Hi Nick,
I tested the pathed compiler nearly two weaks. I not detect any problem or any
side-effect. Therefore, the bug seems to be fixed reliably. The patch is usable
and needful for next version gcc-3.4.5 too (I te

Hi Nick,
the patched compiler works OK and cross-compiled program in target v850
platform seems to be functional and stable. I assume, the problem is solved,
but I plane to make a thorough p

Hi Libor,
Oops- there was a condition where the new code could walk backwards into a

should not fall into this trap. It certainly works with the

Hi Nick,
I tested patched compiler on my problematic sources and I check assembler
output of compiler carefully (but not execute destination code yet). I believe
that reported problem is solved. But the compilation of

Hi Libor,
I have uploaded a patch which should fix the problem. It is not the most
elegant solution but I believe that it should work for now.
The patch amends the code in add_branch_dependencies() which searches bac

The problem was detected with gcc-3.4.3 and gcc-3.4.4. I not tested the older

Are you seeing the same problem with more recent compilers, like GCC 4.0 or a
