%description
QBE is a compiler backend that aims to provide 70% of the performance of
industrial optimizing compilers in 10% of the code. QBE fosters language
innovation by offering a compact user-friendly and performant backend. The size
limit constrains QBE to focus on the essential and prevents embarking on a
never-ending path of diminishing returns.
