Sorry, my initial answer was not quite correct.
The way to do this in Bison is to access the semantic value of the
previous non-terminal in the parent rule as $0. For example:
A: B C D
C: X { $0 is the semantic value of B}
This is risky. One has to take care that in all places where a
non-term
You have to put the register_name as an attribute of Register_decl_control
%union {
struct register_decl_contd_data {
const char* register_name;
/* other data that you want for register_decl_contd */
} register_decl_contd_data;
// Other union members for other terminals and non
I am interested in developing a LR(1) optimized parser generator
similar to the one implemented in Menhir. I have seen discussion about
it in the mailing lists, but I cannot find any code in the CVS tree.
What is the current status of implementation?
I am also interested in implementing Burke-Fish
The deadline for submission of projects for Google summer of code
grants has passed. Never theless, I might be insterested in
implementing Burke-Fisher error correction, within time limits.

I think that state compacting is not incompatible with good error
handling. Did you read the paper of Burke-Fisher error correction? It
is not incompatible with state merging, though more information must
be stored in the stack.

As for the "Burke-Fisher Error Correction", error recovery is poor in
Bison because the LALR(1) algorithm may, when an error token appears
in the input, performed some reductions before the error is reported.
Perhaps I am wrong, but I think that these wrong reductions also
exists when using effi
Hello,
I am interested in implementing LR(1) grammar support, which was
proposed for the 2006 edition of Google Summer of Code. Is it posible
to request this project for this year?
Thanks,
