Hi, I'm adding some assembly floating point functions to bfin port. These functions are much faster than those in fp-bit.c. However, they relax some IEEE floating point standard rules for checking inputs against NaN. So I think we'd better to call them only when -ffast-math or -ffinite-math-only is added.
What I want is tell gcc to link specific libgcc-fast-fp.a, which contains these assembly functions if there is -ffast-match or -ffinite-math-only. Otherwise, let gcc link ordinary libgcc.a. Is there any existing target doing this or similar things? Thanks, Jie
