zero_reg
Hi all,
what is exactly "zero_reg"?
from ARMInstFromats.td:
*def pred : PredicateOperand<OtherVT, (ops i32imm, i32imm), (ops (i32 14),
(i32 zero_reg))> {...}*
I thought zero_reg can be replace by a random name like (alu_stat_reg for
alu state register) but when I compiled it, I figure out that zero_reg is a
predefined variable.
Can someone plea...
