[SPIR-V] /* multiple #lines overlapping */ in RenderDoc #7569
Description
Description
Since we've updated DXC to commit 50f53c6 (6 jun 2025), we are not able to debug our shaders in RenderDoc due to all source HLSL lines being duplicated (each HLSL line is present 13 times in the source file).
This doesn't occur when compiling the shaders using an older version of DXC (b26fd80, 8 oct 2024)
Steps to Reproduce
dxc.exe blit_hdr.hlsl.txt -E mainfragIGSpecific -T ps_6_0 -spirv -fspv-target-env=vulkan1.1 -Wall -Wno-unused-const-variable -D imBINDLESS=1 -fspv-extension=SPV_EXT_descriptor_indexing -fspv-extension=SPV_KHR_non_semantic_info -fspv-debug=vulkan-with-source
Actual Behavior
Environment
- DXC version dxcompiler.dll: 1.9 - 1.8.0.4946 (9efbb6c); dxil.dll: 1.4(10.0.18362.1)
