ARM defaults to -fshort-enums and the following testcase FAILs there in 2
lines. The difference is that in C++, E0 has enum E type, which normally
has unsigned int underlying type, so it isn't int nor something that
promotes to int, which is why we diagnose it (in C it is promoted to int).

Hi Philipp,
Could you rebase this patch on top of master please.
Essentially we put each tuning model in its own file now.
Thanks,

Hi,
in PR112406 Tamar found another problem with COND_OP reductions.
I wrongly assumed that the reduction variable will always remain in
operand 1, just as we create the COND_OP in ifcvt. But of course,
addition being commutative, we are free to swap operand 1 and 2 and
can end up with e.g.

Sorry for barging in though I did try finding the relevant

Is it because we don't want to depend on Python being
present at build
For vec_pack_trunc patterns there can be an ambiguity for the
source mode for BFmode vs HFmode. The vectorizer checks
the insns operand mode for this, the following makes forwprop
do the same. That of course doesn't help if the target supports
both conversions.
Bootstrapped and tested on
The following moves the check whether the maximum vectorization
factor determined by data dependence analysis is in conflict with
the chosen vectorization factor to after the point where we applied
both the SLP and the unrolling adjustment to the vectorization
factor. We check the latter before
