These instructions were all assembled (using gnu toolchain) from the variants with s. This can be verified by plugging those opcodes into another disassembler. I also checked this arm7tdmi reference (page 37) to make sure that these instructions exist on this processor. I've come across no documentation that these instructions might be broken on some processors, but I'm not setup to test this on real hardware.
