            Bug ID: 269792
           Summary: 13.2-BETA2: sigILL: lzma does not compile to westmere
           Product: Base System
           Version: 13.1-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: pmc@citylink.dinoex.sub.org

Target is i3-540 (westmere)
Build machine is E5-2660v3 (haswell) - but that's not relevant.

Result is this:

# ./xz < /dev/zero > /dev/null                                            
Illegal instruction (core dumped)                                         

Wikipedia says that the i3-540 is westmere.
The compiler itself, when configured CPUTYPE?=native, says that
the chip is westmere (but it shows a lot of more detailed flags
in addition).
But when then compiling for cpu westmere, the code is defect.
(Compiling on-site with cpu "native", gives working code.)

Bottomline: one cannot currently compile for target westmere on a build
machine.
