Now that backend_reg inherits from brw_reg, we have to be careful to
avoid the object slicing problem.
Reviewed-by: Francisco Jerez <currojerez@riseup.net>
In the next patch, I make backend_reg's inheritance from brw_reg
private, which confuses clang when it sees the type "struct brw_reg" in
the derived class constructors, thinking it is referring to the
privately inherited brw_reg:
brw_fs.cpp:366:23: error: 'brw_reg' is a private member of 'brw_reg'
fs_reg::fs_reg(struct brw_reg reg) :
^
brw_shader.h:39:22: note: constrained by private inheritance here
struct backend_reg : private brw_reg
^~~~~~~~~~~~~~~
brw_reg.h:232:8: note: member is declared here
struct brw_reg {
^
Avoid this by marking brw_reg with the scope resolution operator.
In order to do this, we have to change the signature of the
backend_reg(brw_reg) constructor to take a reference to a brw_reg in
order to avoid unresolvable ambiguity about which constructor is
actually being called in the other modifications in this patch.
As far as I understand it, the rule in C++ is that if multiple
constructors are available for parent classes, the one closest to you in
the class heirarchy is closen, but if one of them didn't take a
reference, that screws things up.

gallium. They don't have any helpers hooked up for software decoding, however,
so cannot support them in drivers relying on util code for decoding.

Removing the fake format helpers (1c7d0a6aa4)
caused this to fail. These formats were never supported, but previously
they would have asserted in the generated jit functions (which, due to lack
of test cases for these formats, were never called) whereas we now assert when
trying to build the jit function. So, skip them completely.

This reverts commit ba02f7a3b6.
The commit checked whether the pipeline was currently bound instead
of checking whether it had ever been bound. The previous setting
of Validated during object creation makes this unnecessary. The
real problem was that Validated was not properly set to false
elsewhere in the code. This is fixed by a later patch.

Now that nir_lower_tex can do texture swizzle lowering, we can use that
instead of repeating more-or-less the same code in both backends. This
both allows us to share code and means that things like the tg4
work-arounds are somewhat simpler because they don't have to take the
swizzle into account.

nir_ssa_def_rewrite_uses is one of the older helpers in NIR and predated

Previously, if someone accidentally made an instruction that refers to its
own SSA destination, the validator wouldn't catch it. The reason for this
is that it validated the destination too early and, by the time it got to
the source, the destination SSA value was already added to the set of seen
SSA values so it would assume that it came from some previous instruction.
By moving destination validation to be after source validation, the SSA
value is not in the list of seen values and the validator will catch
self-referential instructions.

Previously, we had a rescale_texcoords helper in the FS backend for
handling rescaling of texture coordinates. Now that we can do variants in
NIR, we can use nir_lower_tex to do the rescaling for us. This allows us
to delete the i965-specific code and gives us proper TEXTURE_RECTANGLE and
GL_CLAMP handling in vertex and geometry shaders.

This allows us to insert NIR passes between initial NIR compilation and
optimization (link time) and actual backend code-gen. In particular, it
will allow us to do shader variants in NIR and share some of that shader
variant code between backends.

At the moment, brw_create_nir just calls the three stages in sequence so
there's not much difference. Soon, however, we will want to start doing
variants in NIR at which point the postprocessing step will have to move
from shader create time to codegen time.
