# This file is used if not configured --with-avrlibc=no
#
# AVR-Libc comes with hand-optimized float routines.
# For historical reasons, these routines live in AVR-Libc
# and not in libgcc and use the same function names like libgcc.
# To get the best support, i.e. always use the routines from
# AVR-Libc, we remove these routines from libgcc.
#
# See also PR54461.
#
#
# Arithmetic:
# __addsf3 __subsf3 __divsf3 __mulsf3 __negsf2
#
# Comparison:
# __cmpsf2 __unordsf2
# __eqsf2 __lesf2 __ltsf2 __nesf2 __gesf2 __gtsf2
#
# Conversion:
# __fixsfdi __fixunssfdi __floatdisf __floatundisf
# __fixsfsi __fixunssfsi __floatsisf __floatunsisf
