xtensa-fsf-ld: dangerous relocation: call8: call target out of range

[Max Filippov]

Hello.

I'm trying to build linux kernel for FSF xtensa core using binutils-2.22.
In the final linking step I get the following error:

+ /home/dumb/ws/tensilica/tools/xtensa-toolchain-build/build-xtensa-fsf-elf/root/bin/xtensa-fsf-elf-ld
--build-id -o .tmp_vmlinux2 -T

net/built-in.o: In function `fib_net_init':
fib_frontend.c:(.init.text+0x1553): dangerous relocation: call8: call
target out of range: (.text+0x3eb38)

If I add --no-relax ld option to this link step everything works fine.

Referenced portion of the object file (net/built-in.o) looks like this:

    1550:       180000          l32r    a8, fffc1550

    1556:       caa3            beqz.n  a10, 157d <fib_net_init+0x5d>

Can anybody suggest the way to debug/fix it?
