Hi,
This is the 4.9 and GCC 5 backport of patch from PR67037 that's already in

I've build it on 4.9 and confirmed that it works.

instead of a declaration at the top of the function. OK with that change.

Sigh, Yeah it is one of those patches. Applied to trunk with the changes.

D'oh! yup, fixed.

The following fixes missed constant folding of __builtin_signbit and
friends. The first issue is that the calls were never detected as
having compatible arguments because the FE builds the function
types in a wrong way (they should be variadic but have 'void',
even multiple!, arguments).

This is the patch I've just committed.
It includes the new target hook overriding, which was originally in patch 3.

forwprop1 cannot handle it (it requires to CSE the two vector initializers
first). fre1 can do that but due to an oversight in gimple_simplify
it didn't.
Fixed thus.

Hi,
Testing boolean vector conversions I found several runtime regressions
and investigation showed it's due to incorrect conversion caused by
unsigned boolean type. When boolean vector is represented as an
integer vector on target it's a signed integer actually. Unsigned
boolean type was chosen
