Types ¶
type CachedFile ¶
CachedFile contains the content of a file split into lines.
type Disasm ¶
type Disasm struct {
// contains filtered or unexported fields
}
Disasm is a disassembler for a given File.
func (*Disasm) Decode ¶
func (d *Disasm) Decode(start, end uint64, relocs []Reloc, f func(pc, size uint64, file string, line int, text string))
Decode disassembles the text segment range [start, end), calling f for each instruction.
func (*Disasm) Print ¶
Print prints a disassembly of the file to w. If filter is non-nil, the disassembly only includes functions with names matching filter. If printCode is true, the disassembly includs corresponding source lines. The disassembly only includes functions that overlap the range [start, end).
type File ¶
type File struct {
// contains filtered or unexported fields
}
A File is an opened executable file.
func Open ¶
Open opens the named file. The caller must call f.Close when the file is no longer needed.
func (*File) DWARF ¶
DWARF returns DWARF debug data for the file, if any. This is for cmd/pprof to locate cgo functions.
func (*File) LoadAddress ¶
LoadAddress returns the expected load address of the file. This differs from the actual load address for a position-independent executable.
func (*File) PCLineTable ¶
type FileCache ¶
type FileCache struct {
// contains filtered or unexported fields
}
FileCache is a simple LRU cache of file contents.
func NewFileCache ¶
NewFileCache returns a FileCache which can contain up to maxLen cached file contents.
type Reloc ¶
type Reloc struct { Addr uint64 // Address of first byte that reloc applies to. Size uint64 // Number of bytes Stringer RelocStringer }
