[LLVMdev] ARM issue: Trying to add an operand to a machine instr that is already done!
Hello, I've compiled today's LLVM on ARM/Linux machine and attempted to use our GHC/ARM port (which is using LLVM as a backend for generating machine code) with it but I've failed in compiling GHC alone as LLVM fails on me with following message: llc: /export/home/karel/vcs/llvm-ghc-arm/lib/CodeGen/MachineInstr.cpp:612: void llvm::MachineInstr::addOperand(const llvm::MachineOperand&): Assertion `(isImpReg || !OperandsComplete()) && "Trying to add an operand to a machine instr that is already done!"' failed. Stack dump: 0. Program arguments: llc -O3 -relocation-model=static /tmp/ghc12607_0/ghc12607_0.bc -o /tmp/ghc12607_0/ghc12607_0.lm_s -mattr=+v7,+vfp3 1. Running pass 'Function Pass Manager' on module '/tmp/ghc12607_0/ghc12607_0.bc'. 2. Running pass 'ARM load / store optimization pass' on function '@s51E_info' Aborted FYI: Stephen Blackheath enhanced LLVM to support custom GHC calling convention on ARM and I've added support for floating point regs to his patch. Current version is attached for your reference. I'm writing this since GHC/ARM is working well with LLVM from 2011-07-12 with this patch applied but it's not working with today's LLVM. I'm curious if this failure is caused by our patch (or some omission in it) or if this is issue in LLVM itself. Thanks for any idea where to start looking to fix that!

Hi Karel, Mind trying again with current top of tree? Owen's fixed a few things today that were manifesting with that error. -Jim On Aug 29, 2011, at 2:33 PM, Karel Gardas wrote:> Hello, > > I've compiled today's LLVM on ARM/Linux machine and attempted to use our GHC/ARM port (which is using LLVM as a backend for generating machine code) with it but I've failed in compiling GHC alone as LLVM fails on me with following message: > > llc: /export/home/karel/vcs/llvm-ghc-arm/lib/CodeGen/MachineInstr.cpp:612: void llvm::MachineInstr::addOperand(const llvm::MachineOperand&): Assertion `(isImpReg || !OperandsComplete()) && "Trying to add an operand to a machine instr that is already done!"' failed. > Stack dump: > 0.

Hi Jim and Eric! thanks a lot for your fantastically fast reply. I'm going to update and will report tomorrow when all the building is done. Thanks!
