What model CPU chip is on your board? What does "cat /proc/cpuinfo" say?

That instruction seems to be:
evldd r7,0(r4)
which is an instruction for SPE (Signal Processing Engine):
evldd[x] Vector Load Double Word into Double Word [Indexed]
which is described on pdf page 513 of:

processors
> Could you please anybody suggest some clue to solve the above issue ?
Is there a way to run the program such that the code intentionally avoids
using SPE instructions? Set a shell environment variable, or temporarily
move some directory of SPE support code to another name such that the SPE
code is not found (such as something like "mv /lib/spe /lib/spe.save"), etc.?
Your e-mail domain says freescale.com, which has been associated with a
designer/fabricator/marketer of these CPU chips. What do your co-workers say?
