    • Simplify cst_and_fits_in_hwi · 05ff4c5f 
      While looking at the use of cst_and_fits_in_hwi in tree-ssa-loop-ivopts.c,
I had difficulty working out what the function actually tests.  The
final NUNITS check seems redundant, since it asks about the number of
HWIs in the _unextended_ constant.  We've already checked that the
unextended constant has no more than HOST_BITS_PER_WIDE_INT bits, so the
length must be 1.

I think this was my fault, sorry.

Tested on x86_64-linux-gnu and aarch64-linux-gnu.

	* tree.c (cst_and_fits_in_hwi): Simplify.

    • Add a wi::to_wide helper function · 697e0b28 
      As Richard says, we ought to have a convenient way of converting
an INTEGER_CST to a wide_int of a particular precision without
having to extract the sign of the INTEGER_CST's type each time.
This patch adds a wi::to_wide helper for that, alongside the
existing wi::to_offset and wi::to_widest.

Tested on x86_64-linux-gnu and aarch64-linux-gnu.

    • Support << and >> for offset_int and widest_int · 8de73453 
      Following on from the comparison patch, I think it makes sense to
support << and >> for offset_int (int128_t) and widest_int (intNNN_t),
with >> being arithmetic shift.  It doesn't make sense to use
logical right shift on a potentially negative offset_int, since
the precision of 128 bits has no meaning on the target.

    • Support <, <=, > and >= for offset_int and widest_int · 032c80e9 
      offset_int and widest_int are supposed to be at least one bit wider
than all the values they need to represent, with the extra bits
being signs.  Thus offset_int is effectively int128_t and widest_int
is effectively intNNN_t, for target-dependent NNN.

Because the types are signed, there's not really any need to specify
a sign for operations like comparison.  I think things would be clearer
if we supported <, <=, > and >= for them (but not for wide_int, which
doesn't have a sign).

Tested on x86_64-linux-gnu and aarch64-linux-gnu.

    • [RS6000] Allow saving of fixed regs. · cc5f7354 
      As I noted a long time ago in the comment on fixed_reg_p, the real
problem with saving fixed/global regs is that exception frame
unwinding might restore them.  So don't emit eh_frame info for any
such reg, and the unwinder won't restore them.

Also, tidy rs6000_savres_strategy.  Delaying some checks means we
won't iterate over regs quite so often.

	* config/rs6000/rs6000.c (rs6000_savres_strategy): Force inline
	restoring when fixed_reg_p, but allow out-of-line or stmw save.
	Check for user regs later to avoid unnecessary looping over regs.
	Merge user reg check with non-saved reg check.  Don't force
	inline VR restore when static chain used.
	(rs6000_frame_related): Omit eh_frame info for user regs when
	saving.
	(fixed_regs_p): Delete.

    • [RS6000] Split SAVRES_STRATEGY · 8cd5d1f4 
      No functional change here.  A single bit becomes two bits, which
always have the same value at the moment.

	* config/rs6000/rs6000.c (SAVRES_MULTIPLE): Replace with..
	(SAVE_STRATEGY, REST_STRATEGY): ..this.  Renumber and sort enum.
	Update all uses.
