Feature Request BTR/BTS

[kraemv]

Hello everyone,

could we add the BTR and BTS instruction to the x86 intrinsics? These instructions perform a BIT test and reset/set.

These instructions are useful for clearing/setting specific bits without using AND/OR masks.

Cheers,

Welcome. Thanks for your interest in Jasmin.

The documentation for these instructions imply that their behavior is not the same when they target a memory location or a register. I guess that the memory case would be hard to add to jasmin. Would you be satisfied if these instructions were only allowed on registers in jasmin programs?

See #932

Yes, registers are fully sufficient for me! Thank you, for the quick response.

Fixed in #932.
