Hi Nicolas, Thanks for the feedback, the error still remains with gcc 10.2.0:
$ make CROSS_COMPILE=/home/nfs/0day/gcc-10.2.0-nolibc/arc-elf/bin/arc-elf- ARCH=arc M=drivers/net/can
WARNING: Symbol version dump ./Module.symvers
is missing; modules will have no dependencies and modversions.
CC [M] drivers/net/can/dev.o
{standard input}: Assembler messages:
{standard input}:1172: Error: inappropriate arguments for opcode 'mpydu'
make[1]: *** [scripts/Makefile.build:280: drivers/net/can/dev.o] Error 1
make: *** [Makefile:1624: _module_drivers/net/can] Error 2
Can somebody help with this problem?
Best Regards,
Rong Chen
