Just ignore them or delete gcc-prs from the list of intended recipient.
This is a known problem with GNATS. The message you sent will still
show up in the audit trail after some time if you cc'ed gcc-gnats.

It means that the mailing list reply fields are all screwed up.  You have 
to send messages to gcc-gnats; but the gnats software puts gcc-prs in the 
from field, so automated replies go to the wrong place.... :-(

The "send mail to interested parties" function wants to send mail to the
gcc-prs list (and sometimes java-prs, for Java bugs), but these are
read-only lists.  This is, I believe, a gnatsweb configuration bug,
but in the meantime, I work around the problem by removing the gcc-prs
list from the list of addresses.  As long as gcc-gnats is present and
the subject line doesn't change, your mail will get added to the audit
trail.

Therefore, some tests fail.

Re: failure notice

[G Shyam Sundar]

Hi,
   I am working with a kernel module, which was compiled using GCC
4.X, for x86_64 platform.
   After dis-assembling the module object file, I see that the callq
function is always called with the next instruction of the code as the
target address(based on IP only), as the offset feild following the
instruction "e8"(corresponding to callq) is always 0, instead of the
address of the function where I would think the call should be
actually made to.
   What I want to understand is, how function calls work here? Based
on my understanding, the callq instruction should be followed by a
offset address, so that RIP = RIP + Offset. The offset in my case is
always 0. For the following code, the actual address where
qla2xxx_wake_dpc(pha) starts from is 0x1ac68
C Code:
qla2x00_timer{
                    .....
                    .....
                    test_bit(RELOGIN_NEEDED, &ha->dpc_flags)))
                               qla2xxx_wake_dpc(pha);
       qla2x00_restart_timer(ha, WATCH_INTERVAL);
}

Re: failure notice

[Timothy J. Wood]

  I'm working on the Quake3:Arena port for MacOS X DP4.  This newly released version supposedly contains a compiler based off of gcc 2.95.2 (at least cc -v claims something to that effect).

  The PPC is really poor at converting ints to floats, there is an optimization problem that is making this even worse.  One of the current hot spots in Quake3:Arena exposes this problem under MacOS X DP4.  I don't have a Linux PPC system to test this on unfortunately (maybe I'll reformat my PowerBook to have more partitions in the future :).

  Some code that demonstrates the problem follows.  I'm using doubles in this code to make the example assembly simpler (avoids rounding the double to a float).

---- cast.c ----

double test1(unsigned short *stuff)
{
    unsigned int i;
    double x = 0;
    for (i = 0; i < 1000; i++)
        x += stuff[i];
    return x;
}


double test2(short *stuff)
{
    unsigned int i;
    double x = 0;
    for (i = 0; i < 1000; i++)
        x += stuff[i];
    return x;
}

double test3(char *stuff)
{
    unsigned int i;
    double x = 0;
    for (i = 0; i < 1000; i++)
        x += stuff[i];
    return x;
}

double test4(unsigned char *stuff)
{
    unsigned int i;
    double x = 0;
    for (i = 0; i < 1000; i++)
        x += stuff[i];
    return x;
}


typedef struct _foo {
    unsigned int i:18;
    unsigned int j:14;
} foo;

double test5(foo *stuff)
{
    unsigned int i;
    double x = 0;
    for (i = 0; i < 1000; i++)
        x += stuff[i].i;
    return x;
}

---- end cast.c ----


  I compile this test case with:

	cc -static -O2 -S cast.c

  (the -static avoids a bunch of Mach-O PIC crud that isn't relevant to the problem), I get something like the following:

.const

  There are two problems here.  First, is that the various constants are duplicated for each function (there are more constants for some of the types).  Maybe the linker cleans this up -- I don't know.

  More important is the second problem.  When building the double on the stack, there are two words, one that is constant throughout the loop and one that needs to be updated for each value.  But, gcc doesn't realize that it can avoid rewriting the constant part of the double on each iteration of the loop and in most of the cases above, ends up issuing twice as many store instructions as necessary.

  But in the case of casting unsigned shorts to floats, gcc goes bonkers and ends up doing part of the conversion twice and throwing away the results.

  Can anyone replicate this result on a PPC Linux box with the latest sources?  Either way, hopefully Apple will be able to fix these problems so that their Quake port for MacOS X will run faster :)

Please look at the man page of the socket functions you have used in
your program.  It says you must link in `-lsocket -lnsl', not just
`-lsocket'.
