Specify the set of benches to run. The following grammar defines the
I<directives>:
- I<directives> ::= I<directives> | I<directives> -- Alternation
- | I<directives> & I<directives> -- Concatenation
- | [ I<directives> ] -- Optional
- | ( I<directives> ) -- Parentheses
- | I<directive>
+ directives ::=
+ directives | directives -- Alternation
+ | directives & directives -- Concatenation
+ | [ directives> ] -- Optional
+ | ( directives> ) -- Parentheses
+ | %s skeleton -- %skeleton "skeleton"
+ | #d definition -- %code { #define definition }
+ | directive
Parentheses only group to override precedence. For instance:
sub bench_variant_parser ()
{
bench ('list',
- ('%skeleton "lalr1.cc"',
- '&',
- '[', '%debug', ']',
- '&',
- '[', '%define variant',
- '&',
- '[', "%code {\n#define VARIANT_DESTROY\n}", ']',
- '&',
- '[', "%code {\n#define ONE_STAGE_BUILD\n}", ']',
- ']'
- ));
+ qw(
+ %s lalr1.cc
+ &
+ [ %debug ]
+ &
+ [ %define variant
+ &
+ [ #d VARIANT_DESTROY ]
+ &
+ [ #d ONE_STAGE_BUILD ]
+ ]
+ )
+ );
