(Changes from Daniel Berlin, with revisions by Jim Blandy.) Abstract out operations specific to particular C++ ABI's, and invoke them through a function table. This removes the C++ ABI dependencies scattered throughout the code, and allows us to cleanly add support for new C++ ABI's. * cp-abi.h, cp-abi.h, gnu-v2-abi.c, hpacc-abi.c: New files. * c-typeprint.c, c-valprint.c, dbxread.c, eval.c, gdbtypes.c, jv-typeprint.c, linespec.c, symtab.c, typeprint.c, valops.c: #include "cp-abi.h". These files all use functions now declared there. * symtab.h (OPNAME_PREFIX_P, VTBL_PREFIX_P, DESTRUCTOR_PREFIX_P): Deleted. These services are now provided by functions declared in cp-abi.h. * value.h (value_rtti_type, value_virtual_fn_field): Same. * values.c (value_virtual_fn_field): Same, for this definition. * valops.c (value_rtti_type): Same. * c-typeprint.c (c_type_print_base): Use the functions from "cp-abi.h", instead of the old macros, or hard-coded ABI-specific tests. * dbxread.c (record_minimal_symbol): Same. * gdbtypes.c (get_destructor_fn_field, virtual_base_index, virtual_base_index_skip_primaries): Same. * jv-typeprint.c (java_type_print_base): Same. * linespec.c (find_methods, decode_line_1): Same. * symtab.c (gdb_mangle_name): Same. * Makefile.in (SFILES): Add the new .c files mentioned above. (cp_abi_h): New variable. (COMMON_OBS): Add gnu-v2-abi.o, hpacc-abi.o, and cp-abi.o. (cp-abi.o, gnu-v2-abi.o, hpacc-abi.o): New targets. (c-typeprint.o, c-valprint.o, dbxread.o, eval.o, gdbtypes.o, jv-typeprint.o, symtab.o, linespec.o, typeprint.o, valops.o): Add dependency on $(cp_abi_h).

Implement pahole-like 'ptype /o' option This commit implements the pahole-like '/o' option for 'ptype', which prints the offsets and sizes of struct fields, reporting whenever there is a hole found. The output is heavily based on pahole(1), with a few modifications here and there to adjust it to our reality. Here's an example: /* offset | size */ type = struct wer : public tuv { public: /* 32 | 24 */ struct tyu { /* 32:31 | 4 */ int a1 : 1; /* 32:28 | 4 */ int a2 : 3; /* 32: 5 | 4 */ int a3 : 23; /* 35: 3 | 1 */ char a4 : 2; /* XXX 3-bit hole */ /* XXX 4-byte hole */ /* 40 | 8 */ int64_t a5; /* 48:27 | 4 */ int a6 : 5; /* 48:56 | 8 */ int64_t a7 : 3; /* total size (bytes): 24 */ } a1; /* total size (bytes): 56 */ } A big part of this patch handles the formatting logic of 'ptype', which is a bit messy. The code to handle bitfield offsets, however, took some time to craft. My thanks to Pedro Alves for figuring things out and pointing me to the right direction, as well as coming up with a way to inspect the layout of structs with bitfields (see testcase for comments). After many discussions both on IRC and at the mailing list, I tried to implement printing vtables and inherited classes.

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue. Upshot: the test suite now has stack and queue data structures that may be used by test writers. gdb/ChangeLog * NEWS (New commands): Mention set/show print type nested-type-limit. * c-typeprint.c (c_type_print_base): Print out nested types. * dwarf2read.c (struct typedef_field_list): Rename to ...

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types).

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue.

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue. Upshot: the test suite now has stack and queue data structures that may be used by test writers. gdb/ChangeLog * NEWS (New commands): Mention set/show print type nested-type-limit. * c-typeprint.c (c_type_print_base): Print out nested types. * dwarf2read.c (struct typedef_field_list): Rename to ...

C++-ify typedef hash This changes the typedef_hash_table structure to be a C++ class. It adds constructors and destructors and changes some functions to be methods of the class. Then it changes the various users of this class to adapt. This allows for the removal of some cleanups.

Add casts to memory allocation related calls Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script.

C++-ify typedef hash This changes the typedef_hash_table structure to be a C++ class. It adds constructors and destructors and changes some functions to be methods of the class. Then it changes the various users of this class to adapt. This allows for the removal of some cleanups. Regression tested by the buildbot. gdb/ChangeLog 2018-03-27 Tom Tromey <tom@tromey.com> * typeprint.h (struct type_print_options) <local_typedefs, global_typedefs>: Remove "struct" keyword.

Add casts to memory allocation related calls Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue. Upshot: the test suite now has stack and queue data structures that may be used by test writers. gdb/ChangeLog * NEWS (New commands): Mention set/show print type nested-type-limit. * c-typeprint.c (c_type_print_base): Print out nested types. * dwarf2read.c (struct typedef_field_list): Rename to ...

C++-ify typedef hash This changes the typedef_hash_table structure to be a C++ class. It adds constructors and destructors and changes some functions to be methods of the class.

/* Print TYPE to a string, returning it. The caller is responsible for
freeing the string. */
Use ui_file_as_string throughout more This replaces most of the remaining ui_file_xstrdup calls with ui_file_as_string calls. Whenever a call was replaced, that led to a cascade of other necessary adjustments throughout, to make the code use std::string instead of raw pointers. And then whenever I added a std::string as member of a struct, I needed to adjust allocation/destruction of said struct to use new/delete instead of xmalloc/xfree. The stopping point was once gdb built again. These doesn't seem to be a way to reasonably split this out further. Maybe-not-obvious changes: - demangle_for_lookup returns a cleanup today. To get rid of that, and avoid unnecessary string dupping/copying, this introduces a demangle_result_storage type that the caller instantiates and passes to demangle_for_lookup. - Many methods returned a "char *" to indicate that the caller owns the memory and must free it. Those are switched to return a std::string instead. Methods that return a "view" into some internal string return a "const char *" instead. I.e., we only copy/allocate when necessary. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception. Now an exception value. <mask>: Delete field. (exceptions_state_mc_init): Remove all parameters. Adjust. (exceptions_state_mc): No longer pop the catcher here.

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy This patch starts from the desire to eliminate make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file & friends a real C++ class hierarchy, and switches temporary ui_file-like objects to stack-based allocation. - mem_fileopen -> string_file mem_fileopen is replaced with a new string_file class that is treated as a value class created on the stack. This alone eliminates most make_cleanup_ui_file_delete calls, and, simplifies code a whole lot (diffstat shows around 1k loc dropped.) string_file's internal buffer is a std::string, thus the "string" in the name. This simplifies the implementation much, compared to mem_fileopen, which managed growing its internal buffer manually. - ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone The new string_file class has a string() method that provides direct writable access to the internal std::string buffer. This replaced ui_file_as_string, which forced a copy of the same data the stream had inside. With direct access via a writable reference, we can instead move the string out of the string_stream, avoiding deep string copying. Related, ui_file_xstrdup calls are replaced with xstrdup'ping the stream's string, and ui_file_obsavestring is replaced by obstack_copy0. With all those out of the way, getting rid of the weird ui_file_put mechanism was possible. - New ui_file::printf, ui_file::puts, etc. methods These simplify / clarify client code. I considered splitting client-code changes, like these, e.g.: - stb = mem_fileopen (); - fprintf_unfiltered (stb, "%s%s%s", - _("The valid values are:\n"), - regdesc, - _("The default is \"std\".")); + string_file stb; + stb.printf ("%s%s%s", + _("The valid values are:\n"), + regdesc, + _("The default is \"std\".")); In two steps, with the first step leaving fprintf_unfiltered (etc.) calls in place, and only afterwards do a pass to change all those to call stb.printf etc.. I didn't do that split, because (when I tried), it turned out to be pointless make-work: the first pass would have to touch the fprintf_unfiltered line anyway, to replace "stb" with "&stb". - gdb_fopen replaced with stack-based objects This avoids the need for cleanups or unique_ptr's. I.e., this: struct ui_file *file = gdb_fopen (filename, "w"); if (filename == NULL) perror_with_name (filename); cleanups = make_cleanup_ui_file_delete (file); // use file. do_cleanups (cleanups); is replaced with this: stdio_file file; if (!file.open (filename, "w")) perror_with_name (filename); // use file. - odd contorsions in null_file_write / null_file_fputs around when to call to_fputs / to_write eliminated. - Global null_stream object A few places that were allocating a ui_file in order to print to "nowhere" are adjusted to instead refer to a new 'null_stream' global stream. - TUI's tui_sfileopen eliminated. TUI's ui_file much simplified The TUI's ui_file was serving a dual purpose. It supported being used as string buffer, and supported being backed by a stdio FILE. The string buffer part is gone, replaced by using of string_file. The 'FILE *' support is now much simplified, by making the TUI's ui_file inherit from stdio_file. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * ada-lang.c (type_as_string): Use string_file. * ada-valprint.c (ada_print_floating): Use string_file. * ada-varobj.c (ada_varobj_scalar_image) (ada_varobj_get_value_image): Use string_file. * aix-thread.c (aix_thread_extra_thread_info): Use string_file. * arm-tdep.c (_initialize_arm_tdep): Use string_printf. * breakpoint.c (update_inserted_breakpoint_locations) (insert_breakpoint_locations, reattach_breakpoints) (print_breakpoint_location, print_one_detail_ranged_breakpoint) (print_it_watchpoint): Use string_file.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy This patch starts from the desire to eliminate make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file & friends a real C++ class hierarchy, and switches temporary ui_file-like objects to stack-based allocation. - mem_fileopen -> string_file mem_fileopen is replaced with a new string_file class that is treated as a value class created on the stack. This alone eliminates most make_cleanup_ui_file_delete calls, and, simplifies code a whole lot (diffstat shows around 1k loc dropped.) string_file's internal buffer is a std::string, thus the "string" in the name. This simplifies the implementation much, compared to mem_fileopen, which managed growing its internal buffer manually. - ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone The new string_file class has a string() method that provides direct writable access to the internal std::string buffer. This replaced ui_file_as_string, which forced a copy of the same data the stream had inside. With direct access via a writable reference, we can instead move the string out of the string_stream, avoiding deep string copying. Related, ui_file_xstrdup calls are replaced with xstrdup'ping the stream's string, and ui_file_obsavestring is replaced by obstack_copy0. With all those out of the way, getting rid of the weird ui_file_put mechanism was possible. - New ui_file::printf, ui_file::puts, etc. methods These simplify / clarify client code. I considered splitting client-code changes, like these, e.g.: - stb = mem_fileopen (); - fprintf_unfiltered (stb, "%s%s%s", - _("The valid values are:\n"), - regdesc, - _("The default is \"std\".")); + string_file stb; + stb.printf ("%s%s%s", + _("The valid values are:\n"), + regdesc, + _("The default is \"std\".")); In two steps, with the first step leaving fprintf_unfiltered (etc.) calls in place, and only afterwards do a pass to change all those to call stb.printf etc.. I didn't do that split, because (when I tried), it turned out to be pointless make-work: the first pass would have to touch the fprintf_unfiltered line anyway, to replace "stb" with "&stb". - gdb_fopen replaced with stack-based objects This avoids the need for cleanups or unique_ptr's. I.e., this: struct ui_file *file = gdb_fopen (filename, "w"); if (filename == NULL) perror_with_name (filename); cleanups = make_cleanup_ui_file_delete (file); // use file. do_cleanups (cleanups); is replaced with this: stdio_file file; if (!file.open (filename, "w")) perror_with_name (filename); // use file. - odd contorsions in null_file_write / null_file_fputs around when to call to_fputs / to_write eliminated. - Global null_stream object A few places that were allocating a ui_file in order to print to "nowhere" are adjusted to instead refer to a new 'null_stream' global stream. - TUI's tui_sfileopen eliminated. TUI's ui_file much simplified The TUI's ui_file was serving a dual purpose. It supported being used as string buffer, and supported being backed by a stdio FILE. The string buffer part is gone, replaced by using of string_file. The 'FILE *' support is now much simplified, by making the TUI's ui_file inherit from stdio_file. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * ada-lang.c (type_as_string): Use string_file. * ada-valprint.c (ada_print_floating): Use string_file. * ada-varobj.c (ada_varobj_scalar_image) (ada_varobj_get_value_image): Use string_file. * aix-thread.c (aix_thread_extra_thread_info): Use string_file. * arm-tdep.c (_initialize_arm_tdep): Use string_printf. * breakpoint.c (update_inserted_breakpoint_locations) (insert_breakpoint_locations, reattach_breakpoints) (print_breakpoint_location, print_one_detail_ranged_breakpoint) (print_it_watchpoint): Use string_file.

Stop assuming no-debug-info functions return int The fact that GDB defaults to assuming that functions return int, when it has no debug info for the function has been a recurring source of user confusion. Recently this came up on the errno pretty printer discussions. Shortly after, it came up again on IRC, with someone wondering why does getenv() in GDB return a negative int: (gdb) p getenv("PATH") $1 = -6185 This question (with s/getenv/random-other-C-runtime-function) is a FAQ on IRC. The reason for the above is: (gdb) p getenv $2 = {<text variable, no debug info>} 0x7ffff7751d80 <getenv> (gdb) ptype getenv type = int () ... which means that GDB truncated the 64-bit pointer that is actually returned from getent to 32-bit, and then sign-extended it: (gdb) p /x -6185 $6 = 0xffffe7d7 The workaround is to cast the function to the right type, like: (gdb) p ((char *(*) (const char *)) getenv) ("PATH") $3 = 0x7fffffffe7d7 "/usr/local/bin:/"... IMO, we should do better than this. I see the "assume-int" issue the same way I see printing bogus values for optimized-out variables instead of "<optimized out>" -- I'd much rather that the debugger tells me "I don't know" and tells me how to fix it than showing me bogus misleading results, making me go around tilting at windmills. If GDB prints a signed integer when you're expecting a pointer or aggregate, you at least have some sense that something is off, but consider the case of the function actually returning a 64-bit integer. For example, compile this without debug info: unsigned long long function () { return 0x7fffffffffffffff; } Currently, with pristine GDB, you get: (gdb) p function () $1 = -1 # incorrect (gdb) p /x function () $2 = 0xffffffff # incorrect maybe after spending a few hours debugging you suspect something is wrong with that -1, and do: (gdb) ptype function type = int () and maybe, just maybe, you realize that the function actually returns unsigned long long. And you try to fix it with: (gdb) p /x (unsigned long long) function () $3 = 0xffffffffffffffff # incorrect ... which still produces the wrong result, because GDB simply applied int to unsigned long long conversion. Meaning, it sign-extended the integer that it extracted from the return of the function, to 64-bits. and then maybe, after asking around on IRC, you realize you have to cast the function to a pointer of the right type, and call that. It won't be easy, but after a few missteps, you'll get to it: ..... (gdb) p /x ((unsigned long long(*) ()) function) () $666 = 0x7fffffffffffffff # finally! :-) So to improve on the user experience, this patch does the following (interrelated) things: - makes no-debug-info functions no longer default to "int" as return type. Instead, they're left with NULL/"<unknown return type>" return type. (gdb) ptype getenv type = <unknown return type> () - makes calling a function with unknown return type an error. (gdb) p getenv ("PATH") 'getenv' has unknown return type; cast the call to its declared return type - and then to make it easier to call the function, makes it possible to _only_ cast the return of the function to the right type, instead of having to cast the function to a function pointer: (gdb) p (char *) getenv ("PATH") # now Just Works $3 = 0x7fffffffe7d7 "/usr/local/bin:/"... (gdb) p ((char *(*) (const char *)) getenv) ("PATH") # continues working $4 = 0x7fffffffe7d7 "/usr/local/bin:/"... I.e., it makes GDB default the function's return type to the type of the cast, and the function's parameters to the type of the arguments passed down. After this patch, here's what you'll get for the "unsigned long long" example above: (gdb) p function () 'function' has unknown return type; cast the call to its declared return type (gdb) p /x (unsigned long long) function () $4 = 0x7fffffffffffffff # correct! Note that while with "print" GDB shows the name of the function that has the problem: (gdb) p getenv ("PATH") 'getenv' has unknown return type; cast the call to its declared return type which can by handy in more complicated expressions, "ptype" does not: (gdb) ptype getenv ("PATH") function has unknown return type; cast the call to its declared return type This will be fixed in the next patch. gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp) <TYPE_CODE_FUNC>: Don't handle TYPE_GNU_IFUNC specially here.

Stop assuming no-debug-info variables have type int An earlier commit made GDB no longer assume no-debug-info functions return int. This commit gives the same treatment to variables. Currently, you can end misled by GDB over output like this: (gdb) p var $1 = -1 (gdb) p /x var $2 = 0xffffffff until you realize that GDB is assuming that the variable is an "int", because: (gdb) ptype var type = <data variable, no debug info> You may try to fix it by casting, but that doesn't really help: (gdb) p /x (unsigned long long) var $3 = 0xffffffffffffffff # incorrect ^^ That's incorrect output, because the variable was defined like this: uint64_t var = 0x7fffffffffffffff; ^^ What happened is that with the cast, GDB did an int -> 'unsigned long long' conversion instead of reinterpreting the variable as the cast-to type. To get at the variable properly you have to reinterpret the variable's address manually instead, with either: (gdb) p /x *(unsigned long long *) &var $4 = 0x7fffffffffffffff (gdb) p /x {unsigned long long} &var $5 = 0x7fffffffffffffff After this commit GDB does it for you. This is what you'll get instead: (gdb) p var 'var' has unknown type; cast it to its declared type (gdb) p /x (unsigned long long) var $1 = 0x7fffffffffffffff As in the functions patch, the "compile" machinery doesn't currently have the cast-to type handy, so it continues assuming no-debug variables have int type, though now at least it warns. The change to gdb.cp/m-static.exp deserves an explanation: - gdb_test "print 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \ + gdb_test "print (int) 'gnu_obj_1::method()::sintvar'" "\\$\[0-9\]+ = 4" \ That's printing the "sintvar" function local static of the "gnu_obj_1::method()" method. The problem with that test is that that "'S::method()::static_var'" syntax doesn't really work in C++ as you'd expect. The way to make it work correctly currently is to quote the method part, not the whole expression, like: (gdb) print 'gnu_obj_1::method()'::sintvar If you wrap the whole expression in quotes, like in m-static.exp, what really happens is that the parser considers the whole string as a symbol name, but there's no debug symbol with that name. However, local statics have linkage and are given a mangled name that demangles to the same string as the full expression, so that's what GDB prints. After this commit, and without the cast, the print in m-static.exp would error out saying that the variable has unknown type: (gdb) p 'gnu_obj_1::method()::sintvar' 'gnu_obj_1::method()::sintvar' has unknown type; cast it to its declared type TBC, if currently (even before this series) you try to print any function local static variable of type other than int, you'll get bogus results. You can see that with m-static.cc as is, even. Printing the "svar" local, which is a boolean (1 byte) still prints as "int" (4 bytes): (gdb) p 'gnu_obj_1::method()::svar' $1 = 1 (gdb) ptype 'gnu_obj_1::method()::svar' type = <data variable, no debug info> This probably prints some random bogus value on big endian machines. If 'svar' was of some aggregate type (etc.) we'd still print it as int, so the problem would have been more obvious... After this commit, you'll get instead: (gdb) p 'gnu_obj_1::method()::svar' 'gnu_obj_1::method()::svar' has unknown type; cast it to its declared type ... so at least GDB is no longer misleading. Making GDB find the real local static debug symbol is the subject of the following patches.

Implement pahole-like 'ptype /o' option This commit implements the pahole-like '/o' option for 'ptype', which prints the offsets and sizes of struct fields, reporting whenever there is a hole found. The output is heavily based on pahole(1), with a few modifications here and there to adjust it to our reality. Here's an example: /* offset | size */ type = struct wer : public tuv { public: /* 32 | 24 */ struct tyu { /* 32:31 | 4 */ int a1 : 1; /* 32:28 | 4 */ int a2 : 3; /* 32: 5 | 4 */ int a3 : 23; /* 35: 3 | 1 */ char a4 : 2; /* XXX 3-bit hole */ /* XXX 4-byte hole */ /* 40 | 8 */ int64_t a5; /* 48:27 | 4 */ int a6 : 5; /* 48:56 | 8 */ int64_t a7 : 3; /* total size (bytes): 24 */ } a1; /* total size (bytes): 56 */ } A big part of this patch handles the formatting logic of 'ptype', which is a bit messy. The code to handle bitfield offsets, however, took some time to craft. My thanks to Pedro Alves for figuring things out and pointing me to the right direction, as well as coming up with a way to inspect the layout of structs with bitfields (see testcase for comments). After many discussions both on IRC and at the mailing list, I tried to implement printing vtables and inherited classes. Unfortunately the code grew too complex and there were still a few corner cases failing so I had to drop the attempt. This should be implemented in a future patch. This patch is the start of a long-term work I'll do to flush the local patches we carry for Fedora GDB.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression> This patch makes parse_expression and friends return a unique_ptr instead of raw pointer [1]: typedef gdb::unique_malloc_ptr<expression> expression_up; and then adjusts the codebase throughout to stop using cleanups to manage lifetime of expression pointers. Whenever I found a structure owning an expression pointer, I made it store a unique_ptr instead of a raw pointer, which then requires using new/delete of the holding structure, instead of XNEW/xfree. [1] - I'd like to set the rule that types named with an "_up" suffix are unique_ptr typedefs. Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply because we still use xmalloc instead of new to allocate expression objects. Once that's changed, all we need to do is change the expression_up typedef and the smart pointer will then call delete instead of xfree. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_read_renaming_var_value): Use expression_up.

Fix type casts losing typedefs and reimplement "whatis" typedef stripping (Ref: https://sourceware.org/ml/gdb/2017-06/msg00020.html) Assuming int_t is a typedef to int: typedef int int_t; gdb currently loses this expression's typedef: (gdb) p (int_t) 0 $1 = 0 (gdb) whatis $1 type = int or: (gdb) whatis (int_t) 0 type = int or, to get "whatis" out of the way: (gdb) maint print type (int_t) 0 ... name 'int' code 0x8 (TYPE_CODE_INT) ... This prevents a type printer for "int_t" kicking in, with e.g.: (gdb) p (int_t) 0 From the manual, we can see that that "whatis (int_t) 0" command invocation should have printed "type = int_t": If @var{arg} is a variable or an expression, @code{whatis} prints its literal type as it is used in the source code. If the type was defined using a @code{typedef}, @code{whatis} will @emph{not} print the data type underlying the @code{typedef}. (...) If @var{arg} is a type name that was defined using @code{typedef}, @code{whatis} @dfn{unrolls} only one level of that @code{typedef}. That one-level stripping is currently done here, in gdb/eval.c:evaluate_subexp_standard, handling OP_TYPE: ... else if (noside == EVAL_AVOID_SIDE_EFFECTS) { struct type *type = exp->elts[pc + 1].type; /* If this is a typedef, then find its immediate target. We use check_typedef to resolve stubs, but we ignore its result because we do not want to dig past all typedefs. */ check_typedef (type); if (TYPE_CODE (type) == TYPE_CODE_TYPEDEF) type = TYPE_TARGET_TYPE (type); return allocate_value (type); } However, this stripping is reachable in both: #1 - (gdb) whatis (int_t)0 # ARG is an expression with a cast to # typedef type. #2 - (gdb) whatis int_t # ARG is a type name. while only case #2 should strip the typedef. Removing that code from evaluate_subexp_standard is part of the fix. Instead, we make the "whatis" command implementation itself strip one level of typedefs when the command argument is a type name. We then run into another problem, also fixed by this commit: value_cast always drops any typedefs of the destination type. With all that fixed, "whatis (int_t) 0" now works as expected: (gdb) whatis int_t type = int (gdb) whatis (int_t)0 type = int_t value_cast has many different exit/convertion paths, for handling many different kinds of casts/conversions, and most of them had to be tweaked to construct the value of the right "to" type. The new tests try to exercise most of it, by trying castin of many different combinations of types. With: $ make check TESTS="*/whatis-ptype*.exp */gnu_vector.exp */dfp-test.exp" ... due to combinatorial explosion, the testsuite results for the tests above alone grow like: - # of expected passes 246 + # of expected passes 3811 You'll note that the tests exposed one GCC buglet, filed here: Missing DW_AT_type in DW_TAG_typedef of "typedef of typedef of void" https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81267 gdb/ChangeLog: 2017-08-21 Pedro Alves <palves@redhat.com> * eval.c (evaluate_subexp_standard) <OP_TYPE>: Don't dig past typedefs. * typeprint.c (whatis_exp): If handling "whatis", and expression is OP_TYPE, strip one typedef level.

Fix type casts losing typedefs and reimplement "whatis" typedef stripping (Ref: https://sourceware.org/ml/gdb/2017-06/msg00020.html) Assuming int_t is a typedef to int: typedef int int_t; gdb currently loses this expression's typedef: (gdb) p (int_t) 0 $1 = 0 (gdb) whatis $1 type = int or: (gdb) whatis (int_t) 0 type = int or, to get "whatis" out of the way: (gdb) maint print type (int_t) 0 ... name 'int' code 0x8 (TYPE_CODE_INT) ... This prevents a type printer for "int_t" kicking in, with e.g.: (gdb) p (int_t) 0 From the manual, we can see that that "whatis (int_t) 0" command invocation should have printed "type = int_t": If @var{arg} is a variable or an expression, @code{whatis} prints its literal type as it is used in the source code. If the type was defined using a @code{typedef}, @code{whatis} will @emph{not} print the data type underlying the @code{typedef}. (...) If @var{arg} is a type name that was defined using @code{typedef}, @code{whatis} @dfn{unrolls} only one level of that @code{typedef}. That one-level stripping is currently done here, in gdb/eval.c:evaluate_subexp_standard, handling OP_TYPE: ... else if (noside == EVAL_AVOID_SIDE_EFFECTS) { struct type *type = exp->elts[pc + 1].type; /* If this is a typedef, then find its immediate target.

Removing that code from evaluate_subexp_standard is part of the fix. Instead, we make the "whatis" command implementation itself strip one level of typedefs when the command argument is a type name. We then run into another problem, also fixed by this commit: value_cast always drops any typedefs of the destination type. With all that fixed, "whatis (int_t) 0" now works as expected: (gdb) whatis int_t type = int (gdb) whatis (int_t)0 type = int_t value_cast has many different exit/convertion paths, for handling many different kinds of casts/conversions, and most of them had to be tweaked to construct the value of the right "to" type.

Convert lvalue reference type check to general reference type check In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent. That means that in all but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE check and, for switch statements, add a case label for a rvalue reference type next to a case label for an lvalue reference type. This patch does exactly that. gdb/ChangeLog PR gdb/14441 * aarch64-tdep.c (aarch64_type_align) (aarch64_extract_return_value, aarch64_store_return_value): Change lvalue reference type checks to general reference type checks. * amd64-tdep.c (amd64_classify): Likewise. * amd64-windows-tdep.c (amd64_windows_passed_by_integer_register): Likewise. * arm-tdep.c (arm_type_align, arm_extract_return_value) (arm_store_return_value): Likewise. * ax-gdb.c (gen_fetch, gen_cast): Likewise. * c-typeprint.c (c_print_type): Likewise. * c-varobj.c (adjust_value_for_child_access, c_value_of_variable) (cplus_number_of_children, cplus_describe_child): Likewise. * compile/compile-c-symbols.c (generate_vla_size): Likewise. * completer.c (expression_completer): Likewise. * cp-support.c (make_symbol_overload_list_adl_namespace): Likewise. * darwin-nat-info.c (info_mach_region_command): Likewise. * dwarf2loc.c (entry_data_value_coerce_ref) (value_of_dwarf_reg_entry): Likewise. * eval.c (ptrmath_type_p, evaluate_subexp_standard) (evaluate_subexp_for_address, evaluate_subexp_for_sizeof): Likewise. * findvar.c (extract_typed_address, store_typed_address): Likewise. * gdbtypes.c (rank_one_type): Likewise. * hppa-tdep.c (hppa64_integral_or_pointer_p): Likewise. * infcall.c (value_arg_coerce): Likewise. * language.c (pointer_type): Likewise. * m32c-tdep.c (m32c_reg_arg_type, m32c_m16c_address_to_pointer): Likewise. * m88k-tdep.c (m88k_integral_or_pointer_p): Likewise. * mn10300-tdep.c (mn10300_type_align): Likewise. * msp430-tdep.c (msp430_push_dummy_call): Likewise. * ppc-sysv-tdep.c (do_ppc_sysv_return_value) (ppc64_sysv_abi_push_param, ppc64_sysv_abi_return_value): Likewise. * printcmd.c (print_formatted, x_command): Likewise. * python/py-type.c (typy_get_composite, typy_template_argument): Likewise. * python/py-value.c (valpy_referenced_value) (valpy_get_dynamic_type, value_has_field): Likewise. * s390-linux-tdep.c (s390_function_arg_integer): Likewise. * sparc-tdep.c (sparc_integral_or_pointer_p): Likewise. * sparc64-tdep.c (sparc64_integral_or_pointer_p): Likewise. * spu-tdep.c (spu_scalar_value_p): Likewise. * symtab.c (lookup_symbol_aux): Likewise. * typeprint.c (whatis_exp, print_type_scalar): Likewise. * valarith.c (binop_types_user_defined_p, unop_user_defined_p): Likewise. * valops.c (value_cast_pointers, value_cast) (value_reinterpret_cast, value_dynamic_cast, value_addr, typecmp) (value_struct_elt, value_struct_elt_bitpos) (value_find_oload_method_list, find_overload_match) (value_rtti_indirect_type): Likewise. * valprint.c (val_print_scalar_type_p, generic_val_print): Likewise. * value.c (value_actual_type, value_as_address, unpack_long) (pack_long, pack_unsigned_long, coerce_ref_if_computed) (coerce_ref): Likewise. * varobj.c (varobj_get_value_type): Likewise.

Implement pahole-like 'ptype /o' option This commit implements the pahole-like '/o' option for 'ptype', which prints the offsets and sizes of struct fields, reporting whenever there is a hole found. The output is heavily based on pahole(1), with a few modifications here and there to adjust it to our reality. Here's an example: /* offset | size */ type = struct wer : public tuv { public: /* 32 | 24 */ struct tyu { /* 32:31 | 4 */ int a1 : 1; /* 32:28 | 4 */ int a2 : 3; /* 32: 5 | 4 */ int a3 : 23; /* 35: 3 | 1 */ char a4 : 2; /* XXX 3-bit hole */ /* XXX 4-byte hole */ /* 40 | 8 */ int64_t a5; /* 48:27 | 4 */ int a6 : 5; /* 48:56 | 8 */ int64_t a7 : 3; /* total size (bytes): 24 */ } a1; /* total size (bytes): 56 */ } A big part of this patch handles the formatting logic of 'ptype', which is a bit messy. The code to handle bitfield offsets, however, took some time to craft. My thanks to Pedro Alves for figuring things out and pointing me to the right direction, as well as coming up with a way to inspect the layout of structs with bitfields (see testcase for comments). After many discussions both on IRC and at the mailing list, I tried to implement printing vtables and inherited classes. Unfortunately the code grew too complex and there were still a few corner cases failing so I had to drop the attempt. This should be implemented in a future patch. This patch is the start of a long-term work I'll do to flush the local patches we carry for Fedora GDB. In this specific case, I'm aiming at upstreaming the feature implemented by the 'pahole.py' script that is shipped with Fedora GDB: <https://src.fedoraproject.org/rpms/gdb/blob/master/f/gdb-archer.patch#_311> This has been regression-tested on the BuildBot. There's a new testcase for it, along with an update to the documentation. I also thought it was worth mentioning this feature in the NEWS file. gdb/ChangeLog: 2017-12-15 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> PR cli/16224 * NEWS (Changes since GDB 8.0): Mention new '/o' flag. * c-typeprint.c (OFFSET_SPC_LEN): New define.

/* Print integral scalar data VAL, of type TYPE, onto stdio stream STREAM.
Used to print data from type structures in a specified type. For example,
array bounds may be characters or booleans in some languages, and this
allows the ranges to be printed in their "natural" form rather than as
decimal integer values.
FIXME: This is here simply because only the type printing routines
currently use it, and it wasn't clear if it really belonged somewhere
else (like printcmd.c). There are a lot of other gdb routines that do
something similar, but they are generally concerned with printing values

that come from the inferior in target byte order and target size. */

Remove CHECK_TYPEDEF, use check_typedef instead I think that the CHECK_TYPEDEF macro is not necessary, and even a bit annoying. It makes unclear the fact that the "type" variables gets overwritten. It has actually bitten me a few times. I think the following, explicit form, is better. type = check_typedef (type); This patches changes all instances of CHECK_TYPEDEF for an equivalent call to check_typedef. The bulk of the change was done with this sed: sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c The ChangeLog was generated using David Malcom's generate_changelog.py. I manually fixed those places where it gets the wrong function name, hopefully all of them.

Convert lvalue reference type check to general reference type check In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent.

Constify add_prefix_cmd This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

Record nested types GDB currently does not track types defined in classes. Consider: class A { public: class B { public: class C { }; }; }; (gdb) ptype A type = class A { <no data fields> } This patch changes this behavior so that GDB records these nested types and displays them to the user when he has set the (new) "print type" option "nested-type-limit." Example: (gdb) set print type nested-type-limit 1 (gdb) ptype A type = class A { <no data fields> class A::B { <no data fields> }; } (gdb) set print type nested-type-limit 2 type = class A { <no data fields> class A::B { <no data fields> class A::B::C { <no data fields> }; }; } By default, the code maintains the status quo, that is, it will not print any nested type definitions at all. Testing is carried out via cp_ptype_class which required quite a bit of modification to permit recursive calling (for the nested types). This was most easily facilitated by turning the ptype command output into a queue. Upshot: the test suite now has stack and queue data structures that may be used by test writers. gdb/ChangeLog * NEWS (New commands): Mention set/show print type nested-type-limit. * c-typeprint.c (c_type_print_base): Print out nested types. * dwarf2read.c (struct typedef_field_list): Rename to ...

Implement pahole-like 'ptype /o' option This commit implements the pahole-like '/o' option for 'ptype', which prints the offsets and sizes of struct fields, reporting whenever there is a hole found. The output is heavily based on pahole(1), with a few modifications here and there to adjust it to our reality. Here's an example: /* offset | size */ type = struct wer : public tuv { public: /* 32 | 24 */ struct tyu { /* 32:31 | 4 */ int a1 : 1; /* 32:28 | 4 */ int a2 : 3; /* 32: 5 | 4 */ int a3 : 23; /* 35: 3 | 1 */ char a4 : 2; /* XXX 3-bit hole */ /* XXX 4-byte hole */ /* 40 | 8 */ int64_t a5; /* 48:27 | 4 */ int a6 : 5; /* 48:56 | 8 */ int64_t a7 : 3; /* total size (bytes): 24 */ } a1; /* total size (bytes): 56 */ } A big part of this patch handles the formatting logic of 'ptype', which is a bit messy. The code to handle bitfield offsets, however, took some time to craft. My thanks to Pedro Alves for figuring things out and pointing me to the right direction, as well as coming up with a way to inspect the layout of structs with bitfields (see testcase for comments). After many discussions both on IRC and at the mailing list, I tried to implement printing vtables and inherited classes. Unfortunately the code grew too complex and there were still a few corner cases failing so I had to drop the attempt. This should be implemented in a future patch. This patch is the start of a long-term work I'll do to flush the local patches we carry for Fedora GDB. In this specific case, I'm aiming at upstreaming the feature implemented by the 'pahole.py' script that is shipped with Fedora GDB: <https://src.fedoraproject.org/rpms/gdb/blob/master/f/gdb-archer.patch#_311> This has been regression-tested on the BuildBot. There's a new testcase for it, along with an update to the documentation.

fort_dyn_array: add basic fortran dyn array support Fortran provide types whose values may be dynamically allocated or associated with a variable under explicit program control. The purpose of this commit is: * to read allocated/associated DWARF tags and store them in the dynamic property list of main_type. * enable GDB to print the value of a dynamic array in Fortran in case the type is allocated or associated (pointer to dynamic array). Examples: (gdb) p vla_not_allocated $1 = <not allocated> (gdb) p vla_allocated $1 = (1, 2, 3) (gdb) p vla_ptr_not_associated $1 = <not associated> (gdb) p vla_ptr_associated $1 = (1, 2, 3) Add basic test coverage for most dynamic array use-cases in Fortran. The commit contains the following tests: * Ensure that values of Fortran dynamic arrays can be evaluated correctly in various ways and states. * Ensure that Fortran primitives can be evaluated correctly when used as a dynamic array. * Dynamic arrays passed to subroutines and handled in different ways inside the routine. * Ensure that the ptype of dynamic arrays in Fortran can be printed in GDB correctly. * Ensure that dynamic arrays in different states (allocated/associated) can be evaluated. * Dynamic arrays passed to functions and returned from functions. * History values of dynamic arrays can be accessed and printed again with the correct values. * Dynamic array evaluations using MI protocol. * Sizeof output of dynamic arrays in various states. The patch was tested using the test suite on Ubuntu 12.04 64bit. gdb/ChangeLog: * dwarf2read.c (set_die_type): Add read of DW_AT_allocated and DW_AT_associated. * f-typeprint.c: New include of typeprint.h (f_print_type): Add check for allocated/associated status of type.
