| |
Recent MIPS toolchains complain about the use of an immediate larger than 32bits when compiling a 32bit kernel, leading to the following build failure: {standard input}: Assembler messages: {standard input}:131: Error: number (0x9000000080000000) larger than 32 bits {standard input}:154: Error: number (0x9000000080000000) larger than 32 bits {standard input}:191: Error: number (0x9000000080000000) larger than 32 bits
Fix this by specifying registers are 64bit via the .set gp=64 directive.
Since IP22 is the default MIPS machine, this is causing allnoconfig build failures.
