14 * Enters all transform functions into the generic pointer

19 * Transforms the given Firm node into one or more appropriate ia32 nodes.
21 void ia32_transform_node(ir_node *node, void *env);
24 * Transforms a Sub or fSub into Neg--Add iff OUT_REG == SRC2_REG.
25 * THIS FUNCTIONS MUST BE CALLED AFTER REGISTER ALLOCATION.
27 void ia32_transform_sub_to_neg_add(ir_node *irn, ia32_code_gen_t *cg);
30 * Transforms a LEA into an Add if possible
31 * THIS FUNCTIONS MUST BE CALLED AFTER REGISTER ALLOCATION.
33 void ia32_transform_lea_to_add(ir_node *irn, ia32_code_gen_t *cg);
36 * The Psi selector can be a tree of compares combined with "And"s and "Or"s.
37 * We create a Set node, respectively a xCmp in case the Psi is a float, for each
38 * compare, which causes the compare result to be stores in a register. The
39 * "And"s and "Or"s are transformed later, we only adjust their mode.
41 void ia32_transform_psi_cond_tree(ir_node *node, void *env);
45 * Prints the old node name on cg obst and returns a pointer to it.
