New implementation for 'tbclist' 2021-03-10T13:27:19+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2021-03-10T13:27:19+00:00 urn:sha1:81c6021fb40a254d9a586b0cb53453bba8973d80 - Fixes a bug, by removing dummy nodes together with the node itself. (The previous implementation could leave dummy nodes in frames which otherwise had no tbc variables, and therefore would not close variables; that could leave 'tbclist' pointing higher than 'top', which could dangle if the stack shrank.) - Computes MAXDELTA based on the type of delta, to ease changing its type if needed. - Instead of 'isdummy', uses 'delta==0' to signal dummy nodes. (Dummy nodes always have MAXDELTA for their real delta.) New implementation for to-be-closed variables 2021-02-09T17:00:05+00:00 Roberto Ierusalimschy roberto@inf.puc-rio.br 2021-02-09T17:00:05+00:00 urn:sha1:4e47f81188d37e29027158b76271d02a781242e2 To-be-closed variables are linked in their own list, embedded into the stack elements. (Due to alignment, this information does not change the size of the stack elements in most architectures.) This new list does not produce garbage and avoids memory errors when creating tbc variables.
