# Note to users of hardened gcc-3.x:

#
|

|
|
# If you emerge ghc-bin with hardened gcc it should work fine (because
|
| 8 |
|
|
# we turn off the hardened features that would otherwise break ghc).
|
| 9 |
|
|
# However, emerging ghc-bin while using a vanilla gcc and then switching
|
| 10 |
|
|
# to hardened gcc (using gcc-config) will leave you with a broken ghc. To
|
| 11 |
|
|
# fix it you would need to either switch back to vanilla gcc or re-emerge
|
| 12 |
|
|
# ghc-bin (or ghc). Note that also if you are using hardened gcc-3.x and
|
| 13 |
|
|
# you switch to gcc-4.x that this will also break ghc and you'll need to
|
| 14 |
|
|
# re-emerge ghc-bin (or ghc). People using vanilla gcc can switch between
|
| 15 |
|
|
# gcc-3.x and 4.x with no problems.
