-nmagic
Turn off page alignment of sections, and mark the output as
-N
-omagic
Set the text and data sections to be readable and writable. Also, do not page-align the data seg-
ment, and disable linking against shared libraries. If the output format supports Unix style magic
numbers, mark the output as
-no-omagic
This option negates most of the effects of the

shared libraries. Use

-emit-relocs
Leave relocation sections and contents in fully linked exececutables. Post link analysis and op-
timization tools may need this information in order to perform correct modifications of executa-
bles. This results in larger executables.
This option is currently only supported on ELF platforms.
-r
-relocateable
Generate relocatable output--i.e., generate an output file that can in turn serve as input to
This is often called partial linking. As a side effect, in environments that support standard Unix
magic numbers, this option also sets the output file's magic number to

resolve references to constructors; to do that, use
When an input file does not have the same format as the output file, partial linking is only sup-
ported if that input file does not contain any relocations. Different output formats can have further
restrictions; for example some
