When the width field was removed from fs_reg the BROADCAST handling code in opt_algebraic() started to miss a number of trivial optimization cases resulting in the ugly indirect-addressing sequence to be emitted unnecessarily for some variable-indexed texturing and UBO loads regardless of one of the sources of BROADCAST being immediate. Apparently the reason was that we were setting the stride field to one for immediates even though they are typically uniform. Width used to be set to one too which is why this optimization used to work previously until the "reg.width == 1" check was removed. The stride field of vector immediates is intentionally left equal to one, because they are strictly speaking not uniform. The assertion in fs_generator makes sure that immediates have the expected stride as consistency check. Reviewed-by: Samuel Iglesias Gonsálvez <siglesias@igalia.com> |
