compiling glibc-2.3.1 with gcc-3.2.1 for pentium >= II

compiling glibc-2.3.1 with gcc-3.2.1 for pentium >= II

[Rene Rebe]

Hi all.

When we try to compile the glibc-2.3.1 with gcc-3.2.1 (unpatched
vanilla sources) it fails for optimizations >= pentium2

Here is the error output:

debug-glibc:[signal]# make
(echo '#include <sysdep.h>'; \
 echo 'PSEUDO (__kill, kill, 2)'; \
 echo ' ret'; \
 echo 'PSEUDO_END(__kill)'; \

Hi again.

Further review:

It is a gcc issue, since a Athlon optimised gcc-3.2.1 is able to
compile the same preprocessed file ...

It's very unlikely to be a GCC issue.  You're feeding GCC an assembly
source file, and it's the assembler that is complaining about ignored
characters.  It could be a problem in the preprocessor, for sure, but
then you'd have to save the preprocessed assembly generated by a
working and broken preprocessor and compare them for the bug report to
be useful.

... meaning that you should look at code that is #ifdefed out on the
Athlon.  This *is* sysdep.h, after all.

Grep for __i686 in the input to GCC, then note that __i686 is a macro.

Re: compiling glibc-2.3.1 with gcc-3.2.1 for pentium >= II

[Rene Rebe]

Hi.

Yes - thanks. We already found out and a quick fix is:

+/* __i686 is used in assembler code below as normal text within a statement.
+   When optimizing for pentium2 or pentium3, gcc defines __i686 as cpp macro
+   which destroys the code below. Glibc is only using the cpp macro __i686__,
+   so we can savely undefine __i686 here. - Clifford Wolf */
+#undef __i686

Clifford, have you  already sent the mail to glibc-bugs mailing-list?

No it isn't.  

The problem is that when optimizing for i686, you'll find that
the moral equivalent to

#define i686 1

is in scope, and that one of the sysdep macros is using that
symbol, and *not* expecting it to be defined to anything.

This might be a glibc bug; see PR 8948.  gcc has had an __i686 macro for
years; searching sysdep.h for __i686 might bring enlightenment.
