[PATCH] m68knommu: remove useless compiler args
Here is a small patch that made my kernel .text segment shrink by 8k IIRC on my 5272-based board, by removing `-Wa,-S' from CFLAGS. The `-Wa,-S' option prevents `gas' from using short forms of jsr. Without it, `gas' replaces `jsr xxx.l' (6 bytes) by `jsr xxx@pc' (4 bytes) when possible. On 5272, both forms are equally fast. The `-Wa,-m5307' option is useless, because gcc already gives it to `gas' from the `-m5307' option. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
