GCC wrongly accepts [*] in old-style parameter definitions because
because parm_flag is set on the scope used for those definitions and,
unlike the case of a prototype in a function definition, there is no
subsequent check to disallow this invalid usage. This patch adds such
a check. (At this

When writing vector-length specific SVE code, it's useful to be able
to store an svbool_t predicate in a GNU vector of unsigned chars.
This patch makes sure that there is no overhead when converting
to that form and then immediately reading it back again.
Tested on aarch64-linux-gnu and applied
Now that the C frontend can cope with POLY_INT_CST-length initialisers,
we can make aarch64-sve-acle.exp run the full set of tests. This will
introduce new failures for -mabi=ilp32; I'll make the testsuite ILP32
clean separately.
Tested on aarch64-linux-gnu and applied as r278908.
Richard
This patch reports an error if code tries to use variable-length
SVE types when SVE is disabled. We already report a similar error
for definitions or uses of SVE functions when SVE is disabled.
Tested on aarch64-linux-gnu and applied as r278909.

This recovers some of the nearly dead code in
gimple_fold_builtin_memory_op by allowing a rewrite of memcpy
with a properly aligned source or destination decl. In particular
this handles register typed vars to be tranformed (and later

Together with 1/2 the testcase

The option is -fstack-protector-strong. But what is tested is equally
true for any

Hi!
The OBJ_TYPE_REF constexpr handling looks through DECL_FIELD_IS_BASE
COMPONENT_REFs to find the actual object on which the method is called,
but as the following testcase shows, we need to do the similar thing also

How can this generate pli or pla? If this is something this test tests
for, the comment should say.
