I used ColdFire GCC compiler from your CVS tree, version 3.4.0.
Attached C source generated error. Sorry for length of attached
code, but I failed when trying to generate code snippet manifesting
the bug (one disappeared when shortening the file).

Note: Sorry for misleading info, but 3.3.3 works well, only
3.4.0 and 3.4.1 generate the bug.

shell command follows :

[root@honza bug]# /usr/m68k-elf-3.4.0/bin/m68k-elf-gcc -O2 -m528x -c \
-I./Include -o ./loader.o ./loader.c
/root/tmp/ccXoLYOB.s: Assembler messages:
/root/tmp/ccXoLYOB.s:1429: Error: operands mismatch -- statement
`sub.l #__SDRAM,-516(%a6)' ignored

Attachment: bug.tgz
Description: Unix tar archive
