Anyway, yes, that's what it does. dcache returns zero,
and memory_xfer_partial bails out instead of trying the
next target down the target stack.
Hi. If it will help I'll play with your testcase tomorrow.
I'll also volunteer to make a pass through the code and add some
[I mention that just in case you or someone is already in the process
of doing that.]
And the test case is in the repo now -- solib-precsave.exp.
How to run tests:
Thanks for the testcase.
You may be right about needing to test for "res == 0" but I'm less
sure now, so I'm going to leave it as is, at least for now.
dcache calls target_read (TARGET_OBJECT_RAW_MEMORY) which should DTRT.
And in fact it does with this patch. :-)
