Bug ID: 92463
Summary: Cleanups due to minimum MPFR version bump to 3.1.0
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: jb at gcc dot gnu.org
Target Milestone: ---
As part of resolving PR 91828, the minimum MPFR version required to build GCC
was bumped to 3.1.0 from the previous 2.4.0.
This enables a bunch of cleanups, mostly in the Fortran frontend (hence
assigning this bug to the fortran component).
From https://gcc.gnu.org/ml/gcc-patches/2016-04/msg01544.html :
> For example, you could justify a move to requiring MPFR 3.0.0 or later
with cleanups to use MPFR_RND* instead of the older GMP_RND*, and
similarly mpfr_rnd_t instead of the older mp_rnd_t and likewise mpfr_exp_t
and mpfr_prec_t in fortran/. You could justify a move to requiring MPC
1.0.0 (or 1.0.2) by optimizing clog10 using mpc_log10. I don't know what
if any newer GMP interfaces would be beneficial in GCC. And as always in
such cases, it's a good idea to look at e.g. how widespread the newer
versions are in GNU/Linux distributions, which indicates how many people
might be affected by an increase in the version requirement.
