#15207: bad dwarf frame in stgRun.c when compiled with with gcc on mac and assembled by as/gcc/clang (aka apple clang assembler) -------------------------------------+------------------------------------- Reporter: carter | Owner: (none) Type: bug | Status: infoneeded Priority: normal | Milestone: 8.6.1 Component: Runtime System | Version: 8.4.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4781 Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Sigh; this is all just very unfortunate. It seems that there is something funny about Apple's clang (surprise surprise!) The patch as-merged breaks under standard Clang, which apparently inserts the necessary CFI directives into inline assembler, just as GCC does. I'm going to revert until we have a better understanding of what is going on here. Carter, can you look into precisely when this happens? Specifically which Clang version are you seeing break? Which Clang versions work? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15207#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
