We can't append instructions following a return/halt instruction because the control flow helpers will modify the successor of the block containing the return/halt. And the NIR validator enforces that the return/halt must have the end of the function as successor. This tends to happen following lower_shader_calls lowering which inserts halts. This probably doesn't prevent the optimization, it'll just happen in one of the return shaders after the halt has been removed. v2: Move prev block ending check earlier in the function (Daniel) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Cc: mesa-stable Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/12506> |
