Hi,
This is the latest version of the patch. I am forcing -mfloat-abi=hard
because the code generated is slightly differently depending on the
float-abi used.
Thanks,
Delia

Hi,
The previous version of this patch shared part of its code with the
store intrinsics patch
(https://gcc.gnu.org/ml/gcc-patches/2020-03/msg00145.html) so I removed
any duplicated code. This patch now depends on the previously mentioned
store intrinsics patch.
Here is the latest version and the updated ChangeLog.

... this is unstable codegen depending on the -O0 register allocator
moving the ptr argument to r3 from its initial r0.
This should really be r0 and the load instruction should load the low D
regs.
So let's add an -O2 to the dg-options and scan for the result of that.
Otherwise this is ok.
Thanks!
