#16258: PowerPC Big-Endian: ArithInt16, ArithInt8, ArithWord16, and ArithWord8 fail -------------------------------------+------------------------------------- Reporter: trommler | Owner: trommler Type: bug | Status: new Priority: normal | Milestone: 8.10.1 Component: Compiler | Version: 8.7 Resolution: | Keywords: Big-endian Operating System: Unknown/Multiple | Architecture: powerpc64 Type of failure: Incorrect result | Test Case: at runtime | primops/should_run/ArithInt16, | primops/should_run/ArithWord16, | primops/should_run/ArithWord8, | primops/should_run/ArithInt8 Blocked By: | Blocking: Related Tickets: #16222 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by trommler): In Cmm I find the following 16 bit store to the stack: {{{ R1 = _s1MY::P64; // CmmAssign I64[Sp] = stg_ap_n_info; // CmmStore I16[Sp + 8] = _s1N6::I16; // CmmStore call stg_ap_n_fast(R2, R1) args: 24, res: 8, upd: 8; // CmmCall }}} This is most likely wrong, it should probably be a 64 bit store. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16258#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
