# e.g. sf df
# softfp_int_modes: a list of integer modes for which to define conversions,
# e.g. si di

# softfp_truncations: a list of truncations between floating-point modes,
# e.g. dfsf
# softfp_machine_header: the target sfp-machine.h file (relative to config/),
# e.g. rs6000/sfp-machine.h
#
# Extensions and truncations should include those where only one mode
# is a soft-float mode; for example, sftf where sf is hard-float and

# output with echo
# e.g. '#ifndef __powerpc64__'
# softfp_wrap_end: text to put at the end of wrapper source files,
# e.g. '#endif'
