And how many thousand lines of code (including libraries, etc. that may
have been pulled in)?
I had just this discussion yesterday at work with someone. These days,
silicon (even going into space) is much cheaper than people. Sure, you
could optimize a hand crafted little routine in assembler. Or, you could
just load up RTEMS, compile your program, link in newlib, etc., and have
it working in a day. If you've got 2 MByte of memory, nobody cares
whether you use 1kbyte or 50kbyte.
