+title: 2026-03-12 - HLSL Working Group Minutes
+---
+
+* Discussion topics
+  * @s-perron mentioned that [llvm/offload-test-suite#756] has been merged,
+    adding depth texture support for the test suite for SPIR-V.
+  * @icohedron mentioned [llvm/wg-hlsl#394], a proposal to move HLSL library
+    function definitions into tablegen, rather than implementing the header
+    entirely by hand.
+  * @farzonl pointed out that we're getting quite a few PRs from folks outside
+    of the meeting, and reminded people to watch for these so that they get
+    good and prompt reviews.
+  * @bogner pointed out that the vector elementwise-alignment datalayout
+    specifier is now available as of [llvm/llvm-project#180617]. He's
+    implementing this for DirectX but would like help for the SPIR-V side.
+  * @s-perron about the status around [llvm/llvm-project#183367]. @bogner
+    pointed out that we'd like to be consistent between DirectX and SPIR-V here
+    if possible, but if not we should follow @s-perron's suggestion to convert
+    the "unbounded" value when processing the intrinsic itself for SPIR-V.
+  * @s-perron reminded everyone that when writing Vulkan specific tests, the
+    flags to `spirv-val` need to be set appropriately so that it doesn't run
+    its validation under the wrong environment.
