...moving one of the operands of a two address instruction. Whether you choose to use the two-address pass or not (your choice), you should make sure that the first two operands of the instructions are assigned to the same register, and then you delete one. For example, before RA you might have: vreg1024 = ADDxxx vreg1025, 123 after, you should have: ADDxxx EAX, 123 Where the "EAX" operand is marked as a def&use operand. -Chris -- http://nondot.org/sabre/ http://llvm.org/

Dear guys, I am in need of more of your help. I'm implementing a register allocator, and I am having problems to make it produce correct code. Consider this program here: int main(int argc, char ** argv) { int i, j, sum; i = argv[0][0]; j = argv[0][1]; sum = (i + j) * j; printf("Sum = %d\n", sum); } that maps to this llvm bytecode: entry (0xa785590, LLVM
