Is is ok for you to use instead, reproducer from previous comment: > > * https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106322#c16 Nevermind; I was using gcc-11. I can reproduce the issue on ppc32/be using the (somewhat) reduced example: * https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106322#c19 For reference: % g++ -O2 -fno-tree-vectorize *.cc && ./a.out && echo "ok" ok But: % g++ --verbose -O2 *.cc && ./a.out && echo "ok" Using built-in specs.
