Mark,

You mentioned these two exclusive ABIs a couple days ago. If you want to compile the toolchain and the kernel correctly to insure run-time compatibility (in my case for 8xx), would you do this

for kernel fp emulation
compile kernel with CONFIG_MATH_EMULATION=y, (do you use -msoft-float while compiling kernel?)
then compile the toolchain without -msoft-float

or

for soft-floating point - no kernel emulation
compile kernel CONFIG_MATH_EMULATION is not set (do you use -msoft-float while compiling kernel?)
then compile the toolchain with -msoft-float


Very very curious
Thanks
Craig
