2016-11-08Remove parameter valaddr from la_val_printYao Qi1-7/+6
Nowadays, we pass both val and return value of value_contents_for_printing (val) to la_val_print. The latter is unnecessary. This patch removes the second parameter of la_val_print, and get valaddr in each language's implementation by calling value_contents_for_printing. Since value_contents_for_printing calls value_fetch_lazy, I also make VAL non-const. Note that - I don't clean up the valaddr usages in each language's routines, - I don't remove valaddr from apply_ext_lang_val_pretty_printer, and extension language ops apply_val_pretty_printer. They can be done in followup patches. gdb: 2016-11-08 Yao Qi <yao.qi@linaro.org> * ada-lang.h (ada_val_print): Remove second parameter.

2016-06-24Support structure offsets that are 512K or larger.David Taylor1-7/+8
GDB computes structure byte offsets using a 32 bit integer. And, first it computes the offset in bits and then converts to bytes. The result is that any offset that if 512K bytes or larger overflows. This patch changes GDB to use LONGEST for such calculations.

2015-09-25Add casts to memory allocation related callsSimon Marchi1-1/+1
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.

2015-07-14Remove CHECK_TYPEDEF, use check_typedef insteadSimon Marchi1-2/+2
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.

2015-03-07Split TRY_CATCH into TRY + CATCHPedro Alves1-9/+12
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.

2015-03-07Normalize TRY_CATCH exception handling blockPedro Alves1-8/+10
This normalizes some exception catch blocks that check for ex.reason to look like this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ALL) { ... } if (ex.reason < 0) { ... } ~~~ This is a preparation step for running a script that converts all TRY_CATCH uses to look like this instead: ~~~ TRY { ... } CATCH (ex, RETURN_MASK_ALL) { ... } END_CATCH ~~~ The motivation for that change is being able to reimplent TRY/CATCH in terms of C++ try/catch. This commit makes it so that: - no condition other than ex.reason < 0 is checked in the if predicate - there's no "else" block to check whether no exception was caught - there's no code between the TRY_CATCH (TRY) block and the 'if (ex.reason < 0)' block (CATCH). - the exception object is no longer referred to outside the if/catch block. Note the local volatile exception objects that are currently defined inside functions that use TRY_CATCH will disappear. In cases it's more convenient to still refer to the exception outside the catch block, a new non-volatile local is added and copy to that object is made within the catch block. The following patches should make this all clearer. gdb/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> * amd64-tdep.c (amd64_frame_cache, amd64_sigtramp_frame_cache) (amd64_epilogue_frame_cache): Normal exception handling code. * break-catch-throw.c (check_status_exception_catchpoint) (re_set_exception_catchpoint): Ditto. * cli/cli-interp.c (safe_execute_command): * cli/cli-script.c (script_from_file): Ditto. * compile/compile-c-symbols.c (generate_c_for_for_one_variable): Ditto. * compile/compile-object-run.c (compile_object_run): Ditto. * cp-abi.c (baseclass_offset): Ditto. * cp-valprint.c (cp_print_value): Ditto. * exceptions.c (catch_exceptions_with_msg): * frame-unwind.c (frame_unwind_try_unwinder): Ditto. * frame.c (get_frame_address_in_block_if_available): Ditto. * i386-tdep.c (i386_frame_cache, i386_epilogue_frame_cache) (i386_sigtramp_frame_cache): Ditto. * infcmd.c (post_create_inferior): Ditto. * linespec.c (parse_linespec, find_linespec_symbols): * p-valprint.c (pascal_object_print_value): Ditto. * parse.c (parse_expression_for_completion): Ditto. * python/py-finishbreakpoint.c (bpfinishpy_init): Ditto. * remote.c (remote_get_noisy_reply): Ditto. * s390-linux-tdep.c (s390_frame_unwind_cache): Ditto. * solib-svr4.c (solib_svr4_r_map): Ditto.
2015-02-27Exported const objectsPedro Alves1-1/+1
const works different in C vs C++. In C++, a global "const" variable has internal linkage by default, resulting in link errors like: ... extension.o: In function `get_ext_lang_defn(extension_language)': gdb/extension.c:126: undefined reference to `extension_language_guile' gdb/extension.c:124: undefined reference to `extension_language_guile' ... The fix is to define exported const objects with "extern const". But that in C would not be a definition. So we need to #ifdef C vs C++ in this case. EXPORTED_CONST comes from include/ansidecl.h, but in the feature_to_c.sh case I think it's better to leave the script with no dependencies. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * cp-valprint.c (vtbl_ptr_name): Use EXPORTED_CONST. * guile/guile.c (extension_language_guile): Use EXPORTED_CONST. * features/feature_to_c.sh: Tag the generated xml_builtin array with extern const in C++ mode.
2015-02-27C++ keyword cleanliness, mostly auto-generatedPedro Alves1-2/+2
This patch renames symbols that happen to have names which are reserved keywords in C++. Most of this was generated with Tromey's cxx-conversion.el script. Some places where later hand massaged a bit, to fix formatting, etc. And this was rebased several times meanwhile, along with re-running the script, so re-running the script from scratch probably does not result in the exact same output. I don't think that matters anyway. gdb/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout. gdb/gdbserver/ 2015-02-27 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> Rename symbols whose names are reserved C++ keywords throughout.
2015-01-31Move TYPE_SELF_TYPE into new field type_specific.Doug Evans1-24/+23
This patch moves TYPE_SELF_TYPE into new field type_specific.self_type for MEMBERPTR,METHODPTR types, and into type_specific.func_stuff for METHODs, and then updates everything to use that. TYPE_CODE_METHOD could share some things with TYPE_CODE_FUNC (e.g. TYPE_NO_RETURN) and it seemed simplest to keep them together. Moving TYPE_SELF_TYPE into type_specific.func_stuff for TYPE_CODE_METHOD is also nice because when we allocate space for function types we assume they're TYPE_CODE_FUNCs. If TYPE_CODE_METHODs don't need or use that space then that space would be wasted, and cleaning that up would involve more invasive changes. In order to catch errant uses I've added accessor functions that do some checking. One can no longer assign to TYPE_SELF_TYPE like this: TYPE_SELF_TYPE (foo) = bar; One instead has to do: set_type_self_type (foo, bar); But I've left reading of the type to the macro: bar = TYPE_SELF_TYPE (foo); In order to discourage bypassing the TYPE_SELF_TYPE macro I've named the underlying function that implements it internal_type_self_type. While testing this I found the stabs reader leaving methods as TYPE_CODE_FUNCs, hitting my newly added asserts. Since the dwarf reader smashes functions to methods (via smash_to_method) I've done a similar thing for stabs. gdb/ChangeLog: * cp-valprint.c (cp_find_class_member): Rename parameter domain_p to self_p.

The PRs are about variables described by the DWARF as being split over multiple registers using DWARF piece information, but some of those registers being marked as optimised out (not saved) by a later frame. GDB currently incorrectly mishandles these partially-optimized-out values. Even though we can usually tell from the debug info whether a local or global is optimized out, handling the case of a local living in a register that was not saved in a frame requires fetching the variable. GDB also needs to fetch a value to tell whether parts of it are "<unavailable>". Given this, it's not worth it to try to avoid fetching lazy optimized-out values based on debug info alone. So this patch makes GDB track which chunks of a value's contents are optimized out like it tracks <unavailable> contents. That is, it makes value->optimized_out be a bit range vector instead of a boolean, and removes the struct lval_funcs check_validity and check_any_valid hooks. Unlike Andrew's series which this is based on (at https://sourceware.org/ml/gdb-patches/2013-08/msg00300.html, note some pieces have gone in since), this doesn't merge optimized out and unavailable contents validity/availability behind a single interface, nor does it merge the bit range vectors themselves (at least yet). While it may be desirable to have a single entry point that returns existence of contents irrespective of what may make them invalid/unavailable, several places want to treat optimized out / unavailable / etc. differently, so each spot that potentially could use it will need to be careful considered on case-by-case basis, and best done as a separate change. This fixes Jan's test, because value_available_contents_eq wasn't considering optimized out value contents. It does now, and because of that it's been renamed to value_contents_eq. A new intro comment is added to value.h describing "<optimized out>", "<not saved>" and "<unavailable>" values. gdb/ PR symtab/14604 PR symtab/14605 * ada-lang.c (coerce_unspec_val_to_type): Use value_contents_copy_raw. * ada-valprint.c (val_print_packed_array_elements): Adjust. * c-valprint.c (c_val_print): Use value_bits_any_optimized_out. * cp-valprint.c (cp_print_value_fields): Let the common printing code handle optimized out values.

2013-10-25Print nonexisting/optimized out static fields gracefully.Pedro Alves1-7/+10
With: struct static_struct { static int aaa; }; struct static_struct sss; int main () { return 0; } We get: (gdb) p sss $1 = {static aaa = <optimized out>} (gdb) p sss.aaa field aaa is nonexistent or has been optimized out Note that the "field aaa ..." message is an error being thrown. GDB is graceful everywhere else when printing optimized out values. IOW it usually prints an <optimized out> value and puts that in the value history. I see no reason for here to be different, more so that when the print the whole "containing" object (well, it's a static field, so it's not really a container), we already print <optimized out>. After the patch: (gdb) p sss $1 = {static aaa = <optimized out>} (gdb) p sss.aaa $2 = <optimized out> The value_entirely_optimized_out checks are there to preserve behavior. Without those, if the static field is a struct/union, GDB would go and print its fields one by one (and print <optimized out> for each).

2013-10-02Print registers not saved in the frame as "<not saved>" instead of ↵Pedro Alves1-2/+2
"<optimized out>". Currently, in some scenarios, GDB prints <optimized out> when printing outer frame registers. An <optimized out> register is a confusing concept. What this really means is that the register is call-clobbered, or IOW, not saved by the callee. This patch makes GDB say that instead. Before patch: (gdb) p/x $rax $1 = <optimized out> (gdb) info registers rax rax <optimized out> After patch: (gdb) p/x $rax $1 = <not saved> (gdb) info registers rax rax <not saved> However, if for some reason the debug info describes a variable as being in such a register (**), we still want to print <optimized out> when printing the variable. IOW, <not saved> is reserved for inspecting registers at the machine level. The patch uses lval_register+optimized_out to encode the not saved registers, and makes it so that optimized out variables always end up in !lval_register values. ** See <https://sourceware.org/ml/gdb-patches/2012-08/msg00787.html>. Current/recent enough GCC doesn't mark variables/arguments as being in call-clobbered registers in the ranges corresponding to function calls, while older GCCs did. Newer GCCs will just not say where the variable is, so GDB will end up realizing the variable is optimized out. frame_unwind_got_optimized creates not_lval optimized out registers, so by default, in most cases, we'll see <optimized out>. value_of_register is the function eval.c uses for evaluating OP_REGISTER (again, $pc, etc.), and related bits. It isn't used for anything else. This function makes sure to return lval_register values. The patch makes "info registers" and the MI equivalent use it too. I think it just makes a lot of sense, as this makes it so that when printing machine registers ($pc, etc.), we go through a central function. We're likely to need a different encoding at some point, if/when we support partially saved registers. Even then, I think value_of_register will still be the spot to tag the intention to print machine register values differently. value_from_register however may also return optimized out lval_register values, so at a couple places where we're computing a variable's location from a dwarf expression, we convert the resulting value away from lval_register to a regular optimized out value.
