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

2006-05-03Suck block address tracking out of targets into the JIT Emitter. ThisChris Lattner
simplifies the MachineCodeEmitter interface just a little bit and makes BasicBlocks work like constant pools and jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28082 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-02Several related changes:Chris Lattner
1. Change several methods in the MachineCodeEmitter class to be pure virtual. 2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them from the MachineCodeEmitter interface, and reducing the amount of target- specific code. 3. Change the JITEmitter so that it allocates constantpools and jump tables *right* next to the functions that they belong to, instead of in a separate pool of memory. This makes all memory for a function be contiguous, and means the JITEmitter only tracks one block of memory now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28065 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Add a method for allocating space from the code buffer.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28064 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Do not make the JIT memory manager manage the memory for globals. InsteadChris Lattner
just have the JIT malloc them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28062 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Fix a purely hypothetical problem (for now): emitWord emits in the hostChris Lattner
byte format. This doesn't work when using the code emitter in a cross target environment. Since the code emitter is only really used by the JIT, this isn't a current problem, but if we ever start emitting .o files, it would be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28060 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-02Refactor the machine code emitter interface to pull the pointers for the currentChris Lattner
code emission location into the base class, instead of being in the derived classes. This change means that low-level methods like emitByte/emitWord now are no longer virtual (yaay for speed), and we now have a framework to support growable code segments. This implements feature request #1 of PR469. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28059 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-22JumpTable support! What this represents is working asm and jit support forNate Begeman
x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27947 91177308-0d34-0410-b5e6-96231b3b80d8

2005-07-28Like constants, globals on some platforms are GOT relative. This means they ↵Andrew Lenharth
have to be allocated near the GOT, which new doesn't do. So break out the allocate into a new function. Also move GOT index handling into JITResolver. This lets it update the mapping when a Lazy function is JITed. It doesn't managed the table, just the mapping. Note that this is still non-ideal, as any function that takes a function address should also take a GOT index, but that is a lot of changes. The relocation resolve process updates any GOT entry it sees is out of date. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22537 91177308-0d34-0410-b5e6-96231b3b80d8
