Hi All,
Ok I found a problem in gcc/expr.c where fold_single_bit_test was returning NULL_TREE and
this was causing expand_expr_real to seg fault,
I put this patch into gcc/expr.c although I expect its a problem in
gcc/fold-expr.c
Any ideas from anyone?
I now have another problem to look into with compiling my code....
Regards,
