Hi,
simple peeling heuristic thinks it makes no sense to peel loops with known
iteration count (because they will be runtime unrolled instead). This is not
true because the known iteration count is only upper bound. Fixed this.
To make testcase possible I had to reduce overactive heuristic on numb
Hi,
this patch fixes heuristic on decide_unroll_constant_iterations to take into
account the profile: even when the loop is known to have constant loop
iteration bound, it doesn't need to really iterate many times. So use profile
and loop_max to double check that this is the case.

Hi,
the TLC path I sent last week became outdated for few reaons. I decided to
split it up for easier reviewing.
This is simple correcntess issue I am comitting as obvoius - my last update to
loop-iv missed the fact
that loop-iv bounds may depend on further conditions. In that case we can not

Hi,
this patch applies some TLC on RTL loop unroller. The following issues are
fixed:
1) while updating loop-iv.c I did not notice that the upper bound computed
is in fact conditional on infinite and assumptions flags.
The patch disables adding it if those are non-zero. I checked it do
