RFC: Should the linker support '--fast' and if so, what should it do ?

[Nick Clifton]

Hi Guys,

   Attached is a proposed patch to implement "-O 0" as a command line option
   that disables merging.

   The patch does change the linker's default behaviour, albeit in a small way:
   It changes the linker's nominal default optimization level to 1 instead of 0,
   so that in order to gain the enable-heavy-optimization effect you need to link
   with "0O 2" (or higher) whereas before "-O 1" would have also done this.  (With
   the patch applied "-O 1" now restores the linker's default behaviour of neither
   optimizing nor skipping the merge stage).

   Thoughts ?

Cheers
   Nick
