Chris Lattner b1d2706a4c teach libanalysis to fold int and fp loads from almost arbitrary ... 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. llvm-svn: 84936		2009-10-23 06:23:49 +00:00
