It is missing validity checks, so it is known broken. However, it is powerful enough
to compile this contrived code:
void test1(int C, double A, double B, double *P) {
double Tmp = A*A+B*B;
*P = C ? Tmp : A;
}
into:
_test1:
movsd 8(%esp), %xmm0
cmpl $0, 4(%esp)
je LBB1_2 # entry
LBB1_1: # entry
movsd 16(%esp), %xmm1
mulsd %xmm1, %xmm1
mulsd %xmm0, %xmm0
addsd %xmm1, %xmm0
LBB1_2: # entry
movl 24(%esp), %eax
movsd %xmm0, (%eax)
ret
instead of:
_test1:
movsd 16(%esp), %xmm0
mulsd %xmm0, %xmm0
movsd 8(%esp), %xmm1
movapd %xmm1, %xmm2
mulsd %xmm2, %xmm2

a header file from libcodegen. This violates a layering order: codegen

stuff that depends on libcodegen. It is defined in libcodegen, where
the base is not.

that "machine" classes are used to represent the current state of

from MachineFunction.

getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

- Move SubReg out of the AuxInfo union, to make way for future changes.
- Remove the getImmedValue/setImmedValue methods.
- in some MachineOperand::Create* methods, stop initializing fields that are dead.
MachineInstr:
- Delete one copy of the MachineInstr printing code, now there is only one dump
format and one copy of the code.
- Make MachineOperand use the parent field to get info about preg register names if
no target info is otherwise available.
- Move def/use/kill/dead flag printing to the machineoperand printer, so they are
always printed for an operand.
