            Bug ID: 106335
           Summary: struct copies with volatile fields are done using
                    memcpy
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: segher at gcc dot gnu.org
  Target Milestone: ---

struct s { volatile int x[42]; } a;
void f(struct s b) { a = b; }

results in machine code calling memcpy(), which is not valid.
