Zalathar cd9021e8cb coverage: Discard spans that fill the entire function body 
When we try to extract coverage-relevant spans from MIR, sometimes we see MIR
statements/terminators whose spans cover the entire function body. Those spans
tend to be unhelpful for coverage purposes, because they often represent
compiler-inserted code, e.g. the implicit return value of `()`.

README.md

The tests in this directory are shared by two different test modes, and can be run in multiple different ways:

  • ./x.py test coverage-map (compiles to LLVM IR and checks coverage mappings)
  • ./x.py test coverage-run (runs a test binary and checks its coverage report)
  • ./x.py test coverage (runs both coverage-map and coverage-run)

Maintenance note

These tests can be sensitive to small changes in MIR spans or MIR control flow, especially in HIR-to-MIR lowering or MIR optimizations.

If you haven't touched the coverage code directly, and the tests still pass in coverage-run mode, then it should usually be OK to just re-bless the mappings as necessary with ./x.py test coverage-map --bless, without worrying too much about the exact changes.
