|#29||invalid||Check for exhaustive patterns is broken||nobody|
When some of the patterns in a function definition or case expression contain guards, the compiler gives false warnings about non-exhaustive pattern matches. A pity, because this kind of warning is very useful indeed! For example, I get >ghc --make -Wall See.hs ghc-5.02.1: chasing modules from: See.hs Compiling See ( See.hs, ./See.o ) See.hs:17: Warning: Pattern match(es) are non-exhaustive In the definition of `insert': Patterns not matched: _ _ (TREE _ _ _ _) See.hs:41: Warning: Pattern match(es) are non-exhaustive In a case alternative EMPTY: Patterns not matched: TREE _ _ _ _ for the attached file. [I am not sure filling in the e-mail address box had any effect on the last two complaints I submitted, so I repeat my address here: firstname.lastname@example.org]
|#68||wontfix||Warnings for unitialized fields||nobody|
Would it be possible to add flag to disable warnings for unitialized fields just when using constructor with zero fields? I mean, if I use
to construct empty record, it is a bit unpleasant that I get flooded by dozens of useless warnings; but I don't want to disable them -- they are useful when I forget to initialize some field(s).
|#106||duplicate||com. line args not honoured for recompil||nobody|
I compiled a file with a standard compile and link and some flags, include -fallow-overlapping-isntances. I was interested in whether overlapping instances were really required, so I recompiled -- without modifying the file -- without -fallow-overlapping-instances. I got the "compilation IS NOT required" message, clearly erroneous.
Suggestion: flag configuration / compiler state stored in generated code and checked on recompile.
