addi opcode wrong result
MaximMndv opened this issue · comments
Tried to run GCC C compiled code on SERV RISC V.
Seems the addi opcode behaviour is wrong.
assembly code like:
addi sp,sp,-64
or
deadc1b7 lui gp,0xdeadc
eef18193 addi gp,gp,-273 # 0xdeadbeef
result in wrong value in the target register.
Same code on PicoRV32 and on DarkRISCV works fine.
Ouch. That sounds really bad. I can't reproduce this issue here and haven't seen any problems when running the RISC-V compliance test suite. Would it be possible to send me a VCD trace, simulator logs or something like that? Really want to get this fixed soon if it's an issue.
What simulator are you using? Or is it a synthesis issue?
Hi Olof
I use Active HDL Lattice edition that comes with Lattice Diamond EDA for MachXO3 FPGAs.
I'll see if I can generate VCD trace files for you.

Hi Olof
As requested the VCD attached with disassembly of the code.
Check the SP is initialized to 7FC.
The GP register seems to get wrong value: BD5B7EEF and not DEADBEEF as expected.
Then GP is not copied correctly to TP
But all this is determined by my code monitoring the core registers updates, that can be wrong.
290: 7fc10113 addi sp,sp,2044 # 0x7fc
294: deadc1b7 lui gp,0xdeadc
298: eef18193 addi gp,gp,-273 # 0xdeadbeef
29c: 00018213 mv tp,gp
2a0: 0dd000ef jal ra,0xb7c
But then register saved on stack.
Here, the data bus transaction is to wrong address relative to SP, expected 0x7FC – 0x20 + 0x1C = 0x7F8
But data address is not as expected, it is a write to 0x1FCC
b7c: fe010113 addi sp,sp,-32
b80: 00112e23 sw ra,28(sp)
b84: 00812c23 sw s0,24(sp)
The spec for SW:
C.SW stores a 32-bit value in register rs2 ′ to memory. It computes an effective address by adding the zero-extended offset, scaled by 4, to the base address in register rs1 ′ . It expands to sw rs2 ′, offset[6:2](rs1 ′).

Maxim

Hi Maxim,
Sorry for the delay. I was away most of the week. Wanted to take a look at this now but it looks like the VCD is missing.
So instead I created a program from your listing to see if I could recreate your issue but I don't see the same thing that you see. gp is set to 0xdeadbeef after 298: eef18193 addi gp,gp,-273 # 0xdeadbeef and b80: 00112e23 sw ra,28(sp) generates a store to address 0x7f8.
I'm attaching my trace file and the memory file I used (which is just a subset of your program listing). If you want to run it yourself with Verilator you can run fusesoc run --target=verilator_tb servant --firmware=issue17.vh --vcd --timeout=200000
Would be very interesting to see your VCD. It looks like you responded via e-mail, but perhaps you need to zip it and submit it through the github GUI for it to show up
issue17.tar.gz
Hi
I attached the VCD zipped.
Regards
Maxim

I completely forgot about this one, but was reminded earlier today. I looked at the trace now and I believe the problem is that the slave is not following the wishbone protocol. At time 256784, SERV lowers the cyc signal, but the slave keeps ack asserted. This breaks SERV
Thanks
Will check.
