Hi,
I can't believe this is a bug, but the test code supplied will not
assemble. Therefore I've sent in a bug report.
UTILITY:
as --version
GNU assembler 2.9.1
Copyright 1997 Free Software Foundation, Inc.
This program is free software; you may redistribute it under the terms of
the GNU General Public License. This program has absolutely no warranty.
This assembler was configured for a target of `i686-pc-linux-gnu'.
PATCHES:
No Patches
MACHINE:
Pc amd duron Linux RedHat 6.1
uname -a
Linux h2pc-13 2.2.12-20 #1 Mon Sep 27 10:40:35 EDT 1999 i686 unknown
BUILT WITH:
gcc --version
2.95.2
COMMAND INVOCATION:
as a.s
OUTPUT PRODUCED:
a.s: Assembler messages:
a.s:3: Error: Rest of line ignored. First ignored character is `*'.
a.s:7: Error: Rest of line ignored. First ignored character is `*'.
a.s:10: Error: Rest of line ignored. First ignored character is `*'.
a.s:11: Error: Rest of line ignored. First ignored character is `*'.
a.s:14: Error: Rest of line ignored. First ignored character is `*'.
a.s:15: Error: Rest of line ignored. First ignored character is `*'.
a.s:16: Error: Rest of line ignored. First ignored character is `*'.
COMMENT:
I belive the output is incorrect as it contradicts the gas manual. The input
file 'a.s' has a selection of 'C' comments all of which should be parsed
successfully without error.
gas manual Section
Comments
========
There are two ways of rendering comments to `as'. In both cases the
comment is equivalent to one space.
Anything from `/*' through the next `*/' is a comment. This means
you may not nest these comments.
/*
The only way to include a newline ('\n') in a comment
is to use this sort of comment.
*/
ExtraNote
I also have a Sun Solaris 7 version of as which successfully parses a.s
Both my binutils were built from the same source files.
