[gvnsink] evaluate impact of gvnsink optimization #94832

Open hiraditya opened 4 weeks ago

hiraditya commented 4 weeks ago

Following up from https://discourse.llvm.org/t/rfc-what-are-the-blockers-to-turning-on-gvnsink-by-default/72326. Before asking for review we should measure the impact of this optimization at various opt levels (-O2, -O3, -Os, -Oz)
