Re: [fortran, patch] IEEE intrinsic modules (ping)

No, we don’t hardcode any values (unless I misunderstand what you are saying). Look at libgfortran/config/fpu-sysv.h get_fpu_rounding_mode() and set_fpu_rounding_mode(): we have two switches, to translate between the GFC_FPE_* values and the FP_R* values. So this should work, really.

The only thing I can see is that libgfortran/config/fpu-sysv.h assumes that FP_RM and others are macros, checking them with "#ifdef FP_RM”. Is that the reason?
If so, we might just want to use them unconditionally… unless it creates a mess on some other SysV target!
