Hi Everyone, I'm working on a early LeMaker HiKey with GCC 4.9.2. I believe everything is fully patched.
I'm using the builtin's because the intrinsics are missing. I lifted it from https://gcc.gnu.org/ml/gcc-patches/2015-05/msg01976.html. Any ideas on this issue? hikey$ g++ -march=armv8-a test.cxx -c test.cxx: In function ‘poly128_t VMULL_P64(poly64_t, poly64_t)’: test.cxx:10:1: error: unrecognizable insn: } ^ (insn 9 8 12 2 (set (reg:TI 73 [ D.17869 ]) (unspec:TI [ (reg:DI 75) (reg:DI 76) ] UNSPEC_PMULL)) test.cxx:9 -1 (nil)) test.cxx:10:1: internal compiler error: in extract_insn, at recog.c:2202 Please submit a full bug report, Thanks in advance.
