Alan Modra 114d3d3070 Mostly cosmetic. Fixes to comments. Don't start as_bad and as_warn
messages with capital.  Don't malign Unixware, malign SysV386 instead.
2000-03-26 14:13:01 +00:00
Alan Modra e53d3a5d95 Extend the i386 gas testsuite to do some tests for intel_syntax. Fix all
the errors exposed by this addition.  These were intel mode
"fi... word ptr", "fi... dword ptr", "jmp Imm seg, Imm offset", "out dx,al".
The failure with intel "out dx,al" was also present in att "out al,dx".
Extend testsuite to catch this case too.
