## Message

```
Fix `lakemont` CpuModel (#9099)

Lakemont has no x86, no MMX, no SSE and no way of handling any fp-math. In theory LLVM is able to implicitly use the soft-float emulation library calls to legalize any such operation but, given Zig's use of many non-standard features, sometimes we hit a weak spot in the X86 codegen backend.

Consider this as a work-around for this LLVM problem, fixing the problem in LLVM is not so high in my todo list as the target is pretty niche and Intel axed it in '19.
