From b1802a2115323233352da558430e109ff187b8af Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sun, 1 Jul 2012 16:21:32 -0700 Subject: [PATCH] glsl: Remove unused ir_loop_jump::loop pointer. Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also accidentally added a new pointer to the enclosing loop. Furthermore, it tried to initialize the new field by adding "this->loop = loop;" to the constructor, but since there is no loop parameter, this only initialized the field to itself---so it will likely be a garbage pointer. A lot of code, such as lower_jumps, allocates new loop jumps without setting this field appropriately, so any uses would probably just crash. Thankfully, there were none, so we can just delete the field.
