Regressions under Intel SDE on native/master at commit r14-9810 vs commit r14-9796 on Linux/x86_64

New failures:

New passes:
FAIL: gcc.target/i386/apx-ndd-ti-shift.c (test for excess errors)

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 :x

where x is a random number.

2. Run gdb

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

and you should get:
...

found)...done.
