[Mesa-dev] Question for nir lower load uniform to scalar

[Qiang Yu]

Hi Eric,

I'm working on lima gp compiler which should benefit from nir lowering
uniform load to scalar.
I notice you write the nir_lower_io_to_scalar.c which support lowering
shader_in/shader_out
but left the uniform lowering in vc4 driver, any reason why not
implement in the nir_lower_io_to_scalar.c?

I'm new to nir, tried to add it but seems not correct after
optimization pass. So I should missing
some place, anyone can help to point out?

Thanks,
Qiang
