Hi @cattokomo,

After a bit of investigating, this instruction should definitely be available even when compiling for Thumb2. I suspect maybe your clang is targetting Armv7-M. What is the target provided by clang -v ?

[mbekkomo]

Hello @cognet.

Here's the output of clang -v.

~ $ clang -v
clang version 18.1.7
Target: armv7a-unknown-linux-android24
Thread model: posix
InstalledDir: /data/data/com.termux/files/usr/bin

@cattokomo sorry for taking so long to respond, I'd like to fix that, but it sounds like a Termux-specific thing, can you help me reproduce the problem? I assume I have to install Termux on an Android device, but my phone has a 64bits arm, so it brings a 64bits compiler, and that seems to work fine here. Do you know of a way I could get access to a Termux running on 32bits arm?
Thank you!

I can try it on my device, it's running on 32 bit mode.

@cattokomo ideally I'd need a shell on it, to try various things

You can try to use termux-docker. It is not the best solution since it uses qemu under the hood (if you use aarch64 or armv7) but it will give you a kind of device for tests.
