Hi, the test case gfortran.dg/vect/pr32380.f was found to fail on armv7l-unknown-linux-gnueabihf. The reason for this is that one out of 6 loops does not get vectorized, because this target does not support a vectorization of sqrtf.
The same test case is known to fail on powerpc-apple-darwin9 due to a different reason, see PR52229. On that target 5 out of 6 loops do not get vectorized, because of an alignment issue. That was solved at that time by declaring some targets xfail. This patch tries to solve the problem in a more general way, by classifying the target's expected result by using vect_element_align and vect_call_sqrtf attributes. This patch has been tested on armv7l-unknown-linux-gnueabihf, x86_64-unknown-linux-gnu and powerpc-apple-darwin9. OK for trunk? Regards Bernd. P.S.: Many thanks to Dominique d'Humieres for reg-testing on powerpc-apple-darwin9.
