Hello,
This patch adds support to fold_unary_loc for one-bit precision
typed bitwise-not expression.
ChangeLog
2011-07-13 Kai Tietz <ktietz@redhat.com>
* fold-const.c (fold_unary_loc): Add
support for one-bit bitwise-not optimizeation.
Bootstrapped and regression tested with prior patches of this series
for x86_64-pc-linux-gnu.
Ok for apply?
Regards,
Kai
