From c579d978a3d8f20087e55ba3ed7c8fb5b369e6e7 Mon Sep 17 00:00:00 2001 From: Dan Gohman Date: Tue, 9 Sep 2008 01:02:47 +0000 Subject: Extend the vcmp/fcmp LLVM IR instructions to take vectors as arguments and, if so, to return a vector of boolean as a result; Extend the select LLVM IR instruction to allow you to specify a result type which is a vector of boolean, in which case the result will be an element-wise selection instead of choosing one vector or the other; and Update LangRef.html to describe these changes.
