Re: [PATCH] crosstool-0.42+NPTL-khem vs nyet-ppc860 - fpu/soft-float problems

[Nye Liu <nyet at mrv dot com>]

thanks. i will defintely try this.

unfortunately, for now, it seems i didn't get things right after all.
Im not using in-kernel floating point emulation, so:

1) soft-float seems to be broken.
2) there appear to be FPU instructions in my built glibc

should i add -mcpu=860 and/or -msoftfloat to TARGET_CFLAGS?

should that even be necessary, considering my build target is 860?

is --disable-multilib a problem? without it, should glibc be building
nof libraries only, or is there something else i need to do?

TIA
