[PATCH bpf-next v1 1/2] selftests/bpf: Add missing system defines for mips

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Update get_sys_includes in Makefile with missing MIPS-related definitions
to fix many, many compilation errors building selftests/bpf. The following
added defines drive conditional logic in system headers for word-size and
endianness selection:

  MIPSEL, MIPSEB
  _MIPS_SZPTR
  _MIPS_SZLONG
  _MIPS_SIM, _ABIO32, _ABIN32, _ABI64
