2009-07-08Add an option to allocate JITed global data separately from code. ByJeffrey Yasskin
default, this option is not enabled to support clients who rely on this behavior. Fixes http://llvm.org/PR4483 A patch to allocate additional memory for globals after we run out is forthcoming.

allocating memory in the JIT. This is insanely inefficient, but hey, most people implement their own memory managers anyway. Patch by Eric Yew! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66472 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-18Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman
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

2008-08-07Rewrite JIT handling of GlobalVariables so theyDale Johannesen
are allocated in the same buffer as the code, jump tables, etc. The default JIT memory manager does not handle buffer overflow well. I didn't introduce this and I'm not attempting to fix it here, but it is more likely to be hit now since we're putting more stuff in the buffer. This affects one test that I know of so far, MultiSource/Benchmarks/NPB-serial/is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54442 91177308-0d34-0410-b5e6-96231b3b80d8
