Validation of GIMPLE expressions. Note that these predicates only check * the basic form of the expression, they don't recurse to make sure that * underlying nodes are also of the right form.

Expand EXPR to list of gimple statements STMTS. If SIMPLE is true, force the result to be either ssa_name or an invariant, otherwise just force it to be a rhs expression. If VAR is not NULL, make the base variable of the final destination be VAR if suitable.

Expand EXPR to list of gimple statements STMTS. GIMPLE_TEST_F specifies the predicate that will hold for the result. If VAR is not NULL, make the base variable of the final destination be VAR if suitable.

Invoke force_gimple_operand_1 for EXPR with parameter VAR. If SIMPLE is true, force the result to be either ssa_name or an invariant, otherwise just force it to be a rhs expression. If some statements are produced, emits them at GSI. If BEFORE is true, the statements are appended before GSI, otherwise they are appended after it. M specifies the way GSI moves after insertion (GSI_SAME_STMT or GSI_CONTINUE_LINKING are the usual values).

Some transformations like inlining may invalidate the GIMPLE form for operands. This function traverses all the operands in STMT and gimplifies anything that is not a valid gimple operand. Any new GIMPLE statements are inserted before *GSI_P.
