Max Brunsfeld	e917756ad1	Remove depends_on_lookahead field from parse table entries ... This simplifies the logic for determining whether a token is reusable and makes it more conservative. It should fix some incremental parsing bugs that are being caught by the randomized tests on CI.	2018-03-28 10:58:33 -07:00

Max Brunsfeld	0143bfdad4	Avoid use-after-free of external token states ... Previously, it was possible for references to external token states to outlive the trees to which those states belonged. Now, instead of storing references to external token states in the Stack and in the Lexer, we store references to the external token trees themselves, and we retain the trees to prevent use-after-free.	2017-06-27 14:54:27 -07:00
