X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0680d170d161f2a370e16e2506cb0bf982a8909d;p=mesa.git

nir: Expose nir_print_instr() for debug prints

It's nice to have this present in your default cases so you can see what
instruction is triggering an abort.

v2: Just pass a NULL state, now that it won't crash when you do.
