Checklist for GIMPLE assignments
=================================

The assignments  have been  designed with specific  learning objectives.
The following  self-assessment list should give  you a fair idea  of the
extent to which you have learnt the expected material.

Please try to respond to these statements after doing the assignments on
GIMPLE.  Your responses  to the  statements  could be:  `Yes', `No',  or
`Partly', or `I am not sure'.

Please  make sure  that you  move to  an assignment  only after  getting
mostly  `Yes' on  the checklist  for  the previous  assignment. This  is
advisable  even if  this seems  to slow  down your  progress because  in
general, an  assignment assumes the  knowledge gained from  the previous
assignment.

In case  you are  unable to  say `Yes'  for many  of the  statements, we
advise you to  talk to a Teaching Assistant to  clarify the concepts. If
the need be, we  will try to find someone to  explain the concepts later
in the evening.


I know how to add a pass
   a. I know how to instantiate a data structure for adding a pass. (use
      of `struct gimple_opt_pass')
   b. I know how to include the pass as a dynamic plugin by
      i.  specifying   the   positioning   of  the   pass   in   `struct
          register_pass_info'
      ii. activating the plugin in function `plugin_init'


Assignment 1
------------

        1. I know how  to iterate over the edges of  a basic block using
           'FOR_EACH_EDGE'.

        This assignment  does not involve manipulating  the control flow
        graph created by GCC, however, in the rest of the assignments we
        make changes in it.

Assignment 2
------------

        1. I can  identify the types  of GIMPLE statements based  on the
           'gimple_code' of the statement.

        2. I can move the iterator forward using gsi_next() function and
           backward  using  gsi_prev()  function  to get  the  next  and
           previous gimple statements, respectively.

        3. I know how  to split existing basic blocks of  a control flow
           graph.

Assignment 3
------------

        1. I  know how  to  identify assignment  statements  and how  to
           extract operands  on LHS  and RHS  using 'gimple_assign_lhs',
           'gimple_assign_rhs1' and 'gimple_assign_rhs2'.

        2. I know  how to remove gimple  statements using 'gsi_remove()'
           and 'release_defs()'.
