regexp/syntax — validation proof

Go’s own regexp/syntax test suite, converted to C# by go2cs, built against the converted standard library, run under the Go-semantics test host, and compared verdict for verdict against a clean go test -json baseline of the same sources. This page is generated by the converter from that comparison — it is the evidence behind the regexp/syntax row in Validated Test Packages.

Excluded declarations

Declarations filtered from both sides of the comparison, and therefore not claimed above: Benchmark, Fuzz and Example declarations the converted host does not execute, plus any test requiring a capability the managed runtime does not provide — a testing member the host has not implemented, or a platform behavior it provably cannot reproduce. Each is named with the capability it needs.
