#11395: The via-C code generation backend is incompatible with gcc 5.3.1 on m68k (ELF) --------------------------------------------+------------------------------ Reporter: mkarcher | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Linux | Architecture: m68k Type of failure: GHC doesn't work at all | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | --------------------------------------------+------------------------------ Comment (by slyfox): One more note: The bug you describe should surface on amd64 if you change return type from 'int' (%rax) to 'double' (%xmm0) in your example, correct? On gcc-5.3.0/amd64 it seems to work as expected: {{{ call double_returning_function cvttsd2si %xmm0, %eax cmpl $42, %eax }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11395#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
