gold is a new, optimised, multi-threaded linker with support
|
|
for plugins. Designed to be a drop-in replacement for the

original linker, ld, it can be much faster, with a 5:1 or
|
|
bigger ratio being not uncommon, YMMV.

Add an ld wrapper that calls to either gold or ld.

By default, the wrapper will call to the default wrapper,

but if you set the environment variable CTNG_LD_IS, you
|
|
can change which linker will get called:
|
|
CTNG_LD_IS=gold will unconditionally call the gold linker

CTNG_LD_IS=bfd will unconditionally call the old bfd ld linker

binutils can be extended through the use of plugins.

Especially, gold can use the lto-plugin, as installed

by gcc, to handle LTO.
