I routinely run xtensa gcc testsuite in user-mode qemu, the results
are the same as when I run it on a remote board emulated by
system-mode QEMU. OTOH for the glibc testsuite the results in
user-mode and system-mode emulation used to differ significantly.
Here's my account of differences:

Most of them are due to unsupported/differently implemented
syscalls.
