[PATCH] Fortran: make IEEE_CLASS recognize signaling NaNs

Hi, This is the first part of a three-patch series to fix PR 82207 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82207), making gfortran handle signaling NaNs. This part fixes the library code implementing IEEE_CLASS, by using the issignaling macro (from TS 18661-1:2014) to check whether a NaN

[PATCH] Fortran: fix PR103390, ICE in gimplification

This patch is for PR103390. For background on this issue, the Fortran standard requires that, when passing a non-contiguous array from Fortran to a BIND(C) function with the CONTIGUOUS attribute on the corresponding dummy argument, the compiler has to arrange for it to be copied to/from a cont

[power-iee128] How to specify linker flags
