* Move the Function*->allocated blocks map from the JITMemoryManager to theJeffrey Yasskin2009-10-201-32/+12
| | | | | | | | | | | | | | | | | 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

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. I suspect this size could go lower, especially on embedded platforms, now that more slabs can be allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76828 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | 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
