           Summary: error: invalid instruction mnemonic 'xcrypt'
           Product: new-bugs
           Version: trunk
          Platform: Sun
        OS/Version: OpenBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

/usr/src/lib/libssl/crypto/../src/crypto/engine/hw_cryptodev.c:635:19: error:
invalid instruction mnemonic 'xcrypt'
        __asm __volatile("rep xcrypt-cbc" :
<inline asm>:1:6: note: instantiated into assembly here
        rep xcrypt-cbc

This happens while compiling OpenBSD -current userland code. Googling brings me
to http://www.openbsd.org/plus35.html which mentions

Add as(1) support for the VIA C3 xmove-rng and xcrypt-{ecb,cbc,cfb,ofb}

So LLVM backend needs to add support for 'as' for VIA instructions.
