Package-Level Type Names (total 2)

	/* sort by: alphabet | popularity */
	 type CovCounterBlob (struct)
		CovCounterBlob is a container for encapsulating a counter section
		(BSS variable) for an instrumented Go module. Here "counters"
		points to the counter payload and "len" is the number of uint32
		entries in the section.

		Fields (total 2)
			Counters *uint32
			Len uint64

	 type CovMetaBlob (struct)
		CovMetaBlob is a container for holding the meta-data symbol (an
		RODATA variable) for an instrumented Go package. Here "p" points to
		the symbol itself, "len" is the length of the sym in bytes, and
		"hash" is an md5sum for the sym computed by the compiler. When
		the init function for a coverage-instrumented package executes, it
		will make a call into the runtime which will create a covMetaBlob
		object for the package and chain it onto a global list.

		Fields (total 7)
			CounterGranularity uint8
				// coverage.CounterGranularity

			CounterMode uint8
				// coverage.CounterMode

			Hash [16]byte
			Len uint32
			P *byte
			PkgID int
			PkgPath string


Package-Level Functions (only one)

	 func AddMeta(p unsafe.Pointer, dlen uint32, hash [16]byte, pkgpath string, pkgid int, cmode uint8, cgran uint8) uint32
		AddMeta is invoked during package "init" functions by the
		compiler when compiling for coverage instrumentation; here 'p' is a
		meta-data blob of length 'dlen' for the package in question, 'hash'
		is a compiler-computed md5.sum for the blob, 'pkpath' is the
		package path, 'pkid' is the hard-coded ID that the compiler is
		using for the package (or -1 if the compiler doesn't think a
		hard-coded ID is needed), and 'cmode'/'cgran' are the coverage
		counter mode and granularity requested by the user. Return value is
		the ID for the package for use by the package code itself,
		or 0 for impossible errors.


Package-Level Variables (only one)

	  var Meta struct{List []CovMetaBlob; PkgMap map[int]int; hardCodedListNeedsUpdating bool}
		Meta is the top-level container for bits of state related to
		code coverage meta-data in the runtime.
