[lldb-dev] [OS X] [Usage] register write for xmm registers

I'm trying to debug a problem with floating-point traps on 64-bit Mac OS X, and it would be extremely useful to be able to change values in xmm registers. I'm working with command-line LLDB, because I'm partially sighted and the Xcode GUI is just too complicated and confusing for me. I've managed to get to the syntax for:

        register write xmm0 "{0x00 0x01 ... 0x0f}"

I haven't managed to find any other forms that are more human-friendly. The ability to be able to type in floating-point numbers in decimal would be a lot easier. Does this exist?

thanks in advance,

John Dallman
