Documentation
readElfSectionByName :: DynFlags -> ByteString -> String -> IO (Maybe ByteString) Source #
Given a section name, read its contents as a ByteString.
If the section isn't found or if there is any parsing error, we return Nothing
readElfNoteAsString :: DynFlags -> FilePath -> String -> String -> IO (Maybe String) Source #
read a Note as a String
If you try to read a note from a section which does not support the Note format, the parsing is likely to fail and Nothing will be returned
makeElfNote :: String -> String -> Word32 -> String -> SDoc Source #
Generate the GAS code to create a Note section
Header fields for notes are 32-bit long (see Note [ELF specification]).
It seems there is no easy way to force GNU AS to generate a 32-bit word in every case. Hence we use .int directive to create them: however "The byte order and bit size of the number depends on what kind of target the assembly is for." (https:/sourceware.orgbinutilsdocsas/Int.html#Int)
If we add new target platforms, we need to check that the generated words are 32-bit long, otherwise we need to use platform specific directives to force 32-bit .int in asWord32.
