clients allocate via the MemoryBlock interface which returns page-aligned blocks. Adding alignment arguments enables finer grained allocation while still satisfying alignment restrictions. llvm-svn: 257294

* [PM/AA] Rebuild LLVM's alias analysis infrastructure in a way compatibleChandler Carruth2015-09-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Don't own the buffer in object::Binary.Rafael Espindola2014-08-191-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Owning the buffer is somewhat inflexible. Some Binaries have sub Binaries (like Archive) and we had to create dummy buffers just to handle that. It is also a bad fit for IRObjectFile where the Module wants to own the buffer too. Keeping this ownership would make supporting IR inside native objects particularly painful. This patch focuses in lib/Object. If something elsewhere used to own an Binary, now it also owns a MemoryBuffer. This patch introduces a few new types. * MemoryBufferRef. This is just a pair of StringRefs for the data and name. This is to MemoryBuffer as StringRef is to std::string. * OwningBinary. A combination of Binary and a MemoryBuffer. This is needed for convenience functions that take a filename and return both the buffer and the Binary using that buffer. The C api now uses OwningBinary to avoid any change in semantics. I will start a new thread to see if we want to change it and how. llvm-svn: 216002

* Add C API for thread yielding callback.Juergen Ributzka2014-05-161-0/+27
| | | | | | | | | | | | | | | | | | | | | Sometimes a LLVM compilation may take more time then a client would like to wait for. The problem is that it is not possible to safely suspend the LLVM thread from the outside. When the timing is bad it might be possible that the LLVM thread holds a global mutex and this would block any progress in any other thread. This commit adds a new yield callback function that can be registered with a context. LLVM will try to yield by calling this callback function, but there is no guaranteed frequency. LLVM will only do so if it can guarantee that suspending the thread won't block any forward progress in other LLVM contexts in the same process. Once the client receives the call back it can suspend the thread safely and resume it at another time. Related to <rdar://problem/16728690> llvm-svn: 208945

* [PM] Add pass run listeners to the pass manager.Juergen Ributzka2014-04-281-0/+28
| | | | | | | | | | | | | | | | | | This commit provides the necessary C/C++ APIs and infastructure to enable fine- grain progress report and safe suspension points after each pass in the pass manager. Clients can provide a callback function to the pass manager to call after each pass. This can be used in a variety of ways (progress report, dumping of IR between passes, safe suspension of threads, etc). The run listener list is maintained in the LLVMContext, which allows a multi- threaded client to be only informed for it's own thread. This of course assumes that the client created a LLVMContext for each thread. This fixes <rdar://problem/16728690> llvm-svn: 207430
