Hi GCCers
i'm trying to add soft-float support for a simple RISC target. I'm not sure what
is the minimal set of (in md file) patterns to add (under a HAS_SOFT_FLOAT
condition or something like that) in order to be able to use the softfloat
emulated instructions.
E.g. the mips only defines "movsf" and "movdf" type patterns.
And about the configuration options, what does
"-with-softfloat-support=internal" exactly do? Does it relate to the
"fp-bit.c", "dp-bit.c" files?
thanks in advance
Kind regards
