framework for passes to process them. (#2297)
* Added a decorator to mark functions for forward-mode differentiation
* Fill out support for calls to non-decl values
The existing compiler logic has a few places (semantic checking plus AST-to-IR lowering) where it assumes that function calls (`InvokeExpr`) are only ever made to expressions that resolve to a specific `Decl` (`DeclRefExpr`). This assumption allows semantic checking and lowering code to inspect things like the parameter list of an actual declaration, rather than just the type signature of the callee, and that infrastructure is used to support various features (e.g., default argument values on parameters).
The AST and IR representations themselves have no matching requirement, and the places where the more general case of call expressions would need to be supported were relatively clear in the code. This change attempts to add suitable logic into each of those places.
Note that this change does *not* surface any valid way to form input code that would cause these new code paths to be executed, so it is entirely possible that there are bugs in the logic as written here. The primary goal of this change is simply to get a sketch of the correct code checked in so that we have something to build on once we have language features that will require this support.

* Use IR pass to eliminate phi nodes
"Phi nodes" are one of the key contrivances that makes SSA (Static
Single Assignment) form work. Because SSA is so great for compiler
IRs, we kind of need to deal with phi nodes, but they also get in
the way because they don't have a direct analog in most lower-level
machine ISAs or execution models, nor in most of the high-level
languages a transpiler wants to emit. As a result a compiler like
ours needs to be able to eliminate the phi nodes from a program as
part of generating output code.
(For any clever people noting that SPIR-V supports phi nodes
directly: yes, it does. It doesn't need to and it probably *shouldn't*.
Anybody involved in the decision-making knows my reasoning, and
anybody else should feel free to ask me if they want the lecture.
Anyway...)
The basic idea of elimiating phi nodes is simple enough. We replace
each phi node with a temporary variable. Uses of the phi use values
loaded from the temporary. The operation of the phi itself
(assigning a value based on the branch taken) amounts to an assignment
into the temporary.
Previously, the Slang compiler dealt with phi nodes very late in
the process of generating code: in the middle of emitting strings
of source code in a high-level language like HLSL or GLSL. Doing the
work that late in compilation has two big drawbacks:
1. Our ability to emit clean and/or optimal code is limited because
we may not be able to make certain changes to the IR, or because we
cannot make use of additional information like a dominator tree that
might be available at other points in compilation.
2. Any other IR passes that relate to temporary variables won't be
able to see the variables that we generate for phi nodes. This could
raise issues with correctness (e.g., if we want to compute live-range
information for *all* temporary variables), or performance (we have no
way to run additional IR optimization passes after phis are eliminated).
This change addresses these problems by making the elimination of
phi nodes an explicit IR pass. Additional optimizations can easily be
run after this pass (although we'd need to be careful not to run
passes that could end up introducing new phis). The pass makes use
of the information available to it to try to produce code that will
emit to "clean" HLSL/GLSL.
The core of the pass is in `slang-ir-eliminate-phis.cpp`, and is
heavily commented, so I won't describe the approach in detail here.
There are two related issues that came up, though:
First, it turned out that our emit logic for local variables (`IRVar`
instructions) wasn't using the function we'd defined named `emitVar()`.
One worrying consequence of that oversight was that the `precise`
modifier would impact generated HLSL/GLSL for variables that turned
into SSA values (including phi nodes), but *not* for local variables
that had not been SSA'd (or that had been SSA'd and then de-SSA'd).
This change also fixes that bug; it is unclear how widespread the
impact of the original issue might be.
Second, generating explicit IR temporaries for phi nodes exposed a
pre-existing bug in the `slang-ir-restructure-scoping` pass. That pass
basically detects cases where we have an instruction `I` with a use
`U` such that the use follows the rules of SSA form ("def dominates
use," meaning `I` dominations `U`), but does not follow the more
restrictive scoping rules of high-level-language output (where a value
computed "inside" a loop is not automatically visible to code outside
the loop just because it dominates that code). That pass did not
correctly account for the case where `I` was a temporary variable.
It seems that case could not arise before now because we didn't have
any passes that would move `var`, `load`, or `store` operations out
of the basic block they started in. The fix for that pass was relatively
simple, and will make the whole thing more robust in case we add more
aggressive optimizations later.

An earlier refactoring pass over the compiler codebase split the
type that had been called `CompileRequest` into three distinct
pieces:
* `FrontEndCompileRequest` which was supposed to own state and
options related to running the compiler front end and producing
IR + reflection (e.g., what translation units and source
files/strings are included).
* `BackEndCompileRequest` which was supposed to own state and options
related to running the compiler back end to translate the IR
for a `ComponentType` (program) into output code. (Note that the
`BackEndCompileRequest` was conceived of as orthogonal to the
`TargetRequest`s, which store per-target and target-specific
options.)
* `EndToEndCompileRequest` which was an umbrella object that owns
separate front-end and back-end requests, plus any state that is
only relevant when doing a true end-to-end compile (such as the
kinds of compiles initiated with `slangc`). As originally conceived,
the only state that this type was supposed to own was stuff related
to "pass-through" compilation, as well as state related to writing
of generated code to output files.
That refactoring work was very useful at the time, because it allowed
us to "scrub" the back end compilation steps to remove all
dependencies on front-end and AST state (this was important for our
goals of enabling linking and codegen from serialized Slang IR).
At this point, however, it is clear that the hierarchy that was built
up serves very little purpose:
* The `BackEndCompileRequest` type is only used in two places:
* As part of an `EndToEndCompileRequest`, where the settings on
the `BackEndCompileRequest` can be configured, but only through
the `EndToEndCompileRequest`
* As part of on-demand code generation through the `IComponentType`
APIs. In this case, the settings stored on the
`BackEndCompileRequest` are not accessible to the application
at all, and will always use their default values, so that
instantiating a "request" object doesn't really make any sense.
* The `FrontEndCompileRequest` type has a similar situation:
* Front-end compilation as part of an `EndToEndCompileRequest`
supports user configuration of `FrontEndCompileRequest` settings,
but only through the `EndToEndCompileRequest`
* Front-end compilation triggered by an `import` or a `loadModule()`
call does not support user configuration of settings at all. It
will always derive all relevant settings from thsoe on the
session ("linkage").
In addition, subsequent changes have been made to the compiler that
show a bit of a "code smell" and/or forward-looking worries for this
decomposition:
* In some cases we've had to add the same setting to multiple types
in the breakdown (front-end, back-end, end-to-end, linkage, target,
etc.) which makes it harder for us to validate that all the possible
mixtures of state work correctly.
* Related to the above, in some cases we have manual logic that copies
state from one of the objects in the breakdown to another, in order
to ensure that the user's intention is actually followed.
* As a forward-looking concern, it seems that developers have sometimes
added new configuration options and state to places that don't really
make sense according to the rationale of the original decomposition
(e.g., we probably don't want to have a lot of state that is only
available via end-to-end requests, given that the API structure is
meant to push users *away* from end-to-end compiles).
As a result of all of the above, I've been planning a large refactor
with the following big-picture goals:
* Eliminate `BackEndCompileRequest`
* Move all relevant state/options from the back-end request to
the end-to-end request, since that is the only place they could
be set anyway.
* Introduce a transient "context" type to be used for the duration
of code generation that serves the main functions that back-end
requests really served in the codebase
* Make `EndToEndCompileRequest` be a subclass of
`FrontEndCompileRequest`
* Consider addding a transient "context" type for front-end
compiles that can be used in `import`-like cases rather than
needing a full front-end request object. If this works, then
eliminate `FrontEndCompileRequest` and be back to world with
just a single `CompileRequest` type
* Move *all* compiler configuration options to a distinct type (named
something like `CompilerConfig` or `CompilerOptions` or whatever)
which stores setting as key-value pairs, and has a notion of
"inheritance" such that one configuration can extend or build on top
of another. Make all the relevant types use this catch-all structure
instead of redundantly storing flags in many places.
This change deals with the first of those bullets: removeal of
`BackEndCompileRequest`. The addition of the `CodeGenContext` type is
perhaps an unncessary additional step, but making that change helps
clean up a bunch of the code related to per-target code generation,
so I think it is the right choice.

Recent work that added support for translating DXR-style ray tracing shaders to work with OptiX seems to have accidentally applied its transformations even when compute shaders are translated for CUDA. As a result, compute entry points with `uniform` parameters at entry-point scope would be miscompiled to use OptiX calls that are not available for non-OptiX compiles.
This change fixes the relevant pass so that it correctly opts-out on compute entry points, and also unifies some pieces of code that were being shared between a few different IR passes but that had gotten copy-pasted for the OptiX case.
The fix has been confirmed by running relevant CUDA tests locally, but CUDA is still disabled in the default CI builds, so this change is not yet actively being tested to avoid further regression.

* Work to mitigate SPIR-V bloat
SPIR-V is not an especially compact format, but some patterns in how Slang generates code and then runs it through `spirv-opt` lead to many redundant field-by-field copy operations being emitted. This change attempts to address some of the resulting bloat from the Slang side of things.
Note: experimentation shows that the bloat is less pronounced when running either *no* SPIR-V optimizations or *full* SPIR-V optimizations, so it is also likely that the bloat should be addressed by changing which `spirv-opt` passes the Slang compiler runs in default (`-O1`) builds. Such changes should come as a distinct pull request.
This change primarily does two things:
First, the code generation strategy for passing arguments to `out` and `inout` parameters has been changed. In the past, the compiler would *always* copy the argument value into a temporary, then pass the address of the temporary, and then write back the value after the call. The new code generation strategy attempts to identify when an argument value already has a simple address in memory and passes that address directly when possible. This eliminates many copy operations that occur before/after calls to functions with `out`/`inout` parameters.
Second, we introduce an IR optimization pass that detects call sites where the entire contents of a buffer (usually a constant buffer) is being passed to a callee function, such that many bytes are loaded and then passed even if only very few are used in the callee. The pass moves the load operations from the caller to a specialized version of the the callee where possible (e.g., when the constant buffer in question is a global shader parameter). Doing this eliminates another major category of copies.
Notes:
* The IR lowering logic is complicated by the fact that several kinds of l-values (values that are usable as the desitnation of assignment, or for `out`/`inout` arguments) are not actually addressable. An easy example is a non-contiguous swizzle like `v.xwz` on a `float4`, where the value occupies 12 bytes, but not 12 consecutive bytes with a single address. There are many more corner cases like that and the IR lowering pass carries a lot of complexity to deal with them. A more systematic overhaul is due some time soon.
* The IR representation of `out` and `inout` parameters deserves some careful scrutiny when making these kinds of changes. The official semantics of `inout` in HLSL has been "copy in copy out" (and `out` is just "copy out") which is observably different from any solution that passes in the address of an l-value directly. By making this change we are saying that Slang's semantics are not precisely those of legacy HLSL, and that our semantics for `inout` parameters are closer to those of `inout` in Swift or of a mutable borrow in Rust. In the Swift case the implementation can freely pass the underlying storage of an l-value or the address of a temporary, and valid programs may not observe the different. It is thus illegal to observe the value in a storage local while a mutation to that location is "in flight." All of this is way more detailed and technical than 99% of Slang users will ever care about, but importantly it gives us semantic cover to eliminate these copies in the IR, and also to emit output C++ code that implements `out` and `inout` as by-reference parameter passing.
* There was an exsting generic pass for specializing functions based on call sites that uses a "template method" style of pattern to customize its behavior. That pass needed to be generalized to handle this use case because it had previously operated on the assumption that the "desire" to specialize a callee function must be driven by the parameter declarations of that function, and not on the argument values passed in. The code has been slightly refactored to allow the policy for specialization to consider both parameters and arguments.
* Unsurprisingly, a bunch of the GLSL (and thus SPIR-V) generated has changed with this work, so several baseline `.slang.glsl` files needed to be updated.
* This change is incomplete in that it does not address broader cases of buffer loads, including both partial loads from constant buffers (just loading one field, but a field that uses a "large" structure type), and loads from multi-element buffers (a lot from a structured buffer where the element type is "large"). The main question in each of those cases is how to define how "large" a structure needs to be before we decide to try and sink loads into callee functions like this. In the worst case, sinking loads in this way may actually create *more* memory traffic (because the same values get loaded in multiple callee functions).

* #include an absolute path didn't work - because paths were taken to always be relative.
* WIP diagnostics for line number output.
* Small param naming change
* Use x macro for pass through compile human name lookup/getting.
* WIP on parsing downstream compiler output.
* Split out parsing into ParseDiagnosticUtil.
Added test result of single line.
* Dump out the std output on fail to parse diagnostics.
* Change test type for syntax-error-intrinsic.slang be TEST not TEST_DIAGNOSTIC
* Use Index for StringUtil.
* WIP: First pass support for parsing Slang diagnostics.
* WIP Testing comparing with ParseDiagnosticUtil with previous ad-hoc mechanism.
* Use the new parsing mechanism for diagnostic comparisons.
* Fix layout on GLSL, doesn't have CR so runs into main.
* Split out switch on outputting intrinsic 'specials'.
Output code around intrinsic as emit - so that we get the appropriate indenting (and potentially other benefits).
* Improvements to diagnostics parsing.
Better error handling, and fallback handling.
Added ability to parse downstream compilers without a prefix.
Added ability to parse Slang with a prefix.
* DownstreamDiagnostic::Type -> Severity and related fixes.
* Small fixes around moving from DownstreamDiagnostic::Type -> Severity
* Fix handling of 'special intrinsic' expansion
* Split out the handling of intrinsic expansion into it's own type and files.
* Fixes to reading expected output - for SimpleLine test.
* Test using += to check #line output.
* A test around += and return.
* Small comment fixes.

This change also switches the build back to using prebuilt glslang binaries instead of always building from source.

* Update glslang to 11.1.0
This change pulls new versions of glslang, spirv-headers, and spirv-tools as submodules, and makes the necessary changes to other files in the repository to get it all building (at least on Windows).
This change also enables building of glslang from source by default, so that we can easily generate new binaries for inclusion in the `slang-binaries` repository.
* fixup: missing file
