error: warning(link): unexpected LLD stderr:
ld.lld: warning: Linking two modules of different target triples: '/home/alexrp/Source/zig-bootstrap/zig/.zig-cache/o/01689e06a60d64e2c89337e609a9fed9/zig.o' is 'arm-unknown-linux-gnueabihf' whereas 'ld-temp.o' is 'armv6kz-unknown-linux-gnueabihf'

Not sure what could be causing this.

[andrewrk]

When producing the LLVM target triple, it needs to select the appropriate LLVM subarch for arm. In Zig we model this with CPU features instead of a "sub architecture" concept.

[alexrp]

I'm just not clear on where exactly that subarch gets added to the triple. 🤔

[alexrp]

Oh, sorry, are you saying we don't currently add the appropriate Arm version to the triple but we should?

[andrewrk]

Yeah. Or maybe it had to do with assembly files taking the target differently. This is definitely my fault, I remember noticing it and thinking, "oh that's an easy fix" and then never doing it.
