Subject: Re:  wrong-code unless -fno-sched-interblock

The problem was detected with gcc-3.4.3 and gcc-3.4.4. I not tested the older
gcc versions. I tested gcc-4.0.1, and the problem on the small sample of code
was not occurs. It is chance (but not certainty) that the problem may be solved
by update gcc. Unfortunately the gcc-4.x generate a little bigger output code
size (about 2-3 percents) and I can not check the all program functionality,
because the 128 kB limit of physical program space of my V850 system was
exceeded. My application is limited strictly by size of physical memory and
using of gcc-3.4.4 is optimal for me for now. Therefore, I can not confirm yet,
whether the gcc-4.x generate correct code - I can not support the confirm via
long-term using of the compiler. The gcc-3.4.4 with -fno-sched-interblock
option works fine (by my opinion).
