    • PR 78534, 83704 Large character lengths · 6b271a2e 
      This patch fixes various parts of the code to use a larger type than
int for the character length. Depending on the situation,
HOST_WIDE_INT, size_t, or gfc_charlen_t is appropriate.

Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu.

    • [ARM] Fix test fail with conflicting -mfloat-abi · 0e32449b 
      This patch fixes my earlier test case that fails for arm-none-eabi
with explicit user option for -mfloat-abi which conflict with
the test case options. I have added a guard to skip the test
on those cases.

    • [arm] Make gcc.target/arm/copysign_softfloat_1.c more robust · dececdaa 
      This test has needlessly restrictive requirements. It tries to force a soft-float target and tries to run.
This makes it unsupportable for any non-soft-float variant.
In fact, the test can be a run-time test for any target, and only the scan-assembler tests are specific to
-mfloat-abi=soft. So this patch makes the test always runnable and makes the scan-assembler checks predicable
on the the new arm_sotftfloat effective target check. 

	* doc/sourcebuild.texi (arm_softfloat): Document.

	* lib/target-supports.exp (check_effective_target_arm_softfloat):
	New procedure.
	* gcc.target/arm/copysign_softfloat_1.c: Allow running everywhere.
	Adjust scan-assembler checks for soft-float.

    • Fix vect_def_type handling in x86 scatter support (PR 83940) · 929b4411 
      As Jakub says in the PR, the problem here was that the x86/built-in
version of the scatter support was using a bogus scatter_src_dt
when calling vect_get_vec_def_for_stmt_copy (and had since it
was added).  The patch uses the vect_def_type from the original
call to vect_is_simple_use instead.

However, Jakub also pointed out that other parts of the load and store
code passed the vector operand rather than the scalar operand to
vect_is_simple_use.  That probably works most of the time since
a constant scalar operand should give a constant vector operand,
and likewise for external and internal definitions.  But it
definitely seems more robust to pass the scalar operand.

The patch avoids the issue for gather and scatter offsets by
using the cached gs_info.offset_dt.  This is safe because gathers
and scatters are never grouped, so there's only one statement operand
to consider.  The patch also caches the vect_def_type for mask operands,
which is safe because grouped masked operations share the same mask.

That just leaves the store rhs.  We still need to recalculate the
vect_def_type there since different store values in the group can
have different definition types.  But since we still have access
to the original scalar operand, it seems better to use that instead.

	than the vector operand to vect_is_simple_use when handling
	second and subsequent copies of an rhs value.
