hi
i am trying to add new pass to gimple , my task is to find out how many
Arithmetic operators are there in a given program.
1) i know that i have to create a struct tree_opt_pass i have done that
also,
2) i have added the following line s to tree-pass.h
extern struct tree_opt_pass
3) included next pass in passes.c
4) i have got the function to print the assigiment statements but i have
doubts in that kindly help me
the code is ------------------
void process_statement(tree stmt)
{
tree lval,rval;
switch (TREE_CODE(stmt)){
case GIMPLE_MODIFY_STMT:
lval=GIMPLE_STMT_OPERAND(stmt,0);
rval=GIMPLE_STMT_OPERAND(stmt,1);
if(TREE_CODE(lval) == VAR_DECL) {
if(!DECL_ARTIFICIAL(lval)){
//print_generic_stmt(stderr,stmt,0);
numassigns++;
}
totalassigns++;
}
break;
default :
break;
}
}
Now i want to know what is VAR_DECL and where can i search for that , if I
have to change my code to print Arithmetic statements what other than
VAR_DECL can I use kindly any body know abut gimple optimization help me in
this regard
