Hello! Joseph, is there any support for underflow control in soft-fp library? >From a private correspondence with FX about implementing gfortran IEEE support for extended modes, soft-fp that implements 128bit support on x86 could read this setting from FPU control registers and handle denormals accordingly.
This would complement existing SSE handling of 32bit and 64bit FP values and would probably have non-negligible effect on soft-fp performance. Uros.
