-// Note that the MIR with injected coverage intrinsics includes references to source locations,
-// including the source file absolute path. Typically, MIR pretty print output with file
-// references are safe because the file prefixes are substituted with `$DIR`, but in this case
-// the file references are encoded as function arguments, with an `Operand` type representation
-// (`Slice` `Allocation` interned byte array) that cannot be normalized by simple substitution.
-//
-// The first workaround is to use the `SourceMap`-supported `--remap-path-prefix` option; however,
-// the implementation of the `--remap-path-prefix` option currently joins the new prefix and the
-// remaining source path with an OS-specific path separator (`\` on Windows). This difference still
-// shows up in the byte array representation of the path, causing Windows tests to fail to match
-// blessed results baselined with a `/` path separator.
-//
-// Since this `mir-opt` test does not have any significant platform dependencies, other than the
-// path separator differences, the final workaround is to disable testing on Windows.
