ANTLR v3

Token.UP and Token.DOWN are defined literally to dfaEdge() template

Created: 12/Dec/06 10:09 AM Updated: 22/Dec/06 12:55 PM

Component/s:

ANTLR Core

Affects Version/s:

None

Fix Version/s:

3.0b6

Environment:

Most noticeble in C codegen because i had to come up with a structure that allowd the syntax token.UP in codegen. However this cannot be used in all cases, and I am sur that the other targets will hit this shortly in tree parsers.

Description

« Hide

Calls to the codegen template dfaEdge() occasionally send in the literal text Token.UP (tree parser). Wheneer Token.INVALID Token.EOR Token.DOWN and Token.UP are required, they shuodl be generated via a template, so that their particaul expression in the target codegen can be used, rather than Token.UP.

Made Token.UP plain UP etc... I think that got changed earlier during an over aggressive search/replace. Technically should be a template, but probably ok that some predefined names go out as strings not templates.
