Sure, done in the updated patch.  I'd checked that if `FAIL`s with `llc -mtriple=i386-pc-solaris2.11 --stack-alignment=16`



================
Comment at: llvm/lib/Target/X86/X86Subtarget.cpp:270
+  else if (isTargetSolaris() && !In64BitMode)
+    stackAlignment = Align(4);

Ah, I missed that.  Fixed in the updated patch.  Thanks.
