Description romain.naour 2016-10-08 11:24:25 UTC 
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
