            Bug ID: 121414
           Summary: aarch64: streaming & streaming-compatible functions
                    should be marked as variant PCS
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Keywords: aarch64-sme, wrong-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rsandifo at gcc dot gnu.org
  Target Milestone: ---
            Target: aarch64*-*-*

For:

void f() __arm_streaming_compatible {}
void g() __arm_streaming {}

f and g were supposed to be marked as STO_AARCH64_VARIANT_PCS, since they do
not conform to the base PCS.  Wilco pointed out that this wasn't done.
