The highest priority item is not on this list: Fix bugs in the

existing testsuite, fix the GDB/compiler/shell/etc bugs which it

detects (particularly when they are hard to XFAIL), make it run

reliably without unexpected failures on the "standard" machines, etc.

This list exists largely as "tests we can add when we are ready to

risk destabilizing it again".

There are some tests which are only run on some platforms because they

have not been tested on more platforms.  Enable them and fix any

problems.  A partial list: recurse.exp, watchpoint.exp

(test_watchpoint_triggered_in_syscall, test_complex_watchpoint).

Test printing of structures passed by value, for the 7th, 8th, and 9th

arguments (PR 1714).  Test printing structure arguments of

2,4,6,8,12,16,and 20 bytes.  Same for structure return of all those

sizes ("return", "finish", and call function).

Get crossload tests to use --enable-targets and reenable them.

corefile.exp:

Test ability to run program when there is a core target, then go

back to the core file when the program exits.

Test handling of floating point variables

1.  float, double, or long double

2.  in register or saved register or memory.  Also the case where a

double is in two float registers and only one of them is saved.

3.  print them or set them

4.  (Alpha) integer (32 or 64 bit) in floating point register.

Print registers--"p $r5", "p sizeof ($r5)".  Test that they print

appropriately (integer registers in decimal, registers which always

contain addresses (pc, probably sp and fp, maybe others) in hex,

floating point).

Test completer.  Test that it completes a variety of things correctly

(see the list of test cases in main.c in the gdb source).  Test TAB,

M-?, and the "complete" command.

Test "info line" with all kinds of linespecs.  Test that the last line

of the file works right.

weird.exp--test that unrecognized cross-reference types or

unrecognized visibility or virtual characters get skipped properly

(see stabs.texinfo).

Test C++ nested types (especially if PR 1954 is fixed; even if not

*some* things already should work even in the presence of nested

types).  Test classes nested more than 9 levels deep (g++ mangles

these differently) (both a demangle test and some tests which also

test the compiler).  Test calling a method of a class nested more than

9 levels (for gdb_mangle_name and demangling).

Test static member functions (C++).  Test that "ptype" shows them

correctly, both before and after they have been converted from stub

methods.  Test that we can call them.

Test printing complicated types, including functions, pointers to

arrays of pointers of functions, functions which return pointers to

functions, etc.

printcmd.exp--test printing enum values.  Test printing an enum

variable whose value is out of range.  Test "p (int)enum_var", "p/x

enum_var".  Test that in something like "enum {FOO, LAST_THING=FOO}"

we print FOO, not LAST_THING.

Test GDB expressions--test all operators (and overloaded operators for

C++).  Test integer constants which are signed or unsigned int, long,

or long long.  Test detection of overflow of an integer constant.

Here are a few integer constants to test (test they get the right

types): 5, 5LL, 5LuL, 5L6u (invalid), 5LU.  Maybe things like

0x12345678, 0x87654321, etc., but their types depend on sizes of int,

long, etc.

Test that printing const-qualified versions of various types works.

In particular, on the sparc and probably other machines, "double" is

handled differently from most types because it requires more alignment

and thus goes in a different section (there is a gcc 2.4.5 bug with

"const double" on sparc).

Test that GDB's "source" command works and that things work if stdin

is redirected (to a file or a pipe).  Test user defined command.  Run

an inferior each of these ways (to test that inflow.c works).  Test

that GDB works if the last line of stdin or a source'd file lacks a

newline.

Test that unmatched single quotes produce error messages, both in

expressions and linespecs.

Test "cd".  "foo/bar/.." should get simplified to "foo".  "/../.."

should not get simplified (for Mach).  "/.." should not get simplified

(for other networked OSes; POSIX.1 section B.2.3.7).  All these

examples should continue to work with trailing slashes.

Test scoping; here is a start

 1      int i=2;

 2      int j=3;

 3      main()

 4      {

 5          int i;

 6          for (i=600; i>0; i--)

 7              print_line(i);

 8      }

 9

10      print_line(i)

11          int i;

12      {

13          h();

14          printf("%d\n",i);

15      }

16

17      h()

18      {

19          printf("In h...");

20      }

Set a breakpoint in h, and print i, print_line::i, and main::i.  Set a

breakpoint in main (or don't run the program), and test that

print_line::i is an error.  But if i were static, "p main::i" should

work even if the program is not being run.

Write a test for the reentracy bug with rs6000_struct_return_address

in rs6000-tdep.c.

Test "return" from dummy frames.  Test "return" from non-innermost

frame.  Test that "return" from a non-innermost frame restores

registers which are saved not in that frame but in a frame more inner

(I believe this currently works on few if any architectures).

FORTRAN common blocks (a.out and xcoff--weird.exp has the start of

one but it is not quite right as of 19 Nov 1993).

Test that "x" command sets $_ and $__.  Test $_ in general.

Test that "p/a" works when given addresses in text, data, and bss

segments.  Test that it works if program is compiled with or without

-g.  Test that it works if preceding symbol is static or if it is

extern.

Given `char abc[] = "abc\0def";' test "x/s abc" followed by "x/s"

(should display "abc" followed by "def").  Test this works with no

error message even if this is the last thing in the section (tests

that val_print_string ignores an error if the error occurs after the

'\0').

Test ability to process NMAGIC a.out files.

Test shared libraries:  "next" over printf, "step" into a function in

a shared library which has line number info, breakpoint in a function

in a shared library (either before or after the program is run and the

shared libraries are loaded--also maybe write a test where the PLT

will be in an unloaded state even though the shared library is loaded).

If there are two breakpoints in the same place, and exactly one of

them has its condition true, test that the correct breakpoint gets

printed.

Test "jump" including jump to a breakpoint (the latter will need an

xfail for UDI and probably VxWorks (PR 1786 for vxworks; PR 2416

contains some info for 29k).

Set a watchpoint on a local variable (to be interesting, make a few

calls, to be more interesting, make a recursive call).  Test that it

gets disabled when leaving that scope.

Test calling a function, hitting a breakpoint in the called function,

calling another function, and hitting a breakpoint.  Test backtrace

works in the presence of multiple dummy frames.  Test that "continue"

will get you out of the inner called function, and "continue" again

will get you back to where you were when you called the first one.

Test special longjmp handling in wait_for_inferior (need to figure out

in detail what the proper behavior in each case is).  Test longjmp to

a place where there is a breakpoint (such that

BPSTAT_WHAT_CLEAR_LONGJMP_RESUME_SINGLE happens).  In general, test

interactions between longjmp and watchpoints, breakpoints, stepping,

call function, etc.

Test jumping right past a breakpoint (the case where wait_for_inferior

passes not_a_breakpoint to bpstat_stop_status).  Might already be

tested by some of the sun3 tests.  Probably want a .s test to avoid

compiler dependencies.

Test more obscure wait_for_inferior cases, expanding on the tests in

watchpoint.exp, signals.exp, etc.

Test stepping into functions which are one line long and functions

which are on line 1 of the source file. (there is a class of bugs in

which gdb doesn't find the line number information, and thus doesn't

step into the function).

Test that prologue recognition, backtrace, printing locals, etc.,

still work in the presence of large frames (the point being that at

some point immediate fields in RISC instructions will overflow and

prologues will need to look different.  For sparc, the immediate field

is 13 bits (signed), so I believe the threshold would be 4K bytes in a

frame).
