spike pk hello returns "bad syscall"

[zhuzhzh]

I follows the guide to build riscv-gnu-toolchain first. then build riscv-tools on CentOS7.8.

Everything looks fine.

#include <stdio.h>
int main() {
    printf("hello world\n");
    return 0;
}

riscv64-unknown-elf-gcc -o hello helloworld.c

which pk and which bbl can be found.

# harriszh @ pc-harriszh2 in /trunk/branch/edahub/riscv-gnu-toolchain on git:master x [5:37:58] C:255
$ which spike
/home/harriszh/.local/riscv/bin/spike

# harriszh @ pc-harriszh2 in /trunk/branch/edahub/riscv-gnu-toolchain on git:master x [5:38:05] 
$ which pk
/home/harriszh/.local/riscv/bin/pk

# harriszh @ pc-harriszh2 in /trunk/branch/edahub/riscv-gnu-toolchain on git:master x [5:37:51] 
$ spike -m128 pk hello 
bbl loader
terminate called after throwing an instance of 'std::runtime_error'
  what():  bad syscall #90463429510455458

I tried with qemu-riscv64. It's okay.

# harriszh @ pc-harriszh2 in /trunk/branch/edahub/riscv-gnu-toolchain on git:master x [5:38:07] 
$ qemu-riscv64 hello
hello world!

Do you know why spike pk doesn't work?

I had the same issue. I found out that latest riscv64-unknown-elf-gcc version is not compatible with spike which is in this repo. You can use SiFive's prebuilt GNU Embedded Tool chain. It's version working with spike pk without an error.

I had the same issue，And solved it by https://github.com/riscv/riscv-pk/issues/170 which explains tree-loop-distribute-patterns

@shitianbushuijiao thanks, it works with the change as riscv/riscv-pk#170

I still encounter this error.

But am unable to execute prorams (sclara and vector) with spike pk,

I have tried some permuations between riscv32-unknown-elf-gcc andriscv64-unknown-elf-gcc

But although program always compiles, I encounter error described here

Compiled a simple program with riscv32-unknown-elf-gcc -march=rv32gcv hello.c -o hello

Invoked PK in two ways -

1. Specified explcit path -spike $RISC/riscv32-unknown-elf/bin/pk hello --> result hang
2. . spike pk hello -bbl loader (Invokes 64 bit RISC I think) ../pk/elf.c:40: assertion failed: IS_ELF64(eh)
