This is the only explanation I have, since GCC does not generate "r3" references in it's assembler code. It would have been a good idea if you had included your source code so we could see what you are doing... > [root@localhost atmlz]# ppc_6xx-gcc -S -o temp.s atm_aalx.c > [root@localhost atmlz]# vi temp.s > ................... > stw 0,4(9) > .L36: > #APP > mfmsr r3 > ori r3,r3,0x8000 > andi. r3,r3,0xffbf > mtmsr r3 > #NO_APP > lwz 11,0(1) > .............................. I see. This is your own assembler code, not something generated from C source code. > I must change those "r3" to "3" manually. > How to fix? Don't write incorrect assembler code, or use the required header files (like ppc_asm.tmpl). And while we are at it: be careful not to try privileged instructions in user space. This is your own error, not a problem with ELDK.
