Did you write that instruction by hand (in the original situation where it
crashed, not in this test case) ? I ask because I have never seen gcc nor
LLVM/Clang generate a memory address like that.
In VEX/priv/guest_arm64_toIR.c, function gen_indexed_EA, find this
case BITS4(1,1,1,1): goto fail; //ATC
case BITS4(0,1,1,1):
rhs = binop(Iop_Shl64, getIReg64orZR(mm), mkU8(szLg2));
vex_sprintf(buf, "[%s, %s lsl %u]",
nameIReg64orZR(nn), nameIReg64orZR(mm), szLg2);
break;
and remove the "goto fail;" on the first line, allowing it to fall through
to the 0111 case. Does that help? Does it provide the correct behaviour
for you for both positive and negative values of X0 ?
