[patch tree-ssa-forwprop]: Improve binary and/or/xor folding

2011-06-22 Thread Kai Tietz
Hello, This patch improves via type-sinking folding of binary and, or, and xor operations. First we do sinking also for compatible types with same precision, as those don't need to be preserved for these operations. Additional try to fold patterns (TYPE) X bin-op (Y CMP Z) and (TYPE) X bin-op !Y,
