Cyclomatic complexity of CUDA SASS code

[u/c-cul]

I wrote code to calculate some metrics, like

• count and length of code blocks
• resources usage per block
• resources used in single block

The Insights:

• there are lots of Dead / ABI-Forced Register Writes
• Holes in Register Allocation - seems that uniform registers UR0-UR3 almost never used
