FAIL: gcc.target/i386/avx256-unaligned-store-3.c scan-assembler vmovupd.*movv2df_internal/4

To reproduce the test failures:

$ cd gcc
$ make check RUNTESTFLAGS="--target_board='unix{-m32,}' i386.exp=failed-test"

If a run-time test failure fails to reproduce, please run the executable
under Intel SDE which can be downloaded from

https://www.intel.com/content/www/us/en/developer/articles/tool/software-development-emulator.html

$ ..../sde -future -- ./executable

To debug executable under SDE:

1. Turn on SDE debug:

$ ..../sde -future -debug -- ./executable

and you should get:

Application stopped until continued from debugger.
Start GDB, then issue this command at the (gdb) prompt:
  target remote :xxxxx

where xxxxx is a random number.

2. Run gdb

$ gdb ./executable
...
(gdb) target remote :xxxxx

and you should get:
...
