#11784: panic "hscCmmFile: no_mod" with `-v2 and above -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): The problem here is that `hscCompileCmmFile` needs a `Module` to give to `CodeOutput.codeOutput`. The downstream uses of this `Module` are, * `outputForeignStubs`: needs a string to form the stem of the stub filename * `PIC.howToAccessLabel`: calls `CLabel.labelDynamic`, which, * then wants to compare it against another `Module` taken from a `HpcTicksLabel` * and uses it to call `Packages.isDllName` Given that `PIC.howToAccessLabel` hasn't blowing up due to the bottoming `Module`s we give it for C-- files, I suppose it should be safe for `hscCompileCmmFile` to simply make up a module name to give to the backend. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11784#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
