+
+ * TODO: Add pointer to Sylvain Schmitz's work on static detection
+ of potential ambiguities in GLR grammers.
+
+2006-12-12 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * tests/testsuite.at (AT_CHECK): When checking if $1 starts with
+ `bison ', use m4_index instead of m4_substr since chopping up a string
+ containing M4-special characters causes problems here.
+
+ Fix a couple of bugs related to special characters in user-specified
+ file names, and make it easier for skeletons to compute output file
+ names with the same file name prefix as Bison-computed output file
+ names.
+ * data/glr.cc, data/push.c, data/yacc.c: In @output, use
+ b4_parser_file_name and b4_spec_defines_file instead of
+ @output_parser_name@ and @output_header_name@, which are now redundant.
+ * data/glr.c, data/lalr1.cc: Likewise. Also, in header #include's, use
+ b4_parser_file_name, b4_spec_defines_file, and the new
+ @basename(FILENAME@) instead of @output_parser_name@ and
+ @output_header_name@, which inappropriately escaped the file names as
+ C string literals.
+ * src/files.c (all_but_ext): Remove static qualifier.
+ (compute_output_file_names): Move `free (all_but_ext)' to...
+ (output_file_names_free): ... here since all_but_ext is needed later.
+ * src/files.h (all_but_ext): Extern.
+ * src/muscle_tab.h (MUSCLE_INSERT_STRING_RAW): New macro that does
+ exactly what MUSCLE_INSERT_STRING used to do.
+ (MUSCLE_INSERT_STRING): Use MUSCLE_OBSTACK_SGROW so that M4-special
+ characters are escaped properly.
+ * src/output.c (prepare): Define muscle file_name_all_but_ext as
+ all_but_ext.
+ For pkgdatadir muscle, maintain previous functionality by using
+ MUSCLE_INSERT_STRING_RAW instead of MUSCLE_INSERT_STRING. The problem
+ is that b4_pkgdatadir is used inside m4_include in the skeletons, so
+ digraphs would never be expanded. Hopefully no one has M4-special
+ characters in his Bison installation path.
+ * src/scan-skel.l: Don't parse @output_header_name@ and
+ @output_parser_name@ anymore since they're now redundant.
+ In @output, use decode_at_digraphs.
+ Parse a new @basename command that invokes last_component.
+ (decode_at_digraphs): New.
+ (BASE_QPUTS): Remove unused.

+
+ * src/files.c (tr): Change return type to void.
+ * src/muscle_tab.c (muscle_insert): Free storage in case muscle_grow

+ (muscle_find): Return storage instead of value so that

+
+ * bootstrap.conf (excluded_files): Exclude m4/codeset.m4 (undoing

+ * tests/calc.at (_AT_DATA_CALC_Y): fclose the FILE* so Valgrind doesn't
+ complain.
+ * tests/testsuite.at (AT_CHECK): Redefine so that running Bison and
+ expecting a non-zero exit status sets --leak-check=summary and
+ --show-reachable=no for Valgrind. Bison unabashedly leaks memory in

+
+2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
