Dear all,
I must calculate the address of an element's array.
If the size of an element is one integer it's good.
I do like that:
new_rhs=fold_build2(PLUS_EXPR,TREE_TYPE(TREE_OPERAND(rhs,1)),
build1(ADDR_EXPR, build_pointer_type (TREE_TYPE
(array)),array),
index);
But, if the type of an element is not one integer, I must multiply the
index by the size of an element.
I try to do like that :
tree decalage=fold_build2(MULT_EXPR,TREE_TYPE(index),
index,
compteur);
new_rhs=fold_build2(PLUS_EXPR,TREE_TYPE(TREE_OPERAND(rhs,1)),
build1(ADDR_EXPR,
build_pointer_type (TREE_TYPE (array)),array),
decalage);
new_rhs is a futur parameter of a function call.
When a try to compile a program gcc answer:
"
tab.c:22: erreur: invalid operand to binary operator
i_28 * 4;
tab.c:22: erreur interne du compilateur: verify_stmts failed
"
i_28 is index
4 is compteur
How can I do that ?
Thanks in advance.
