I had a look into misc.S and found similar routines (__ashrdi3) there. Then I
searched in the egcs-1.1.2 sources for files, where such functions are
referenced. I found definitions in egcs-1.1.2/gcc/config/rs6000/rs6000.md but
they are not native ppc assembler instructions. As I'm not that much used to
*.md files and ppc assembly code, I'm currently not able to define the missing
function in misc.S myself.
I checked the kernel source diffs from version 2.2.4 to 2.2.6 for lshrdi3 and
had only success for arch=sparc. So, is there anybody who can add the missing
function to misc.S for arch=ppc?
