The gdb/testsuite/README file documents GDB_DEBUG and GDBSERVER_DEBUG
flags, which can be passed to make in order to enable debugging within
GDB or gdbserver respectively.
However, when I do:
make check-gdb GDB_DEBUG=infrun
I don't see the corresponding debug feature within GDB being enabled.
Nor does:
make check-gdb GDBSERVER_DEBUG=debug \
RUNTESTFLAGS="--target_board=native-extended-gdbserver"
Appear to enable gdbserver debugging.
I tracked this down to the GDB_DEBUG and GDBSERVER_DEBUG flags being
missing from the TARGET_FLAGS_TO_PASS variable in gdb/Makefile. This
variable already contains lots of testing related flags, like
RUNTESTFLAGS and TESTS, so I think it makes sense to add GDB_DEBUG and
GDBSERVER_DEBUG here too.
With this done, this debug feature is now working as expected.
