Failed PPC64 compile when using Power7 loads and stores?
...tails of the host:
Operating System Details
Distributor ID: Ubuntu
Description: Ubuntu 16.04.6 LTS
Release: 16.04
Codename: xenial
...
OS/Arch: linux/ppc64le
clang version 3.8.0-2ubuntu4 (tags/RELEASE_380/final)
==========
Compile is OK on my old PowerMac G5, GCC112 and GCC119 from the
compile farm. Unfortunately, the compile farm only tests GCC and XLC.
The Clang compiler does not work.
Thanks in advance.

sysconf and _SC_LEVEL1_DCACHE_LINESIZE returns 0?
...:
$ cat /etc/centos-release
CentOS Linux release 7.3.1611 (AltArch)
I'm trying to determine L1 data cache size. When the following code
runs it returns 0. The man pages state -1 is an error, so I think its
claiming to succeed.
cacheLineSize = sysconf(_SC_LEVEL1_DCACHE_LINESIZE);
GCC119, which is also a S822 Power8 running AIX, returns 128.
Does anyone know what I might be doing wrong under Cent? Or maybe, how
can I retrieve the L1 data cache line size?
Thanks in advance.
