5 years ago[PowerPC] Aliases for vector registers
Pedro Franco de Carvalho [Mon, 14 Jan 2019 19:28:53 +0000 (17:28 -0200)]
[PowerPC] Aliases for vector registers

This patch defines pseudo-registers "v0" through "v31" as aliases that
map to the corresponding raw "vr0" through "vr31" vector registers for
Power.

The motivation behind this is that although GDB defines these
registers as "vrX", the disassembler prints them as "vX", e.g. as the
operands in instructions such as "vaddubm v2,v1,v1".  This can be
confusing to users trying to print out the values of the operands
while inspecting the disassembled code.

The new aliases are made not to belong to any register group, to avoid
duplicated values in "info register vector" and "info register all".
The arch-specific rs6000_pseudo_register_reggroup_p function had
previously been removed since the other pseudo-registers could have
their groups inferred by their type.  It restored with this patch to
handle the aliases.  Membership for the other pseudo-registers is
still determined using the default function.

A new tests checks that GDB prints the expected values of vector
registers after they are filled by the inferior, by using both the raw
names and the aliases.  Two other existing tests are modified to also
test the aliases.

gdb/23712: Introduce multidictionary's

gdb/23712 is a new manifestation of the now-infamous (at least to me)
symtab/23010 assertion failure (DICT_LANGUAGE == SYMBOL_LANGAUGE).

An example of the problem (using test case from symtab/23010):

Reading symbols from /home/rdiez/rdiez/arduino/JtagDue/BuildOutput/JtagDue-obj-release/firmware.elf...done.
(gdb) p SysTick_Handler
dwarf2read.c:9715: internal-error: void dw2_add_symbol_to_list(symbol*, pending**): Assertion `(*listhead) == NULL || (SYMBOL_LANGUAGE ((*listhead)->symbol[0]) == SYMBOL_LANGUAGE (symbol))' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)

This assertion was added specifically to catch this condition (of adding
symbols of different languages to a single pending list).

The problems we're now seeing on systems utilizing DWARF debugging seem to
be caused by the use of LTO, which adds a CU with an artificial DIE of
language C99 which references DIEs in other CUs of language C++.

Thus, we create a dictionary containing symbols of C99 but end up
stuffing C++ symbols into it, and the dw2_add_symbol_to_list triggers.

The approach taken here to fix this is to introduce multi-language
dictionaries to "replace" the standard, single-language dictionaries
used today.

Note to reviewers: This patch introduces some temporary functions to
aide with review.  This and other artifacts (such as "See dictionary.h"
which appear incorrect) will all be valid at the end of the series.

This first patch introduces the new multidictionary and its API (which
is, by design, identical to the old dictionary interface).  It also
mutates dict_create_hashed and dict_create_linear so that they take
a std::vector instead of the usual struct pending linked list.  This will
be needed later on.

This patch does /not/ actually enable multidictionary's.  That is left
for a subsequent patch in the series.

I've done exhaustive performance testing with this approach, and I've
attempted to minimize the overhead for the (overwhelmingly) most common
one-language scenario.

On average, a -g3 -O0 GDB (the one we developers use) will see
approximately a 4% slowdown when initially reading symbols. [I've
tested only GDB and firefox with -readnow.]  When using -O2, this
difference shrinks to ~0.5%.  Since a number of runs with these
patches actually run /faster/ than unpatched GDB, I conclude that
these tests have at least a 0.5% error margin.

On our own gdb.perf test suite, again, results appear to be pretty
negligible.  Differences to unpatched GDB range from -7.8% (yes,
patched version is again faster than unpatched) to 27%.  All tests
lying outside "negligible," such as the 27% slowdown, involve a total
run time of 0.0007 (or less) with smaller numbers of CUs/DSOs (usually 10
or 100).  In all cases, the follow-up tests with more CUs/DSOs is never
more than 3% difference to the baseline, unpatched GDB.

In my opinion, these results are satisfactory.

Fix tracepoint.c:parse_tracepoint_definition leak (and one more)

Coverity points out that gdb/tracepoint.c:parse_tracepoint_definition
can leak 'cond' in this line:

      cond = (char *) xmalloc (2 * xlen + 1);

That can leak because we're in a loop and 'cond' may have already been
xmalloc'ed into in a previous iteration.  That won't normally happen,
because we don't expect to see a tracepoint definition with multiple
conditions listed, but, it doesn't hurt to be pedantically correct,
in case some stub manages to send something odd back to GDB.

At first I thought I'd just replace the xmalloc call with:

      cond = (char *) xrealloc (cond, 2 * xlen + 1);

and be done with it.  However, my pedantic self realizes that
warning() can throw as well (due to pagination + Ctrl-C), so I fixed
it using gdb::unique_xmalloc_ptr instead.

While doing this, I noticed that these vectors in struct uploaded_tp:

  std::vector<char *> actions;
  std::vector<char *> step_actions;

hold heap-allocated strings, but nothing is freeing the strings,
AFAICS.

So I ended up switching all the heap-allocated strings in uploaded_tp
to unique pointers.  This patch is the result of that.

I also wrote an alternative, but similar patch that uses std::string
throughout instead of gdb::unique_xmalloc_ptr, but in the end reverted
it because the code didn't look that much better, and I kind of
dislike replacing pointers with fat std::string's (3 or 4 times the
size of a pointer) in structures.

Move psymtabs to their own obstack

Previously, the psymtab obstack was just a pointer to the objfile

instead.  A gdb::optional is used to avoid unnecessary allocation when
the obstack is not needed.

After this patch, the psymtab code lifetime model is that, in the core
psymtab code, objects allocated on the psymtab obstack may point to
other such objects, or to objects on the per-BFD obstack -- but never
to the objfile obstack.

Note however that this invariant is only obeyed the core psymtab code,
and even there not quite fully: there is still a link from the psymtab
to the full symtab.

Symbol readers are free to work however they like; and in particular,

Introduce objfile::reset_psymtabs

This introduces a new method, objfile::reset_psymtabs, and changes
reread_symbols to use it.  This method simply destroys the existing
partial symbols and recreates the psymtab_storage object.

This patch fixes a latent bug -- namely, that reread_symbols should
clear objfile::psymbol_map, but does not.  I can submit that
separately if you'd prefer.

Introduce class psymtab_storage

This introduces a new psymtab_storage class, which holds all
psymbol-related objects that are independent of the objfile.  (This
latter contraint explains why psymbol_map was not moved; though this
could still be done with some work.)

This patch does not yet change where psymtab allocation is done --
that comes later.  This just wraps everything in a single object to
make further transformations simpler.

Note that a shared_ptr is used to link from the objfile to the
psymtab_storage object.  The end goal here is to allow a given symbol
reader to simply attach to the psymtab_storage object to the BFD, then
reuse it in later invocations; shared_ptr makes this simple to reason
about.

gdb: Remove support for old mangling schemes

An upcoming sync with gcc's libiberty [1] will remove support for old
mangling schemes (GNU v2, Lucid, ARM, HP and EDG).  It will remove the
cplus_demangle_opname function, so we need to get rid of its usages in
GDB (it's a GNU v2 specific function).

I think the changes are mostly relatively obvious, some hacks that were
necessary to support overloaded operators with GNU v2 mangling are not
needed anymore.

The change in stabsread.c is perhaps less obvious.  I think we could get
rid of more code in that region that is specific to old mangling
schemes, but I chose to do only the minimal changes required to remove
the cplus_demangle_opname uses.  There is also a detailed comment just
above that explaining how GNU v2 and v3 mangled symbols are handled, I
decided to leave it as-is, since I wasn't sure which part to remove,

5 years agogdb: Avoid signed integer overflow when printing source lines
Andrew Burgess [Mon, 7 Jan 2019 07:26:35 +0000 (07:26 +0000)]
gdb: Avoid signed integer overflow when printing source lines

When printing source lines with calls to print_source_lines we need to
pass a start line number and an end line number.  The end line number
is calculated by calling get_lines_to_list and adding this value to
the start line number.  For example this code from list_command:

    print_source_lines (cursal.symtab, first,
                        first + get_lines_to_list (), 0);

The problem is that get_lines_to_list returns a value based on the
GDB setting `set listsize LISTSIZE`.  By default LISTSIZE is 10,
however, its also possible to set LISTSIZE to unlimited, in which
case get_lines_to_list will return INT_MAX.

As the parameter signature for print_source_lines is:

  void print_source_lines (struct symtab *, int, int,
                           print_source_lines_flags);

and `first` in the above code is an `int`, then when LISTSIZE is
`unlimited` the above code will result in signed integer overflow,
which is undefined.

The solution in this patch is a new class source_lines_range that can
be constructed from a single line number and a direction (forward or
backward).  The range is then constructed from the line number and the
value of get_lines_to_list.

gdb/testsuite: Remove interactive prompt case from mi_gdb_test

I noticed that when running this test:

  make check-gdb RUNTESTFLAGS="--target_board=native-gdbserver gdb.mi/mi-break.exp"

I would occasionally see some UNRESOLVED test results like this:

  (gdb)
  PASS: gdb.mi/mi-break.exp: mi-mode=separate: breakpoint at main
  Expecting: ^(kill[
  ]+)?(.*[
  ]+[(]gdb[)]
  [ ]*)
  kill
  &"kill\n"
  ~"Kill the program being debugged? (y or n) [answered Y; input not from terminal]\n"
  =thread-group-exited,id="i1"
  ERROR: Got interactive prompt.
  UNRESOLVED: gdb.mi/mi-break.exp: mi-mode=separate:

The problem appears to be that the expect buffer fills up to include
the '(y or n)' prompt without including the following lines.

The pattern supplied by the outer test script is looking for the
following lines.  As the following lines are not present then expect
matches on the interactive prompt case rather than the case for the
user supplied pattern.

The problem with this is that we are not really at an interactive
prompt, GDB is providing an answer for us and then moving on.  When I
examine a successful run of the test the output from GDB is identical,
the only difference is where expect happens to buffer the output from
GDB.

This patch remove all special handling of the interactive prompt
case.  This means that if we ever break GDB and start seeing an
unexpected interactive prompt then tests will rely on a timeout to
fail, instead of having dedicated interactive prompt detection, but
this solves the problem that an auto-answered prompt looks very
similar to an interactive prompt.

With this patch in place I can now leave the following loop running
indefinitely, where before it would fail usually after ~10
iterations.

  while make check-gdb RUNTESTFLAGS="--target_board=native-gdbserver gdb.mi/mi-break.exp"; \
  do /bin/true; \
  done

      Highlight source code using GNU Source Highlight

introduced a regression in the test gdb.linespec/explicit.exp, in
which a request is made to GDB to print a reverse sequence of lines,
from +10 to -10 from the current line number.  The expected behaviour
is that GDB prints nothing.  The above commit changed this so that GDB
now prints:

  Line number 32 out of range; /path/to/gdb/testsuite/gdb.linespec/explicit.c has 71 lines.

which is a little confusing.

This commit fixes the regression, and restores the behaviour that GDB
prints nothing.

While I was passing I noticed a call to `back` on a std::string that I
was concerned could be empty if the request for source lines returns
an empty string.  I don't know if it would be possible for a request
for lines to return an empty string, I guess it should be impossible,
in which case, maybe this should be an assertion, but adding a `empty`
check, seems like an easy and cheap safety net.

* source.c (print_source_lines_base): Handle requests to print
reverse line number sequences, and guard against empty lines
