package coverage

// This package contains support routines for coverage "fixup" in the
// compiler, which happens when compiling a package whose source code
// has been run through "cmd/cover" to add instrumentation. The two
// important entry points are FixupVars (called prior to package init
// generation) and FixupInit (called following package init
// generation).

Open a web browser displaying annotated source code:
