## This test verifies that llvm-objcopy correctly handles min os version load commands.
## We use separate input files since one binary is not allowed to contain more than one
## load command of this type (LC_VERSION_MIN_IPHONEOS, LC_VERSION_MIN_MACOSX,
## LC_VERSION_MIN_TVOS, LC_VERSION_MIN_WATCHOS).
