--- Comment #10 from davidxl at google dot com ---
My patch does this.
1) it first does aggressive simplification iteratively (more rules can be added
later).
2) it then does normalization by building up larger predicate trees by
following ud

It seems like the whole problem is that the loop early exit goes through
bb_6 which is the same path the back-edge goes through.
There is also one

Confirmed with the C++ FE, works with the C FE. Does not warn on trunk (for

When an incoming edge to a phi is a critical edge, the 'use BB' for the phi arg
should be in the split BB of the edge. Pushing the use into either the Source
BB or the dest BB will result

Assuming the size of histogram for the same file does not vary that
much, is it better to round the size to the next power of 2 -- 60
entries will need print out 64 etc
