--- Comment #5 from Tom de Vries <vries at gcc dot gnu.org> ---
> Switch conversion triggers for this example, which introduces
> a function static var,
Hmm, that was my impression from PR84592 comment 5, and the comments in
tree-switch-conversion.c.
When I compile this example, the only relevant difference I can observe is
DECL_CONTEXT:
...
static int a;
void
foo (void)
{
static int b;
}
...
For variable a, DECL_CONTEXT starts out NULL, and then becomes the translation
unit decl during parsing. For variable, DECL_CONTEXT is foo.
When I debug an example that triggers switch conversion the DECL_CONTEXT for
CSWTCH.x is NULL, and remains like that.
So, in the end, I'm not quite sure whether I can say that CSWTCH.x is a file or
function scope static.
