The nir_lower_source_mods pass does a weak form of copy propagation to
clean up all of the mov-with-negate's that get generated. However, we
weren't properly checking that the sources were SSA and so we could end up
moving a register read which is not, in general, valid.

The old code wasn't correctly handling the case where the new value of the

Previously, this function returned the number of elements for structures
and arrays and 0 for everything else. In NIR, this is almost never what
you want because we also treat matricies as arrays so you have to
special-case constantly. This commit glsl_get_length treat matrices
as an array of columns by returning the number of columns instead of 0
This also fixes a bug in locals_to_regs caused by not checking for the
matrix case in one place.
v2: Only special-case for matrices and return a length of 0 for vectors as
we did before. This was needed to not break the TGSI-based drivers and
doesn't really affect NIR at the moment.

This should be more efficient than the previous snprintf() solution.
But more importantly, it avoids a buffer overflow bug that could result
in crashes or unpredictable results when processing very large interface
blocks.
For the app in question, key->length = 103 for some interfaces. The check
if size >= sizeof(hash_key) was insufficient to prevent overflows of the
hash_key[128] array because it didn't account for the terminating zero.
In this case, this caused the call to hash_table_string_hash() to return
different results for identical inputs, and then shader linking failed.
This new solution also takes all structure fields into account instead
of just the first 15 when sizeof(pointer)==8.

Android 5.0 allows modules to generate source into $OUT/gen, which will
then be copied into $OUT/obj and $OUT/obj_$(TARGET_2ND_ARCH) as necessary.
Modules will need to change calls to local-intermediates-dir into
local-generated-sources-dir.
The patch changes local-intermediates-dir into local-generated-sources-dir.
If the Android version is less than 5.0, fallback to local-intermediates-dir.
The patch also fixes the 64-bit building issue of Android 5.0.

`interface` is a define on Windows -- an alias for `struct` keyword,
used when declaring COM interfaces in C or C++.
So use instead `programInterface`, therefore matching the name used
in GL_ARB_program_interface_query spec/headers, which was renamed exactly
for the same reason:
"Revision 10, May 10, 2012 (pbrown)
- Rename the formal parameter <interface> used by the functions in this
extension to <programInterface>. Certain versions of the Microsoft
C/C++ compiler and/or its headers cause "interface" to be treated as a
reserved keyword."
Trivial.
Patch adds ProgramResourceList to gl_shader_program structure.
List contains references to active program resources and is
constructed during linking phase.
This list will be used by follow-up patches to implement hooks
for GL_ARB_program_interface_query. It can be also used to
implement any of the older shader program query APIs.

When a vec has more elements than row components in a matrix, the
code could end up failing an assert inside assign_to_matrix_column().
This patch makes sure that when there is still room in the matrix for
more elements (but in other columns of the matrix), the data is actually
assigned.

Storing this here is pretty sketchy - I don't know if any driver other
than i965 will want to use it. But this will make it a lot easier to
generate NIR code at link time. We'll probably rework it anyway.
(Ian suggested making nir_assign_var_locations_scalar_direct_first
simply modify the nir_shader's fields, rather than passing pointers
to them. If this stays long term, we should do that. But Jason and
I suspect we'll be reworking this area again in the near future.)

I guess I was looking too much at how lower_system_values worked when
writing lower_idiv.
Since ttn wasn't emitting load_var for sysvals and the only drivers
using lower_idiv were using ttn, I think nothing was broken as a result.
But might as well fix this before it becomes a problem.

This pass performs a mark and sweep pass over a nir_shader's associated
memory - anything still connected to the program will be kept, and any
dead memory we dropped on the floor will be freed.
The expectation is that this will be called when finished building and
optimizing the shader. However, it's also fine to call it earlier, and
many times, to free up memory earlier.
v2: (feedback from Jason Ekstrand)
- Skip sweeping impl->start_block, as it's already in the CF list.
- Don't sweep SSA defs (they're owned by their defining instruction)
- Don't steal phi sources (they're owned by nir_phi_instr).
- Don't steal tex->src (it's owned by the tex_inst itself)
- Don't sweep dereference chains (top-level dereferences are owned by
the instruction; sub-dereferences are owned by the parent deref).
- Don't sweep sources and destinations (SSA defs are handled as part of
the defining instruction, and registers are handled as part of
function implementations).
- Just steal instructions; don't walk them (no longer required).
v3: (feedback from Jason Ekstrand)
- Steal indirect sources from nir_src/nir_dest.
