And as another reminder, there are bunches of mirrors around the world,
they will pick these files up within the next 24 hours or so.  See the
home page (www.cygnus.com/egcs) for details.

Ok. I will take a look when it is available. I am concerned about
iostream.

The libgstdc++ distribution will _not_ be libg++-2.8.0b6 based,
so you patch is not appropriate.

Could someone please get my libg++ patch at

ftp://ftp.yggdrasil.com/private/hjl/libg++-2.8.0b6-glibc.6.diff.gz

I have tested it on Linux/libc5, Linux/glibc2 and Solaris.

Thanks.

[David S. Miller]

This passed full boostrap and compare, both with and without haifa
enabled, on the sparc-linux-gnulibc1 target.  The testsuite results
were also the same with and without haifa enabled, they are appended
below.

The loop-2f.c failure is very old.  It's a bug in loop invariants
wrt. to comparison operation signedness.  It will crop up on any
target where the stack pointer is a signed negative integer value,
this happens to be the case on 32-bit sparcs.

f (int s, char *p)
{
  int i;
  for (i = s; i >= 0 && &p[i] < &p[40]; i++)
    {
      p[i] = -2;
    }
}

gives:


f:
        !#PROLOGUE# 0
        !#PROLOGUE# 1
        cmp %o0,0
        bl .LL27
        add %o1,40,%g2
        mov -2,%g3
        add %o0,%o1,%o0
        cmp %o0,%g2
.LL32:
        bgeu .LL27
        nop
        stb %g3,[%o0]
        add %o0,1,%o0
        cmp %o0,%o1
        bge .LL32
        cmp %o0,%g2
.LL27:
        retl
        nop

Note how the loop entry test is done (properly) using a signed
conditional branch, however the other test (which is still now on the
integer value, before transformation it was a pointer comparison) uses
an unsigned branch.

I remember the first time I began to hit this with gcc2 snapshots
(about 3/4 of a year ago), I sifted through the loop code in question.
I couldn't for the life of me figure out how gcc made sure that such
transformation made sure that the signedness of comparison and branch
instructions got changed properly.  Can somebody with that code more
fresh in their head tell me how that is supposed to end up happening?

egcs-ss-970821 is available

[Jeffrey A Law]

egcs-ss-970821 is now available in ftp.cygnus.com:/pub/egcs/snapshots.

You'll find:

  egcs-ss-970821.tar.gz 		The full egcs snapshot, including all
					languages and testsuites.

  egcs-core-ss-970821.tar.gz 		The egcs snapshot with all languages,
					but without the testsuites.

  egcs-tests-ss-970821.tar.gz		The egcs testsuite snapshot.

  egcs-ss-970814-970821.diff.gz		Diffs to bring egcs-ss-970814 in
					sync with egcs-ss-970821.  Note that
					this does not include the testsuite!


We're still making changes to the egcs tree layout and snapshot packaging,
so expect things to change in the next snapshot (hopefully by 8/24).  The
next snapshot will include an integrated libstdc++ distribution, texinfo
and maybe other stuff.
