And with ox is wrong. As is trying to handle the variable count
case. That is fixing something that is not broke.
Does this look OK? Now movmemhi will only handle positive constant
counts, and FAIL for the other cases (zero, negative or variable) to
let GCC handle them by itself.
Hopefully this is the final version, committed to mainline - 4.0 and
3.4 will follow soon if there are no problems, please test.
Thanks,

[Bug c++/20453] New: GCC fails to treat a valid constant expression as a template argument
This is happening in the compilation of boost::aligned_storage
(boost/aligned_storage.hpp) in the current CVS.
The version of GCC used is 4.0.0 20050309 (prerelease)
I am sorry I can't provide a verified to fail snippet,
since I don't have access to that version of GCC. The
following is an untested attempt to reproduce the
problem in isolated code.
#include cstddef
template
std::size_t size_
, std::size_t alignment_ = std::size_t(-1)
class aligned_storage
{
};
int main()
{
aligned_storage1 as;
}
This produces the following:
'(size_t)((-1))' is not a valid template argument for type 'unsigned int'
because it is a non-constant expression
which AFAICS is an invalid error.

[Bug libfortran/18879] ? not supported in namelist input
--- Additional Comments From paulthomas2 at wanadoo dot fr 2005-03-13 17:59 --- (In reply to comment #2) This is indeed and extension. See http://h18009.www1.hp.com/fortran/docs/lrm/lrm0372.htm#nm_in for the Digital/Compaq/HP specification (In reply to comment #1) Is this a language extension? Seems likely, as the standard has no concept of stdin and stdout. Could you point to someplace where this extension is specified? It's in the comments to io.h (line 76 ff): Even more complex, during the execution of a program containing a namelist READ statement, you can specify a question mark character(?) or a question mark character preceded by an equal sign(=?) to get the information of the namelist group. By '?', the name of variables in the namelist will be displayed, by '=?', the name and value of Also, check out http://h18009.www1.hp.com/fortran/docs/lrm/lrm0372.htm . It's specified in green, which I suppose means that it is an extension. Googling for namelist fortran question mark will lead to other examples. Offhand, I can't find a UNIX compiler that doesn't support it. g77 also tries, but the support there is buggy (see PR 18874). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18879

[Bug c/20464] New: Apparent bug in char comparison
I am running debian sarge in a PowerBook G3, kernel 2.6.8.
When I try to compile this code:
$ cat pp.c
#includestdio.h
main(){
char c=-1;
if(c 0){
printf(hola\n);
}
}
I get this error:
$ gcc pp.c
pp.c: In function `main':
pp.c:7: warning: comparison is always false due to limited range of data type
I have tested it with no trouble in gcc 2.95 (debian woody i386),gcc 3.2.3
(slackware i386), gcc 3.3 (MacOSX, ppc). I have noted that if the comparison is
against 1 ( if(c 0) ... ) the error do not occurs.
This is the output using the -v -save-temps options:
$ gcc -v -save-temps pp.c
