Francois-Xavier Coudert 4637a1d293 Fortran: F2018 rounding modes changes ... Add the new IEEE_AWAY rounding mode. It is unsupported on all known targets, but could be supported by glibc and AIX as part of the C2x proposal. Testing for now is minimal. Add the optional RADIX argument to IEEE_SET_ROUNDING_MODE and IEEE_GET_ROUNDING_MODE. It is unused for now, because we do not support radices other than 2. 2022-08-31 Francois-Xavier Coudert <fxcoudert@gcc.gnu.org> gcc/fortran/ * libgfortran.h: Declare GFC_FPE_AWAY. gcc/testsuite/ * gfortran.dg/ieee/rounding_2.f90: New test. libgfortran/ * ieee/ieee_arithmetic.F90: Add RADIX argument to IEEE_SET_ROUNDING_MODE and IEEE_GET_ROUNDING_MODE. * config/fpu-387.h: Add IEEE_AWAY mode. * config/fpu-aarch64.h: Add IEEE_AWAY mode. * config/fpu-aix.h: Add IEEE_AWAY mode. * config/fpu-generic.h: Add IEEE_AWAY mode. * config/fpu-glibc.h: Add IEEE_AWAY mode. * config/fpu-sysv.h: Add IEEE_AWAY mode.		2022-09-19 13:03:28 +02:00
