| HEAD | 1b3887f | Fix __init() functions that returns an existing value (#3866) Fixes the issue #3671 * The __init constructors are not expected to return a value like other member functions, but must construct a new value and return the struct type or none. * This patch enables this behavior in the IR lowering without complaining about illegal situations where the user returns an invalid type or none at all. Translate ordinary struct `return ...;` to `this = ...; return this;` Translate NonCopyableType struct `return ...;` to `return this;` * This patch also fixes the issue with type checking when __init() returns a void that mismatches the base type of the struct/ class Translate ordinary struct `return;` to `return this;` Translate NonCopyableType struct `return;` to `return;` * Add end-to-end test and compile only tests to check the above behavior. | 05 April 2024, 23:47:47 UTC |

| refs/tags/'' | b1317cd | Yet more definitions moved into the stdlib (#1263) The only big catch that I ran into with this batch was that I found the `float.getPi()` function was being emitted to the output GLSL even when that function wasn't being used. This seems to have been a latent problem in the earlier PR, but was only surfaced in the tests once a Slang->GLSL test started using another intrinsic that led to the `float : __BuiltinFloatingPointType` witness table being live in the IR. The fix for the gotcha here was to add a late IR pass that basically empties out all witness tables in the IR, so that functions that are only referenced by witness tables can then be removed as dead code. This pass is something we should *not* apply if/when we start supporting real dynamic dispatch through witness tables, but that is a problem to be solved on another day. The remaining tricky pieces of this change were: * Needed to remember to mark functions as target intrinsics on HLSL and/or GLSL as appropriate (hopefully I caught all the cases) so they don't get emitted as source there. * The `msad4` function in HLSL is very poorly documented, so filling in its definition was tricky. I made my best effort based on how it is described on MSDN, but it is likely that if anybody wants to rely on this function they will need us to vet our results with some tests. | 09 March 2020, 16:02:36 UTC |

| refs/tags/v0.13.6 | 15b46af | If a locator is not set for a DownstreamCompiler type, that doesn't *necessarily* mean that there isn't one, for example with the GENERIC_C_CPP option. This could also be fixed by say giving this type an empty locator, or special casing. The option chosen here, is to allow lookup even if there isn't a locator. Note that there is some special case handling, where a generic lookup, will prime all of the specific types. (#1154) | 16 December 2019, 16:19:37 UTC |

| refs/tags/v0.8.8 | 88023ae | Reflection: allow querying of semantics on varying input/output (#224) This is functionality required to support a Falcor bug fix. Most of the code to compute the right semantic name/index for a parameter was already present. This change adds: - Storage for semantic name/index on every `VarLayout` - Note: this is wasteful and should be optimized later - A public API to query the semantic name/index - The contract is that this API returns `NULL` if the parameter had no semantic - A bit of work in `parameter-binding.cpp` to attach semantics to varying input/output when traversing varying parameters. - Note: this is intentionally set up so that it associates semantics even with non-leaf parameters, so that an API user can query the semantic of a `struct` parameter and know that its members will be assigned sequential semantic indices from its starting value. - Support for dumping this information in reflection tests One notable thing that I did *not* change here is that the reflection test fixture doesn't report information on the output of an entry point, even though it really should. That should be fixed in a separate change, though, because it would affect many of the expected outputs. | 19 October 2017, 18:49:16 UTC |
