Hi All, I reported this initially in gcc bugzilla thinking it to be a bug with the gcc update. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101946) but it was actually caused by updating to binutils-2_37 from binutils-2_36_1.
To give more context, 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' Both the binutils version has similar configuration: --target=mips-linux' '--prefix=/src/local' '--enable-64-bit-bfd' '--disable-nls' '--disable-werror' '--disable-gdb' 'target_alias=mips-linux Please do let me know if you need any additional information or to test any patch and I will be happy to help. -- Regards Sudip
