Hi
I've been trying to add a statement before the statement list before
the basic blocks are created. I am planning to add a function call
statement before a user function is called and I use the instrument
function definition as a statement . The code and the pass compiles
properly but no function is called when the actual program runs.
Can someone hint me where I am going wrong?
static void spmm_init_function(tree *tp)
{
tree func_decl;
tree x,spmm_decl,bind;
tree_stmt_iterator i = tsi_start (*tp);
tree_stmt_iterator last_i;
tree stmt=NULL;
enum tree_code code;
while (!tsi_end_p (i))
{
tree prev_stmt;
prev_stmt = stmt;
stmt = tsi_stmt (i);
code = TREE_CODE (stmt);
switch (code)
{
case CALL_EXPR:
print_
x = implicit_built_in_decls[BUILT_IN_PROFILE_FUNC_ENTER];
x = build_call_expr (x, 0);
tsi_link_after(&i,x,TSI_NEW_STMT);
break;
default:
break;
}
tsi_next(&i);
}
}
