[LLVMdev] reg_iterator Caveats
...l* the
uses/defs of that register in the current function. If the value is
SSA form, it is reasonable to say "give me the first def" and expect
it to be the only def. For multiply defined values like physregs,
this is not true, because the reg can have multiple defs.
That said, ref_iterator and variants will always do what they are
documented to, they just don't magically provide ssa-like properties
for physregs.
