#13378: ghc-stage2 broken for quick-llvm -------------------------------------+------------------------------------- Reporter: angerman | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Building GHC | (amd64) failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): Okay so `checkClosureShallow` is getting passed the address of `base_GHCziConcziIO_ensureIOManagerIsRunning_closure`, which is all well and good. Running the disassembly of the closure back through an assembler gives {{{ Contents of section .text: 0000 20c89b02 01000000 00000000 00000000 ............... }}} which also looks fine (a pointer to some code, followed by a zero or unused word). Based on the definition of `LOOKS_LIKE_CLOSURE_PTR`, it appears that the info table that is supposed to be located before whatever symbol is at `0x01029bc820` is missing; probably a dead code stripping issue again? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13378#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
