gcc for i386 can be used with the assembly prefix ".code16gcc" to generate 16-bit (real-mode) code. This header file provides the assembly prefix. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

|
* This file is -include'd when compiling 16-bit C code.
|
|
* Note: this asm() needs to be emitted before gcc omits any code.
|
|
* Depending on gcc version, this requires -fno-unit-at-a-time or
|
|
* -fno-toplevel-reorder.
|
|
*
|
|
* Hopefully gcc will eventually have a real -m16 option so we can
|
|
* drop this hack long term.
