The compiler uses MIPS NaN conventions on MIPS; fp-bit knows about those but soft-fp does not. Are you not concerned about that regression? (Is this code only ever going to be used in software floating-point configurations, without exception support, so the choice of NaN doesn't matter much?) libgcc/config/mips/t-mips sets FPBIT and DPBIT. Shouldn't you do something to override those settings? Even if the libgcc logic is to build soft-fp if both soft-fp and fp-bit are configured, it would seem cleaner for the fragments to configure only the relevant one. -- Joseph S.
