Subject: Add 'etags' makefile target.
X-Git-Url: http://git.megacz.com/?a=commitdiff_plain;h=e48d901d2e723c1b24b86c4755b948e70506f990;p=ghc-hetmet.git

Add 'etags' makefile target.

This only works with stage2 since `ghctags' is built against stage1
but not against the bootstrapping compiler.  Also note that all of GHC
must typecheck for this target to succeed.  Perhaps we should not
overwrite the old TAGS file by default then.
