The assembler currently strictly verifies that immediates for s16imm operands are in range (-32768 ... 32767). This matches the behaviour of the GNU assembler, with one exception: gas allows, as a special case, operands in an extended range (-65536 .. 65535) for the addis instruction only (and its extended mnemonic lis). The main reason for this seems to be to allow using unsigned 16-bit operands for lis, e.g. like lis %r1, 0xfedc. Since this has been supported by gas for a long time, and assembler source code seen "in the wild" actually exploits this feature, this patch adds equivalent support to LLVM for compatibility reasons. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184946 91177308-0d34-0410-b5e6-96231b3b80d8
