Hi Christophe and Vladimir,
Here are the regressions seen on arm-none-linux-gnueabihf and arm-none-eabi.

I didn't see a bug report for these, so I will open one.
It is not clear if the test cases should be adjusted because of your
patch or if they are failing because of incorrect codegen. Attached is
the code generated for armv8_2-fp16-move-1.c (one of the test files
failing) with and without your patch.
Full command line used to compile and test armv8_2-fp16-move-1.c:
