| | 133 | == Warnings == |
| | 134 | |
| | 135 | We are aiming to make the GHC code warning-free for all warnings turned on by |
| | 136 | {{{ |
| | 137 | -Wall -fno-warn-name-shadowing |
| | 138 | }}} |
| | 139 | and as such the build sets these flags for the stage 2 compiler, and the validate script, which is used to test the build before commiting, additionally sets the `-Werror` flag. As the `-Werror` flag is not set during normal builds, during development warnings will be printed but won't halt the build. |
| | 140 | |
| | 141 | Currently we are some way from our goal, so many modules have a |
| | 142 | {{{ |
| | 143 | {-# OPTIONS_GHC -w #-} |
| | 144 | }}} |
| | 145 | pragma; you are encouraged to remove this pragma and fix any warnings when working on a module. |
