(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.

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.

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.

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.

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.

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.

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.

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.

/* If TYPE is a derived type, then print out derivation information.
Print only the actual base classes of this type, not the base
classes of the base classes. I.e. for the derivation hierarchy:
1999-07-07 22:19:36 +02:00
class A { int a; };
class B : public A {int b; };
class C : public B {int c; };
Print the type of class C as:
1999-07-07 22:19:36 +02:00
class C : public B {
int c;
}
Not as the following (like gdb used to), which is not legal C++
syntax for derived types and may be confused with the multiple
inheritance form:
1999-07-07 22:19:36 +02:00
class C : public B : public A {
int c;
}
In general, gdb should try to print the types as closely as
possible to the form that they appear in the source code. */

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.

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.

If we found a file symtab, re-evaluate whether the remainder is_quoted. (decode_compound): Stop consuming at an open parenthesis. Keep template parameters. Keep any overload information. Keep keywords like "const". Remove paren_pointer. Move is_quoted check from set_flags to here. Remove #if 0 code from 2000. Ten years is long enough.

Remove Java support This patch removes the Java support from gdb. gcj has not seen much development or use for years now, and was recently removed from GCC. This patch changes gdb to follow; in the unlikely event that there are still users using gcj, they can continue to use an older gdb to debug. Or, they can debug in C++ mode. Built and regtested on x86-64 Fedora 24. 2016-10-06 Tom Tromey <tom@tromey.com> * MAINTAINERS: Remove Java test maintainer. * varobj.h (java_varobj_ops): Don't declare. * valprint.h (struct value_print_options) <pascal_static_field_print>: Update comment. * utils.c (producer_is_gcc): Remove java reference. * symtab.h (struct general_symbol_info): Remove java references.

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.

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.

Remove TYPE_TAG_NAME TYPE_TAG_NAME has been an occasional source of confusion and bugs. It seems to me that it is only useful for C and C++ -- but even there, not so much, because at least with DWARF there doesn't seem to be any way to wind up with a type where the name and the tag name are both non-NULL and different. So, this patch removes TYPE_TAG_NAME entirely. This should save a little memory, but more importantly, it simplifies this part of gdb. A few minor test suite adjustments were needed.

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.

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.

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.

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.

Remove TYPE_TAG_NAME TYPE_TAG_NAME has been an occasional source of confusion and bugs. It seems to me that it is only useful for C and C++ -- but even there, not so much, because at least with DWARF there doesn't seem to be any way to wind up with a type where the name and the tag name are both non-NULL and different. So, this patch removes TYPE_TAG_NAME entirely. This should save a little memory, but more importantly, it simplifies this part of gdb. A few minor test suite adjustments were needed.

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. The patch was built-tested, and I ran a few smoke tests. gdb/ChangeLog: * gdbtypes.h (CHECK_TYPEDEF): Remove. * aarch64-tdep.c (aarch64_return_in_memory): Replace CHECK_TYPEDEF with check_typedef. * ada-lang.c (decode_constrained_packed_array_type): Likewise.

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.

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.

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.

In some situations the new code does not yield identical output to the old code. gdb/ChangeLog 2018-06-01 Tom Tromey <tom@tromey.com> * valops.c (enum_constant_from_type, value_namespace_elt) (value_maybe_namespace_elt): Update. * valarith.c (find_size_for_pointer_math): Update. * target-descriptions.c (make_gdb_type): Update. * symmisc.c (print_symbol): Update. * stabsread.c (define_symbol, read_type) (complain_about_struct_wipeout, add_undefined_type) (cleanup_undefined_types_1): Update. * rust-lang.c (rust_tuple_type_p, rust_slice_type_p) (rust_range_type_p, val_print_struct, rust_print_struct_def) (rust_internal_print_type, rust_composite_type) (rust_evaluate_funcall, rust_evaluate_subexp) (rust_inclusive_range_type_p): Update. * python/py-type.c (typy_get_tag): Update. * p-typeprint.c (pascal_type_print_base): Update. * mdebugread.c (parse_symbol, parse_type): Update. * m2-typeprint.c (m2_long_set, m2_record_fields, m2_enum): Update. * guile/scm-type.c (gdbscm_type_tag): Update. * go-lang.c (sixg_string_p): Update. * gnu-v3-abi.c (build_gdb_vtable_type, build_std_type_info_type): Update. * gdbtypes.h (struct main_type) <tag_name>: Remove.

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.

Remove TYPE_TAG_NAME TYPE_TAG_NAME has been an occasional source of confusion and bugs. It seems to me that it is only useful for C and C++ -- but even there, not so much, because at least with DWARF there doesn't seem to be any way to wind up with a type where the name and the tag name are both non-NULL and different. So, this patch removes TYPE_TAG_NAME entirely. This should save a little memory, but more importantly, it simplifies this part of gdb. A few minor test suite adjustments were needed.

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.
