`%define push_pull "push"' and `%define push_pull "both"'. `%define push_pull "pull"' is the default. * doc/bison.texinfo (Push Decl, Push Parser Function, Pull Parser Function, Parser Create Function, Parser Delete Function): Update declarations. (Decl Summary, Table of Symbols): Replace %push-parser and %push-pull-parser entries with a %define push_pull entry. * data/bison.m4 (b4_percent_define_check_values): New macro. (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these definitions... * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp definitions... * data/push.c: ... to here and compute them from the value of the %define variable push_pull. * data/c-skel.m4: Instead of choosing the push.c skeleton for push parsing requests here... * data/yacc.c: ... hack this to switch to push.c any time b4_use_push_pull_flag or the %define variable push_pull is set. This will go away when we mv push.c yacc.c. * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that push parsing is not supported since unused %define variables are reported anyway. * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove. * src/muscle_tab.h (muscle_percent_define_check_values): Update comments for consistency with b4_percent_define_check_values. * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag muscles. * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER): Remove. (prologue_declaration): Remove %push-parser and %push-pull-parser rules. * src/scan-gram.l (%push-parser, %push-pull-parser): Remove rules. * tests/calc.at: Update declarations. * tests/input.at (%define enum variables): New test case. * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update declaration. (Push Parsing: Multiple impure instances): Update declaration. (Push Parsing: Unsupported Skeletons): New test case. * tests/torture.at (Exploding the Stack Size with Alloca): Update declaration. (Exploding the Stack Size with Malloc): Update declaration.
