Based on Jakub's and Yair's comments I created a new attribute "inrange".
Inrage takes three arguments, pos min and max.
Pos being the argument position in the function, and min and max defines the
range of valid integer. Both min and max are inclusive and work with enums.

No. As stated in other comments, it still reproduces with a longer string (or
with -D_GLIBCXX_USE_CXX11_ABI=0).

This patch extends the recent and;cmp to not;test optimization to also
perform this transformation for TImode on TARGET_64BIT and DImode on -m32,
One motivation for this is that it's a step to fixing the current failure
of gcc.target/i386/pr65105-5.c on -m32.
A more direct benefit for x86_64 is

Hi Uros,
Many thanks for your speedy review. This revised patch implements
all three of your recommended improvements; the use of

Hi,
This patch replaces shift and ior insns with one rotate and mask
insn for the split patterns which are for DI byte swap on Power6 and
before. The test cases shows the optimization.
Bootstrapped and tested on ppc64 Linux BE and LE with no regressions.
Is this okay for trunk? Any
