Hello,
I test currently the Ada support for RTEMS in GCC 12. We have a -mthumb
-march=armv7-a+simd -mfloat-abi=hard multilib for which the Ada RTS is
built like this:

When I try to link a test application I get this error:

sorry, unimplemented: Thumb-1 'hard-float' VFP ABI
The s-secsta.ads seems to be from the right multilib directory
(Thumb-2), however, I get a sorry message related to Thumb-1?
