It’s strange that the above testing on my local x86 machine with the latest gcc
had less failure than the following:
[opc@qinzhao-ol8u3-x86 build-boot]$ make check-gcc
RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} i386.exp=auto-init*' &> log &

I am wondering whether the default value for “-march” option might be
different on different platforms? ( I see if I add -march=cascadelake, then I
will get more failures).
I have a patch to the above FAILURES as:
Please take a look and let me know your comments:
thanks.
