<id>urn:sha1:f02b08490aa905f42a8d90381db84b1f8e409c0c</id>
<content type='text'>
Changes default for render-test to sm_6_5.
Since sm_6_5 is the new default, remove the -use-dxil option, add
-use-dxcb option
Remove -use-dxil option from all test cases.
Add -use-dxcb to two tests that needed it.

<title>Convert more tests to use shader objects (#1659)</title>

<id>urn:sha1:2a5d5b32348c33aac7ca62aa9a4c2bb7cff8e08a</id>
<content type='text'>
This change converts a large number of our existing tests to use the `ShaderObject` support that was added to the `gfx` layer.

In many cases, tests were just updated to pass `-shaderobj` and the result Just Worked.
In other cases, a `name` attribute had to be added to one or more `TEST_INPUT` lines.

For tests that did not work with shader objects "out of the box," I spent a little bit of time trying to get them work, but fell back to letting those tests run in the older mode.
Future changes to the infrastructure will be needed to get those additional tests working in the new path.

Along with the changes to test files, the following implementation changes were made to get additional tests working:

* Because the shader object mode uses explicit register bindings (from reflection), the hacky logic that was offseting `u` registers for D3D12 based on the number of render targets gets disabled (by another hack).

* The "flat" reflection information coming from Slang was not correctly reporting "binding ranges" for things that consumed only uniform data (which would be everything on CUDA/CPU), so it was refactored to properly include binding ranges for anything where the type of the field/variable implied a binding range should be created (even if the `LayoutResourceKind` was `::Uniform`).

* A few fixes were made to the CUDA implementation of `Renderer`, in order to get additional tests up and running. Most of these changes had to do with texture bindings, which hadn't really been tested previously.

In addition, a few changes were made that were attempts at getting more tests working, but didn't actually help. These could be dropped if requested:

* As a quality-of-life feature (not being used) the `object` style of `TEST_INPUT` line is upgraded to support inferring the type to use from the type of the input being set.

* Any `object` shader input lines get ignored in non-shader-object mode.</content>

<title>Remove support for explicit register/binding syntax on TEST_INPUT (#1132)</title>

<link rel='alternate' type='text/html' href='https://git.yummers.dev/slang.git/commit/?id=2ea64ff4f2c7c43b72ff24650330fca79a87500f'/>
<id>urn:sha1:2ea64ff4f2c7c43b72ff24650330fca79a87500f</id>
<content type='text'>
The `TEST_INPUT` facility allows textual Slang test cases to provide two kinds of information to the `render-test` tool:

1. Information on what shader inputs exist
2. Information on what values/objects to bind into those shader inputs

Under the first category of information, there exists supporting for attaching a `dxbinding(...)` annotation to a `TEST_INPUT` which seemingly indicates what HLSL `register` the input uses. There is a similar `glbinding(...)` annotation, used for OpenGL and Vulkan.

It turns out that these annotations were, in practice, completely ignored and had no bearing on how `render-test` allocates or bindings graphics API objects. There was some amount of code attempting to validate that explicit registers/bindings were being set appropriately, but the actual values were being ignored.

The visible consequence of the `dxbinding` and `glbinding` annotations being ignored is issue #1036: the order of `TEST_INPUT` lines was *de facto* determining the registers/bindings that were being used by `render-test`.

This change simply removes the placebo features and strips things down to what is implemented in practice: the `TEST_INPUT` lines do not need target-API-specific binding/register numbers, because their order in the file implicitly defines them.

I added logic to the parsing of `TEST_INPUT` lines to make sure I got an error message on any leftover annotations, and went ahead and systematicaly deleted all of the placebo annotations from our test cases.

If we decide to make `TEST_INPUT` lines *not* depend on order of declaration in the future, we can build it up as a new and better considered feature.

The main alternative I considered was to keep the annotations in place, and change `render-test` and the `gfx` abstraction layer to properly respect them, but that path actually creates much more opportunity for breakage (since every single test case would suddenly be specifying its root signature / pipeline layout via a different path using data that has never been tested). The approach in this change has the benefit of giving me high confidence that all the test cases continue to work just as they had before.</content>
