-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".
-
-nodebug.exp--test printing variables.
-
-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:
-1. Print variables from the core file (data and stack), and text
-(from the exec file). This tests whether the corefile sections are
-mapped to the right addresses.
-2. Test what happens when we get a new exec file without explicitly
-getting rid of the core file (we at least must avoid core dumps and such).
-3. Test backtrace in corefile.exp.
-4. 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. There is a list of test cases in main.c in the gdb
-source. Test these with 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.
-
-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 module__2do (for example) in a C program does not get
-demangled.
-
-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 "handle all nostop". Right now this is buggy--it (a) prints "?"
-for "Unknown signal", (b) prints signal zero (bug or feature?), (c)
-dumps core when it is done.
-
-Test that the copyright year in the startup message matches the
-current year (would produce a single spurious FAIL on old GDB's, but
-probably still a good idea).
-
-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).
