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

2006-03-27SelectionDAGISel can now natively handle Switch instructions, in the sameNate Begeman
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary search tree of basic blocks. The new approach has several advantages: it is faster, it generates significantly smaller code in many cases, and it paves the way for implementing dense switch tables as a jump table by handling switches directly in the instruction selector. This functionality is currently only enabled on x86, but should be safe for every target. In anticipation of making it the default, the cfg is now properly updated in the x86, ppc, and sparc select lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27156 91177308-0d34-0410-b5e6-96231b3b80d8
