Subject: * src/parse-gram.y (CHARACTER): Remove unused token.
X-Git-Tag: BISON-1_875~319
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/20ef1ad524cad576a133b7b602c8fd6a94f8eae5

* src/parse-gram.y (CHARACTER): Remove unused token.
All uses removed.

* src/scan-gram.l: Remove stack option.  We no longer use the
stack, since the stack was never deeper than 1; instead, use the
new auto var c_context to record the stacked value.

Remove nounput option.  At an unexpected end of file, we now unput
the minimal input necessary to end cleanly; this simplifies the
code.

Avoid unbounded token sizes where this is easy.

(unexpected_end_of_file): New function.
Use it to systematize the error message on unexpected EOF.
(last-string): Now auto, not static.
(YY_OBS_FREE): Remove unnecessary do while (0) wrapper.
(scanner_last_string_free): Remove; not used.
(percent_percent_count): Move decl to just before use.
(SC_ESCAPED_CHARACTER): Return ID at unexpected end of file,
not the (never otherwised-used) CHARACTER.
