This implements mytex.mips[mip][coord] for texture types. There is
some error testing, but not comprehensive. The constructs can be
nested, e.g in this case the inner .mips is parsed before the completion
of the outer [][] operator.
tx.mips[tx.mips[a][b].x][c]
Using GS methods such as Append() in non-GS stages should be ignored, but was
creating errors due to the lack of a stream output symbol for the non-GS stage.
The codebase seems to use both “#pragma once“ approach, and “#ifndef / #define” approach,
so I picked pragma once as that one is less typing & less brittle.
When glslang is built with some other build system and lumped/unity builds are used,
without the include guards some headers would get included multiple times, leading to duplicate
declaration errors.
When glslang is built with some other build system and lumped/unity builds are used,
without the checks this would get “macro is being redefined” warnings/errors.
This adds infrastructure suitable for any front end to create SPIR-V loop
control flags. The only current front end doing so is HLSL.
[unroll] turns into spv::LoopControlUnrollMask
[loop] turns into spv::LoopControlDontUnrollMask
no specification means spv::LoopControlMaskNone
This reverts commit cfc69d95afed34e1ba1371df0ddb56f2f491a5cb.
* Change CMAKE_INSTALL_PREFIX default on Windows in order
to prevent permission denied errors when trying to install
to "Program Files".
* Use `GNUInstallDirs` in order to respect GNU conventions.
This is especially important for multi-arch/multi-lib setups.
* Specify position independent mode building properly, without
using the historic hack of adding `-fPIC` as a definition.
This makes the build system more portable.
* Only detect C++ (and not C) to slightly speed up configuring.
* Specify C++11 mode using modern CMake idioms.
* Fix some whitespace issues.
Adds a notification phase to the io remapper.
The idea behind this is to give the user a
chance to group uniforms and/or in/out variables
for a better pipeline layout sharing for vulkan.

Multisample textures support a GetSamplePosition() method intended to query
positions given a sample index. This cannot be truly implemented in SPIR-V,
but #753 requested returning standard positions for the 1..16 cases, which
this PR adds. Anything besides that returns (0,0). If the standard positions
are not used, this will be wrong.
This should be revisited when there is a real query available.

Vector conditions properly convert the true/false expression types to same
width vector as the condition.
Scalar conditions make the true/false expressions convert to each other.
Byte address buffers were failing to detect that they were byte address
buffers when used as fn parameters.
Note: this detection is a little awkward, and could be simplified if
it was easy to obtain the declared builtin type for an object.
Adds --hlsl-iomap option to perform IO mapping in HLSL register space.
--shift-cbuffer-binding is now a synonym for --shift-ubo-binding.
The idea way to do this seems to be passing in a dedicated IO resolver, but
that would require more intrusive restructuring, so maybe best for its
own PR.
The TDefaultHlslIoResolver class and the former TDefaultIoResolver class
share quite a bit of mechanism in a common base class.
TODO: tbuffers are landing in the wrong register class, which needs some
investigation. They're either wrong upstream, or the detection in the
resolver is wrong.
