2004-07-06Do not crash when joining two intervals of registers of differentAlkis Evlogimenos
classes: just ignore that move. Thanks to Vladimir Prus who found the bug! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14644 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-06Fix a bug in the unreachable block elim pass. Dropping all references on aChris Lattner
basic block clear()'s all of the operands lists, including phis. This caused removePredecessor to get confused later. Because of this, we just nuke (without prejudice) PHI nodes in unreachable blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14635 91177308-0d34-0410-b5e6-96231b3b80d8

2004-07-02Revert patches 1.79 and 1.80 which had to do with dead MBB's. Now that theyChris Lattner
don't exist, we don't have to pretend to handle them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14567 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-02Add a trivially simple pass to delete unreachable blocks from the CFG. ThisChris Lattner
pass is required to paper over problems in the code generator (primarily live variables and its clients) which doesn't really have any well defined semantics for unreachable code. The proper solution to this problem is to have instruction selectors not select blocks that are unreachable. Until we have a instruction selection framework available for use, however, we can't expect all instruction selector writers to do this. Until then, this pass should be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14563 91177308-0d34-0410-b5e6-96231b3b80d8
2004-07-01Make sure that we destroy the MBB's, with all of their instructions, beforeChris Lattner

Also convert df_iterator -> df_ext_iterator for subsequent stuff I'm doing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14517 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-27Do not find these ugly sparc-specific objects by using the annotation API onChris Lattner
instructions. Instead, keep a map of instructions -> MCFI objects in the already sparc-specific class MachineFunctionInfo. This will slow down the sparc backend a bit, but it does not penalize the rest of LLVM! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14438 91177308-0d34-0410-b5e6-96231b3b80d8
2004-06-25Made a fix so that you can print out MachineInstrs that belong to a ↵Tanya Lattner
MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14389 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-16Fix a recent regression in Applications/sgefa that Alkis pointed out to me.Chris Lattner
The vector may actually be empty if the register that we are marking as recently used is not actually allocatable. This happens for physical registers that are not allocatable, like the ST(x) registers on X86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14195 91177308-0d34-0410-b5e6-96231b3b80d8
