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 several other sources
is break by internal compiler error in schedule_block referencing at
sched-rgn.c:2572 or haifa-sched.c:2355.
I send you two selected problematic sources including command line and compiler
response in attachment for analyse. But, the compilation of internal gcc
library gcc-3.4.4/gcc/libgcc2.c is affected by the internal error also,
compilation of cross-compiler ends with error:
---- My commandline for cross-compiler make:
../gcc-3.4.4/configure --prefix=/usr/local/v850 --host=i586-pc-linux-gnu\
--target=v850-linux-elf --program-suffix=.v
nice make -s
---- and the error response at end of compilation:
../../gcc-3.4.4/gcc/libgcc2.c: In function `__addvdi3':
../../gcc-3.4.4/gcc/libgcc2.c:109: internal compiler error: in schedule_block,
at haifa-sched.c:2355
I thank you for your help. I presume, that the error resolving is important for
other platform that v850 (may be for any platform with cc0 ?) and may impact
the wide quantity of GCC users. But your first patch has unneded side effect in
internal compiler errors and I ask you kindly for continue of the problem
elimination.
Regards
Libor
