11 years agoAllow 'thread' to be used as a variable name in expressions.
Paul N. Hilfinger [Tue, 12 Mar 2013 09:03:11 +0000 (09:03 +0000)]
Allow 'thread' to be used as a variable name in expressions.

GDB treats the identifiers 'if', 'thread', and 'task' unconditionally
as expression delimiters in Ada mode, which is correct for 'if' and 'task',
but wrong for 'thread' in cases such as

      print thread

Borrowing from c-exp.y, we observe that 'thread' must be followed by
numerals, whereas identifiers never are and treat them as delimiters
only in that case.

In the process, the current also refactors and incidentally fixes the
code for rewinding the input to before the delimiting tokens.  For
example, the code

      watch expr if i > 2

fails because the input is only rewound to just before the 'i',
leaving the 'if' as part of the expression (and thus making the
rest look like trailing junk rather than a conditional clause).

gdb/ChangeLog:

    * ada-lex.l (rules): Only recognize 'thread' as a
    delimiter when followed by numerals, as for c-exp.y.
    Use new rewind_to_char function to rewind the input for
    expression-delimiting tokens.

Avoid invalid pointer to pointer conversions.

Casts between 'char **' <-> 'unsigned char **' and 'char **' <-> const
char **' are actually invalid:

  http://gcc.gnu.org/ml/gcc-help/2013-03/msg00118.html

In a nutshell, char (and variants) can alias anything, but pointers to
chars get no special treatment (cf. C99/N1256, 6.5/7).

Turns out older gcc's actually warn/complain on these constructs,
though newer one's don't:

PR gdb/15236: gdbserver write to linux memory with zero length corrupts stack

PROBLEM:

The function linux_write_memory () in linux-low.c allocates a buffer
on the stack to hold a copy of the data to be written.

  register PTRACE_XFER_TYPE *buffer = (PTRACE_XFER_TYPE *)
    alloca (count * sizeof (PTRACE_XFER_TYPE));

"count" is the number of bytes to be written, rounded up to the
nearest multiple of sizeof (PTRACE_XFER_TYPE) and allowing for not
being an aligned address. The function later uses

  buffer[0] = ptrace (PTRACE_PEEKTEXT, pid,
                      (PTRACE_ARG3_TYPE) (uintptr_t) addr, 0);

The problem is that this function can be called to write zero bytes on
an aligned address, for example when receiving an X packet of length 0
(used to test if 8-bit write is supported). Under these circumstances,
count can be zero.

Since in this case, buffer[0] may never have been allocated, the stack
is corrupted and gdbserver may crash.

SOLUTION:

Writing zero bytes should always succeed. The patch below returns
successfully early if the length is zero, so avoiding the stack
corruption.

Verified on the ARC GDB 7.5.1 port.

tstatus.exp: use UNSUPPORTED for optional features that are not supported

The current tstatus.exp tests shows PASSes if either the target
support or not the optional tstatus bits:

 PASS: gdb.trace/tstatus.exp: tstatus does not report trace stop reason
 PASS: gdb.trace/tstatus.exp: tstatus reports trace stop reason

The former (and any other similar case) should be UNSUPPORTED rather
than PASS.  That'd make it much easier to spot actually problems with
the test (e.g., the one Yao's previous patch addressed), along with
regressions and progressions.

The "not supported" paths in tstatus.exp explicitly check for output
you'd get if the feature wasn't supported, so real unexpected failures
will still be caught as FAILs.

So now e.g., where we wanted to check if tstatus reports the trace
stop reason, and if the target does support it, we get

 PASS: tstatus reports trace stop reason

if the target actually reports what we'd expect if the trace stop
reason isn't supported, we get:

 UNSUPPORTED: tstatus reports trace stop reason

and if the target reports something else unexpected, we get:

 FAIL: tstatus reports trace stop reason

That has the added bonus that the test string is always the same and
only the test results change (PASS/FAIL/UNSUPPORTED), which makes it
easier for testers see regressions, compared to the previous:

 -PASS: gdb.trace/tstatus.exp: tstatus reports trace stop reason
 +PASS: gdb.trace/tstatus.exp: tstatus does not report trace stop reason
