gold – The GNU ELF linker

In software engineering, gold is a linker for ELF files. It became an official GNU package and
was added to binutils in March 2008[1] [2] and first released in binutils version 2.19. gold
was developed by Ian Lance Taylor and a small team at Google.[3] The motivation for writing
gold was to make a linker that is faster than the GNU linker,[3] especially for large
applications coded in C++. 

[bash]
$gcc -fuse-ld=gold hello.c
$./a.out
hello world
$./a.out
hello world
$./a.out
hello world
$./a.out
hello world
$time ./a.out
hello world

real 0m0.002s
user 0m0.002s
sys 0m0.001s
$gcc hello.c
$time ./a.out
hello world

real 0m0.002s
user 0m0.000s
sys 0m0.002s
$gcc -fuse-ld=gol hello.c
gcc: error: unrecognized command line option ‘-fuse-ld=gol’; did you mean ‘-fuse-ld=gold’?
