I wonder why you restrict this to VECTOR_INTEGER_TYPE_P - for
TYPE_PRECISION == 1 type this should work, too.


If TYPE_PRECISION == 1, wouldn't it be better to turn BIT_NOT_EXPR into
TRUTH_NOT_EXPR? Then it will be handled by fold_truth_not_expr.

Hmm, not sure - on GIMPLE we are no longer having the TRUTH_* tree
codes, so we don't want to fold BIT_* to TRUTH_*.

!
I had never noticed that...

Also there should
never be a comparison resulting in a non-integer vector type, no?


Yes, I was going to write VECTOR_TYPE_P, and adding integer seemed more
explicit, but I can go back.

Works for me.

Btw, splitting this out to a helper would be nice.


Called fold_truth_not_expr? Oups ;-)
fold_truth_invert? fold_invert_truth?

Well, fold_invert_truthvalue maybe?  Inverting a truthvalue is well-defined
for vectors and non-vectors and is more appropriate spelling for GIMPLE
where we don't have any TRUTH_NOT_EXPR anymore.

Here is what I tested during the night, I'll just rename the function.
I took the chance to remove an unnecessary alternative in TRUTH_XOR_EXPR.

Passes bootstrap+testsuite on x86_64-linux-gnu.
