Denormals and underflow control (gradual vs. aburpt) in soft-fp library


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.
