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 ** Sent via the linuxppc-embedded mail list.
