Bug ID: 101946
Summary: crosscompilation of the kernel for MIPS fails
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: sudipm.mukherjee at gmail dot com
Target Milestone: ---
With "gcc version 11.2.1 20210816 (GCC)" the kernel build for mips
decstation_r4k_defconfig fails with the error:
arch/mips/dec/prom/locore.S: Assembler messages:
arch/mips/dec/prom/locore.S:29: Error: opcode not supported on this processor:
r4600 (mips3) `rfe'
The last gcc version I tried was "gcc version 11.1.1 20210723 (GCC)" and that
has worked with this particular config.
Output from "mips-linux-gcc -v":
Using built-in specs.
