From e16531fbe3a79bc27cf00701616a260b452597ef Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 31 Aug 2015 16:54:02 -0700 Subject: nir/builder: Use nir_after_instr to advance the cursor This *should* ensure that the cursor gets properly advanced in all cases. We had a problem before where, if the cursor was created using nir_after_cf_node on a non-block cf_node, that would call nir_before_block on the block following the cf node. Instructions would then get inserted in backwards order at the top of the block which is not at all what you would expect from nir_after_cf_node. By just resetting to after_instr, we avoid all these problems.
