Subject: Re: [PATCH v1 1/2] Genmatch: Support new flow for phi on condition
On Wed, Se
pb_0_1, 0)->src == EDGE_PRED (_pb_1_1, 0)->src)
...
I also think we may want to split out this CFG matching code out into
a helper function
in gimple-match-head.cc instead of repeating it fully for each pattern?
Thanks,
Richard.
