#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: new Priority: normal | Milestone: 8.6.1 Component: Runtime System | Version: 8.4.3 Keywords: | Operating System: MacOS X Architecture: Unknown/Multiple | Type of failure: None/Unknown Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ----------------------------------------+--------------------------------- for current master, if i build on a mac / OSX high sierra environment with CC set as any flavor of recent GCC rather than apple clang, i get a failure "no open frame" when as (aka apple clang / apple llvm acting as the assembler) is run on the .s file produced by stgRun.c (rts/StgCRun.c to be exact) this error message seems to come from https://github.com/llvm- mirror/llvm/blob/da4a2839d80ac52958be0129b871beedfe90136e/lib/MC/MCStreamer.cpp#L221 https://gist.github.com/cartazio/8cbfb3305e1daa4f7ffc3f6bb90a2891 has the gcc and clang style assembly for /usr/local/bin/gcc-8 -fno-stack-protector -DTABLES_NEXT_TO_CODE -Iincludes -Iincludes/dist -Iincludes/dist-derivedconstants/header -Iincludes/dist- ghcconstants/header -Irts -Irts/dist/build -Irts/dist/build -Irts/dist/build/./autogen -fno-common -U__PIC__ -D__PIC__ -x assembler -c /var/folders/py/wgp_hj9d2rl3cx48yym_ynj00000gn/T/ghc22029_0/ghc_1.s -o rts/dist/build/StgCRun.debug_o this is example asm for the the debug way -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15207 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
