You're right. I will stop using `[MachCode]`.

Thank you for your suggestion.
I prefer the former expression.
However, if hsdis is loaded successfully, the disassembled code will appear in `[Disassembly]` instead of `[MachCode]`, so I don't think "unable to show disassembled code in MachCode section" is appropriate.
Do you think "undisassembled" is clunky? "undisassembled" is also used in [src/hotspot/share/code/nmethod.cpp#L3428](https://github.com/openjdk/jdk/blob/c220b1358c91bce2eb7515e9f600004c7b975ee6/src/hotspot/share/code/nmethod.cpp#L3428), so I don't think it's too clunky. 
So, for example, how about `Loading hsdis library failed, undisassembled code is shown in MachCode section`? If "undisassembled" is clunky, I think it could be "not disassembled" for example.
