#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: 8.8.1 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 carter): i did two different threaded runs, thres a clean HUGE difference on clang vs gcc, favoring gcc in the GC timings, the one program where this is strongly not the case is k nucleo tide, I'll attach these two sets of nofib runs here. nofib report i name "dirty" is merely "i didn't clean and rebuild right before running nofib". so its likely to be cleaner measurements if thermal throttling were an issue (i used the intel power gadget during the first run, and I idn't see a difference in peak average frequency between the two, at least when eyeballing it) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15207#comment:30 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
