From page 14 (page 20 of the PDF) of the GLSL 1.10 spec:
"In addition, all identifiers containing two consecutive underscores
(__) are reserved as possible future keywords."
The intention is that names containing __ are reserved for internal use
by the implementation, and names prefixed with GL_ are reserved for use
by Khronos. Names simply containing __ are dangerous to use, but should
be allowed.
Per the Khronos bug mentioned below, a future version of the GLSL

Section 3.3 (Preprocessor) of the GLSL 1.30 spec (and later) and the
GLSL ES spec (all versions) say:
"All macro names containing two consecutive underscores ( __ ) are
reserved for future use as predefined macro names. All macro names
prefixed with "GL_" ("GL" followed by a single underscore) are also
reserved."
The intention is that names containing __ are reserved for internal use
by the implementation, and names prefixed with GL_ are reserved for use
by Khronos. Since every extension adds a name prefixed with GL_ (i.e.,
the name of the extension), that should be an error. Names simply
containing __ are dangerous to use, but should be allowed. In similar
cases, the C++ preprocessor specification says, "no diagnostic is
required."
Per the Khronos bug mentioned below, a future version of the GLSL
specification will clarify this.

Linking with LLVM static libraries is easily broken by changes to
the llvm-config program or when LLVM adds, removes, or changes library
components. Keeping up with these changes requires a lot of maintanence
effort to keep the build working on the master and stable branches.
Also, because of issues in the past LLVM static libraries, the release
manager is currently configuring with --with-llvm-shared-libs when
checking the build before release. Enabling shared libraries by
default would allow the release manager to run ./configure with
no arguments, and be reasonably confident that the build would succeed.

And define non-mutating helper functions to retype fixed and normal

::fixed_hw_reg completely and have fixed regs use the normal register
data members (e.g. backend_reg::reg to select a fixed GRF number,
src_reg::swizzle to store the swizzle, etc.), I have the feeling that
this is not the last headache we're going to get because of the
multiple ways to represent the same thing and the different register
interface depending on the file a register is stored in...

Broadwell's 3DSTATE_WM_HZ_OP packet makes this much easier.
Instead of programming the whole pipeline, we simply have to emit the
depth/stencil packets, a state override, and a pipe control. Then
arrange for the state to be put back. This is easily done from a single
function.
v2: Use minify(mt->logical_{width,height}0, level) in 3DSTATE_WM_HZ_OP
instead of intel_mipmap_level's width/height fields. Those were
based on the physical width/height, and thus wrong for MSAA buffers.
Eric also deleted those fields.
v3: Use 0xFFFF as the sample mask regardless of what the user set (as
this operation is unrelated); set the drawing rectangle to the
miplevel being operated on, rather than the whole surface; remove
unnecessary MAX2(..., 1) around mt->logical_depth0 (all suggested
by Eric Anholt).

The existing code followed the vtable function signature, which is not a
great fit: many of the parameters are unused, and the function still
inspects global state, making it less reusable.
This patch refactors the depth buffer packet emission code into a new
function which takes exactly the parameters it needs, and which uses no
global state. It then makes the existing vtable function call the new
one.
Ideally, we would remove the vtable function, and clean up that
interface. But that can happen once HiZ is working.
