Current blorp logic issues unconditional "flush everything"
(see brw_emit_mi_flush()) after each render. For example, all
blits issue this unconditionally which shouldn't be needed if
they set render cache properly so that subsequent renders do
necessary flushing before drawing.
In case of piglit:
ext_framebuffer_multisample-accuracy all_samples depth_draw small
intel_hiz_exec() is always preceded by blorb blit and the
unconditional flush looks to hide the lack of stall and flushes
in depth clears. By removing the brw_emit_mi_flush() I get gpu
hangs.
This patch adds the stalls and flushes mandated by the spec
and gets rid of those hangs.
v2 (Jason, Ken): Document the rational for separating
depth cache flush and stall on Gen7.

At the moment we support 5+ different implementations each with varying
amount of bugs - from thread safely problems [1], to outright broken
implementation(s) [2]
In order to accommodate these we have 150+ lines of configure script and
extra two configure toggles. Whist an actual implementation being
~200loc and our current compat wrapping ~250.
Let's not forget that different people use different code paths, thus
effectively makes it harder to test and debug since the default
implementation is automatically detected.
To minimise all these lovely experiences, import the "100% Public
Domain" OpenBSD sha1 implementation. Clearly document any changes needed
to get building correctly, since many/most of those can be upstreamed
making future syncs easier.
As an added bonus this will avoid all the 'fun' experiences trying to
integrate it with the Android and SCons builds.

Furthermore it seems that some games (or surrounding runtime) static
link against OpenSSL resulting in conflicts. For more information see

The implementation was added with commit d085a5dff5 and effectively

Namely: the codepath used was determined solely during build time. Thus
if we built again new wayland and then run against older (yet still
within the requirements, as per the configure) one will get undefined
symbols.
As of earlier commit 36b9976e1f "egl/wayland: Avoid race conditions

A number of games have large arrays of constants, which we promote to
uniforms. This introduces copies from the uniform array to the original
temporary array. Normally, copy propagation eliminates those copies,
making everything refer to the uniform array directly.
A number of shaders in "Deus Ex: Mankind Divided" recently exposed a
limitation of copy propagation - if we had any intrinsics (i.e. image
access in a compute shader), we weren't able to get rid of these copies.
That meant that any variable indexing remained on the temporary array
rather being moved to the uniform array. i965's scalar backend
currently doesn't support indirect addressing of temporary arrays,
which meant lowering it to if-ladders. This was horrible.
According to Marek, on radeonsi/GCN, "F1 2015" uses 64% less
spilled-temp-array memory.
On i965/Skylake:

Helps Deus Ex: Mankind Divided. The one shader with hurt spills/fills
is from Tomb Raider at Ultra settings, but that same shader has a

so it seems like a win there as well.

Image atomics, for example, return a value - but the shader may not
want to use it. We assigned a useless VGRF destination. This seemed
harmless, but it can actually be quite harmful. The register allocator
has to assign that VGRF to a real register. It may assign the same
actual GRF to the destination of an instruction that follows soon after.
This results in a write-after-write (WAW) dependency, and stall.
A number of "Deus Ex: Mankind Divided" shaders use image atomics, but
don't use the return value. Several of these were hitting WAW stalls
for nearly 14,000 (poorly estimated) cycles a pop. Making dead code
elimination null out the destination avoids this issue.
This patch cuts one shader's estimated cycles by -98.39%! Removing the
message response should also help with data cluster bandwidth.

In theory we might have incorrectly NOP'd instructions that write the
flag, but where that flag value isn't used, and yet the instruction
either writes the accumulator or has side effects.
I don't believe any such instructions exist, so this is mostly a
code cleanup.
Curro pointed out that FS_OPCODE_FB_WRITE has a null destination and
actually writes the flag on Gen4-5 to dynamically decide whether to
write some payload data. The hunk removed in this patch might have
NOP'd it, except that we don't actually mark flags_written() in the
IR, so it doesn't think the flag is touched at all. That's sketchy,
but it means it wouldn't hit this today (though there are likely other
problems!).
v2: Properly replace the inst->regs_written() check in the second
hunk with the flag being live (mistake caught by Curro).

According to Matt, the dead code pass explicitly avoided IF and WHILE
because on Sandybridge, these could have conditional modifiers and
null destination registers. Normally, those instructions use BAD_FILE
for the destination register. Nowadays, we don't do that anymore, so
we could technically drop these checks.
However, it's clearer to explicitly leave control flow instructions
alone, so change it to the more generic !inst->is_control_flow().
This should have no actual change.
