and add a FIXME about how we are eventually going to zap this lookup table once mc world domination is complete. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98031 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04Fix PR6360. It's easy for a stub's address to escape to user code, so we can'tJeffrey Yasskin
just count references to it from JIT output to decide when to destroy it. This patch waits to destroy the JIT's memory of a stub until the Function it refers to is destroyed. External function stubs and GVIndirectSyms aren't destroyed until the JIT itself is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97737 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04Fix PR5291, in which a SmallPtrSet iterator was held across an insertion intoJeffrey Yasskin

2010-03-04Make sure JITResolvers don't leave any stubs behind. When a JITResolver wasJeffrey Yasskin
destroyed, it could leave stubs in the StubToResolverMap, which would confuse the lookup for subsequent lazy compilations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97698 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-16There are two ways of checking for a given type, for example isa<PointerType>(T)Duncan Sands
and T->isPointerTy(). Convert most instances of the first form to the second form. Requested by Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96344 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15Uniformize the names of type predicates: rather than having isFloatTy andDuncan Sands
isInteger, we now have isFloatTy and isIntegerTy. Requested by Chris! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96223 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-11Make it possible to create multiple JIT instances at the same time, by removingJeffrey Yasskin
the global TheJIT and TheJITResolver variables. Lazy compilation is supported by a global map from a stub address to the JITResolver that knows how to compile it. Patch by Olivier Meurant! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95837 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95781 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-05Move --march, --mcpu, and --mattr from JIT/TargetSelect.cpp to lli.cpp.Jeffrey Yasskin
llc.cpp also defined these flags, meaning that when I linked all of LLVM's libraries into a single shared library, llc crashed on startup with duplicate flag definitions. This patch passes them through the EngineBuilder into JIT::selectTarget(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95390 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-03r94686 changed all ModuleProvider parameters to Modules, which made theJeffrey Yasskin
1-argument ExecutionEngine::create(Module*) ambiguous with the signature that used to be ExecutionEngine::create(ModuleProvider*, defaulted_params). Fixed by removing the 1-argument create(). Fixes PR6221. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95236 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-28Replace strcpy with memcpy when we have the length around anyway.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94746 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. Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94686 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-26make jit jump table emission be based on the EntryKind instead of magic ↵Chris Lattner
variables. JITInfo::getPICJumpTableEntry can probably be removed now, but I don't plan to do this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94501 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-25Rearrange handling of jump tables. Highlights:Chris Lattner
1. MachineJumpTableInfo is now created lazily for a function the first time it actually makes a jump table instead of for every function. 2. The encoding of jump table entries is now described by the MachineJumpTableInfo::JTEntryKind enum. This enum is determined by the TLI::getJumpTableEncoding() hook, instead of by lots of code scattered throughout the compiler that "knows" that jump table entries are always 32-bits in pic mode (for example). 3. The size and alignment of jump table entries is now calculated based on their kind, instead of at machinefunction creation time. Future work includes using the EntryKind in more places in the compiler, eliminating other logic that "knows" the layout of jump tables in various situations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94470 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22Make OProfile support compile again after r93630 removedJeffrey Yasskin
DebugLocTuple. Also use an AssertingVH to ensure that MDNodes aren't destroyed while the FilenameCache is using them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94245 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-22Stop building RTTI information for *most* llvm libraries. NotableChris Lattner
missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94164 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-09"In order to ease automatic bindings generation, it would be helpful if ↵Chris Lattner

2009-12-22Partially revert r91626. Materializing extra functions to determine whetherJeffrey Yasskin
they're available_externally broke VMKit, which was relying on the fact that functions would only be materialized when they were first called.

2009-12-15Change indirect-globals to use a dedicated allocIndirectGV. This lets usJeffrey Yasskin
remove start/finishGVStub and the BufferState helper class from the MachineCodeEmitter interface.

2009-11-23* Move stub allocation inside the JITEmitter, instead of exposing aJeffrey Yasskin
way for each TargetJITInfo subclass to allocate its own stubs. This means stubs aren't as exactly-sized anymore, but it lets us get rid of TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC support the eager JIT, fixing http://llvm.org/PR4816. * Rename the JITEmitter's stub creation functions to describe the kind of stub they create. So far, all of them create lazy-compilation stubs, but they sometimes get used when far-call stubs are needed. Fixing http://llvm.org/PR5201 will involve fixing this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89715 91177308-0d34-0410-b5e6-96231b3b80d8
