 Hi Luka, I don't have access to and AArch64 machine unfortunately.I'm adding John Brawn who implemented experimental support for AArch64. On Fri, Sep 21, 2018 at 4:17 PM, Luka Ercegovcevic <Luka.Ercegovcevic at rt-rk.com> wrote: Hi everyone,

I can't find for which opcode llvm-exegesis works on AArch64. I have used bash script from the official site that testing all opcodes for X86 architecture and I changed script to test AArch64 opcodes and there is no working case.
There are some errors: 
Assertion for AArch64CallLowering::lowerReturn, 
setRegTo is not implemented, results will be unreliable, 
Infeasible : has unknown operands, 
Infeasible : Didn't find any scheme to make the instruction serial, 
Unsupported opcode: isPseudo. 
Unsupported opcode: isBranch/isIndirectBranch
Unsupported opcode: isCall/isReturn

I'm using llvm trunk (native build for AARCH64), am I missing something?  

Thanks!
