Using brw_imm_* creates a source with file=HW_REG, and the scheduler
inserts barrier dependencies when it sees HW_REG. None of these are
hardware-registers in the sense that they're special and scheduling
shouldn't touch them. A few of the modified cases already have HW_REGs
for other sources, so it won't allow extra flexibility in some cases.

In the presence of LLVM the final library exports every symbol from
the llvm namespace. Resolve this by using a version script (w/o the
version/name tag).
Considering that there are only ~35 symbols, explicitly list them

Without this, I get linking failures (static linking).
The static linking is sort of required for me, because otherwise Steam and
applications using the Steam runtime regularily fail because my LLVM was
compiled and linked against a newer libgcc_s, libstdc++, etc. and uses
features from those newer versions. And instead of Steam just not
starting, my X starts crashing, whenever libGL fails to load a (32 bit)
driver.
Since I hate crashes of X and I don't think Valve/Steam will behave like
a proper distribution soon (rebuilds versus current Debian Testing, since
they base their Steam OS off that), I need a radeonsi which carries its
own LLVM within and doesn't care about what the runtime sets. This means
linking Mesa statically.

If we make ann_count non-zero, annotation_finalize() won't bail.
Not modifying it seems to make the code more clear than would modifying
annotation_finalize().
This reverts commit a6860100b8.
Why this code didn't work in all circumstances is unknown and without a
working Ironlake simulator (which uses a different AUB format) we'll
probably never know, short of a lot of experimentation, and spending a
bunch of time to try to optimize a few instructions on Ironlake is not
time well spent.
Moreover, for mix(vec4, vec4, vec4) using the accumulator introduces a
dependence between the otherwise independent per-component calculations.
Not using the accumulator, even if it means an extra instruction per
component might be preferable. We don't know, we don't have data, and
we don't have the necessary register on Ironlake for shader_time to tell
us.

Will be used to print disassembly after jump targets are set and
instructions are compacted, while still retaining higher-level IR
annotations and basic block information.
An array of 'struct annotation' will live along side the generated
assembly. The generators will populate the array with their IR
annotations, and basic block pointers if the instructions began or ended
a basic block pointer.
We'll then update the instruction offset when we compact instructions
and then using the annotations print the disassembly.

The DO instruction doesn't exist on Gen6+. Since before this commit, DO
always ended a basic block, if it also happened to start one (e.g., a
while loop inside an if statement) the block containing only the DO
would actually contain no hardware instructions.
Pre-Gen6's WHILE instructions jumps to the instruction following the DO,
so strictly speaking we won't be modeling that properly, but I claim
there is actually no functional difference.
This will simplify an upcoming change where we want to mark the first
hardware instruction in the loop as beginning a block, and the last
instruction before the loop as ending one.

The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy. This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context. The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.
But ARB_robustness spec says:
If a reset status other than NO_ERROR is returned and subsequent calls
return NO_ERROR, the context reset was encountered and completed. If a
reset status is repeatedly returned, the context may be in the process
of resetting.
8. How should the application react to a reset context event?
RESOLVED: For this extension, the application is expected to query the
reset status until NO_ERROR is returned. If a reset is encountered, at
least one *RESET* status will be returned. Once NO_ERROR is
encountered, the application can safely destroy the old context and
create a new one.
The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned. But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed. For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.
The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context. Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.

Define GLX_USE_APPLEGL, as config/darwin used to, to turn on specific code to
use the applegl direct renderer
Convert src/glx/apple/Makefile to automake
Since the applegl libGL is now built by linking libappleglx into libGL, rather
than by linking selected files into a special libGL:
- Remove duplicate code in apple/glxreply.c and apple/apple_glx.c. This makes
apple/glxreply.c empty, so remove it
- Some indirect rendering code is already guarded by !GLX_USE_APPLEGL, but we
need to add those guards to indirect_glx.c, indirect_init.c (via it's
generator), render2.c and vertarr.c so they don't generate anything
Fix and update various includes
glapi_gentable.c (which is only used on darwin), should be included in shared
glapi as well, to provide _glapi_create_table_from_handle()
Note that neither swrast nor indirect is supported in the APPLEGL path at the
moment, which makes things more complex than they need to be. More untangling
is needed to allow that

The HAVE_DRI automake conditional is retired in favour of a number of other
conditionals:
HAVE_DRI2 enables building of code using the DRI2 interface (and possibly DRI3
with HAVE_DRI3)
HAVE_DRISW enables building of DRI swrast
HAVE_DRICOMMON enables building of target-independent DRI code, and also enables
some makefile cases where a more detailled decision is made at a lower level.
HAVE_APPLEDRI enables building of an Apple-specific direct rendering interface,
still which requires additional fixing up to build properly.
