238 * `nocache` - you always want to use this when debugging, otherwise you risk using a broken shader …
239 * `shaders` - makes ACO print the IR after register allocation, as well as the disassembled shader …
240 * `metashaders` - does the same thing as `shaders` but for built-in RADV shaders.
241 * `preoptir` - makes ACO print the final NIR shader before instruction selection, as well as the AC…
242 * `nongg` - disables NGG support
246 * `validateir` - Validate the ACO IR between compilation stages. By default, enabled in debug build…
247 * `validatera` - Perform a RA (register allocation) validation.
248 * `perfwarn` - Warn when sub-optimal instructions are found.
249 * `force-waitcnt` - Forces ACO to emit a wait state after each instruction when there is something …
250 * `novn` - Disables the ACO value numbering stage.
251 * `noopt` - Disables the ACO optimizer.
252 * `nosched` - Disables the ACO scheduler.
