Slow link time   
When using gcc 3.3.5 link time is 1.43sec, executable is 12Meg ( debug version ) and map file is 800k

When using gcc 4.2.1 + bin utils 2.17 link time is *10 sec*,executable is 8.5Meg and map file is 2.5M.

It's the time difference that worries me ;-)

Is this a single invocation of the linker? Which host/target is this for? Can you provide a test case?

I ran this test multiple time, erasing the executable only,

QNX6 self host

Challenging but I'll see what I can do.

Re: Slow link time   
Can you try the attached 2.18 x86 linker to see if there is any difference in performance?
