* Partially revert r91626. Materializing extra functions to determine whetherJeffrey Yasskin2009-12-222-7/+97
| | | | | | | | | | | they're available_externally broke VMKit, which was relying on the fact that functions would only be materialized when they were first called. We'll have to wait for http://llvm.org/PR5737 to really fix this. I also added a test for one of the F->isDeclaration() calls which wasn't covered by anything else in the test suite. llvm-svn: 91943

* * Move stub allocation inside the JITEmitter, instead of exposing aJeffrey Yasskin2009-11-231-3/+34
| | | | | | | | | | | | | | 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. llvm-svn: 89715

* Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin2009-11-161-6/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The large code model is documented at http://www.x86-64.org/documentation/abi.pdf and says that calls should assume their target doesn't live within the 32-bit pc-relative offset that fits in the call instruction. To do this, we turn off the global-address->target-global-address conversion in X86TargetLowering::LowerCall(). The first attempt at this broke the lazy JIT because it can separate the movabs(imm->reg) from the actual call instruction. The lazy JIT receives the address of the movabs as a relocation and needs to record the return address from the call; and then when that call happens, it needs to patch the movabs with the newly-compiled target. We could thread the call instruction into the relocation and record the movabs<->call mapping explicitly, but that seems to require at least as much new complication in the code generator as this change. To fix this, we make lazy functions _always_ go through a call stub. You'd think we'd only have to force lazy calls through a stub on difficult platforms, but that turns out to break indirect calls through a function pointer. The right fix for that is to distinguish between calls and address-of operations on uncompiled functions, but that's complex enough to leave for someone else to do. Another attempt at this defined a new CALL64i pseudo-instruction, which expanded to a 2-instruction sequence in the assembly output and was special-cased in the X86CodeEmitter's emitInstruction() function. That broke indirect calls in the same way as above. This patch also removes a hack forcing Darwin to the small code model. Without far-call-stubs, the small code model requires things of the JITMemoryManager that the DefaultJITMemoryManager can't provide. Thanks to echristo for lots of testing! llvm-svn: 88984

| | | | | | | | | | | | | being destroyed. This allows users to run global optimizations like globaldce even after some functions have been jitted. This patch also removes the Function* parameter to JITEventListener::NotifyFreeingMachineCode() since it can cause that to be called when the Function is partially destroyed. This change will be even more helpful later when I think we'll want to allow machine code to actually outlive its Function. llvm-svn: 85182
* Fix http://llvm.org/PR4822: allow module deletion after a function has beenJeffrey Yasskin2009-10-232-3/+30
| | | | | | | | | | | | | | compiled. When functions are compiled, they accumulate references in the JITResolver's stub maps. This patch removes those references when the functions are destroyed. It's illegal to destroy a Function when any thread may still try to call its machine code. This patch also updates r83987 to use ValueMap instead of explicit CallbackVHs and fixes a couple "do stuff inside assert()" bugs from r84522. llvm-svn: 84975
* Move the Function*->allocated blocks map from the JITMemoryManager to theJeffrey Yasskin2009-10-201-38/+39
| | | | | | | | | | | | | | | JITEmitter. I'm gradually making Functions auto-remove themselves from the JIT when they're destroyed. In this case, the Function needs to be removed from the JITEmitter, but the map recording which Functions need to be removed lived behind the JITMemoryManager interface, which made things difficult. This patch replaces the deallocateMemForFunction(Function*) method with a pair of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *) corresponding to the two startFoo/endFoo pairs. llvm-svn: 84651

Also, switch function stubs and global data over to using the BumpPtrAllocator. This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB of memory, and instead allocates in 512K slabs.
