#3555: Vectorisation error with negative Double const
-----------------------------+----------------------------------------------
Reporter: ams | Owner:
Type: bug | Status: new
Priority: normal | Component: Data Parallel Haskell
Version: 6.10.4 | Severity: normal
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Negative Double constants cause an error in parallel comprehensions. This
function
negs xs = [: -1.0 | x <- xs :]
doesn't make it through the compiler; this
negs xs = [: (0.0 - 1.0) | x <- xs :]
does.
The error text is
*** Vectorisation error ***
Tycon not vectorised: GHC.Num.T:Num
