From 6560838703431f89c47d68822758bc76fd34c355 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 1 Sep 2015 22:56:29 -0700 Subject: [PATCH] nir/cf: Fix unlink_block_successors to actually unlink the second one. Calling unlink_blocks(block, block->successors[0]) will successfully unlink the first successor, but then will shift block->successors[1] down to block->successor[0]. So the successors[1] != NULL check will always fail.
