--- Comment #3 from David Christensen (drc@linux.vnet.ibm.com) ---
GCC bugzilla has been opened:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110411 to track the issue.

Suggested workaround is to enable "-mno-block-ops-vector-pair" for gcc < 11.4
when building for power10 architecture. (GCC 11.4 enables this option by
default when -mcpu=power10.)


Proposed fix:

diff --git a/config/ppc/meson.build b/config/ppc/meson.build
index 1cba44011f..160b203cb1 100644
--- a/config/ppc/meson.build

+# gcc versions < 11.4 may fail to build for power10, see
https://bugs.dpdk.org/show_bug.cgi?id=1251.
+# Explicitly specify a default used in gcc 11.4 and later to workaround the
