gold is an ELF linker. It is intended to have complete support for
|
||
|
|
ELF and to run as fast as possible on modern systems.
|
||
|
|
|
||
|
|
It is written in C++. It is (intended to be) a GNU program, and
|
||
|
|
therefore follows the GNU formatting standards as modified for C++.

The linker is intended to have complete support for cross-compilation,
|
||
|
|
which still supporting the normal case of native linking as fast as
|
||
|
|
possible. This makes the code more complex.
|
||
|
|
|
||
|
|
Many functions are actually templates whose parameter is the ELF file
|
||
|
|
class (e.g., 32 bits or 64 bits). The code is the same, but we don't
|
||
|
|
want to pay the execution time cost of always using 64-bit integers if
|
||
|
|
the target is 32 bits.
