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)."
