* Fix build error from previous commit.Andrew Kaylor2012-11-06

* Add interface for object-based JIT events.Andrew Kaylor2012-11-06
| | | | | | This patch adds the interface to expose events from MCJIT when an object is emitted or freed and implements the MCJIT functionality to send those events. The IntelJITEventListener implementation is left empty for now. It will be fleshed out in a future patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167475 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-05
| | | | | | Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8
* Change resolveRelocation parameters so the relocations can find placeholder ↵Andrew Kaylor2012-11-02
| | | | | | | | values in the original object buffer. Some ELF relocations require adding the a value to the original contents of the object buffer at the specified location. In order to properly handle multiple applications of a relocation, the RuntimeDyld code should be grabbing the original value from the object buffer and writing a new value into the loaded section buffer. This patch changes the parameters passed to resolveRelocations to accommodate this need. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167304 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove unnecessary classof()'sSean Silva2012-10-11
| | | | | | | isa<> et al. automatically infer when the cast is an upcast (including a self-cast), so these are no longer necessary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165767 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove buggy classof().Sean Silva2012-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This classof() is effectively saying that a MachineCodeEmitter "is-a" JITEmitter, but JITEmitter is in fact a descendant of MachineCodeEmitter, so this is not semantically correct. Consequently, none of the assertions that rely on these classof() actualy check anything. Remove the RTTI (which didn't actually check anything) and use static_cast<> instead. Post-Mortem Bug Analysis ======================== Cause of the bug ---------------- r55022 appears to be the source of the classof() and assertions removed by this commit. It aimed at removing some dynamic_cast<> that were solely in the assertions. A typical diff hunk from that commit looked like: - assert(dynamic_cast<JITEmitter*>(MCE) && "Unexpected MCE?"); - JITEmitter *JE = static_cast<JITEmitter*>(getCodeEmitter()); + assert(isa<JITEmitter>(MCE) && "Unexpected MCE?"); + JITEmitter *JE = cast<JITEmitter>(getCodeEmitter()); Hence, the source of the bug then seems to be an attempt to replace dynamic_cast<> with LLVM-style RTTI without properly setting up the class hierarchy for LLVM-style RTTI. The bug therefore appears to be simply a "thinko". What initially indicated the presence of the bug ------------------------------------------------ After implementing automatic upcasting for isa<>, classof() functions of the form static bool classof(const Foo *) { return true; } were removed, since they only serve the purpose of optimizing statically-OK upcasts. A subsequent recompilation triggered a build failure on the isa<> tests within the removed asserts, since the automatic upcasting (correctly) failed to substitute this classof(). Key to pinning down the root cause of the bug --------------------------------------------- After being alerted to the presence of the bug, some thought about the semantics which were being asserted by the buggy classof() revealed that it was incorrect. How the bug could have been prevented ------------------------------------- This bug could have been prevented by better documentation for how to set up LLVM-style RTTI. This should be solved by the recently added documentation HowToSetUpLLVMStyleRTTI. However, this bug suggests that the documentation should clearly explain the contract that classof() must fulfill. The HowToSetUpLLVMStyleRTTI already explains this contract, but it is a little tucked away. A future patch will expand that explanation and make it more prominent. There does not appear to be a simple way to have the compiler prevent this bug, since fundamentally it boiled down to a spurious classof() where the programmer made an erroneous statement about the conversion. This suggests that perhaps the interface to LLVM-style RTTI of classof() is not the best. There is already some evidence for this, since in a number of places Clang has classof() forward to classofKind(Kind K) which evaluates the cast in terms of just the Kind. This could probably be generalized to simply a `static const Kind MyKind;` field in leaf classes and `static const Kind firstMyKind, lastMyKind;` for non-leaf classes, and have the rest of the work be done inside Casting.h, assuming that the Kind enum is laid out in a preorder traversal of the inheritance tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165764 91177308-0d34-0410-b5e6-96231b3b80d8
