These are all new false positives with gcc6. In nouveau_compiler.c: gcc6 no longer assumes that passing a pointer to a variable into a function initialises that variable.
In nv50_ir_from_tgsi.cpp op and mode are not set if there are 0 enabled dst channels, this never happens, but gcc cannot know this.
