Floating point check (fchk.s)
the condition flags set by fcmp.s directly. The following mapping from floating point compare
results to AVR32 status register flags is used:
Table 4-1.
Table 4-2.
This instruction checks the operand for special values, such as Not-a-Number (NaN), infinity (inf)
and denormal. Status register flags are set according to the result of the fchk.s instruction. This
instruction is useful since some algorithms require special treatment of these special values. The
floating point approximation instructions updates the status register flags in the same way as
fchk.s, since iterative approximation algorithms require special handling of these special values.
Ordinary AVR32 branch instructions such as breq and conditional instructions such as retge and
movls can use the condition flags set by fchk.s directly.
