Hi Mike,
: This is a known problem (at least on the d30v with conditional execution). The
: problem is if you have:
:
: if (cond) {
: tmp = ...;
: ....
: }
:
: where tmp is a register that is not live, flow wants tmp to be live when the
: THEN block is converted to COND_EXEC format, and complains. I would say, check
: in the patch.....
Thanks for the explanation - patch checked in.
Cheers
Nick
