However, filename searching doesn't (and +probably shouldn't) guarantee this. The fix is to walk upward to find +the outermost CU. + +A new test case is included.

There, +psym_map_symtabs_matching_filename is gone, replaced by +psymbol_functions::expand_symtabs_matching.

It isn't great to lose that errors like +that, though. I've been thinking about how to avoid it, and I came up +with this patch. + +The idea here is to make scoped_restore_current_thread's dtor do as +little as possible, to avoid any work that might throw in the first +place. And to do that, instead of having the dtor call +restore_selected_frame, which re-finds the previously selected frame, +just record the frame_id/level of the desired selected frame, and have +get_selected_frame find the frame the next time it is called. In +effect, this implements most of Cagney's suggestion, here: + + /* On demand, create the selected frame and then return it.

When MESSAGE is non-NULL, use it for the error message, + otherwize use a generic error message. */ + /* FIXME: cagney/2002-11-28: At present, when there is no selected + frame, this function always returns the current (inner most) frame. + It should instead, when a thread has previously had its frame + selected (but not resumed) and the frame cache invalidated, find + and then return that thread's previously selected frame. */ + extern struct frame_info *get_selected_frame (const char *message); + +The only thing missing to fully implement that would be to make +reinit_frame_cache just clear selected_frame instead of calling +select_frame(NULL), and the call select_frame(NULL) explicitly in the +places where we really wanted reinit_frame_cache to go back to the +current frame too. That can done separately, though, I'm not +proposing to do that in this patch. + +Note that this patch renames restore_selected_frame to +lookup_selected_frame, and adds a new restore_selected_frame function +that doesn't throw, to be paired with the also-new save_selected_frame +function. + +There's a restore_selected_frame function in infrun.c that I think can +be replaced by the new one in frame.c. + +Also done in this patch is make the get_selected_frame's parameter be +optional, so that we don't have to pass down nullptr explicitly all +over the place. + +lookup_selected_frame should really move from thread.c to frame.c, but +I didn't do that here, just to avoid churn in the patch while it +collects comments. I did make it extern and declared it in frame.h +already, preparing for the move.

More +details on this below. + +This patch rewrites two areas of GDB's Fortran support, the code to +extract an array slice, and the code to print an array. + +After this commit a user can, from the GDB prompt, ask for a slice of +a Fortran array and should get the correct result back. Slices can +(optionally) have the lower bound, upper bound, and a stride +specified. Slices can also have a negative stride. + +Fortran has the concept of repacking array slices. Within a compiled +Fortran program if a user passes a non-contiguous array slice to a +function then the compiler may have to repack the slice, this involves +copying the elements of the slice to a new area of memory before the +call, and copying the elements back to the original array after the +call. Whether repacking occurs will depend on which version of +Fortran is being used, and what type of function is being called. + +This commit adds support for both packed, and unpacked array slicing, +with the default being unpacked. + +With an unpacked array slice, when the user asks for a slice of an +array GDB creates a new type that accurately describes where the +elements of the slice can be found within the original array, a +value of this type is then returned to the user. The address of an +element within the slice will be equal to the address of an element +within the original array. + +A user can choose to select packed array slices instead using: + + (gdb) set fortran repack-array-slices on|off + (gdb) show fortran repack-array-slices + +With packed array slices GDB creates a new type that reflects how the +elements of the slice would look if they were laid out in contiguous +memory, allocates a value of this type, and then fetches the elements +from the original array and places then into the contents buffer of +the new value. + +One benefit of using packed slices over unpacked slices is the memory +usage, taking a small slice of N elements from a large array will +require (in GDB) N * ELEMENT_SIZE bytes of memory, while an unpacked +array will also include all of the "padding" between the +non-contiguous elements. There are new tests added that highlight +this difference. + +There is also a new debugging flag added with this commit that +introduces these commands: + + (gdb) set debug fortran-array-slicing on|off + (gdb) show debug fortran-array-slicing + +This prints information about how the array slices are being built. + +As both the repacking, and the array printing requires GDB to walk +through a multi-dimensional Fortran array visiting each element, this +commit adds the file f-array-walk.h, which introduces some +infrastructure to support this process. This means the array printing +code in f-valprint.c is significantly reduced. + +The only slight issue with this commit is the "rather big hack" that I +mentioned above. This hack allows us to handle one specific case, +array slices with negative strides. This is something that I don't +believe the current GDB value contents model will allow us to +correctly handle, and rather than rewrite the value contents code +right now, I'm hoping to slip this hack in as a work around. + +The problem is that, as I see it, the current value contents model +assumes that an object base address will be the lowest address within +that object, and that the contents of the object start at this base +address and occupy the TYPE_LENGTH bytes after that. + +( We do have the embedded_offset, which is used for C++ sub-classes, +such that an object can start at some offset from the content buffer, +however, the assumption that the object then occupies the next +TYPE_LENGTH bytes is still true within GDB. ) + +The problem is that Fortran arrays with a negative stride don't follow +this pattern. In this case the base address of the object points to +the element with the highest address, the contents of the array then +start at some offset _before_ the base address, and proceed for one +element _past_ the base address. + +As the stride for such an array would be negative then, in theory the +TYPE_LENGTH for this type would also be negative. However, in many +places a value in GDB will degrade to a pointer + length, and the +length almost always comes from the TYPE_LENGTH. + +It is my belief that in order to correctly model this case the value +content handling of GDB will need to be reworked to split apart the +value's content buffer (which is a block of memory with a length), and +the object's in memory base address and length, which could be +negative. + +Things are further complicated because arrays with negative strides +like this are always dynamic types. When a value has a dynamic type +and its base address needs resolving we actually store the address of +the object within the resolved dynamic type, not within the value +object itself. + +In short I don't currently see an easy path to cleanly support this +situation within GDB. And so I believe that leaves two options, +either add a work around, or catch cases where the user tries to make +use of a negative stride, or access an array with a negative stride, +and throw an error. + +This patch currently goes with adding a work around, which is that +when we resolve a dynamic Fortran array type, if the stride is +negative, then we adjust the base address to point to the lowest +address required by the array. The printing and slicing code is aware +of this adjustment and will correctly slice and print Fortran arrays. + +Where this hack will show through to the user is if they ask for the +address of an array in their program with a negative array stride, the +address they get from GDB will not match the address that would be +computed within the Fortran program. + +gdb/ChangeLog: + + * Makefile.in (HFILES_NO_SRCDIR): Add f-array-walker.h. + * NEWS: Mention new options. + * f-array-walker.h: New file. + * f-lang.c: Include 'gdbcmd.h' and 'f-array-walker.h'. + (repack_array_slices): New static global. + (show_repack_array_slices): New function. + (fortran_array_slicing_debug): New static global. + (show_fortran_array_slicing_debug): New function. + (value_f90_subarray): Delete. + (skip_undetermined_arglist): Delete. + (class fortran_array_repacker_base_impl): New class. + (class fortran_lazy_array_repacker_impl): New class. + (class fortran_array_repacker_impl): New class. + (fortran_value_subarray): Complete rewrite. + (set_fortran_list): New static global. + (show_fortran_list): Likewise. + (_initialize_f_language): Register new commands. + (fortran_adjust_dynamic_array_base_address_hack): New function. + * f-lang.h (fortran_adjust_dynamic_array_base_address_hack): + Declare. + * f-valprint.c: Include 'f-array-walker.h'. + (class fortran_array_printer_impl): New class. + (f77_print_array_1): Delete. + (f77_print_array): Delete. + (fortran_print_array): New. + (f_value_print_inner): Update to call fortran_print_array. + * gdbtypes.c: Include 'f-lang.h'. + (resolve_dynamic_type_internal): Call + fortran_adjust_dynamic_array_base_address_hack. + +gdb/testsuite/ChangeLog: + + * gdb.fortran/array-slices-bad.exp: New file. + * gdb.fortran/array-slices-bad.f90: New file. + * gdb.fortran/array-slices-sub-slices.exp: New file. + * gdb.fortran/array-slices-sub-slices.f90: New file. + * gdb.fortran/array-slices.exp: Rewrite tests. + * gdb.fortran/array-slices.f90: Rewrite tests. + * gdb.fortran/vla-sizeof.exp: Correct expected results. + +gdb/doc/ChangeLog: + + * gdb.texinfo (Debugging Output): Document 'set/show debug + fortran-array-slicing'. + (Special Fortran Commands): Document 'set/show fortran + repack-array-slices'. + +diff --git a/gdb/Makefile.in b/gdb/Makefile.in +--- a/gdb/Makefile.in ++++ b/gdb/Makefile.in +@@ -1268,6 +1268,7 @@ HFILES_NO_SRCDIR = \ + expression.h \ + extension.h \ + extension-priv.h \ ++ f-array-walker.h \ + f-lang.h \ + fbsd-nat.h \ + fbsd-tdep.h \ +diff --git a/gdb/NEWS b/gdb/NEWS +--- a/gdb/NEWS ++++ b/gdb/NEWS +@@ -111,6 +111,19 @@ maintenance print core-file-backed-mappings + Prints file-backed mappings loaded from a core file's note section. + Output is expected to be similar to that of "info proc mappings". + ++set debug fortran-array-slicing on|off ++show debug fortran-array-slicing ++ Print debugging when taking slices of Fortran arrays. ++ ++set fortran repack-array-slices on|off ++show fortran repack-array-slices ++ When taking slices from Fortran arrays and strings, if the slice is ++ non-contiguous within the original value then, when this option is ++ on, the new value will be repacked into a single contiguous value. ++ When this option is off, then the value returned will consist of a ++ descriptor that describes the slice within the memory of the ++ original parent value. ++ + * Changed commands + + alias [-a] [--] ALIAS = COMMAND [DEFAULT-ARGS...] +diff --git a/gdb/doc/gdb.texinfo b/gdb/doc/gdb.texinfo +--- a/gdb/doc/gdb.texinfo ++++ b/gdb/doc/gdb.texinfo +@@ -16919,6 +16919,29 @@ This command prints the values contained in the Fortran @code{COMMON} + block whose name is @var{common-name}.

For each shared library (if "set auto-solib-add" is on), it +reads its symbols and calls the "new_objfile" observable. + +The libthread-db code monitors this observable, and if it sees an +objfile named somewhat like "libpthread.so" go by, it tries to load +libthread_db.so in the GDB process itself. libthread_db knows how to +navigate libpthread's data structures to get information about the +existing threads. + +To locate these data structures, libthread_db calls ps_pglobal_lookup +(implemented in proc-service.c), passing in a symbol name and expecting +an address in return. + +Before glibc 2.33, libthread_db always asked for symbols found in +libpthread. There was no ordering problem: since we were always trying +to load libthread_db in reaction to processing libpthread (and reading +in its symbols) and libthread_db only asked symbols from libpthread, the +requested symbols could always be found.

So when +loading libthread_db in reaction to processing libpthread, and +libthread_db requests the symbol that is from ld-linux, GDB is not yet +able to supply it. + +That problematic symbol lookup
