Functions

func MakePosixMmap 

func MakePosixMmap(target *prog.Target, exec, contain bool) func() []*prog.Call

MakePosixMmap creates a "normal" posix mmap call that maps the target data range. If exec is set, the mapping is mapped as PROT_EXEC. If contain is set, the mapping is surrounded by PROT_NONE pages. These flags should be in sync with what executor.

func MakeSyzMmap 

func MakeSyzMmap(target *prog.Target) func() []*prog.Call
