Re: [MIT-Scheme-devel] bookkeeping memory allocated per primitive

[Arthur A. Gleckler]

Any objections to committing this?

None from me.  This is a clean, simple solution to what initially sounded like a complicated problem.

My only suggestion is to initialize <Free_primitive> to zero explicitly.  That makes it clearer how this test works:

  if (Free_primitive < heap_start)

Otherwise, if someone calls <Primitive_GC> outside of a primitive before any primitive is ever invoked, you're relying on this variable being initialized to zero implicitly in order to detect that condition.
