--- Comment #6 from Janne Blomqvist <jb at gcc dot gnu.org> --- Author: jb Date: Mon Nov 11 15:59:48 2019 New Revision: 278058 URL: https://gcc.gnu.org/viewcvs?rev=278058&root=gcc&view=rev Log: Bump minimum MPFR version to 3.1.0 Bump the minimum MPFR version to 3.1.0, released 2011-10-03. With this requirement one can still build GCC with the operating system provided MPFR on old but still supported operating systems like SLES 12 (MPFR 3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1). This allows removing some code in the Fortran frontend, as well as fixing PR 91828. ChangeLog: 2019-11-11 Janne Blomqvist <j...@gcc.gnu.org> PR fortran/91828 * configure.ac: Bump minimum MPFR to 3.1.0, recommended to 3.1.6+. * configure: Regenerated. gcc/ChangeLog: 2019-11-11 Janne Blomqvist <j...@gcc.gnu.org> PR fortran/91828 * doc/install.texi: Document that the minimum MPFR version is 3.1.0. gcc/fortran/ChangeLog: 2019-11-11 Janne Blomqvist <j...@gcc.gnu.org> PR fortran/91828 * simplify.c (gfc_simplify_fraction): Remove fallback path for MPFR < 3.1.0.
