4.4 API changes

4.4 API changes

[Jamie Prescott]

I managed to migrate my code to 4.4, but I've some code I cannot figure out
how to translate.
Before, I was building the TRUE and FALSE  instruction list using gimplify_and_add(),
and then a:

build3(COND_EXPR, void_type_node, cond, a_case, b_case);

Where 'a_case' and 'b_case' were tree's.
Now I build two gimple_seq's in the same way, but I cannot see how to pass them to build3().
Is there an API to get the first tree out of the gimple_seq? Or, is there a build3() equivalent
that accepts gimple_seq's?

Are you trying to generate gimple or generic?  Both are different data
structures now.

This is the varargs code, and I currently solved it by using append_to_statement_list(),
and then adding the resulting tree to the pre_p and post_p using gimplify_and_add().
Is it OK?

Take a look at mainstream ports (x86, rs6000, etc) and use them as a model.
