#10383: AArch64: get GHC Calling convention working ----------------------------------------+---------------------------------- Reporter: erikd | Owner: erikd Type: feature request | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: aarch64 Type of failure: Building GHC failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: ----------------------------------------+---------------------------------- Comment (by erikd): I am reasonably certain that this is the same problem as #10375. Running: {{{ inplace/bin/ghc-stage2 +RTS -Ds -Di -Dw -DG -Dg -Db -DS -Dt -Dp -Da -Dl -Dm \ -Dc -Dr }}} otherwise know as "all the damn debug flags I can find" results in: {{{ stg_ap_v_ret... FUN/1(0x7f99ceba88, 0x7f98f041b9, 0x7f98f05448, 0x7f98f084c8, 0x7f98f084d8, 0x7f993cb861, 0x7f98f08558, (nil)d#, (nil)d#, 0x1fd#, 0x4d#, 0x5d#, 0x6d#) stg_ap_0_ret... base:GHC.Event.Manager.Created() 7f98eff1f0: cap 0: thread 2 stopped (yielding) 7f98eff1f0: giving up capability 0 7f98eff1f0: passing capability 0 to bound task 0x7f990ff000 7f990ff000: woken up on capability 0 7f990ff000: resuming capability 0 7f990ff000: cap 0: running thread 1 (ThreadRunGHC) Segmentation fault }}} which just like trac #10375 is GHC crashing in the `schedule` function of `rts/Schedule.c` with `what_next == ThreadRunGHC`. Will keep this open just in case its not. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10383#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
