How do you execute the JALR instruction of riscv-32?

[qiluge]

The tracing code log the state of UNICORN executing result：

t=2022-08-24T16:44:57+0800 lvl=info GID=50 msg="registers: map[0:0 1:1000928 2:4294966816 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:4294966816 11:5 12:0 13:0 14:0 15:0 16:0 17:5 18:0 19:0 20:0 21:0 22:0 23:0 24:0 25:0 26:0 27:0 28:0 29:0 30:0 31:0 32:1070564]"

But in my program, the result is:

t=2022-08-24T16:03:22+0800 lvl=info GID=21 msg="registers: map[0:0 1:1000928 2:4294966816 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:4294966816 11:5 12:0 13:0 14:0 15:0 16:0 17:5 18:0 19:0 20:0 21:0 22:0 23:0 24:0 25:0 26:0 27:0 28:0 29:0 30:0 31:0 32:1070564]"
t=2022-08-24T16:03:22+0800 lvl=info GID=21 msg="executing instruction: 001055e4: 4dc080e7 \tjalr 1244(ra)"
t=2022-08-24T16:03:22+0800 lvl=info GID=21 msg="registers: map[0:0 1:1070568 2:4294966816 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:4294966816 11:5 12:0 13:0 14:0 15:0 16:0 17:5 18:0 19:0 20:0 21:0 22:0 23:0 24:0 25:0 26:0 27:0 28:0 29:0 30:0 31:0 32:1002172]"

There are too many difference between UNICORN and my program, not only the value of nextPC, but also others registers, such as x[1](RA) and x[2](SP).

note: register[0,31] are x[0,31], register[32] is pc

[qiluge]

should write 1070564+4 to rd, and nextPC should be 1000928 + 1244.

Hello, could you provide a small reproduction script? It's hard to infer anything from such logs.
