This patch reduces the likelihood of pointer arithmetic overflow bugs in
gather_oa_results(), like the one fixed by b69c7c5dac.
I haven't yet encountered any overflow bugs in the wild along this
patch's codepath. But I get nervous when I see code patterns like this:
(void*) + (int) * (int)
I smell 32-bit overflow all over this code.
This patch retypes 'snapshot_size' to 'ptrdiff_t', which should fix any
potential overflow.

This patch reduces the likelihood of pointer arithmetic overflow bugs in
intel_texsubimage_tiled_memcpy() , like the one fixed by b69c7c5dac.
I haven't yet encountered any overflow bugs in the wild along this
patch's codepath. But I recently solved, in commit b69c7c5dac, an overflow
bug in a line of code that looks very similar to pointer arithmetic in
this function.
This patch conceptually applies the same fix as in b69c7c5dac. Instead
of retyping the variables, though, this patch adds some casts. (I tried
to retype the variables as ptrdiff_t, but it quickly got very messy. The
casts are cleaner).

(cherry picked from commit 225a09790d)
This is a partial revert of c89306983c.
It split the {start,base}_vertex_location handling into several steps:
1. Set brw->draw.start_vertex_location = prim[i].start
and brw->draw.base_vertex_location = prim[i].basevertex.
(This happened once per _mesa_prim, in the main drawing loop.)
2. Add brw->vb.start_vertex_bias and brw->ib.start_vertex_offset
appropriately. (This happened in brw_prepare_shader_draw_parameters,
which was called just after brw_prepare_vertices, as part of state
upload, and only happened when BRW_NEW_VERTICES was flagged.)
3. Use those values when emitting 3DPRIMITIVE (once per _mesa_prim).
If we drew multiple _mesa_prims, but didn't flag BRW_NEW_VERTICES on
the second (or later) primitives, we would do step #1, but not #2.
The first _mesa_prim would get correct values, but subsequent ones
would only get the first half of the summation.
The reason I originally did this was because I needed the value of
gl_BaseVertexARB to exist in a buffer object prior to uploading
3DSTATE_VERTEX_BUFFERS. I believed I wanted to upload the value
of 3DPRIMITIVE's "Base Vertex Location" field, which was computed
as: (prims[i].indexed ? prims[i].start : prims[i].basevertex) +
brw->vb.start_vertex_bias. The latter value wasn't available until
after brw_prepare_vertices, and the former weren't available in the
state upload code at all. Hence the awkward split.
However, I believe that including brw->vb.start_vertex_bias was a
mistake. It's an extra bias we apply when uploading vertex data into
VBOs, to move [min_index, max_index] to [0, max_index - min_index].
>From the GL_ARB_shader_draw_parameters specification:
"<gl_BaseVertexARB> holds the integer value passed to the <baseVertex>
parameter to the command that resulted in the current shader
invocation. In the case where the command has no <baseVertex>
parameter, the value of <gl_BaseVertexARB> is zero."
I conclude that gl_BaseVertexARB should only include the baseVertex
parameter from glDraw*Elements*, not any internal biases we add for
optimization purposes.
With that in mind, gl_BaseVertexARB only needs prim[i].start or
prim[i].basevertex. We can simply store that, and go back to computing
start_vertex_location and base_vertex_location in brw_emit_prim(), like
we used to. This is much simpler, and should actually fix two bugs.

glXSwapBuffersMscOML() with target_msc=divisor=remainder=0 gets
translated into target_msc=divisor=0 but remainder=1 by the mesa
api. This is done for server DRI2 where there needs to be a way
to tell the server-side DRI2ScheduleSwap implementation if a call
to glXSwapBuffers() or glXSwapBuffersMscOML(dpy,window,0,0,0) was
done. remainder = 1 was (ab)used as a flag to tell the server to
select proper semantic. The DRI3/Present backend ignored this
signalling, treated any target_msc=0 as glXSwapBuffers() request,
and called xcb_present_pixmap with invalid divisor=0, remainder=1
combo. The present extension responded kindly to this with a
BadValue error and dropped the request, but mesa's DRI3/Present
backend doesn't check for error codes. From there on stuff went
downhill quickly for the calling OpenGL client...

Prevent calls to glXGetSyncValuesOML() and glXWaitForMscOML()
from overwriting the (ust,msc) values of the last successfull
swapbuffers call (PresentPixmapCompleteNotify event), as
glXWaitForSbcOML() relies on those values corresponding to
the most recent completed swap, not to whatever was last
returned from the server.
Problematic call sequence without this patch would have been, e.g.,
glXSwapBuffers()
... wait ...
swap completes -> PresentPixmapComplete event -> (ust,msc)
updated to reflect swap completion time and count.
... wait for at least 1 video refresh cycle/vblank increment.
glXGetSyncValuesOML()
-> PresentNotifyMsc event overwrites (ust,msc) of swap
completion with (ust,msc) of most recent vblank
glXWaitForSbcOML()
-> Returns sbc of last completed swap but (ust,msc) of last
completed vblank, not of last completed swap.
-> Client is confused.
Do this by tracking a separate set of (ust, msc) for the
dri3_wait_for_msc() call than for the dri3_wait_for_sbc()
call.
This makes the glXWaitForSbcOML() call robust again and restores
consistent behaviour with the DRI2 implementation.
Fixes applications originally written and tested against
DRI2 which also rely on this not regressing under DRI3/Present,
e.g., Neuro-Science software like Psychtoolbox-3.

So when checking/building sse code we have three possibilities:

3 New compiler, user doesn't disable sse
The original code, added code for #1 but not #2. Later on we patched
around the lack of handling #2 by wrapping the code in __SSE4_1__.
Yet it lead to a missing/undefined symbol in case of #1 or #2, which
might cause an issue for #2 when using the i965 driver.
A bit later we "fixed" the undefined symbol by using #1, rather than
updating it to handle #2. With this commit we set things straight :)
To top it all up, conventions state that in case of conflicting

4f338c9b introduced logic to trigger a flush rather than overflowing
cmdstream buffer. But the threshold was too low, triggering flushes
where they were not needed. This caused problems with games like
xonotic.
Part of the problem is that we need to mark all state dirty between
cmdstream submit ioctls, because we cannot rely on state being
preserved across ioctls. But even with that, there are still some
problems that are still being debugged. For now:
1) correctly mark all state dirty
2) introduce FD_MESA_DEBUG flush flag to force rendering to be flushed
between each draw, to trigger problems (so that I can debug)
3) use a more reasonable threshold so for normal usecases we don't
trigger the problems
This at least corrects the regression, but there is still more debugging
to do.

We currently aren't too clever about dealing with running out of

of the cmdstream buffer to fit the tiling commands.
Until we get more clever, the easy solution is a threshold to trigger
flushing rendering even if the application does not trigger flush (swap,
changing render target, etc). This way we at least don't crash for apps
that do several thousand draw calls (like some piglit tests do).

There are some cases where the scheduler can get itself into impossible
situations, by scheduling the wrong write to pred or addr register
first. (Ie. it could end up being unable to schedule any instruction if
some instruction which depends on the current addr/reg value also
depends on another addr/reg value.)
To solve this we'd need to be able to insert extra mov instructions
(which would also help when register assignment gets into impossible
situations). To do that, we'd need to move the nop padding from sched
into legalize.
But to start with, just detect when we get into an impossible situation
and bail, rather than sitting forever in an infinite loop. This way it
will at least fall back to the old compiler, which might even work if
you are lucky.

(cherry picked from commit 94841b6d5d)
Write-back caching cannot be used for buffers being scanned out by the
display engine; surfaces used for scan-out must be write-through or
uncached. I originally chose WT for render targets because it works in
all cases. However, we really want to use write-back caching where
possible, as it is more efficient.
Most renderbuffers are not used for scanout - off-screen FBOs certainly
are fine, and non-pageflipped backbuffers should be fine as well. So
in most cases WB will work. However, we don't know what will be used
for scan-out, so we instead simply use the PTE value specified by the
kernel, as it knows these things.
This matches our MOCS choice on Haswell.

In commit 567e2769b8 ("ra: make the p, q

register allocator API: the user must set the register class of all
nodes before setting up their interferences, because
ra_add_conflict_list() now uses the classes of the two interfering
nodes. i965 already did this, but r300g was setting up register classes
interleaved with setting up the interference graph. This led to us
calculating the wrong q total, and in certain cases
e78a01d5e6 (" ra: optimistically color
only one node at a time") made it so that this bug caused a segfault. In
particular, the error occurred if the q total was decremented to 1 below
0 for the last node to be pushed onto the stack. Since q_total is an
unsigned integer, it overflowed to 0xffffffff, which is what
lowest_q_total happens to be initialzed to. This means that we would
fail the "new_q_total < lowest_q_total" check on line 476 of
register_allocate.c, and so the node would never be pushed onto the
stack, which led to segfaults in ra_select() when we failed to ever give
it a register.

(cherry picked from commit 7aeb853c90)
So far we have been using CL_INVOCATION_COUNT to resolve this query but this
is no good with streams, as only stream 0 reaches the clipping stage.
From ARB_transform_feedback3:
"When a generated primitive query for a vertex stream is active, the
primitives-generated count is incremented every time a primitive emitted to
that stream reaches the Discarding Rasterization stage (see Section 3.x)
right before rasterization. This counter is incremented whether or not
transform feedback is active."
Unfortunately, we don't have any registers that provide the number of primitives
written to a specific stream other than the ones that track the number of
primitives written to transform feedback in the SOL stage, so we can't
implement this exactly as specified.
In the past we implemented this feature by activating the SOL unit even if
transform feeback was disabled, but making it so that all buffers were
disabled and it only recorded statistics, which gave us the right semantics
(see 3178d2474a). Unfortunately, this came with
a significant performance impact and had to be reverted.
This new take does not intend to implement the exact semantics required by
the spec, but improves what we have now, since now we return the primitive
count for stream 0 in all cases. With this patch we use
GEN7_SO_PRIM_STORAGE_NEEDED to resolve GL_PRIMITIVES_GENERATED queries
for non-zero streams. This would return the number of primitives written
to transform feedback for each stream instead. Since non-zero streams are
only useful in combination with transform feedback this should not be too
bad, and the only case that I think we would not be supporting would be
the one in which we want to use both GL_PRIMITIVES_GENERATED and
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN on the same non-zero stream to
detect buffer overflow.
This patch also fixes the following piglit test:
arb_gpu_shader5-xfb-streams-without-invocations
This test uses both GL_PRIMITIVES_GENERATED and
GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN queries on non-zero streams, but it
does never hit the overflow case, so both queries are always expected to return
the same value.

Nominated-by: Kenneth Graunke <kenneth@whitecape.org>
ir_rvalue::constant_expression_value() recursively walks down an IR
tree, attempting to reduce it to a single constant value. This is
useful when you want to know whether a variable has a constant
expression value at all, and if so, what it is.
The constant folding optimization pass attempts to replace rvalues with
their constant expression value from the bottom up. That way, we can
optimize subexpressions, and ideally stop as soon as we find a
non-constant subexpression.
In order to obtain the actual value of an expression, the optimization
pass calls constant_expression_value(). But it should only do so if it
knows the value can be combined into a constant. Otherwise, at each
step of walking back up the tree, it will walk down the tree again, only
to discover what it already knew: it isn't constant.
We properly avoided this call for ir_expression nodes, but not for
ir_swizzle nodes. This patch fixes that, drastically reducing compile
times on certain shaders where tree grafting has given us huge
expression trees. It also fixes SuperTuxKart.
Thanks to Iago and Mike for help in tracking this down.

Samplers take up zero slots and therefore don't exist in the params
array, nor are they included in stage_prog_data->nr_params. There's no
need to store their size in param_size, as it's only used for dealing
with arrays of "real" uniforms (ones uploaded as shader constants).
We run into all kinds of problems trying to refer to the uniform storage
for variables that don't have uniform storage. For one, we may use some
other variable's index, or access out of bounds in arrays. In the FS
backend, our extra 2 * MaxSamplerImageUnits params for texture rectangle
rescaling paper over a lot of problems. In the VS backend, we claim
samplers take up a slot, which also papers over problems.
Instead, just skip allocating storage for variables that don't have any.

(cherry picked from commit 2408f166db)
Apparently guardband clipping doesn't work like we thought: objects
entirely outside fthe guardband are trivially rejected, regardless of
their relation to the viewport. Normally, the guardband is larger than
the viewport, so this is not a problem. However, when the viewport is
larger than the guardband, this means that we would discard primitives
which were wholly outside of the guardband, but still visible.
We always program the guardband to 8K x 8K to enforce the restriction
that the screenspace bounding box of a single triangle must be no more
than 8K x 8K. So, if the viewport is larger than that, we need to
disable guardband clipping.

We always uploaded them together, mostly out of laziness - both required
an additional vertex element. However, gl_VertexID now also requires an
additional vertex buffer for storing gl_BaseVertex; for non-indirect
draws this also means uploading (a small amount of) data. This is extra
overhead we don't need if the shader only uses gl_InstanceID.
In particular, our clear shaders currently use gl_InstanceID for doing
layered clears, but don't need gl_VertexID.

In the non-indirect draw case, we call intel_upload_data to upload
gl_BaseVertex. It makes brw->draw.draw_params_bo point to the upload
buffer, and increments the upload BO reference count.
So, we need to unreference it when making brw->draw.draw_params_bo point
at something else, or else we'll retain a reference to stale upload
buffers and hold on to them forever.
This also means that the indirect case should increment the reference
count on the indirect draw buffer when making brw->draw.draw_params_bo
point at it. That way, both paths increment the reference count, so
we can safely unreference it every time.

(cherry picked from commit e980fe6071)
Now that we have the data available, we need to expose it to the
shaders. We can reuse the same vertex element that we use for
gl_VertexID, but we need to back it by an actual vertex buffer.
A hardware restriction requires that vertex attributes coming from a
buffer (STORE_SRC) must come before any other types (i.e. STORE_0).
So, we have to make gl_BaseVertex be the .x component of the vertex
attribute. This means moving gl_VertexID to a different component.
I chose to move gl_VertexID and gl_InstanceID to the .z and .w
components, respectively, to make room for gl_BaseInstance in the .y
component (which would also come from a buffer, and therefore be
STORE_SRC).

This patch fixes use of Altivec pack intrinsics on little-endian PowerPC
systems. Since little-endian operation only affects the load and store
instructions, the semantics of pack (and other) instructions that take
two input vectors implicitly change: the pack instructions still fill
a register placing values from the first operand into the "high" parts
of the register, and values from the second operand into the "low" parts
of the register, but since vector loads and stores perform an endian swap,
the high parts end up at high memory addresses.
To still achieve the desired effect, we have to swap the two inputs to
the pack instruction on little-endian systems. This is done automatically
by the back-end for instructions generated by LLVM, but needs to be done
manually when emitting intrisincs (which still result in that instruction
being emitted directly).
