* First attempt at a Linux build
- Fix up places where C++ idioms were written assuming lenient behavior of Microsoft's compiler
- Add a few more alternatives for platform-specific behavior where Windows was the only platform accounted for.
- Add a basic Makefile that can at least invoke our build, even if it isn't going good dependency tracking, etc.
- Build `libslang.so` and `slangc` that depends on it, using a relative `RPATH` to make the binary portable (I hope)
- Add an initial `.travis.yml` to see if we can trigger their build process.
* Fixup: const bug in `List::Sort`
I'm not clear why this gets picked up by the gcc *and* clang that Travis uses, but not the (newer) gcc I'm using on Ubuntu here, but I'm hoping it is just some missing `const` qualifiers.
* Fixup: reorder specialization of "class info"
Clang complains about things being specialized after being instantiated (implicilty), and I hope it is just the fact that I generate the class info for the roots of the hierarchy after the other cases. We'll see.
* Fixup: add `platform.cpp` to unified/lumped build
* Fixup: Windows uses `FreeLibrary`
and not `UnloadLibrary`
* Fixup: fix Windows project file to include new source file
This obviously points to the fact that we are going to need to be generating these files sooner or later.

Fixes #23
Up to this point, the compiler has used the ordinary `String` type to represent declaration names, which means a bunch of lookup structures throughout the compiler were string-to-whatever maps, which can reduce efficiency.
It also means that things like the `Token` type end up carying a `String` by value and paying for things like reference-counting.
This change adds a `Name` type that is used to represent names of variables, types, macros, etc.
Names are cached and unique'd globally for a session, and the string-to-name mapping gets done during lexing.
From that point on, most mapping is from pointers, which should make all the various table lookups faster.
More importantly (possibly), this brings us one step closer to being able to pool-allocate the AST nodes.

- `ExpressionSyntaxNode` becomes `Expr`
- `StatementSyntaxNode` becomes `Stmt`
- `StructSyntaxNode` becomes `StructDecl`
- `ProgramSyntaxNode` becomes `ModuleDecl`
- `ExpressionType` becomes `Type`
- Existing fields names `Type` become `type`
- There might be some collateral damage here if there were, e.g., `enum`s named `Type`, but I can live with that for now and fix those up as a I see them

The change is mostly about trying to make sure the compiler "fails safe" when it encounters an internal assumption that isn't met.
Most internal errors will now throw exceptions (yes, exceptions are evil, but this will work for now), and these get caught in `spCompile` so that they don't propagate to the user (they just see a message that compilation aborted due to an internal error).
Subsequent changes are going to need to work on diagnosing as many of these situations as possible, so that users can at least know what construct in their code was unexpected or unhandled by the compiler.

Fixes #94
We'd been handling HLSL `Buffer` and `RWBuffer` in a one-off fashion, and that led to a lot of code duplication, and also to the issue that we weren't handling `RasterizerOrderedBuffer` at all.
This change basically folds `Buffer` in so that it is conceptually a texture type (just with a unique shape). Hopefully all the other logic still works.

Fixes #15
These are the modifiers like:
layout(local_size_x = 16) in;
Unlike the HLSL case, these don't get attache to the entry point function itself, so there is a bit more work involed in looking them up.
Just to make sure I didn't mess up the HLSL case, I went ahead and added two tests for this capability: one for GLSL and one for HLSL.

Fixes #84
- When computing resource usage for an array type, don't multiply the resource usage of the element type by the element count foor descriptor-table-slot resources.
- When reporting the "stride" of an array type through reflection, report the stride for descriptor table slots as zero, always.

- This really just checks two basic things:
1. Was there any global variable declared with `in` and `sample`?
2. Did any code encountered during lowering referenece `gl_SampleIndex`?
- This doesn't cover what HLSL could need, nor what we would need for cross-compilation. Consider it GLSL-specific for now.
- In order to generate the information with even a reasonable chance of being accurate (not giving a ton of false positives) I tried to integrate the checks into the lowering process (so they only see code that is referenced, one hopes).
- For this to work with my testing setup, I needed to make sure that lowering is always performed, prior to emitting reflection info
- This change broke several reflection tests, because they had been using code that wouldn't actually pass the downstream compiler. I checked in fixes for those.

- This also adds reflection API for querying:
- Entry point name
- Entry point parameter list

- Try to handle `ErrorType` gracefully when computing type layouts
- When outputting a `TypeExp`, if the type part is errorneous (or missing), try to use the expression part
- Make sure to lower the expressions side of a `TypeExp` during lowering
|

|
|
|

- Expand most queries that handle `TextureType` to handle `TextureTypeBase`, in hopes that this covers most uses of `image*` types in Vulkan GLSL
- Adopt the quick fix from Falcor to return read-write access for shader-storage-block types. Something more comprehensive is probably needed if people want to do queries on these, since constant buffers should really be included, then.

These are mostly copy-pasted from the existing `cbuffer` support, so there might be details I'm missing.

This logic hadn't been updated for Vulkan GLSL.

The code should now compile cleanly with warnings as errors for VS2015 with `W3`.
Most of the changes had to do with propagating a real pointer-sized integer type through code that had been using `int`.
|
| |
|
|
|
|
|
| |
The lexer was creating an `unsigned long long` value, and then the AST was storing it in an `int`.
This change makes both use a `long long`.
This is obviously still a stopgap until I can get arbitrary precisions in here.

For context: a `DeclRef` is supposed to capture both a pointer to a particualr declaration, and also any information needed to specialize that declaration for a context (e.g., generic parameter substitutions).
The existing approach had a hiearchy of specialized decl-ref types that mirrored the AST hierarchy, but that led to a lot of boilerplate where you had to recapitulate the exact same hierarchy.
The new appraoch basically treats `DeclRef<T>` as a sort of "smart pointer" in that it wraps a pointer to a `T` (the declaration), plus a side field for the specialization info, and then allows it to be cast as needed to other types (where the pointer cast would be allowed), while carrying along the side info.
To enable this, all the things that used to be member functions of declaration-reference types are now free functions that take a `DeclRef<T>` for some specific `T` as a parameter.

This gets rid of one unecessary namespace.
