Design notes:
|
||||||
|
Do not use a manually maintained stack like thd->lex->xxx_list,
|
||||||
|
but use the internal bison stack ($$, $1 and $3) instead.
|
||||||
|
Using the bison stack is:
|
||||||
|
- more robust to changes in the grammar,
|
||||||
|
- guaranteed to be in sync with the parser state,
|
||||||
|
- better for performances (no memory allocation).
