Hi Everyone,
I'm working on the GCC Compile Farm. I'm on machine
gcc118.fsffrance.org, which is an ARMv8.a machine. The cpu offers CRC
and Crypto. The machine runs openSUSE Leap 42.1.
When I attempt to engage the CRC and Crypto extensions the program
fails to compile. CRC is shown below, but AES and SHA result in
similar failures.
The unusual thing is, there is no <arm_acle.h> header. Missing
<arm_acle.h> is common for Android and Apple, but Linux usually
supplies it.
Does anyone know how to enable the CRC and Crypto extensions on openSUSE?
Thanks in advance.

If you use a recent version of openSUSE, GCC should provide the arm_acle.h file. I
verified it on Tumbleweed, with GCC7 and GCC8.

It depends on what you consider "supports" I guess? I don't think we
shipped binutils on 42.1 yet that allowed you to assemble crc enabled code.
Sorry to ask. I need to know if it is my problem or
someone else's
problem. If its my problem I need to fix it.
I would really recommend to update the system. Can you ask the gcc
Compile Farm people to do that for you?
If not, do you have root access? If so, you should be able to create a
chroot and just run your tests from there. The kernel shouldn't really
care whether you're running crc operations:

We don't control the platform; someone else controls it.
We are expected to "just work" regardless of the environment.
I don't disagree with you about the upgrade. But I would be pissing
into the wind if we followed the abondonware development model. The
mailing list and bug tracker would fill up with fodder for those not
using the latest distros. It is easier on us to support the platform
properly.

Hm, IIRC 42.1 predates any crc support from our side, so I wouldn't be
very surprised if things break.
If you say "you" are expected to just work, does that mean gcc? In that
case, I would expect that the header you're looking for gets detected by
configure and crc should be optionally disabled if it can't find it?
Again, I'm fairly confident that even binutils in 42.1 doesn't know how
to assemble crc instructions. That only came later.
