2528f8ada6 [gdb/testsuite] add jit-elf-util.h and run jit function
Splits ELF related symbols into a separate jit-elf-util.h header and
enhances it with a few more.

Intention is to make adding new JIT tests possible without repeating
most of the common boilerplate.

As a test enhancement, jit-elf-main.c now calls the renamed function
after registering the jit object and ensures it returns an expected
result.

gdb/testsuite/ChangeLog:

2020-02-18  Mihails Strasuns  <mihails.strasuns@intel.com>

	* gdb.base/jit-elf-util.h: New header file.
	* gdb.base/jit-elf-main.c: Use jit-elf-util.h, add a call to
	  the renamed JIT function to verify its result.

aff4e759b8 [gdb/testsuite] define jit function name via macro
Replaces previous approach with patching resulting ELF binary after
loading - now that each test iteration works on a separately compiled
binary it is not necessary anymore.

Tests are still being ran without debug info to preserve original test
functionality but this change opens up the possibility to enable debug
info if needed too.

gdb/testsuite/ChangeLog:

2020-03-27  Mihails Strasuns  <mihails.strasuns@intel.com>

	* lib/jit-elf-helpers.exp: Supply -DFUNCTION_NAME macro
	  definition when compiling jit-elf-solib.co.
	* gdb.base/jit-elf-main.c: Stop patching jit function name.
	* gdb.base/jit-elf-solib.c: Use FUNCTION_NAME macro value as a
	  function name.

80ad340c90 [gdb/testsuite] use -Ttext-segment for jit-elf tests
Removes the need to manually relocate loaded ELF binary by using a fixed
constant as both mmap base address and as a requested first segment
address supplied to the linker.

In future will enable JIT tests with a valid DWARF debug info.  Current
tests still need to compile without a debug info though, because they do
a function name modification.

gdb/testsuite/ChangeLog:

2020-02-18  Mihails Strasuns  <mihails.strasuns@intel.com>

	* lib/jit-elf-helpers.exp: Supply -Ttext-segment linker flag and
	  define LOAD_ADDRESS/LOAD_INCREMENT macros for the compiled binaries.
	* gdb.base/jit-elf-main.c: Use LOAD_ADDRESS/LOAD_INCREMENT to
	  calculate the mmap address.

f801207197 [gdb/testsuite] add lib/jit-elf-helpers.exp
New utility library to be used by jit-elf tests responsible for
compiling binary artifacts. In the next commit the compilation process
will become more complicated because of extra mandatory flag - keeping
it in one place will make tests less fragile.

ebf470809e gdb: change duplicate test name in gdb.base/jit-so.exp
When running gdb.base/jit-so.exp, we see duplicate test names:

d30dcd1288 gdb/testsuite: Detect and warn about duplicate test names
Building on the previous commit, this patch detects when two tests
have the same test name and causes Dejagnu to print a new result type
'# of duplicate test names' in the result summary.  A line starting
with 'DUPLICATE: ' is also added to the gdb.sum and gdb.log files.

The DUPLICATE markers will be printed the second time a duplicate test
name is seen, and every time after that.  So you might see:

  PASS: gdb.base/sometest.exp: foo
  PASS: gdb.base/sometest.exp: bar
  PASS: gdb.base/sometest.exp: foo
  DUPLICATE: gdb.base/sometest.exp: foo
  PASS: gdb.base/sometest.exp: baz
  PASS: gdb.base/sometest.exp: foo
  DUPLICATE: gdb.base/sometest.exp: foo

However, the results will report a duplicate count of 1, indicating
that just one test name (foo) was duplicated.

Currently if the tests are run in parallel mode the new result type is
not merged into the combined summary file so users will need to run in
non-parallel mode to check this result.  Similarly, the 'DUPLICATE: '
markers will not be merged into the final gdb.sum file.  A later
commit will fix this.

gdb/testsuite/ChangeLog:

	* lib/check-test-names.exp (all_test_names): New module variable.
	(counts): Add 'duplicates' field.
	(_check_duplicates): New procedure.
	(check): Also check for duplicates.
	(do_log_summary): Print duplicates count.
	(do_reset_vars): Reset counter for duplicate test names, and
	discard all know test names.

34584c091b gdb/testsuite: Detect and warn if paths are used in test names
A new library is introduced that hooks into the core of Dejagnu and
detects when a test's name includes either the source or build paths.
If any offending test names are detected then Dejagnu will print a
new result type, '# of paths in test names'.  Users should treat this
result type just like other bad results types, and aim not to increase
this number.

As well as displaying the total number of offending tests as part of
the final results, a new marker is included in both the gdb.log and
gdb.sum files, this marker starts with 'PATH: ', so an offending test
would be expected to appear like this:

  PASS: gdb.base/sometest.exp: Loaded /path/to/build/testsuite/foo.exe
  PATH: gdb.base/sometest.exp: Loaded /path/to/build/testsuite/foo.exe

This should make it easier to track down offending tests.

Currently for a local run on my machine, I don't see any offending
test names, but it is possible that different targets, or different
configurations, might currently be breaking the no paths rule.

In order to get this working I have needed to wrap two core Dejagnu
functions, log_summary, and reset_vars.  Relying on core functions
that are not part of any API is always going to be risky, given the
relatively slow rate of Dejagnu change this is probably OK for now,
and we can possibly upstream some changes to Dejagnu that would allow
this functionality to be supported in a more official way later on.

Currently if the tests are run in parallel mode the new result type is
not merged into the combined summary file so users will need to run in
non-parallel mode to check this result.  Similarly, the 'PATH: '
markers will not be merged into the combined summary file.  A later
commit will fix this.

gdb/testsuite/ChangeLog:

	* lib/gdb.exp: Include check-test-names.exp library.
	* lib/check-test-names.exp: New file.

5eb68a39a2 Fix Ada value printing on PPC64
The val_print removal patches introduced an Ada regression on PPC64
(probably any big-endian system).

The issue comes because value_field does not understand that Ada
wrapper fields can be bitfields that wrap a non-scalar type.  In this
case the value is already left-justified, so the justification done
there does the wrong thing.

Perhaps it would be good, eventually, to change value_field to
understand this case.  In the meantime this implements an Ada-specific
solution.

e000211765 [gdb/testsuite] Change kfail into xfail in gdb.ada/packed_tagged.exp
Test-case gdb.ada/packed_tagged.exp contains a kfail:
...
setup_kfail "gnat compiler bug" *-*-*
...

Kfails are used to indicate problems in gdb, xfails are used to indicate
problems in the environment.

A bug in the gnat compiler is a problem in the environment rather than gdb.

Fix this by changing the kfail into an xfail.

Tested on x86_64-linux.

113ee09a64 [gdb/testsuite] Fix gdb.cp/cpexprs-debug-types.exp inclusion
When running tests using RUNTESTFLAGS="cpexprs.exp cpexprs-debug-types.exp",
we have:
...
Running src/gdb/testsuite/gdb.cp/cpexprs-debug-types.exp ...
Running src/gdb/testsuite/gdb.cp/cpexprs.exp ...
...

In the first test-case, we have -fdebug-types-section as expected:
...
Running src/gdb/testsuite/gdb.cp/cpexprs-debug-types.exp ...
g++ -fno-stack-protector -fdiagnostics-color=never \
  -fdebug-types-section \
  -c -g \
  -o outputs/gdb.cp/cpexprs-debug-types/cpexprs-debug-types0.o \
  src/gdb/testsuite/gdb.cp/cpexprs.cc
...
but in the second test-case, we have also have -fdebug-types-section:
...
Running src/gdb/testsuite/gdb.cp/cpexprs.exp ...
g++ -fno-stack-protector -fdiagnostics-color=never \
  -fdebug-types-section \
  -c -g -g \
  -o outputs/gdb.cp/cpexprs/cpexprs0.o \
  src/gdb/testsuite/gdb.cp/cpexprs.cc
...

This is due to using a global variable flags, which is set in
cpexprs-debug-types.exp and tested for existence in cpexprs.exp.

Fix this by using a more robust inclusion mechanism, that is:
- move the bulk of the test-case cpexprs.exp to cpexprs.exp.in,
- include it from cpexprs.exp and cpexprs-debug-types.exp, and
- set flags in both .exp files

ba3e70b008 Clean-up gdb.ada test names
This patch fixes all duplicate and tail parentheses test names.
These can really hinder automated test analysis such as used by
the buildbot.

Before:
$ cat testsuite/gdb.sum | egrep "^(PASS|FAIL|XPASS|XFAIL|KPASS|KFAIL)" \
  | sort | uniq -c | sort -n | grep -v " 1 "
      2 PASS: gdb.ada/attr_ref_and_charlit.exp: print s'last
      2 PASS: gdb.ada/bp_on_var.exp: set breakpoint pending off
      2 PASS: gdb.ada/complete.exp: complete p pck.inne
      2 PASS: gdb.ada/fun_overload_menu.exp: multiple matches for f (f (1, null))
      2 PASS: gdb.ada/type_coercion.exp: p q
      2 PASS: gdb.ada/unc_arr_ptr_in_var_rec.exp: print My_P_Object.Ptr when no longer null
      3 PASS: gdb.ada/fun_overload_menu.exp: 1

After:
<empty>

For parentheses, I've audited all occurrences of trailing parentheses.
Most offenders are of the form:

   gdb_test "p func (..)" $expected_result

I've either added a unique test name or simply removed the whitespace
between the function name and the argument list.

7666722fce [gdb/symtab] Save modules in .debug_names
When running test-case gdb.fortran/info-modules.exp with target board
debug-names, I run into:
...
FAIL: gdb.fortran/info-modules.exp: info modules: check for entry \
  'info-types-2.f90', '18', 'mod2'
...

In more detail, comparing the behaviour of the executable without and with
.debug_names section, we have:
...
-$ gdb -batch info-modules -ex "info modules"
+$ gdb -batch info-modules.debugnames -ex "info modules"
 All defined modules:

-
 File /data/gdb_versions/devel/src/gdb/testsuite/gdb.fortran/info-types.f90:

...

This is due to the fact that the .debug_names section does not contain
DW_TAG_module entries.

3ee6bb113a [gdb/symtab] Fix incomplete CU list assert in .debug_names
Consider the following two-file test-case:
...
$ cat main.c
extern int foo (void);

int
main (void)
{
  int sum, a, b;
  sum = a + b + foo ();
  return sum;
}
$ cat foo.c
int
foo (void)
{
  return 3;
}
...

Compiled like this:
...
$ clang-10 -gdwarf-5 -gpubnames -c main.c
$ clang-10 -gdwarf-5 -c foo.c
$ clang-10 -gdwarf-5 -gpubnames main.o foo.o
...

When loading this exec into gdb, we run into this assert:
...
$ gdb a.out
Reading symbols from a.out...

warning: Section .debug_aranges in a.out entry at offset 0 \
  debug_info_offset 0 does not exists, ignoring .debug_aranges.
src/gdb/dwarf2/read.c:6949: \
  internal-error: cutu_reader::cutu_reader(dwarf2_per_cu_data*, \
  		                           abbrev_table*, int, bool): \
  Assertion `this_cu->length == cu->header.get_length ()' failed.
...

The problem is that the determined length of the CU:
...
(gdb) p /x this_cu->length
$4 = 0x26a
...
does not match the actual length:
...
(gdb) p /x cu->header.get_length ()
$5 = 0x59
...

The length of the CU is determined in create_cus_from_debug_names_list, and
set based on this list in the .debug_names section:
...
  Compilation Unit offsets [
    CU[0]: 0x000000c7
  ]
...
and it is assumed that this is a complete list, so the size of the CU is
calculated using the end of the .debug_section at 0x331, making it 0x331 -
0xc7 == 0x26a.

However, the CU list is not complete:
...
$ llvm-dwarfdump -debug-info a.out \
  | grep "Compile Unit" \
  | sed 's/Compile Unit.*//'
0x00000000:
0x0000002e:
0x000000a5:
0x000000c7:
0x00000120:
0x00000157:
0x0000030f:
...
In particular, because the CU for foo.c is there at 0x120 (the rest of the CUs
is due to openSUSE having debug info for various linked in objects).

Fix the assert by not assuming to know the length of CUs in
create_cus_from_debug_names_list (if the .debug_names is not produced by GDB),
and setting it to 0, and setting it later to the actual length.

Note that this does not fix the .debug_aranges warning, that's PR25969.

Build and tested on x86_64-linux, with native and debug-names.

86cd6bc8f6 gdb/fortran: Allow Flang MAIN_ in Fortran testing
Name of fortran main function for Flang compiler is MAIN_ while
for gfortran it is MAIN__ . In test cases MAIN__ is hardcoded for
the purpose of inserting breakpoint.

New proc is added to detect main function name depending on the
compiler used.
Fortran specific version of runto_main named fortran_runto_main
is added.

This commit adds support for Flang main function, there should be
no change for gfortran.

4343499695 [gdb] Fix catch throw regexp matching
When running test-case gdb.mi/mi-catch-cpp-exceptions.exp, we have:
...
FAIL: gdb.mi/mi-catch-cpp-exceptions.exp: all with invalid regexp: run until \
  breakpoint in main (unknown output after running)
...

This is a regression since commit 596dc4adff "Speed up psymbol reading by
removing a copy".

Before that commit, we have:
...
$ gdb \
    -batch \
    ./outputs/gdb.mi/mi-catch-cpp-exceptions/mi-catch-cpp-exceptions \
    -ex "break 67" \
    -ex "catch throw -r blahblah" \
    -ex r
Breakpoint 1 at 0x4008e5: file mi-catch-cpp-exceptions.cc, line 67.
Catchpoint 2 (throw)

Breakpoint 1, main () at mi-catch-cpp-exceptions.cc:67
67                  return 1;   /* Stop here.  */
...
In other words:
- we set a breakpoint somewhere in main,
- we set a catchpoint with a regexp that is intended to not match any
  exception, and
- run to the breakpoint, without the catchpoint triggering.

After the commit, we have:
...
$ gdb \
    -batch \
    ./outputs/gdb.mi/mi-catch-cpp-exceptions/mi-catch-cpp-exceptions \
    -ex "break 67" \
    -ex "catch throw -r blahblah" \
    -ex r
Breakpoint 1 at 0x4008e5: file mi-catch-cpp-exceptions.cc, line 67.
Catchpoint 2 (throw)

Catchpoint 2 (exception thrown), 0x00007ffff7ab037e in __cxa_throw () from \
  /usr/lib64/libstdc++.so.6
...
In other words, the catchpoint triggers.

This is caused by this bit of the commit:
...
       type_name = cplus_typename_from_type_info (typeinfo_arg);

       canon = cp_canonicalize_string (type_name.c_str ());
-      if (!canon.empty ())
-       std::swap (type_name, canon);
+      name = (canon == nullptr
+	      ? canon.get ()
+	      : type_name.c_str ());
     }
   catch (const gdb_exception_error &e)
     {
       exception_print (gdb_stderr, e);
     }

-  if (!type_name.empty ())
+  if (name != nullptr)
     {
-      if (self->pattern->exec (type_name.c_str (), 0, NULL, 0) != 0)
+      if (self->pattern->exec (name, 0, NULL, 0) != 0)
...

Before the commit, we have:
- type_name == "my_exception"
- canon = ""
and the !type_name.empty () test succeeds, and gdb executes the
self->pattern->exec call.

After the commit, we have:
- type_name == "my_exception"
- canon == NULL
- name == NULL
and the name != nullptr test fails, and gdb doesn't execute the
self->pattern->exec call.

Fix this by inverting the condition for the calculation of name:
...
-      name = (canon == nullptr
+      name = (canon != nullptr
...

Build and tested on x86_64-linux.

4f7bc5edbd Don't re-process a DIE in read_lexical_block_scope
A customer reported a crash in the DWARF reader.

Investigation showed that the crash occurred in an unusual scenario: a
function was lexically scoped within some other function -- but the
inner function inlined the outer function and referred to its DIE via
DW_AT_abstract_origin.  With the executable in question,
inherit_abstract_dies could eventually call read_lexical_block_scope,
which in turn could recurse into process_die, to process a DIE that
was already being read, triggering an assert.

This came up once before; see:

https://www.sourceware.org/ml/gdb-patches/2014-02/msg00652.html

However, in this case, I don't have an easy way to reproduce.  So,
there is no test case.

I did experiment with the failing executable.  This patch fixes the
bug and doesn't seem to cause other issues.  For example, I can still
set breakpoints on the relevant functions.

8be4b118a9 More C++-ification for struct display
This changes displays to have a constructor, use bool and std::string,
and to be stored using std::vector.  The ALL_DISPLAYS and
ALL_DISPLAYS_SAFE macros are removed.  While internal iteration is
still done via map_display_numbers, this is updated to use a
function_view.  These changes simplify the code somewhat; for example,
free_display can now be removed in favor of ordinary destruction.

a1fd1ac9de Remove ALL_SO_LIBS and so_list_head
This patch started as an attempt to replace ALL_SO_LIBS with an
ordinary C++ iterator.  However, then I tripped over the so_list_head
define again, and decided to remove it as well.
