--- Comment #1 from quequotion at mailinator dot com ---
The manpage for ld says:

-O level
    If level is a numeric values greater than zero ld optimizes the output.
This might take significantly longer and therefore probably should only be
enabled for the final binary. At the moment this option only affects ELF shared
library generation. Future releases of the linker may make more use of this
option. Also currently there is no difference in the linker's behaviour for
different non-zero values of this option. Again this may change with future
releases. 

Is the same true for ld.gold? In which case -O, -Os, -Og, -Ofast are not
implemented and -O1 = -O2 = -O3 = -O4 and so on?
