Kenneth Graunke [Tue, 8 Dec 2015 04:18:42 +0000 (20:18 -0800)]
i965: Handle mix-and-match TCS/TES with separate shader objects.

GL_ARB_separate_shader_objects allows the application to mix-and-match
TCS and TES programs separately.  This means that the interface between
the two stages isn't known until the final SSO pipeline is in place.

This isn't a great match for our hardware: the TCS and TES have to agree
on the Patch URB entry layout.  Since we store data as per-patch slots
followed by per-vertex slots, changing the number of per-patch slots can
significantly alter the layout.  This can easily happen with SSO.

To handle this, we store the [Patch]OutputsWritten and [Patch]InputsRead
bitfields in the TCS/TES program keys, introducing program recompiles.
brw_upload_programs() decides the layout for both TCS and TES, and
passes it to brw_upload_tcs/tes(), which store it in the key.

When creating the NIR for a shader specialization, we override
nir->info.inputs_read (and friends) to the program key's values.
Since everything uses those, no further compiler changes are needed.
This also replaces the hack in brw_create_nir().

To avoid recompiles, brw_precompile_tes() looks to see if there's a
TCS in the linked shader.  If so, it accounts for the TCS outputs,
just as brw_upload_programs() would.  This eliminates all recompiles
in the non-SSO case.  In the SSO case, there should only be recompiles
when using a TCS and TES that have different input/output interfaces.

Fixes Piglit's mix-and-match-tcs-tes test.

With tessellation shaders and SSO, we won't be able to always decide on
VUE map layouts at LinkProgram time.  Unfortunately, we have to delay it
until shader specialization time.

However, uniform lowering cannot be deferred - brw_codegen_*_prog()
reads nir->num_uniforms.  Fortunately, we don't need to defer it -
uniform, system value, atomic, and sampler lowering can safely stay
where it is.  This patch moves those to brw_lower_nir()'s only caller,
renames brw_lower_nir() to brw_nir_lower_io(), and introduces calls
to that.

For non-tessellation stages, I chose to call brw_nir_lower_io() from
