I can't speak to them all off the top of my head but psxfenv01.exe is an
expected fail at this point because there is no implementation of POSIX
fenv.h for SPARC yet.

psxmsgq03 may have broken due to the recent error code change and it
just got missed.

Can you post a link to the offending content? Or file a ticket?

sis was recently split out of gdb and is a standalone simulator that
supports SPARC and RISC-V. It is quite improved as a simulator but
RTEMS documentation has always (since 1995) used it as the easiest
BSP to run code for. So there are potentially many places this is described
that are now out of date for the master.

I had to update the RTEMS class I teach to show how it used to be and how it
is now.

I'm leaving this one to someone else.

One is the binary before it is installed. The one in
$HOME/quick-start/rtems/5/bin
is the installed copy.

Ditto

It does include tools related to the dynamic loading which would be
required to build the RTEMS tests. If you run tests by hand, then
you won't need rtems-tester.

Most of the contents of rtems-tools will be needed in a normal
workflow. Likely not covoar unless you work with coverage.
