#2991: .mix files generation broken with -fhpc and --make flags with lhs modules
-----------------------------+----------------------------------------------
Reporter: ppavel | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.10.1 | Severity: normal
Keywords: hpc make lhs | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
assume the project consisting of two files: !Main.lhs and !MyModule.hs.
Main.lhs imports !MyModule via standard import. Build the project with
ghc --make -fhpc -o main Main.lhs
The generated .mix file contains relevant information and hpc markup
correctly shows the coverage for !MyModule.
Now rename !MyModule.hs to !MyModule.lhs and enclose the code there in
\begin{code} / \end{code}. Build again. The compilation still succeeds and
the executable works fine. But !MyModule.mix now seems wrong and no hpc
coverage information is available for !MyModule
