Loop-dedicated benchmark suites?

Hi,

I want to evaluate the effectiveness of a research C source-to-source
optimizer on benchmarks. Especially, I'm interested in the supported
loop transformations.

Which freely available testsuites contain a large number of loops?
Are there possibly benchmark suites that focus on loops?

One of the supported loop transformations I want to evaluate is loop
unswitching. However, the benchmarks from the UTDSP testsuite I
recently considered have no potential for this transformation,
i.e. the loop structures do not allow to "unswitch" loops. Is this a
normal situation for unswitching?

Regards,
Stephan
