------- Comment #27 from manfred99 at gmx dot ch 2007-10-12 15:28 -------
With gcc of today (patched tree-ssa-forwprop.c to make it bootstrap):
# gfortran -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gfortran-source/gcc/configure --enable-languages=fortran
--disable-nls --disable-multilib --enable-checking=release
--prefix=/usr/local/gfortran-test
Thread model: posix
gcc version 4.3.0 20071012 (experimental) [trunk revision 129260] (GCC)
The original program works fine now, the bugzilla testcase too, both
with and without "-fforce-addr". I'm not able to trigger this wrong-code
issue with this new version now.
Note: the testcase gives different output, as meanwhile in gfortran the default
precision for outputs has been increased. The actual values are the same
though.
Thanks a lot!
