GHC的-c和-no-link选项有什么区别？

Question

The help says:

 -c  Do not link

and

 -no-link  Omit linking

I understand that -c prevents the linking part completely. But what's the difference if I specify -no-link ? Does the linking phase actually do something apart from linking?

Update: Interestingly, -no-link is deprecated in GHC 6.12, but undeprecated in GHC 7 .

Answer 1

AFAK -c doesn't handle dependencies. Eg

Main.hs:

module Main
where

import Test

main :: IO ()
main = test

Test.hs:

module Test
where

test :: IO ()
test = print 123

Trying to compile with -c :

$ ghc -c Main.hs

Main.hs:5:1:
    Failed to load interface for `Test'
    Use -v to see a list of the files searched for.

With -no-link :

$ ghc -no-link Main.hs
