#8951: genSym uses atomic_inc but doesn't link arm_atomic_spin_lock -------------------------------------+------------------------------------- Reporter: cjwatson | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.4 Component: Build | Version: 7.8.1-rc1 System | Keywords: Resolution: | Architecture: arm Operating System: Linux | Difficulty: Unknown Type of failure: Building | Blocked By: GHC failed | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by bgamari): Hmm, so the symbols in question are defined in `rts/OldARMAtomic.c`. These are necessary as this build occurred on an ARMv5 box. It appears `OldARMAtomic.o` is being compiled into `libRTS` so this raises the question of why it's not being found by the linker. nomeata, however, is doing his builds on ARMv7 hardware. In light of this it's likely that there are two bugs here: 1. nomeata's build is using the pre-ARMv6 fallbacks unnecessarily 2. the pre-ARMv6 fallbacks aren't compiled/linked properly -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8951#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
