Since block address values can be larger than 2GB in 64-bit code, they cannot be loaded simply using an @l / @ha pair, but instead must be loaded from the TOC, just like GlobalAddress, ConstantPool, and JumpTable values are. The commit also fixes a bug in PPCLinuxAsmPrinter::doFinalization where temporary labels could not be used as TOC values, since code would attempt (and fail) to use GetOrCreateSymbol to create a symbol of the same name as the temporary label. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220959 91177308-0d34-0410-b5e6-96231b3b80d8
