From 8753796aaca097153af3ccebdd0f17d80d25bb9f Mon Sep 17 00:00:00 2001 From: James Price Date: Tue, 6 Dec 2022 18:32:19 +0000 Subject: [PATCH] tint: Add PreservePadding transform This is used to ensure that assignments to host-visible memory do not modify padding bytes in structures and arrays. We decompose assignments of whole structure and array types into member-wise or element-wise copies, using helper functions. This is used in all backends except HLSL, which already decomposes memory accesses.
