Functions ¶
func AddCovMeta ¶
func AddCovMeta(p unsafe.Pointer, dlen uint32, hash [16]byte, pkpath string, pkgid int, cmode uint8, cgran uint8) uint32
AddCovMeta 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.
func AppendCovCounterList ¶
func AppendCovCounterList(res []CovCounterBlob)
func GetCovPkgMap ¶
Types ¶
type CovCounterBlob ¶
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.
type CovMetaBlob ¶
type CovMetaBlob struct {
P *byte
Len uint32
Hash [16]byte
PkgPath string
PkgID int
CounterMode uint8 // coverage.CounterMode
CounterGranularity uint8 // coverage.CounterGranularity
}
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.
func GetCovMetaList ¶
func GetCovMetaList() []CovMetaBlob
