+# Targets using soft-fp should define the following variables:
+#
+# softfp_float_modes: a list of soft-float floating-point modes,
+# e.g. sf df
+# softfp_int_modes: a list of integer modes for which to define conversions,
+# e.g. si di
+# softfp_extensions: a list of extensions between floating-point modes,
+# e.g. sfdf
+# softfp_truncations: a list of truncations between floating-point modes,
+# e.g. dfsf
+#
+# Extensions and truncations should include those where only one mode
+# is a soft-float mode; for example, sftf where sf is hard-float and
+# tf is soft-float.
+#
+# If the libgcc2.c functions should not be replaced, also define:
+#
+# softfp_exclude_libgcc2 := y
+#
+# Avoiding replacing the libgcc2.c functions is a temporary measure
+# for targets with both hard-float and soft-float multilibs, since
+# these variables apply for all multilibs. With toplevel libgcc,
+# soft-fp can be used conditionally on the multilib instead.
+#
+# If the code should not be compiled at all for some multilibs, define:
+#
+# softfp_wrap_start: text to put at the start of wrapper source files,
+# output with echo
+# e.g. '#ifndef __powerpc64__'
+# softfp_wrap_end: text to put at the end of wrapper source files,
+# e.g. '#endif'
+#
+# This is another temporary measure.
