Package alignchecker provides routines to check Go and C struct alignments
func CheckStructAlignments ¶
CheckStructAlignments checks whether size and offsets match of the given C and Go structs which are listed in the given toCheck map (C struct name => Go struct reflect.Type).
C struct size info is extracted from the given ELF object file debug section encoded in DWARF.
To find a matching C struct field, a Go field has to be tagged with `align:"field_name_in_c_struct". In the case of unnamed union field, such union fields can be referred with special tags - `align:"$union0"`, `align:"$union1"`, etc.
