           Summary: Nios2: Assembler messages with toolchains based on
                    binutils 2.26 and gcc 5.4
           Product: binutils
           Version: 2.26
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils

  Target Milestone: ---

Hi,

The new nios2 toolchain used by Buildroot autobuilders doesn't work due to the
binutils-gcc version being used (binutils 2.26.1 and gcc 5.4).

/tmp/ccexKnYo.s: Assembler messages:
/tmp/ccexKnYo.s:1789: Error: r31 cannot be used with jmp; use ret instead

I've build some nios2 toolchains and it appear that gcc5 require binutils <=
2.25.x on this platform.
If gcc6 is used with binutils 2.26.1, the affected package build fine.

I'm not sure, but do you think this issue may be related to the new Nios2 Gen2
support in Binutils 2.26 and Gcc 6?

Best regards,
Romain
