Hello,
I’m trying to setup gem5 with RISC-V, the example hello binary in ./test folder
works fine on both scenario but
A) On Ubuntu (both 17.04 and 14.04), whatever binary (compiled with
riscv64-unknown-elf-gcc) I supply, I would get the error:
> Traceback (most recent call last):

B) On macOS (10.13), simple programs work fine (e.g. empty main function), but
when I run hello binary (compiled with riscv64-unknown-elf-gcc), I would get:
panic: Unknown instruction 0x00000000 at pc 0x0000000000012a28
Here’s a snippet of the end of the Exec trace:
@__swsetup_r+116 : jalr zero, ra, 0 : IntAlu :
D=0x0000000000013ebc
@__sfvwrite_r+272 : unknown opcode 0x00 : No_OpClass :
pc value appears to be correct, and according to the assembly file I dumped
from the hello binary, the instruction at offset 12a28 is valid (0xfff00793 li
a5, -1) instead of 0x00000000.
The problem seems to be somewhat similar to that in this thread
http://www.mail-archive.com/[email protected]/msg21438.html
<http://www.mail-archive.com/[email protected]/msg21438.html>, but no solution
was offered.
I would appreciate any help regarding either problem.
Thanks,
Jason
