with vtn_bindgen2 we only care about a single function at a time, not a whole
nir_shader, and it would be quite wasteful to serialize all the shader info
every time. add a specialized serialize just for 1 function.

It's not at all clear how this pass should work with real function calls (if at
all), but at least this is enough to handle collections of self-contained
functions which vtn_bindgen2 wants.

When the core supports unified instruction memory, don't clamp individual
shader sizes to 256 instructions. Allow shaders to make full use of the
state instruction memory, as long as both VS and FS fit into the memory
region.
Allows to run the shaders from glmark2 terrain from state instruction
memory, so we don't need to use icache mode on GC3000 and makes the app
work on GC2000, which doesn't have icache but unified instruction memory.

Currently we statically partition the unified intsruction memory range
into a VS and a FS range, with each of the shader types getting half
of the memory. Change this to place the FS instructions right behind
the VS instructions, which potentially allows larger shaders to be
executed from the instruction memory states when VS are FS are
unbalanced in size, which is quite common.

There is no reason to emit those states on framebuffer changes. While the
framebuffer format change might change the fragment shader due to R/B
swapping in the shader, this triggers compilation of a new shader variant

Annotating ssa defs without affecting compilation is impossible with
debug info instructions since referencing a nir_def from the debug info
instr will add uses.
The old approach also stops worrking if passes reorder instructions.
This patch proposes a solution which should not regress performance just
like the old approach. The difference is that this one allocates a bit
more space for debug info instead of adding a new instruction for it.

device creation and image creation, respectively. This means that if
the options are enabled after the device/image is created, LRZ
will still be used. Similarly, if the options are disabled after the

This change moves the checks to the point where the LRZ is actually
