* Allow the JIT ExecutionEngine to report details about the generated machine ↵Argyrios Kyrtzidis2009-05-181-0/+4
| | | | | | | | | | | code. Introduce a new class (MachineCodeInfo) that the JIT can fill in with details. Right now, just the address and the size of the machine code are reported. Patch by Evan Phoenix! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72040 91177308-0d34-0410-b5e6-96231b3b80d8
* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-291-7/+8
| | | | | | | | which better identifies what the optimization is doing. And is more flexible for future uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@70440 91177308-0d34-0410-b5e6-96231b3b80d8

* Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman2009-02-182-0/+19
| | | | | | | | | | | | | | | | | | | | | that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@64906 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a couple issues with the JIT and multiple modules:Nate Begeman2008-05-211-2/+7
| | | | | | | | | | | | | | 1. The "JITState" object creates a PassManager with the ModuleProvider that the jit is created with. If the ModuleProvider is removed and deleted, the PassManager is invalid. 2. The Global maps in the JIT were not invalidated with a ModuleProvider was removed. This could lead to a case where the Module would be freed, and a new Module with Globals at the same addresses could return invalid results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51384 91177308-0d34-0410-b5e6-96231b3b80d8
