draw: clean up setting stream out information a bit
In particular noone is interested in the vertex count, so drop that,
and also drop the duplicated num_primitives_generated /
so.primitives_storage_needed variables in drivers. I am unable for now to figure
out if primitives_storage_needed in SO stats (used for d3d10) should
increase if SO is disabled, though the equivalent num_primitives_generated
used for OpenGL definitely should increase. In any case we were only counting
when SO is active both in softpipe and llvmpipe anyway so don't pretend there's
an independent num_primitives_generated counter which would count always.
(This means the PIPE_QUERY_PRIMITIVES_GENERATED count will still be wrong just
as before, should eventually fix this by doing either separate counting for this
query or adjust the code so it always counts this even if SO is inactive depending
on what's correct for d3d10.)

i915: Optimize SEQ and SNE when two operands are uniforms
SEQ and SNE are not native i915 instructions, so they each generate at
least 3 instructions. If both operands are uniforms or constants, we
get 5 instructions like:
U[1] = MOV CONST[1]
U[0].xyz = SGE CONST[0].xxxx, U[1]
U[1] = MOV CONST[1].-x-y-z-w
R[0].xyz = SGE CONST[0].-x-x-x-x, U[1]
R[0].xyz = MUL R[0], U[0]
This code is stupid. Instead of having the individual calls to
i915_emit_arith generate the moves to utemps, do it in the caller. This
results in code like:
U[1] = MOV CONST[1]
U[0].xyz = SGE CONST[0].xxxx, U[1]
R[0].xyz = SGE CONST[0].-x-x-x-x, U[1].-x-y-z-w
R[0].xyz = MUL R[0], U[0]
This allows fs-temp-array-mat2-index-col-wr and
fs-temp-array-mat2-index-row-wr to fit in hardware limits (instead of
falling back to software rasterization).
NOTE: Without pending patches to the piglit tests, these tests will now

For now, nothing else can get allocated over them. That may change at

This also means that base_reg_count can be computed without knowing the

i965: Allow C++ type safety in the use of enum brw_urb_write_flags.
(From a suggestion by Francisco Jerez)
If an enum represents a bitfield of flags, e.g.:
enum E {
A = 1,
B = 2,
C = 4,
D = 8,
};
then C++ normally prohibits statements like this:
enum E x = A | B;
because A and B are implicitly converted to ints before OR-ing them,
and an int can't be stored in an enum without a type cast. C, on the
other hand, allows an int to be implicitly converted to an enum
without casting.
In the past we've dealt with this situation by storing flag bitfields
as ints. This avoids ugly casting at the expense of some type safety
that C++ would normally have offered (e.g. we get no warning if we
accidentally use the wrong enum type).
However, we can get the best of both worlds if we override the |
operator. The ugly casting is confined to the operator overload, and
we still get the benefit of C++ making sure we don't use the wrong
enum type.
v2: Remove unnecessary comment and unnecessary use of "enum" keyword.
Use static_cast.

freedreno/a3xx/compiler: make compiler errors more useful
We probably should get rid of assert() entirely, but at this stage it is
more useful for things to crash where we can catch it in a debugger.
With compile_error() we have a single place to set an error flag (to
bail out and return an error on the next instruction) so that will be a
small change later when enough of the compiler bugs are sorted.
But re-arrange/cleanup the error/assert stuff so we at least get a dump
of the TGSI that triggered it. So we see some useful output in piglit
logs.

freedreno/a3xx/compiler: cat4 cannot use const reg as src
Category 4 instructions (rsq, rcp, sqrt, etc) seem to be unable to take
a const register as src. In these cases we need to move the src to a
temporary gpr first.
This is the second case of such a restriction, where the instruction
encoding appears to support a const src, but in fact the hw appears to
ignore that bit. So split things out into a helper that can be re-used
for any instructions which have this limitation.

file_count[file] != file_max[file] + 1.

gallivm: fix min/mag switchover point for nearest/none mip filter
Previously, the min/mag switchover point when using nearest/none mip
filter was effectively -0.5 which can't be right. Looks like new OpenGL
thinks it's ok if it's always 0.0 (older versions required 0.5 in some
cases), let's hope everybody else thinks that's fine too.
Refactor this slightly and get the per-quad/per-pixel min/mag decision
values further down to sampling, though still only the first component
is used yet.
While here also fix code trying to skip lod bias application etc. when
mipfilter is none, as this is still needed for determining min/mag filter.
