| | | | | | | | | | | | | | | | 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.

* Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin2009-11-161-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make the need-stub variables accurate and consistent. In the case ofJeffrey Yasskin2009-11-071-15/+13
| | | | | | | | | | | | | | MachineRelocations, "stub" always refers to a far-call stub or a load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs are used for lazy compilation and dlsym address replacement.) The variable was also inconsistent between the positive and negative sense, and the positive sense ("NeedStub") was more demanding than is accurate (since a nearby-enough function can be called directly even if the platform often requires a stub). Since the negative sense causes double-negatives, I switched to "MayNeedFarStub" globally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86363 91177308-0d34-0410-b5e6-96231b3b80d8

This patch also removes the Function* parameter to JITEventListener::NotifyFreeingMachineCode() since it can cause that to be called when the Function is partially destroyed.

* Move the Function*->allocated blocks map from the JITMemoryManager to theJeffrey Yasskin2009-10-202-34/+30
| | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84651 91177308-0d34-0410-b5e6-96231b3b80d8
* Clean up the JITResolver stub/callsite<->function maps.Jeffrey Yasskin2009-10-191-44/+100
| | | | | | | | | | | | | | | | | | The JITResolver maps Functions to their canonical stubs and all callsites for lazily-compiled functions to their target Functions. To make Function destruction work, I'm going to need to remove all callsites on destruction, so this patch also adds the reverse mapping for that. There was an incorrect assumption in here that the only stub for a function would be the one caused by needing to lazily compile it, while x86-64 far calls and dlsym-stubs could also cause such stubs, but I didn't look for a test case that the assumption broke. This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of std::maps. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84522 91177308-0d34-0410-b5e6-96231b3b80d8
