Functions ¶

func Load ¶

func Load(l *loader.Loader, arch *sys.Arch, localSymVersion int, f *bio.Reader, pkg string, length int64, pn string, initEhdrFlags uint32) (textp []loader.Sym, ehdrFlags uint32, err error)

Load loads the ELF file pn from f. Symbols are installed into the loader, and a slice of the text symbols is returned.

On ARM systems, Load will attempt to determine what ELF header flags to emit by scanning the attributes in the ELF file being loaded. The parameter initEhdrFlags contains the current header flags for the output object, and the returned ehdrFlags contains what this Load function computes. TODO: find a better place for this logic.
