gdb/testsuite/TODO

   1 The highest priority item is not on this list: Fix bugs in the
   2 existing testsuite, fix the GDB/compiler/shell/etc bugs which it
   3 detects (particularly when they are hard to XFAIL), make it run
   4 reliably without unexpected failures on the "standard" machines, etc.
   5 This list exists largely as "tests we can add when we are ready to
   6 risk destabilizing it again".
   7
   8 return.exp--reenable test (there is nothing known to be wrong with the
   9 test, but it hasn't been tried on a wide range of architectures).
  10
  11 nodebug.exp--test printing variables.
  12
  13 Test printing of structures passed by value, for the 7th, 8th, and 9th
  14 arguments (PR 1714).  Test printing structure arguments of
  15 2,4,6,8,12,16,and 20 bytes.  Same for structure return of all those
  16 sizes ("return", "finish", and call function).
  17
  18 Get crossload tests to use --with-targets and reenable them.
  19
  20 corefile.exp:
  21 1.  Print variables from the core file (data and stack), and text
  22 (from the exec file).  This tests whether the corefile sections are
  23 mapped to the right addresses.
  24 2.  Test what happens when we get a new exec file without explicitly
  25 getting rid of the core file (we at least must avoid core dumps and such).
  26 3.  Test backtrace in corefile.exp.
  27 4.  Test ability to run program when there is a core target, then go
  28 back to the core file when the program exits.
  29
  30 Test handling of floating point variables
  31 1.  float, double, or long double
  32 2.  in register or saved register or memory.  Also the case where a
  33 double is in two float registers and only one of them is saved.
  34 3.  print them or set them
  35 4.  (Alpha) integer (32 or 64 bit) in floating point register.
  36
  37 Print registers--"p $r5", "p sizeof ($r5)".  Test that they print
  38 appropriately (integer registers in decimal, registers which always
  39 contain addresses (pc, probably sp and fp, maybe others) in hex,
  40 floating point).
  41
  42 Test "info line" with all kinds of linespecs.  Test that the last line
  43 of the file works right.
  44
  45 weird.exp--test that unrecognized cross-reference types or
  46 unrecognized visibility or virtual characters get skipped properly
  47 (see stabs.texinfo).
  48
  49 Test C++ nested types (especially if PR 1954 is fixed; even if not
  50 *some* things already should work even in the presence of nested
  51 types).  Test classes nested more than 9 levels deep (g++ mangles
  52 these differently) (both a demangle test and some tests which also
  53 test the compiler).  Test calling a method of a class nested more than
  54 9 levels (for gdb_mangle_name and demangling).
  55
  56 Test printing complex types, including functions, pointers to arrays
  57 of pointers of functions, functions which return pointers to
  58 functions, etc.
  59
  60 Test GDB expressions--test all operators (and overloaded operators for
  61 C++).  Test integer constants which are signed or unsigned int, long,
  62 or long long.  Test detection of overflow of an integer constant.
  63 Here are a few integer constants to test (test they get the right
  64 types): 5, 5LL, 5LuL, 5L6u (invalid), 5LU.  Maybe things like
  65 0x12345678, 0x87654321, etc., but their types depend on sizes of int,
  66 long, etc.
  67
  68 Test that printing const-qualified versions of various types works.
  69 In particular, on the sparc and probably other machines, "double" is
  70 handled differently from most types because it requires more alignment
  71 and thus goes in a different section (there is a gcc 2.4.5 bug with
  72 "const double" on sparc).
  73
  74 Test that GDB's "source" command works and that things work if stdin
  75 is redirected (to a file or a pipe).  Test user defined command.  Run
  76 an inferior each of these ways (to test that inflow.c works).  Test
  77 that GDB works if the last line of stdin or a source'd file lacks a
  78 newline.
  79
  80 Test that module__2do (for example) in a C program does not get
  81 demangled.
  82
  83 Test that unmatched single quotes produce error messages, both in
  84 expressions and linespecs.
  85
  86 Test "cd".  "foo/bar/.." should get simplified to "foo".  "/../.."
  87 should not get simplified (for Mach).  "/.." should not get simplified
  88 (for other networked OSes; POSIX.1 section B.2.3.7).  All these
  89 examples should continue to work with trailing slashes.
  90
  91 Test scoping; here is a start
  92  1      int i=2;
  93  2      int j=3;
  94  3      main()
  95  4      {
  96  5          int i;
  97  6          for (i=600; i>0; i--)
  98  7              print_line(i);
  99  8      }
 100  9
 101 10      print_line(i)
 102 11          int i;
 103 12      {
 104 13          h();
 105 14          printf("%d\n",i);
 106 15      }
 107 16
 108 17      h()
 109 18      {
 110 19          printf("In h...");
 111 20      }
 112 Set a breakpoint in h, and print i, print_line::i, and main::i.  Set a
 113 breakpoint in main (or don't run the program), and test that
 114 print_line::i is an error.  But if i were static, "p main::i" should
 115 work even if the program is not being run.
 116
 117 Write a test for the reentracy bug with rs6000_struct_return_address
 118 in rs6000-tdep.c.
 119
 120 Test "return" from dummy frames.
 121
 122 FORTRAN common blocks (a.out and xcoff--weird.exp has the start of
 123 one but it is not quite right as of 19 Nov 1993).
 124
 125 Test that "x" command sets $_ and $__.  Test $_ in general.
 126
 127 Given `char abc[] = "abc\0def";' test "x/s abc" followed by "x/s"
 128 (should display "abc" followed by "def").  Test this works with no
 129 error message even if this is the last thing in the section (tests
 130 that val_print_string ignores an error if the error occurs after the
 131 '\0').
 132
 133 Test ability to process NMAGIC a.out files.
 134
 135 Test shared libraries:  "next" over printf, "step" into a function in
 136 a shared library which has line number info, breakpoint in a function
 137 in a shared library (either before or after the program is run and the
 138 shared libraries are loaded--also maybe write a test where the PLT
 139 will be in an unloaded state even though the shared library is loaded).
 140
 141 If there are two breakpoints in the same place, and exactly one of
 142 them has its condition true, test that the correct breakpoint gets
 143 printed.
 144
 145 Test "jump" including jump to a breakpoint (the latter will need an
 146 xfail for UDI and probably VxWorks (PR 1786 for vxworks; PR 2416
 147 contains some info for 29k).
 148
 149 Set a watchpoint on a local variable (to be interesting, make a few
 150 calls, to be more interesting, make a recursive call).  Test that it
 151 gets disabled when leaving that scope.
 152
 153 Test calling a function, hitting a breakpoint in the called function,
 154 calling another function, and hitting a breakpoint.  Test backtrace
 155 works in the presence of multiple dummy frames.  Test that "continue"
 156 will get you out of the inner called function, and "continue" again
 157 will get you back to where you were when you called the first one.
 158
 159 Test special longjmp handling in wait_for_inferior (need to figure out
 160 in detail what the proper behavior in each case is).  Test longjmp to
 161 a place where there is a breakpoint (such that
 162 BPSTAT_WHAT_CLEAR_LONGJMP_RESUME_SINGLE happens).  In general, test
 163 interactions between longjmp and watchpoints, breakpoints, stepping,
 164 call function, etc.
 165
 166 Test jumping right past a breakpoint (the case where wait_for_inferior
 167 passes not_a_breakpoint to bpstat_stop_status).  Might already be
 168 tested by some of the sun3 tests.  Probably want a .s test to avoid
 169 compiler dependencies.
 170
 171 Test more obscure wait_for_inferior cases, expanding on the tests in
 172 watchpoint.exp, signals.exp, etc.
 173
 174 Test that the copyright year in the startup message matches the
 175 current year (would produce a single spurious FAIL on old GDB's, but
 176 probably still a good idea).
