2012-03-11llvm::SwitchInstStepan Dyatkovskiy
Renamed methods caseBegin, caseEnd and caseDefault with case_begin, case_end, and case_default. Added some notes relative to case iterators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152532 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-08Taken into account Duncan's comments for r149481 dated by 2nd Feb 2012:Stepan Dyatkovskiy
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120130/136146.html Implemented CaseIterator and it solves almost all described issues: we don't need to mix operand/case/successor indexing anymore. Base iterator class is implemented as a template since it may be initialized either from "const SwitchInst*" or from "SwitchInst*". ConstCaseIt is just a read-only iterator. CaseIt is read-write iterator; it allows to change case successor and case value. Usage of iterator allows totally remove resolveXXXX methods. All indexing convertions done automatically inside the iterator's getters. Main way of iterator usage looks like this: SwitchInst *SI = ... // intialize it somehow for (SwitchInst::CaseIt i = SI->caseBegin(), e = SI->caseEnd(); i != e; ++i) { BasicBlock *BB = i.getCaseSuccessor(); ConstantInt *V = i.getCaseValue(); // Do something. } If you want to convert case number to TerminatorInst successor index, just use getSuccessorIndex iterator's method. If you want initialize iterator from TerminatorInst successor index, use CaseIt::fromSuccessorIndex(...) method. There are also related changes in llvm-clients: klee and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152297 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24EE/Interpreter/ExternalFunctions.cpp: Prune "C" linkage to suppress warnings ↵NAKAMURA Takumi
with -Wreturn-type (and MSC's w4190). In historical reason, Interpreter's external entries had prefix "lle_X_" as C linkage, even for well-known entries in EE/Interpreter. Now, at least on ToT, they are resolved via FuncNames[] mapper. We will not need their symbols are expected to be exported any more.

2012-02-01SwitchInst refactoring.Stepan Dyatkovskiy
The purpose of refactoring is to hide operand roles from SwitchInst user (programmer). If you want to play with operands directly, probably you will need lower level methods than SwitchInst ones (TerminatorInst or may be User). After this patch we can reorganize SwitchInst operands and successors as we want. What was done: 1. Changed semantics of index inside the getCaseValue method: getCaseValue(0) means "get first case", not a condition. Use getCondition() if you want to resolve the condition. I propose don't mix SwitchInst case indexing with low level indexing (TI successors indexing, User's operands indexing), since it may be dangerous. 2. By the same reason findCaseValue(ConstantInt*) returns actual number of case value. 0 means first case, not default. If there is no case with given value, ErrorIndex will returned. 3. Added getCaseSuccessor method. I propose to avoid usage of TerminatorInst::getSuccessor if you want to resolve case successor BB. Use getCaseSuccessor instead, since internal SwitchInst organization of operands/successors is hidden and may be changed in any moment. 4. Added resolveSuccessorIndex and resolveCaseIndex. The main purpose of these methods is to see how case successors are really mapped in TerminatorInst. 4.1 "resolveSuccessorIndex" was created if you need to level down from SwitchInst to TerminatorInst. It returns TerminatorInst's successor index for given case successor. 4.2 "resolveCaseIndex" converts low level successors index to case index that curresponds to the given successor. Note: There are also related compatability fix patches for dragonegg, klee, llvm-gcc-4.0, llvm-gcc-4.2, safecode, clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149481 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Rewrite the CMake build to use explicit dependencies between libraries,Chandler Carruth
specified in the same file that the library itself is created. This is more idiomatic for CMake builds, and also allows us to correctly specify dependencies that are missed due to bugs in the GenLibDeps perl script, or change from compiler to compiler. On Linux, this returns CMake to a place where it can relably rebuild several targets of LLVM. I have tried not to change the dependencies from the ones in the current auto-generated file. The only places I've really diverged are in places where I was seeing link failures, and added a dependency. The goal of this patch is not to start changing the dependencies, merely to move them into the correct location, and an explicit form that we can control and change when necessary. This also removes a serialization point in the build because we don't have to scan all the libraries before we begin building various tools. We no longer have a step of the build that regenerates a file inside the source tree. A few other associated cleanups fall out of this. This isn't really finished yet though. After talking to dgregor he urged switching to a single CMake macro to construct libraries with both sources and dependencies in the arguments. Migrating from the two macros to that style will be a follow-up patch. Also, llvm-config is still generated with GenLibDeps.pl, which means it still has slightly buggy dependencies. The internal CMake 'llvm-config-like' macro uses the correct explicitly specified dependencies however. A future patch will switch llvm-config generation (when using CMake) to be based on these deps as well. This may well break Windows. I'm getting a machine set up now to dig into any failures there. If anyone can chime in with problems they see or ideas of how to solve them for Windows, much appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136433 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-09Land the long talked about "type system rewrite" patch. ThisChris Lattner
patch brings numerous advantages to LLVM. One way to look at it is through diffstat: 109 files changed, 3005 insertions(+), 5906 deletions(-) Removing almost 3K lines of code is a good thing. Other advantages include: 1. Value::getType() is a simple load that can be CSE'd, not a mutating union-find operation. 2. Types a uniqued and never move once created, defining away PATypeHolder. 3. Structs can be "named" now, and their name is part of the identity that uniques them. This means that the compiler doesn't merge them structurally which makes the IR much less confusing. 4. Now that there is no way to get a cycle in a type graph without a named struct type, "upreferences" go away. 5. Type refinement is completely gone, which should make LTO much MUCH faster in some common cases with C++ code. 6. Types are now generally immutable, so we can use "Type *" instead "const Type *" everywhere. Downsides of this patch are that it removes some functions from the C API, so people using those will have to upgrade to (not yet added) new API. "LLVM 3.0" is the right time to do this. There are still some cleanups pending after this, this patch is large enough as-is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134829 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.
