SITargetLowering::analyzeImmediate() was converting the 64-bit values to 32-bit and then checking if they were an inline immediate. Some of these conversions caused this check to succeed and produced S_MOV instructions with 64-bit immediates, which are illegal. v2: - Clean up logic Reviewed-by: Christian König <christian.koenig@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178927 91177308-0d34-0410-b5e6-96231b3b80d8
