#12054: PowerPC: Unsupported relocation against x0 ----------------------------------------+-------------------------------- Reporter: erikd | Owner: trommler Type: bug | Status: new Priority: normal | Milestone: 8.0.2 Component: Compiler (CodeGen) | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: powerpc Type of failure: Building GHC failed | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | ----------------------------------------+-------------------------------- Comment (by trommler): I could not reproduce the bug on powerpc64le which is strange. The above code is generated when we need to move the stack pointer further than what fits into a 16 bit signed offset. The stack pointer is updated when we allocate a new stack frame or when we need to allocate additional spill slots in the current stack frame. A spill slot on 64-bit, however, has eight bytes not four so I would expect to see the issue on powerpc64le and powerpc64 too. The bug in the pretty printer affects all PowerPCs but it seems I can't tickle it on 64-bit processors. Is there another bug higher up in the code generator that affects only 32 bit? How can we produce a regression test for this bug? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12054#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
