Re: bootstrap/5888: [sun solaris 2.6] Bootstrap stage 2/3 comparisonfailure gcc-3.0.4

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
