Adds a transformation step to the post processing step.
Two modes are available:
1) keep
- Keeps samplers, textures and sampled textures as is
2) transform pure texture into sampled texture and remove pure samplers
- removes all pure samplers
- transforms all pure textures into its sampled counter part

Name mangling did not account for the vector size in the template type of a texture.
This adds that. The mangle is as it ever was for the vec4 case, which leaves
all GLSL behavior and most HLSL behavior uneffected. For vec1-3 the size is added
to the mangle.
Current limitation: textures cannot presently be templatized on structured types,
so this works only for vectors of basic types.
Fixes#895.
OpSpecConstantOp contains an embedded opcode which is given as a literal
argument to the OpSpecConstantOp. The subsequent arguments are as the
embedded op would expect, which may be a mixture of IDs and literals. This
adds support for that to the remapper binary parser. Upon seeing such an
embedded op, the parser flips over to parsing the argument list as
appropriate for that opcode.
Fixes#882.
Also, provides an option to auto-assign locations.
Existing tests use this option, to avoid the error message,
however, it is not fully implemented yet.
This modifies function parameter passing to pass the counter
buffer associated with a struct buffer to a function as a
hidden parameter. Similarly function declarations will have
hidden parameters added to accept the associated counter buffers.
There is a limitation: if a SB type may or may not have an associated
counter, passing it as a function parameter will assume that it does, and
the counter will appear in the linkage whether or not there is a counter
method used on the object.
Marking as WIP since it might deserve discussion or at least explicit consideration.
During type sanitization, the TQualifier's TBuiltInVariable type is lost. However,
sometimes it's needed downstream. There were already two methods in use to track
it through to places it was needed: one in the TParameter, and one in a map in the
HlslParseContext used for structured buffers.
The latter was going to be insufficient when SB types with counters are passed to
user functions, and it's proving awkward to track the data to where it's needed.
This PR holds a proposal: track the original declared builtin type in the TType,
so it's trivially available where needed.
This lets the other two mechanisms be removed (and they are in this PR). There's a
side benefit of not losing certain types of information before the reflection interface.
This PR is only that proposal, so it changes no test results. If it's acceptable,
I'll use it for the last piece of SB counter functionality.
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.
