ValueIDNum is supposed to be a value type that boils down to a uint64_t,
that has some bitfields for convenience. If we use the default operator=,
we end up with each bit field being individually assigned, which is
un-necessarily slow.
Implement the assignment operator by just copying the uint64_t value of
the object. This is quicker, and matches how the comparison operators
work already. Doing so is 0.1% faster on the compile-time-tracker.
u.s = {Block, Inst, Loc.asU64()};
}
+ ValueIDNum &operator=(const ValueIDNum &Other) {
+ u.Value = Other.u.Value;
+ return *this;
+ }
+
uint64_t getBlock() const { return u.s.BlockNo; }
uint64_t getInst() const { return u.s.InstNo; }
uint64_t getLoc() const { return u.s.LocNo; }
