[llvm-commits] Patch: avoid legalization assert

[Duncan Sands]

Hi Mon Ping, if I understand right the problem is that v2i64 is legal,
but i64 is not, and that when we try to scalarize this
  0x2b1d9c8: v2i64 = sdiv 0x2b1ddc8, 0x2b1dfc8
into a pair of libcalls, we end up with expressions in terms of the
elements (i.e. of i64 type) but those types aren't legal.  The
point of running llc with -disable-mmx is that there is then no
sdiv vector instruction I suppose.  Hmmm, tricky :)

Ciao,

Duncan.
