Dear helpers,
I want to calculate the size of all variables in a function. I try with the following code but it doesn't run. Please help me. Thank you very much.
int size_of_vars (fndecl) //fndecl is FUNCTION_DECL
tree fndecl;
{
tree t;
HOST_WIDE_INT total_size = 0;
tree let = DECL_INITIAL (fndecl);
for (t = BLOCK_VARS (let); t; t = TREE_CHAIN (t))
total_size += int_size_in_bytes (TREE_TYPE (t));
/* Process all subblocks. */
for (t = BLOCK_SUBBLOCKS (let); t; t = TREE_CHAIN (t))
total_size += size_of_vars (t);
}
return total_size;
}
Regard,
