In a declaration %token A B, the token A is declared before B, but in %left
A B (or with %precedence or %nonassoc or %right), the token B was declared
before A (tokens were declared in reverse order).
* src/symlist.h, src/symlist.c (symbol_list_append): New.
* src/parse-gram.y: Use it instead of symbol_list_prepend.
* tests/input.at: Adjust expectations.
* src/getargs.c (feature_flag): Here.
* tests/local.at (AT_BISON_CHECK_, AT_BISON_CHECK_NO_XML): Deactivate carets
for the testsuite, by default.
* tests/input.at: Adjust the locations for command line definitions.
This is consistent with the other %define variable names.
* data/java.m4: Use api.value.type instead of stype.
* doc/bison.texi, NEWS: Document that change.
* src/muscle-tab.c (muscle_percent_variable_update): Provide backward
compatibility.
* tests/java.at: Adjust.
* src/gram.c (print_lhs): Use %*s to indent.
* src/print_graph.c (print_lhs): Use obstack_printf.
Became simple enough to be inlined in...
(print_core): here.
Use a "rule*" instead of an index in "rules[]".
* src/location.c (location_caret): finish the line with one whether or not it
is present in input. Rewrite code without getline.
(cleanup_caret): Reset the caret_info global.
* bootstrap.conf: No longer require getline.
Unput was no longer used since a POSIX-compatiblity issue with Flex 2.5.31,
which has been adressed in newer versions of Flex. See this discussion:
<http://lists.gnu.org/archive/html/bug-bison/2003-04/msg00029.html>
This partially reverts commit aa4180418f.
* src/scan-gram.l (unexpected_end): Here.
* tests/input.at: Adjust for new order of error reports.
* src/tables.c (save_column, pack_vector): Reduce the scope to
emphasize the structure of the code.
Rename the returned value "res" to make understanding easier.
* src/muscle-tab.c (define_directive): Be robust to "assignment"
containing '='.
(muscle_percent_variable_update): Upgrade "variant" to "api.value.type".
Support such upgrade patterns.
Adjust callers.
* data/bison.m4: Use api.value.type for variants.
* tests/c++.at: Adjust tests.
Instead of
warning: deprecated %define variable name: 'namespace', use 'api.namespace' [-Wdeprecated]
display (in -fno-caret mode):
warning: deprecated directive: '%define namespace foo', use '%define api.namespace foo' [-Wdeprecated]
and (in -fcaret mode):
warning: deprecated directive, use '%define api.namespace toto' [-Wdeprecated]
%define namespace toto
^^^^^^^^^
This is in preparation of cases where not only the variable is
renamed, but the values are too:
warning: deprecated directive: '%define variant', use '%define api.value.type variant' [-Wdeprecated]
* src/muscle-tab.c (define_directive): New.
(muscle_percent_variable_update): Take the value as argument, and use it
in the diagnostics.
Loop with a pointer instead of an index.
* tests/input.at (%define backward compatibility): Adjust.
Improve the output by ensuring a well defined order for type switches.
* src/uniqstr.h: Style changes for macro arguments.
(UNIQSTR_CMP): Replace by...
(uniqstr_cmp): this.
* src/uniqstr.c (uniqstr_cmp): New.
Produce well defined results.
* src/output.c: Use it.
* src/symlist.c (symbol_list_free): Deep free it.
* src/symtab.c (symbols_free, semantic_types_sorted): Free it too.
(symbols_do, sorted): Call by address.
* data/glr.c, src/graphviz.h, src/ielr.c, src/scan-gram.l,
* src/system.h, tests/actions.at, tests/glr-regression.at: Do not
use // comments.
Do not introduce variables after statements.
Provide "main" with a return value.
* origin/maint:
