For the vfw vx format RVV intrinsic, the scalar type _Float16 also
requires the zvfh extension. Unfortunately, we only check the
vector tree type and miss the scalar _Float16 type checking. For
example:
vfloat32mf2_t test_vfwsub_wf_f32mf2(vfloat32mf2_t vs2, _Float16 rs1, size_t v

The trap in the range-op dispatch code is really an internal debugging
aid, and only a temporary one for a few weeks while the dust settles.
This patch turns it off by default, allowing problematic passes to
turn it on for analysis.
gcc/ChangeLog:
* range-op.cc (TRAP_ON_UNHANDLED_POINTER_
The canonical way to indicate that a range operator is unsupported is
to return false, which has the sematic meaning of VARYING. This patch
cleans up a few default virtuals that were trying harder to set
VARYING manually.
gcc/ChangeLog:
* range-op-ptr.cc (range_operator::fold_range): Ret
For the record, we have always returned false (VARYING) for
unsupported range operators. This patch just restores the behavior
we've always had, while adding a knob for further analysis (for
example. IPA which is getting its range types mixed up).

I have pushed a few cleanups to make it easier to move forward without
disturbing passes which are affected by IPA's mixing up the range
types. As I explained in my previous patch, this restores the default
behavior of silently returning VARYING when a range operator is
unsupported in either a par
Fixed the problems and committed to trunk.

I wasn't entirely sure what to do with the 'abi/main.C' testcase here;
is this OK, or should I e.g. lower the linkage error to a pedwarn for
the purposes of this test?
Bootstrapped and regtested on x86_64-pc-linux-gnu, and lightly checked
with a MinGW32 cross. OK for trunk?

Hi,
On some targets it seems that ssize_t is not defined by any of the headers
transitively included by . This leads to a bootstrap fail when jit is
enabled. The attached patch fixes it by include . Other headers in
GCC treat as available on all targets, so we include it
unconditionally.

Overnight testing showed a small number of cases where constant

It was a minor goof in the recent bseti code. In the code to first
figure out what bits LUI could set, I

I recently added the ability to use slli.uw in the synthesis path. That
code was conditional on the right justified constant being a LUI_OPERAND
after sign extending from bit 31 to bit 63.
That code is working fine, but could be improved. Specifically
