--- Comment #21 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Gaius Mulley <ga...@gcc.gnu.org>: https://gcc.gnu.org/g:f2872e00f61a5a333fa22e651d37d3b2035ac41f commit r14-8227-gf2872e00f61a5a333fa22e651d37d3b2035ac41f Author: Gaius Mulley <gaiusm...@gmail.com> Date: Thu Jan 18 13:06:30 2024 +0000 PR modula2/111956 Many powerpc platforms do _not_ have support for IEEE754 This patch corrects commit r14-4149-g81d5ca0b9b8431f1bd7a5ec8a2c94f04bb0cf032 which assummed all powerpc platforms would have IEEE754 long double. The patch ensures that cc1gm2 obtains the default IEEE754 long double availability from the configure generated tm_defines. The user command line switches -mabi=ibmlongdouble and -mabi=ieeelongdouble are implemented to override the configuration defaults. Bootstrapped on power8 and power9 machines. gcc/m2/ChangeLog: PR modula2/111956 * Make-lang.in (host_mc_longreal): Remove. * configure: Regenerate. * configure.ac (M2C_LONGREAL_FLOAT128): Remove.
