Some are marked as unsupported but shouldn't be:

The root cause is "target vect_cmdline_needed". For those cases, they have notes as:

/* { dg-do run { target vect_cmdline_needed } } */

In function "check_effective_target_vect_cmdline_needed" of lib/target-supports.exp, it check_effective_target_arm_neon.

For our build, it is arm neon, check_effective_target_vect_cmdline_needed return 0.

A quick fix is to add another dg-do run like: /* { dg-do run { target arm*-*-*eabihf } } */

I've looked into this further and the tests make no sense. The test themselves are turned off unless the compiler needs extra command line arguments to enable some type of SIMD. See PR21292. Let's discuss this on Monday.

I've put an updated list at: http://people.linaro.org/~michaelh/incoming/hard-float-builder-diff-2.txt

The interesting ones below. They're a mix of assembler faults, ICEs, and testisims. None are due to the change in triplet so please propose your patch upstream.
