* Fix a crasher trying to fold each element in a comparison between two vectorsNick Lewycky2010-01-211-1/+8
| | | | | | | | | | | if one of the vectors didn't have elements (such as undef). Fixes PR 6096. Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would have <2 x i1> type if constant folding was successful and i1 type if it wasn't. This exposed a related issue in the bitcode reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94069 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | non-type-safe constant initializers. This sort of thing happens quite a bit for 4-byte loads out of string constants, unions, bitfields, and an interesting endianness check from sqlite, which is something like this: const int sqlite3one = 1; # define SQLITE_BIGENDIAN (*(char *)(&sqlite3one)==0) # define SQLITE_LITTLEENDIAN (*(char *)(&sqlite3one)==1) # define SQLITE_UTF16NATIVE (SQLITE_BIGENDIAN?SQLITE_UTF16BE:SQLITE_UTF16LE) all of these macros now constant fold away. This implements PR3152 and is based on a patch started by Eli, but heavily modified and extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84936 91177308-0d34-0410-b5e6-96231b3b80d8
