Convert gas/config/tc-m68k.c to C90
- From: Andreas Schwab <schwab at suse dot de>
- To: binutils at sources dot redhat dot com
- Date: Sun, 11 Jul 2004 17:21:10 +0200
- Subject: Convert gas/config/tc-m68k.c to C90
Tested by building and testing cross assemblers for m68k-linux, m68k-coff
and m68k-linuxaout and committed as obvious.
Andreas.
2004-07-11 Andreas Schwab <schwab@suse.de>
* config/tc-m68k.c: Convert to C90. Remove redundant
declarations. Indentation fixup.
[M68KCOFF]: Include "obj-coff.h" instead of declaring
obj_coff_section ourselves.
