PATCH 1/1 fix compile of denx rtai ppc with gcc 3.3.2

I had a few problems compiling Denx RTAI for ppc with gcc 3.3.2. Attached patches seem to fix this - at least the examples run on my MPC5200. Changes still compile ok on 2.95.4.

For linuxppc_devel patched with patch-denx-linuxppc_2_4_devel-LABEL_2003_12_22_1500-ltt:

Change formatting of __asm__ in ltt_clear_bit to be similar to ltt_set_bit to fix compile error.

For rtai-24.1.12-denx.tar.bz2:

Fix clobber list to fix compile error on gcc 3.3.2.

Thanks for the patches. I'm going to verify and commit them into the RTAI 24.x and 3.x CVS repositories a.s.a.p.

This issue is off-topic on this list. Please send RTAI related mails to [email protected].

Wolfgang.
