Getting SIGILL with gcc12 #1161

Closed aniketor closed 10 months ago

aniketor commented 10 months ago

So I compiled an application which used Pistache on an Intel 11th gen core i7 processor and used it on Intel 13th gen core processor. I'm getting an Illegal instruction error. I have built Pistache from source.

Program received signal SIGILL, Illegal instruction.

Intel 13th has removed avx512 support at launch. Not sure if it has anything to do with it. Is there anything I can do? Additionally I used -march=x86-64 in CLFAGS instead of native but still hitting the same error. Environment details:

Host: Debian 12
Docker: Ubuntu 22.02 LTS
GCC: 12.3.0

Can you use GDB to get a disassembly of the area around the EIP where SIGILL was thrown, and post it to this bug?

kiplingw commented 10 months ago

My guess is it's probably the AVX or FMA ISA. Sometimes when running in containers AVX is disabled by the system administrators - especially on shared hosting environments because of miners.

Here's the one that crashed the program. An AVX2 instruction.

What is the contents of your cat /proc/cpuinfo (filter for just one core, or use lscpu)?

kiplingw commented 10 months ago

vpbroadcastq is AVX2 instruction. My guess is you don't have AVX2 support on the target. Interested to see what @dennisjenkins75 asked for.

@kiplingw Yes. It's an AVX2 instruction. However the cpuinfo as well as lscpu claims to have AVX2 support.

aniketor commented 10 months ago

Additional experiment I performed by trying to disable both avx512 and avx2. Compiled using -mno-avx512f -mno-avx CFLAGS. Meson build logs confirmed that the flags were applied. Still getting SIGILL on target machine. ref: https://stackoverflow.com/questions/60815316/disabling-all-avx512-extensions

I confirmed that the target machine (Intel 13th Gen) does not support avx512f.

#include <stdio.h>

int main(){
    __builtin_cpu_init ();
    if (__builtin_cpu_supports ("avx512f"))
        printf("Supports avx512f");
    return 0;
}

avx2 is supported while avx512f is not.

aniketor commented 10 months ago

As per https://docs.oracle.com/cd/E37838_01/html/E61064/gsesq.html vpbroadcastq seems to be an AVX512VL instruction. Not sure how it is related. Can we currently disable avx512 in Pistache? Or is there any way to do it?

kiplingw commented 10 months ago

Very few CPUs support AVX512. It's also controversial. Pistache doesn't require it. But your compiler optimization settings might be trying to use it because it can increase performance, such as certain copy or initialization operations.

aniketor commented 10 months ago

I was able to get it working. I removed -ftree-vectorize gcc arg along with -march=native. Then I added -mno-avx512f arg while building Pistache. Basically I disabled avx512 and turned off native optimisation flags as well. By default it uses -march=x86-64 I think.
