The 3.0 branch has been discontinued. Do you know whether

Hi
bug 5888 and 6193 seem resolved since gcc-3.1 and gcc-3.1.1,
as reported (see http://gcc.gnu.org/ml/gcc/2002-05/msg02737.html).
About a month ago, you already asked the same question,
and as a result closed 5888 (see correspondence included below).
As mentioned in bug 6193, this was a duplicate of 5888,
which I had to re-submit because of more information available
(i.e. responsibility of -funroll-loops), since I could't add additional
info to bug 5888 in gnatsweb (by the way, on other bug-sites, i can add
additional comments at least for bugs submitted by myself... ;-)
Have not tested gcc-3.2 yet, though (but since 3.1 works and
hopefully there's no regression...)
Thanks for the query anyway, and good luck
Arto

This is a rather old bootstrap failure. Can you please check
whether this still happens with newer versions of gcc and
report back to us what you find?
Thanks

Hi
no, it doesn't happen anymore with 3.1 and 3.1.1
(and I have reported it :-) see http://gcc.gnu.org/ml/gcc/2002-05/msg02737.html).
However, I wish to recall my other suggestion again:
with "gcc -v", the compiler flags used for the bootstrap
should be reported together with the other configuration
parameters. This would not only be useful as a requirement
for bug reporting, but also in "real life" when identifying
a particular compiler build. Example: I once for test purposes
bootstrapped with -ffast-math, which naturally leads to certain
floating point anomalies in programs compiled with the resulting
compiler. Somehow, I forgot and actually used that compiler,
leading to errors very difficult to debug, especially since
gcc -v didn't show anything wrong. Also, bootstrapping options
like -O3 -mcpu=ultra etc. might be relevent when transporting
the build to another machine (pre-ultrasparc, for example).
Please let gcc -v report ALL relevant configuration parameters,
including bootstrapping options!
Arto
