9 years agoDon't displaced step when there's a breakpoint in the scratch pad range

Don't displaced step when there's a breakpoint in the scratch pad range

Assuming displaced stepping is enabled, and a breakpoint is set in the
memory region of the scratch pad, things break.  One of two cases can
happen:

#1 - The breakpoint wasn't inserted yet (all threads were stopped), so
     after setting up the displaced stepping scratch pad with the
     adjusted copy of the instruction we're trying to single-step, we
     insert the breakpoint, which corrupts the scratch pad, and the
     inferior executes the wrong instruction.  (Example below.)
     This is clearly unacceptable.

#2 - The breakpoint was already inserted, so setting up the displaced
     stepping scratch pad overwrites the breakpoint.  This is OK in
     the sense that we already assume that no thread is going to
     executes the code in the scratch pad range (after initial
     startup) anyway.

This commit addresses both cases by simply punting on displaced
stepping if we have a breakpoint in the scratch pad range.

The #1 case above explains a few regressions exposed by the AS/NS
series on x86:

Enabling "maint set target-non-stop on" implies displaced stepping
enabled as well, and it's the latter that's to blame here.  We can see
the same failures with "maint set target-non-stop off + set displaced
on".

9 years agoSimplify gdb.threads/wp-replication.exp on counting HW watchpoints
Yao Qi [Fri, 30 Oct 2015 15:51:33 +0000 (15:51 +0000)]
Simplify gdb.threads/wp-replication.exp on counting HW watchpoints

Nowadays, test gdb.threads/wp-replication.exp uses a while loop to
repeatedly insert HW watchpoint, resume and check no error message
coming out, in order to count HW watchpoints  There are some
drawbacks in this way,

 - the loop could be endless.  I think this is use to making trouble
   to S/390, since we had such comment

      # Some targets (like S/390) behave as though supporting
      # unlimited hardware watchpoints.  In this case we just take a
      # safe exit out of the loop.

   I hit this today too because a GDB internal error is triggered
   on "continue" in the loop, and $done is 0 invariantly, so the loop
   can't end.
 - the code counting hardware watchpoint is too complicated.  We can
   use "set breakpoint always-inserted on" to get the result of inserting
   HW watchpoint without resuming the inferior.  In this way,
   watch_count_done and empty_cycle in c file is no longer needed.

In this patch, I change to use "set breakpoint always-inserted on" trick,
and only iterate $NR_THREADS times, to count the HW watchpoint.  In this
way, the loop can't be endless, and GDB doesn't need to resume the inferior.

mdebugread.c: Address class -> address class index

The "theclass" local is of type enum address_class, however, what it
really holds is an address class index.  Class index values by design
match the address class values up until LOC_FINAL_VALUE, but extend
beyond that, so it's not really right to store an address class index
in an enum address_class.

The fix is really the same making the 'theclass' local be of type int,
but while we're at it, we get rid of the goto, and thus the local
becomes the 'aclass_index' parameter in the new add_data_symbol

target_read_memory&co: no longer return target_xfer_status

Years ago, these functions used to return errno/EIO.  Later, through a
series of changes that intended to remove native/remote differences,
they ended up returning a target_xfer_status in disguise.

Unlike target_xfer_partial&co, the point of target_read_memory&co is
to either fully succeed or fail.  On error, they always return
TARGET_XFER_E_IO.  So there's no real point in casting the return of
target_read_memory to a target_xfer_status to pass it to memory_error.
Instead, it results in clearer code to simply decouple
target_read_memory&co's return from target_xfer_status.

ctf.c: Fix int/enum implicit cast

This patch was taken directly from Pedro's branch.

Right now, SET_INT32_FIELD is used to set enum fields.  This works in C,
but not C++.  Therefore, define the new SET_ENUM_FIELD, which casts the
value to the right enum type.

* ctf.c (SET_ENUM_FIELD): New macro.
(ctf_read_status): Use it.
(ctf_read_tp): Use it.
