Illegal instruction errors on old ThinkPad (popcnt, pcmpestri) #4124

Closed Akuli closed 1 year ago

Akuli commented 1 year ago

What version of Bun is running?

0.7.3

What platform is your computer?

Linux 5.10.0-24-amd64 x86_64 unknown

What steps can reproduce the bug?

Download bun-linux-x64-baseline and run various commands on my old thinkpad:

bun-linux-x64-baseline/bun install
bun-linux-x64-baseline/bun dev

What is the expected behavior?

Not sure. Maybe at least baseline version should work. If not, just close this issue.

What do you see instead?

akuli@Akuli-ThinkPad:~/piirimaker$ bun-linux-x64-baseline/bun --version
0.7.3
akuli@Akuli-ThinkPad:~/piirimaker$ bun-linux-x64-baseline/bun install
Illegal instruction
akuli@Akuli-ThinkPad:~/piirimaker$ bun-linux-x64-baseline/bun dev
[6.00ms] bun!! v0.7.3 (a9b3d583)

Illegal instruction

With gdb (after switching to the right thread) I see this happens at a popcount instruction:

s

Similarly bun dev crashes at a pcmpestri instruction when the first request comes.

Note that I have sse4_1 but not sse4_2. If I googled correctly, both missing instructions are new in sse4_2.

Hi man, i'm having the same issue like yours, i was changing cpus, and then i saw this on gdb: image

so, i was changing cpus from core 2 duo e6850, to xeon e5450, my linux kernel (uname -mrs) is Linux 5.15.0-79-generic x86_64

eclairevoyant commented 1 year ago

see https://github.com/oven-sh/bun/issues/67#issuecomment-1205545144, use one of the baseline builds

also this is a duplicate

Akuli commented 1 year ago

As far as I can tell, I am using the latest baseline build.

We are unlikely to support very old CPUs like ThinkPad, sorry.
