Bug ID: 106504
Summary: vulkan SPIR-V parsing failed at
../src/compiler/spirv/vtn_cfg.c:381
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Vulkan/Common

hello,
I get an error with both radv and intel
SPIR-V parsing FAILED:
In file ../src/compiler/spirv/vtn_cfg.c:381
block->node.link.next == NULL
0 bytes into the SPIR-V binary
when using this hlsl shader (compiled with glslang):
float4 main(float4 fragCoord : SV_POSITION) : SV_Target0
{
float4 Sum = 0;
for (int i=0; i<2; i++) {
for (int j=0; j<2; j++) {
Sum += fragCoord;
}
}
return Sum / 4;
}
(the spirv source file is attached.)
This report is a follow-up to
https://github.com/KhronosGroup/SPIRV-Tools/issues/1456
"The outer loop's continue block ends up as the same block as the inner loop's
continue block. I wonder if the Mesa compiler doesn't expect this (assuming
there are no other bugs)."
