From 4093fe49bfcd201a4f62b02c73b81bfcf5055e99 Mon Sep 17 00:00:00 2001 From: Henri Verbeet Date: Wed, 22 Jun 2022 16:09:01 +0200 Subject: [PATCH] vkd3d-compiler: Default to VKD3D_SHADER_SOURCE_HLSL when the source size is smaller than a uint32_t. For example, when the input is an empty file. Leaving the source type as VKD3D_SHADER_SOURCE_NONE would cause (potential) subsequent get_source_type_info() calls to return NULL, resulting in a segmentation fault.
