Are you running the test by hand?  When I look at the failure in my gcc
test run log file I see that it was compiled with -O2 -ftree-vectorize as
well as -march=armv8.2-a+sve.  I didn't specify those options, they
got added on from the dg-options entry in the test program.

From my gcc testsuite log file:

spawn -ignore SIGHUP /home/sellcey/tot/obj/gcc/gcc/xgcc
-B/home/sellcey/tot/obj/gcc/gcc/ -fno-diagnostics-show-caret
-fno-diagnostics-show-line-numbers -fdiagnostics-color=never
-march=armv8.2-a+sve -O2 -ftree-vectorize --save-temps -ffat-lto-objects
-fno-ident -c -o clastb_1.o
