We use this logic to detect live ranges and then do plain renaming
across the whole codebase. As such, to prevent WaW hazards, we have to
treat a write as if it were also a read.
For example, the following sequence was observed before this patch:
13: UIF TEMP[6].xxxx :0
14: ADD TEMP[6].x, CONST[6].xxxx, -IN[3].yyyy
15: RCP TEMP[7].x, TEMP[3].xxxx
16: MUL TEMP[3].x, TEMP[6].xxxx, TEMP[7].xxxx
17: ADD TEMP[6].x, CONST[7].xxxx, -IN[3].yyyy
18: RCP TEMP[7].x, TEMP[3].xxxx
19: MUL TEMP[4].x, TEMP[6].xxxx, TEMP[7].xxxx
While after this patch it becomes:
13: UIF TEMP[7].xxxx :0
14: ADD TEMP[7].x, CONST[6].xxxx, -IN[3].yyyy
15: RCP TEMP[8].x, TEMP[3].xxxx
16: MUL TEMP[4].x, TEMP[7].xxxx, TEMP[8].xxxx
17: ADD TEMP[7].x, CONST[7].xxxx, -IN[3].yyyy
18: RCP TEMP[8].x, TEMP[3].xxxx
19: MUL TEMP[5].x, TEMP[7].xxxx, TEMP[8].xxxx
Most importantly note that in the first example, the second RCP is done
on the result of the MUL while in the second, the second RCP should have
the same value as the first. Looking at the GLSL source, it is apparent
that both of the RCP's should have had the same source.
Looking at what's going on, the GLSL looks something like
float tmin_8;
float tmin_10;
tmin_10 = tmin_8;
... lots of code ...
tmin_8 = tmpvar_17;
... more code that never looks at tmin_8 ...
And so we end up with a last_read somewhere at the beginning, and a
first_write somewhere at the bottom. For some reason DCE doesn't remove
it, but even if that were fixed, DCE doesn't handle 100% of cases, esp
including loops.
With the last_read somewhere high up, we overwrite the previously
correct (and large) last_read with a low one, and then proceed to decide
to merge all kinds of junk onto this temp. Even if that weren't the
case, and there were just some writes after the last read, then we might
still overwrite a merged value with one of those.
As a result, we should treat a write as a last_read for the purpose of
determining the live range.

If an instruction has multiple defs, we have to do a lot more checks to
make sure that we can move it forward. Among other things, various code
likes to do
a, b = tex()
if () c = a
else c = b
which means that a single phi node will have results pointing at the
same instruction. We obviously can't propagate the tex in this case, but
properly accounting for this situation is tricky. Just don't try for
instructions with multiple defs.
This fixes about 20 shaders in shader-db, including the dolphin efb2ram

It appears that the nvidia render engine is quite picky when it comes to
linear surfaces. It doesn't like non-256-byte aligned offsets, and
apparently doesn't even do non-256-byte strides.
This makes arb_clear_buffer_object-unaligned pass on both nv50 and nvc0.
As a side-effect this also allows RGB32 clears to work via GPU data
upload instead of synchronizing the buffer to the CPU (nvc0 only).

Currently any access params (coherent/volatile/restrict) are being lost
when lowering to the ssbo load/store intrinsics. Keep track of the
variable being used, and bake its access params in as the last arg of
the load/store intrinsics.
If the variable is accessed via an instance block, then 'variable'
points to the instance block variable and not the field inside the
instance block that we are accessing. In order to check access
parameters for the field itself we need to detect this case and keep
track of the corresponding field struct so we can extract the specific
field access information from there instead.
