Hi, This patch cleans up some code and adds some comments about why the code looks like it is and removes one outdated comment which is no longer true. Committed to the branch after a bootstrap/test on i686-linux-gnu. Thanks, Andrew Pinski ChangeLog: * fold-const.c (try_move_mult_to_index): Say why we strip the nops. (fold_unary <case NOP_EXPR>): Remove TODO as we cannot get that case. * tree-chrec.c (chrec_fold_plus): Cleanup the code to chose which tree code is used. (chrec_convert_rhs): Add comment on why the increment is sizetype for pointers. * tree-mudflap.c (mf_xform_derefs_1): Use size_int instead of build_int_cst. * tree-ssa-loop-prefetch.c (issue_prefetch_ref): Likewise. cp/ChangeLog: * typeck.c (build_binary_op): Add a comment on why creating the tree in pieces while processing templates.
