Panic when compiling cmm file together with -outputdir
To reproduce:
$ touch test.cmm
$ ghc -c test.cmm -outputdir=build
ghc-stage2: panic! (the 'impossible' happened)
(GHC version 7.9.20140428 for x86_64-unknown-linux):
hscCmmFile: no_mod
The panic is declared in main/HscMain.hs:hscCompileCmmFile
in place of current module name, but forced in main/CodeOutput.lhs:outputForeignStubs
by doesFileExist
.
It works without -outputdir
because in that case module name is not used to create path to stub file, see main/Finder.lhs:mkStubPaths
.
