sim: Factor out NaN handling in floating point operations
2022-02-01 Faraz Shahbazker <fshahbazker@wavecomp.com>
sim/common/ChangeLog:
* sim-fpu.c (sim_fpu_op_nan): New.
(sim_fpu_add): Factor out NaN operand handling with
a call to sim_fpu_op_nan.
(sim_fpu_sub, sim_fpu_mul, sim_fpu_div): Likewise.
(sim_fpu_rem, sim_fpu_max, sim_fpu_min): Likewise.
* sim-fpu.h (sim_fpu_op_nan): New declaration.
