Fork

One last tweak before we move onto the new world/branch.

From-SVN: r259404

allow kind_type for a constructor with integers

From-SVN: r259376

Rewrite size_must_be_zero_p with irange infrastructure.

Rewrite size_must_be_zero_p with irange infrastructure. Previous
implementation did not get the bits in [7fff,ffff]. This fixes a
handful of regressions.

From-SVN: r259370

single_import changes by Andrew to fix my backwards threaders problems.

From-SVN: r259365

make get_operand virtual, move logical and folding into stmt

From-SVN: r259332

Reduce range_stmt to a single gimple stmt for efficiency

From-SVN: r259304

Implement intersect_mask to perform an intersection of a range with a bitmask.

From-SVN: r259236

Add logical AND folding support, and do empty range check in fold(), otherwise we can never be sure of the required range type of the folded exprression

From-SVN: r259173

disable rvrp for these VRP tests

From-SVN: r259172

if we dont get a value for path_range_of_stmt, use range of type

From-SVN: r259171

turn off rvrp too

From-SVN: r259084

disable rvrp for this test as well

From-SVN: r259076

Check in initial version of Early Ranger VRP
disable with -fno-rvrp

From-SVN: r259033

Rewrite range union

From-SVN: r259017

Dont wind back thru divide yet

From-SVN: r258999

Dont create range from nonzerobits

From-SVN: r258990

Dont check invalid ssa names, like floats

Merge remote-tracking branch 'origin/trunk' into range-gen3-merge

This merge has not been tested apart from building c/c++ with
--disable-bootstrap.

get_nonzero_bits_as_range() needs to be looked at.

This PR shows that we get the load/store_lanes logic wrong for arm big-endian.

It is tricky to get right. Aarch64 does it by adding the appropriate lane-swapping
operations during expansion.

I'd like to do the same on arm eventually, but we'd need to port and validate the VTBL-generating
code and add it to all the right places and I'm not comfortable enough doing it for GCC 8, but I am keen
in getting the wrong-code fixed.
As I say in the PR, vectorisation on armeb is already severely restricted (we disable many patterns on BYTES_BIG_ENDIAN)
and the load/store_lanes patterns really were not working properly at all, so disabling them is not
a radical approach.

The way to do that is to return false in ARRAY_MODE_SUPPORTED_P for BYTES_BIG_ENDIAN.

Bootstrapped and tested on arm-none-linux-gnueabihf.
Also tested on armeb-none-eabi.
