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:
...
