By changing code16gcc.h from a C header to an assembly header and use the -Wa,... option to gcc to force it to be added to the assembly input, we can avoid the problems with gcc reordering code bits on us. If we have -m16, we still use it, of course. Suggested-by: Kevin O'Connor <kevin@koconnor.net> Signed-off-by: H.

# This file is added to the assembler via -Wa when compiling 16-bit C code.

# This is done this way instead via asm() to make sure gcc does not reorder

# gcc 4.9+ has a real -m16 option so we can drop this hack long term.
