[LLVMdev] Inserting move instruction
Hi, again,
I think I got around this problem of discovering the class of a
physical register. I am using this code here:
void PhiDeconstruction_Fer::add_move
(MachineBasicBlock & mbb, unsigned src, unsigned
dst) {
MachineBasicBlock::iterator iter = mbb.getFirstTerminator();
const MRegisterInfo * reg_info =
this->machine_function->getTarget().getRegisterInfo();
// TODO: verify if does...

I was thinking that it only transformed instructions with virtual
registers because of this code in the TwoAddressInstructionPass.cpp:

[LLVMdev] Inserting move instruction
Dear llvmers,
I am trying to insert a move instruction where both source and
destination registers are physical registers. How is the code for this?
I tried this one here:
void PhiDeconstruction_Fer::add_move (
MachineFunction & mf,
MachineBasicBlock & mbb,
unsigned src,
unsigned dst
)
{
MachineBasicB...

...on of the register classes the
registers are in, but computing this on the fly would be horribly
inefficient and building big tables of these would take a bunch of space.
You'd be far better off by not throwing away the information you need
earlier.
