This patch tests various shared clauses with SVE types. It also adds a test

* gcc.target/aarch64/sve/omp/aarch64-sve-omp.exp: New scaffold.
Hopefully Jakub can comment on whether we should test this in the
GCC testsuite or libgomp testsuite.
On the test:
[...]
+int
+main ()
+{
+ svint32_t x = svindex_s32 (0 ,1);
+ svint32_t y = svindex_s32 (8, 1);
+ svint32_t a, b;
+ svbool_t p;
+
+ /* Implicit shared. */
+ a = foo (x, y, p);
+ b = implicit_shared_default (x, y, p);
It looks like p is used uninitialised here. Can you check locally
that using svptrue_b8 () (or whatever) as an initialiser allows the
test to pass while svpfalse_b () causes it to fail?
Oops, thanks for spotting that. Now verified - will wait for Jakub's
comment on tests' home before I respin.
Thanks,
Tejas.
Thanks,
Richard
