            Bug ID: 124698
           Summary: bpf: support stack arguments
           Product: gcc
           Version: 16.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

This bugzilla is for tracking the design and GCC side implementation of the
ability of passing stack arguments on the stack in BPF.  This is the
corresponding LLVM thread/PR:

  https://github.com/llvm/llvm-project/pull/189060

The main motivation for this is to be able to passs more than five arguments in
function calls, which is currently a severe limitation in the target.
