From 3f787bff45e1880044e6ab3900b6a40214ae905f Mon Sep 17 00:00:00 2001 From: Philipe De Muyter Date: Tue, 27 Jun 2006 12:47:00 +1000 Subject: [PATCH] [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.
