Hi, this patch adds simple code to dump and compare frequencies of basic blocks read from the profile feedback and frequencies guessed statically. It dumps basic blocks in the order of decreasing frequencies from feedback along with guessed frequencies and histograms.
It makes it to possible spot basic blocks in hot regions that are considered cold by guessed profile or vice versa. I am trying to figure out how realistic our profile estimate is compared to read one on exchange2 (looking again into PR98782. There IRA now places spills into hot regions of code while with older (and worse) profile it did not. Catch is that the function is very large and has 9 nested loops, so it is hard to figure out how to improve the profile estimate and/or IRA. So here I get: Basic block 136 guessed freq: 17.548 cummulative: 0.60% feedback freq: 51.848 cummulative: 1.94% cnt: 101811269914 Basic block 137 guessed freq: 15.618 cummulative: 1.14% feedback freq:
