Improve performance of iterating over children and accessing the member file buffer by caching the file size and moving code out to the header.

2013-01-31Give the MCStreamer class hierarchy LLVM RTTI facilities for use withChandler Carruth
isa<> and dyn_cast<>. In several places, code is already hacking around the absence of this, and there seem to be several interfaces that might be lifted and/or devirtualized using this. This change was based on a discussion with Jim Grosbach about how best to handle testing for specific MCStreamer subclasses. He said that this was the correct end state, and everything else was too hacky so I decided to just make it so. No functionality should be changed here, this is just threading the kind through all the constructors and setting up the classof overloads. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174113 91177308-0d34-0410-b5e6-96231b3b80d8

AT_producer. Which includes clang's version information so we can tell which version of the compiler was used. This is the first of two steps to allow us to do that. This is the llvm-mc change to provide a method to set the AT_producer string.

2013-01-16Introduce llvm::sys::getProcessTriple() function.Peter Collingbourne
In r143502, we renamed getHostTriple() to getDefaultTargetTriple() as part of work to allow the user to supply a different default target triple at configure time. This change also affected the JIT. However, it is inappropriate to use the default target triple in the JIT in most circumstances because this will not necessarily match the current architecture used by the process, leading to illegal instruction and other such errors at run time. Introduce the getProcessTriple() function for use in the JIT and its clients, and cause the JIT to use it. On architectures with a single bitness, the host and process triples are identical. On other architectures, the host triple represents the architecture of the host CPU, while the process triple represents the architecture used by the host CPU to interpret machine code within the current process. For example, when executing 32-bit code on a 64-bit Linux machine, the host triple may be 'x86_64-unknown-linux-gnu', while the process triple may be 'i386-unknown-linux-gnu'. This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple platforms.

2013-01-14Expose an InitToTextSection through MCStreamer.Eli Bendersky
The aim of this patch is to fix the following piece of code in the platform-independent AsmParser: void AsmParser::CheckForValidSection() { if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) { TokError("expected section directive before assembly directive"); Out.SwitchSection(Ctx.getMachOSection( "__TEXT", "__text", MCSectionMachO::S_ATTR_PURE_INSTRUCTIONS, 0, SectionKind::getText())); } } This was added for the "-n" option of llvm-mc. The proposed fix adds another virtual method to MCStreamer, called InitToTextSection. Conceptually, it's similar to the existing InitSections which initializes all common sections and switches to text. The new method is implemented by each platform streamer in a way that it sees fit. So AsmParser can now do this: void AsmParser::CheckForValidSection() { if (!ParsingInlineAsm && !getStreamer().getCurrentSection()) { TokError("expected section directive before assembly directive"); Out.InitToTextSection(); } } Which is much more reasonable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172450 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-07Switch TargetTransformInfo from an immutable analysis pass that requiresChandler Carruth
a TargetMachine to construct (and thus isn't always available), to an analysis group that supports layered implementations much like AliasAnalysis does. This is a pretty massive change, with a few parts that I was unable to easily separate (sorry), so I'll walk through it. The first step of this conversion was to make TargetTransformInfo an analysis group, and to sink the nonce implementations in ScalarTargetTransformInfo and VectorTargetTranformInfo into a NoTargetTransformInfo pass. This allows other passes to add a hard requirement on TTI, and assume they will always get at least on implementation. The TargetTransformInfo analysis group leverages the delegation chaining trick that AliasAnalysis uses, where the base class for the analysis group delegates to the previous analysis *pass*, allowing all but tho NoFoo analysis passes to only implement the parts of the interfaces they support. It also introduces a new trick where each pass in the group retains a pointer to the top-most pass that has been initialized. This allows passes to implement one API in terms of another API and benefit when some other pass above them in the stack has more precise results for the second API. The second step of this conversion is to create a pass that implements the TargetTransformInfo analysis using the target-independent abstractions in the code generator. This replaces the ScalarTargetTransformImpl and VectorTargetTransformImpl classes in lib/Target with a single pass in lib/CodeGen called BasicTargetTransformInfo. This class actually provides most of the TTI functionality, basing it upon the TargetLowering abstraction and other information in the target independent code generator. The third step of the conversion adds support to all TargetMachines to register custom analysis passes. This allows building those passes with access to TargetLowering or other target-specific classes, and it also allows each target to customize the set of analysis passes desired in the pass manager. The baseline LLVMTargetMachine implements this interface to add the BasicTTI pass to the pass manager, and all of the tools that want to support target-aware TTI passes call this routine on whatever target machine they end up with to add the appropriate passes. The fourth step of the conversion created target-specific TTI analysis passes for the X86 and ARM backends. These passes contain the custom logic that was previously in their extensions of the ScalarTargetTransformInfo and VectorTargetTransformInfo interfaces. I separated them into their own file, as now all of the interface bits are private and they just expose a function to create the pass itself. Then I extended these target machines to set up a custom set of analysis passes, first adding BasicTTI as a fallback, and then adding their customized TTI implementations. The fourth step required logic that was shared between the target independent layer and the specific targets to move to a different interface, as they no longer derive from each other. As a consequence, a helper functions were added to TargetLowering representing the common logic needed both in the target implementation and the codegen implementation of the TTI pass. While technically this is the only change that could have been committed separately, it would have been a nightmare to extract. The final step of the conversion was just to delete all the old boilerplate. This got rid of the ScalarTargetTransformInfo and VectorTargetTransformInfo classes, all of the support in all of the targets for producing instances of them, and all of the support in the tools for manually constructing a pass based around them. Now that TTI is a relatively normal analysis group, two things become straightforward. First, we can sink it into lib/Analysis which is a more natural layer for it to live. Second, clients of this interface can depend on it *always* being available which will simplify their code and behavior. These (and other) simplifications will follow in subsequent commits, this one is clearly big enough. Finally, I'm very aware that much of the comments and documentation needs to be updated. As soon as I had this working, and plausibly well commented, I wanted to get it committed and in front of the build bots. I'll be doing a few passes over documentation later if it sticks. Commits to update DragonEgg and Clang will be made presently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171681 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-05Convert the TargetTransformInfo from an immutable pass with dynamicChandler Carruth
interfaces which could be extracted from it, and must be provided on construction, to a chained analysis group. The end goal here is that TTI works much like AA -- there is a baseline "no-op" and target independent pass which is in the group, and each target can expose a target-specific pass in the group. These passes will naturally chain allowing each target-specific pass to delegate to the generic pass as needed. In particular, this will allow a much simpler interface for passes that would like to use TTI -- they can have a hard dependency on TTI and it will just be satisfied by the stub implementation when that is all that is available. This patch is a WIP however. In particular, the "stub" pass is actually the one and only pass, and everything there is implemented by delegating to the target-provided interfaces. As a consequence the tools still have to explicitly construct the pass. Switching targets to provide custom passes and sinking the stub behavior into the NoTTI pass is the next step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171621 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8
