Use mpfr in predict.c instead of sreal, and in mcf.c instead of host double

This completely untested patch shows what I'd like to do: Use mpfr instead of
sreal and host double. Comments on the approach welcome.

Heh, with my patch (with some further changes) I get failures like this one:
../../trunk/gcc/sel-sched-ir.c:6253:1: error: caller edge frequency 38613 does
not match BB frequency 38610

Excess precision? :-)

Use mpfr in predict.c instead of sreal, and in mcf.c instead of host double

Bootstrapped&tested on x86_64-unknown-linux-gnu. Can be queued for GCC 4.7 if
the Powers That Be agree this is the right approach.

The mcf.c parts can be posted separately for GCC 4.6 if necessary, but I
propose to close this big as WONTFIX for older releases.

--- Comment #7 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-01-20 12:38:42 UTC ---
OTOH, nowadays all(?) host platforms we support have IEEE enough compliant
HW floating-point (well, details like signed zeros and NaNs/Infs are not
really relevant for GCC) that a hwfloat.h could provide a mapping to
a 32bit / 64bit IEEE float format?

Else the patch certainly looks good to me, but lets queue it for 4.8
(I remembered you posted patches to remove sreal.c, did you?)

Is there already a meta bug for patches queued for 4.8?

--- Comment #23 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Note that with the introduction of profile-count.h I chased away most of uses
of double for profile calculation. In predict.c we have last occurence when
combinindg probabilities from predictors:

          combined_probability = (((double) combined_probability) * probability 
                                  * REG_BR_PROB_BASE / d + 0.5);                

These are still REG_BR_PROB_BASE based (unlike rest of code that uses
profile_probability datatype) since that was easier to have in .def file.

Cast to double is there only to get type wide enough for REG_BR_PROB_BASE third
power in the 32bit x86 era. It is set to 10000 that is roughly 2^14 so 43 bits
(with sign bits) is enough that should be good for all reasonable double
implementations. However we could easily change it to int64_t.

While looking into PR 45272, I noticed it depends on the host double which is
wrong, we should not depend on that.  The main reason is because different
hosts could produce slightly different results depending on the behavior of
float.

Oh Second mcf_sqrt depends on IEEE FP single precision.

Should use sreal, then?

------- Comment #2 from jakub at gcc dot gnu dot org  2010-08-24 15:42 -------
Well, we don't have sreal_sqrt, and the approximation mcf_sqrt uses is quite
tied to the float representation, while it isn't impossible to convert it, I'd
say it isn't trivial either.  Perhaps we could use mpfr instead.
