Even if the ast-optimizer is broken,
here is the bug report
Bison version : unstable 1.75-1, this is the problem
but it i working with the stable 1.35-3.
The file in question is
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/gengtype-yacc.y
The error output got lost, I will retry it with the main branch was
about this construction
typedef_struct: ENT_TYPEDEF_STRUCT options '{' struct_fields '}' ID
{
new_structure ($1->u.s.tag, UNION_P ($1), &lexer_line,
$4, $2);
do_typedef ($6, $1, &lexer_line);
lexer_toplevel_done = 1;
}
';'
{}
| ENT_STRUCT options '{' struct_fields '}'
{
new_structure ($1->u.s.tag, UNION_P ($1), &lexer_line,
$4, $2);
lexer_toplevel_done = 1;
}
';'
{}
;
there was some conflict between the two.
I am just compiling the new bison locally to avoid de-installing 1.35,
and will report the exact bug tonight (Timezone: GMT +1 )
I will also be looking into doing the switch over to the tree simplied
version. it looks interesting.
