2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-09-18Move val_prettyformat to valprint.hTom Tromey1-0/+11
I stumbled across an ancient FIXME comment that was easy to fix -- val_prettyformat does not need to be in defs.h, and is easily moved to valprint.h, where (despite what the comment says) it belongs. Tested by rebuilding.
2023-01-19GDB: Add a character string limiting optionAndrew Burgess1-4/+22
This commit splits the `set/show print elements' option into two. We retain `set/show print elements' for controlling how many elements of an array we print, but a new `set/show print characters' setting is added which is used for controlling how many characters of a string are printed. The motivation behind this change is to allow users a finer level of control over how data is printed, reflecting that, although strings can be thought of as arrays of characters, users often want to treat these two things differently. For compatibility reasons by default the `set/show print characters' option is set to `elements', which makes the limit for character strings follow the setting of the `set/show print elements' option, as it used to. Using `set print characters' with any other value makes the limit independent from the `set/show print elements' setting, however it can be restored to the default with the `set print characters elements' command at any time. A corresponding `-characters' option for the `print' command is added, with the same semantics, i.e. one can use `elements' to make a given `print' invocation follow the limit of elements, be it set with the `-elements' option also given with the same invocation or taken from the `set/show print elements' setting, for characters as well regardless of the current setting of the `set/show print characters' option. The GDB changes are all pretty straightforward, just changing references to the old 'print_max' to use a new `get_print_max_chars' helper which figures out which of the two of `print_max' and `print_max_chars' values to use. Likewise, the documentation is just updated to reference the new setting where appropriate. To make people's life easier the message shown by `show print elements' now indicates if the setting also applies to character strings: (gdb) set print characters elements (gdb) show print elements Limit on string chars or array elements to print is 200. (gdb) set print characters unlimited (gdb) show print elements Limit on array elements to print is 200. (gdb) and the help text shows the dependency as well: (gdb) help set print elements Set limit on array elements to print. "unlimited" causes there to be no limit. This setting also applies to string chars when "print characters" is set to "elements". (gdb) In the testsuite there are two minor updates, one to add `-characters' to the list of completions now shown for the `print' command, and a bare minimum pair of checks for the right handling of `set print characters' and `show print characters', copied from the corresponding checks for `set print elements' and `show print elements' respectively.

2022-09-21gdb: remove TYPE_LENGTHSimon Marchi1-1/+1
Remove the macro, replace all uses with calls to type::length. Change-Id: Ib9bdc954576860b21190886534c99103d6a47afb
2022-06-20Move finish_print out of value_print_optionsTom Tromey1-3/+0
'finish_print' does not really belong in value_print_options -- this is consulted only when deciding whether or not to print a value, and never during the course of printing. This patch removes it from the structure and makes it a static global in infcmd.c instead. Tested on x86-64 Fedora 34.
2022-06-18gdb: Add new 'print nibbles' featureEnze Li1-1/+5
Make an introduction of a new print setting that can be set by 'set print nibbles [on|off]'. The default value if OFF, which can be changed by user manually. Of course, 'show print nibbles' is also included in the patch. The new feature displays binary values by group, with four bits per group. The motivation for this work is to enhance the readability of binary values. Here's a GDB session before this patch is applied. (gdb) print var_a $1 = 1230 (gdb) print/t var_a $2 = 10011001110 With this patch applied, we can use the new print setting to display the new form of the binary values. (gdb) print var_a $1 = 1230 (gdb) print/t var_a $2 = 10011001110 (gdb) set print nibbles on (gdb) print/t var_a $3 = 0100 1100 1110 Tested on x86_64 openSUSE Tumbleweed.
2022-04-14Move target_read_string to target/target.cTom Tromey1-5/+0
This moves the two overloads of target_read_string to a new file, target/target.c, and updates both gdb and gdbserver to build this.
2022-04-14Remove the byte order parameter to target_read_stringTom Tromey1-1/+0
target_read_string takes a byte order parameter, but only uses this to check whether a given character is zero. This is readily done without requiring the parameter, so remove it.
2022-04-14Rename read_stringTom Tromey1-5/+5
This renames read_string to be an overload of target_read_string. This makes it more consistent for the eventual merger with gdbserver.
2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-03-24Extend "x" and "print" commands to support memory taggingLuis Machado1-0/+4
Extend the "x" and "print" commands to make use of memory tagging functionality, if supported by the architecture. The "print" command will point out any possible tag mismatches it finds when dealing with pointers, in case such a pointer is tagged. No additional modifiers are needed. Suppose we have a pointer "p" with value 0x1234 (logical tag 0x0) and that we have an allocation tag of 0x1 for that particular area of memory. This is the expected output: (gdb) p/x p Logical tag (0x0) does not match the allocation tag (0x1). $1 = 0x1234 The "x" command has a new 'm' modifier that will enable displaying of allocation tags alongside the data dump. It will display one allocation tag per line. AArch64 has a tag granule of 16 bytes, which means we can have one tag for every 16 bytes of memory. In this case, this is what the "x" command will display with the new 'm' modifier: (gdb) x/32bxm p <Allocation Tag 0x1 for range [0x1230,0x1240)> 0x1234: 0x01 0x02 0x00 0x00 0x00 0x00 0x00 0x00 0x123c: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 <Allocation Tag 0x1 for range [0x1240,0x1250)> 0x1244: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x124c: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 (gdb) x/4gxm a <Allocation Tag 0x1 for range [0x1230,0x1240)> 0x1234: 0x0000000000000201 0x0000000000000000 <Allocation Tag 0x1 for range [0x1240,0x1250)> 0x1244: 0x0000000000000000 0x0000000000000000 gdb/ChangeLog: 2021-03-24 Luis Machado <luis.machado@linaro.org> * printcmd.c (decode_format): Handle the 'm' modifier.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-1/+1
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

2020-03-13Introduce common_val_print_checkedTom Tromey1-0/+8
A (much) later patch will remove the call to value_check_printable from common_val_print. This will needed to preserve some details of how optimized-out structures are printed. However, doing this will also break dw2-op-out-param.exp. Making the change causes "bt" to print: However, the test wants to see: ... operand2=<optimized out> That is, a wholly-optimized out structure should not print its fields. So, this patch introduces a new common_val_print_checked, which calls value_check_printable first, and then arranges to use it in the one spot that affects the test suite. I was not completely sure if it would be preferable to change the test. However, I reasoned that, assuming this output was intentional in the first place, in a backtrace space is at a premium and so this is a reasonable approach. In other spots calling common_val_print, this behavior is probably unintended, or at least a "don't care". gdb/ChangeLog 2020-03-13 Tom Tromey <tom@tromey.com> * valprint.h (common_val_print_checked): Declare. * valprint.c (common_val_print_checked): New function. * stack.c (print_frame_arg): Use common_val_print_checked.

2019-07-27Restrict use of minsym names when printing addresses in disassembled codeKevin Buettner1-4/+9
build_address_symbolic contains some code which causes it to prefer the minsym over the the function symbol in certain cases. The cases where this occurs are the same as the "certain pathological cases" that used to exist in find_frame_funname(). This commit largely disables that code; it will only prefer the minsym when the address of minsym is identical to that of the address under consideration AND the function address for the symbtab sym is not the same as the address under consideration. So, without this change, when using the dw2-ranges-func-lo-cold executable from the gdb.dwarf2/dw2-ranges-func.exp test, GDB exhibits the following behavior: (gdb) x/5i foo_cold 0x40110d <foo+4294967277>: push %rbp 0x40110e <foo+4294967278>: mov %rsp,%rbp 0x401111 <foo+4294967281>: callq 0x401106 <baz> 0x401116 <foo+4294967286>: nop 0x401117 <foo+4294967287>: pop %rbp On the other hand, still without this change, using the dw2-ranges-func-hi-cold executable from the same test, GDB does this instead: (gdb) x/5i foo_cold 0x401128 <foo_cold>: push %rbp 0x401129 <foo_cold+1>: mov %rsp,%rbp 0x40112c <foo_cold+4>: callq 0x401134 <baz> 0x401131 <foo_cold+9>: nop 0x401132 <foo_cold+10>: pop %rbp This is inconsistent behavior. When foo_cold is at a lower address than the function's entry point, the symtab symbol (foo) is displayed along with a large positive offset which would wrap around the address space if the address space were only 32 bits wide. (A later patch fixes this problem by displaying negative offsets.) This commit makes the behavior uniform for both the "lo-cold" and "hi-cold" cases: lo-cold: (gdb) x/5i foo_cold 0x40110d <foo_cold>: push %rbp 0x40110e <foo-18>: mov %rsp,%rbp 0x401111 <foo-15>: callq 0x401106 <baz> 0x401116 <foo-10>: nop 0x401117 <foo-9>: pop %rbp hi-cold: (gdb) x/5i foo_cold 0x401128 <foo_cold>: push %rbp 0x401129 <foo+35>: mov %rsp,%rbp 0x40112c <foo+38>: callq 0x401134 <baz> 0x401131 <foo+43>: nop 0x401132 <foo+44>: pop %rbp In both cases, the symbol shown for the address at which foo_cold resides is shown as <foo_cold>. Subsequent offsets are shown as either negative or positive offsets from the entry pc for foo. When disassembling a function, care must be taken to NOT display <+0> as the offset for the second range. For this reason, I found it necessary to add the "prefer_sym_over_minsym" parameter to build_address_symbolic. The type of this flag is a bool; do_demangle ought to be a bool also, so I made this change at the same time. gdb/ChangeLog: * valprint.h (build_address_symbolic): Add "prefer_sym_over_minsym" parameter. Change type of "do_demangle" to bool. * disasm.c (gdb_pretty_print_disassembler::pretty_print_insn): Pass suitable "prefer_sym_over_minsym" flag to build_address_symbolic().

2019-06-13Make "print" and "compile print" support -OPT optionsPedro Alves1-2/+18
This patch adds support for "print -option optval --", etc. Likewise for "compile print". We'll get: ~~~~~~ (gdb) help print Print value of expression EXP. Usage: print [[OPTION]... --] [/FMT] [EXP] Options: -address [on|off] Set printing of addresses. -array [on|off] Set pretty formatting of arrays. -array-indexes [on|off] Set printing of array indexes. -elements NUMBER|unlimited Set limit on string chars or array elements to print. "unlimited" causes there to be no limit. -max-depth NUMBER|unlimited Set maximum print depth for nested structures, unions and arrays. When structures, unions, or arrays are nested beyond this depth then they will be replaced with either '{...}' or '(...)' depending on the language. Use "unlimited" to print the complete structure. -null-stop [on|off] Set printing of char arrays to stop at first null char. -object [on|off] Set printing of C++ virtual function tables. -pretty [on|off] Set pretty formatting of structures. -repeats NUMBER|unlimited Set threshold for repeated print elements. "unlimited" causes all elements to be individually printed. -static-members [on|off] Set printing of C++ static members. -symbol [on|off] Set printing of symbol names when printing pointers. -union [on|off] Set printing of unions interior to structures. -vtbl [on|off] Set printing of C++ virtual function tables. Note: because this command accepts arbitrary expressions, if you specify any command option, you must use a double dash ("--") to mark the end of option processing. E.g.: "print -o -- myobj". ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I want to highlight the comment above about "--". At first, I thought we could make the print command parse the options, and if the option wasn't recognized, fallback to parsing as an expression. Then, if the user wanted to disambiguate, he'd use the "--" option delimiter. For example, if you had a variable called "object" and you wanted to print its negative, you'd have to do: (gdb) print -- -object After getting that working, I saw that gdb.pascal/floats.exp regressed, in these tests: gdb_test "print -r" " = -1\\.2(499.*|5|500.*)" gdb_test "print -(r)" " = -1.2(499.*|5|500.*)" gdb_test "print -(r + s)" " = -3\\.4(499.*|5|500.*)" It's the first one that I found most concerning. It regressed because "-r" is the abbreviation of "-raw". I realized then that the behavior change was a bit risker than I'd like, considering scripts, wrappers around gdb, etc., and even user expectation. So instead, I made the print command _require_ the "--" options delimiter if you want to specify any option. So: (gdb) print -r is parsed as an expression, and (gdb) print -r -- is parsed as an option. I noticed that that's also what lldb's expr (the equivalent of print) does to handle the same problem. Going back the options themselves, note that: - you can shorten option names, as long as unambiguous. - For boolean options, 0/1 stand for off/on. - For boolean options, "true" is implied. So these are all equivalent: (gdb) print -object on -static-members off -pretty on -- foo (gdb) print -object -static-members off -pretty -- foo (gdb) print -object -static-members 0 -pretty -- foo (gdb) print -o -st 0 -p -- foo TAB completion is fully supported: (gdb) p -[TAB] -address -elements -pretty -symbol -array -null-stop -repeats -union -array-indexes -object -static-members -vtbl Note that the code is organized such that some of the options and the "set/show" commands code is shared. In particular, the "print" options and the corresponding "set print" commands are defined with the same structures.

2019-05-29Add "set print finish"Tom Tromey1-0/+3
A user wanted to be able to disable the display of the value when using "finish" -- but still have the value entered into the value history in case it was useful later on. Part of the rationale here is that sometimes the value might be quite large, or expensive to display (in their case this was compounded by a rogue pretty-printer).

2019-04-29gdb: Introduce 'print max-depth' featureAndrew Burgess1-0/+12
Introduce a new print setting max-depth which can be set with 'set print max-depth DEPTH'. The default value of DEPTH is 20, but this can also be set to unlimited. When GDB is printing a value containing nested structures GDB will stop descending at depth DEPTH. Here is a small example: typedef struct s1 { int a; } s1; typedef struct s2 { s1 b; } s2; typedef struct s3 { s2 c; } s3; typedef struct s4 { s3 d; } s4; s4 var = { { { { 3 } } } }; The following table shows how various depth settings affect printing of 'var': | Depth Setting | Result of 'p var' | |---------------+--------------------------------| | Unlimited | $1 = {d = {c = {b = {a = 3}}}} | | 4 | $1 = {d = {c = {b = {a = 3}}}} | | 3 | $1 = {d = {c = {b = {...}}}} | | 2 | $1 = {d = {c = {...}}} | | 1 | $1 = {d = {...}} | | 0 | $1 = {...} | Only structures, unions, and arrays are replaced in this way, scalars and strings are not replaced. The replacement is counted from the level at which you print, not from the top level of the structure. So, consider the above example and this GDB session: (gdb) set print max-depth 2 (gdb) p var $1 = {d = {c = {...}}} (gdb) p var.d $2 = {c = {b = {...}}} (gdb) p var.d.c $3 = {b = {a = 3}} Setting the max-depth to 2 doesn't prevent the user from exploring deeper into 'var' by asking for specific sub-fields to be printed. The motivation behind this feature is to try and give the user more control over how much is printed when examining large, complex data structures. The default max-depth of 20 means that there is a change in GDB's default behaviour. Someone printing a data structure with 20 levels of nesting will now see '{...}' instead of their data, they would need to adjust the max depth, or call print again naming a specific field in order to dig deeper into their data structure. If this is considered a problem then we could increase the default, or even make the default unlimited. This commit relies on the previous commit, which added a new field to the language structure, this new field was a string that contained the pattern that should be used when a structure/union/array is replaced in the output, this allows languages to use a syntax that is more appropriate, mostly this will be selecting the correct types of bracket '(...)' or '{...}', both of which are currently in use. This commit should have no impact on MI output, expressions are printed through the MI using -var-create and then -var-list-children. As each use of -var-list-children only ever displays a single level of an expression then the max-depth setting will have no impact. This commit also adds the max-depth mechanism to the scripting language pretty printers following basically the same rules as for the built in value printing. One quirk is that when printing a value using the display hint 'map', if the keys of the map are structs then GDB will hide the keys one depth level after it hides the values, this ensures that GDB produces output like this: $1 = map_object = {[{key1}] = {...}, [{key2}] = {...}} Instead of this less helpful output: $1 = map_object = {[{...}] = {...}, [{...}] = {...}} This is covered by the new tests in gdb.python/py-nested-maps.exp. gdb/ChangeLog: * cp-valprint.c (cp_print_value_fields): Allow an additional level of depth when printing anonymous structs or unions. * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Don't print either the top-level value, or the children if the max-depth is exceeded.

2016-11-08Remove parameter valaddr from la_val_printYao Qi1-6/+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.

This patch adds new strings to generic_val_print_decorations, updates generic_val_print_array to use them, and updates all the existing instances of generic_val_print_decorations. 2016-05-17 Tom Tromey <tom@tromey.com> * valprint.h (struct generic_val_print_array) <array_start, array_end>: New fields. * valprint.c (generic_val_print_array): Add "decorations" parameter. Use "array_start", "array_end". (generic_val_print) <TYPE_CODE_ARRAY>: Update. * p-valprint.c (p_decorations): Update. * m2-valprint.c (m2_decorations): Update. * f-valprint.c (f_decorations): Update. * c-valprint.c (c_decorations): Update.

2013-12-06Fix "info frame" in the outermost frame.Pedro Alves1-0/+3
Doing "info frame" in the outermost frame, when that was indicated by the next frame saying the unwound PC is undefined/not saved, results in error and incomplete output: (gdb) bt #0 thread_function0 (arg=0x0) at threads.c:63 #1 0x00000034cf407d14 in start_thread (arg=0x7ffff7fcb700) at pthread_create.c:309 #2 0x000000323d4f168d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:115 (gdb) frame 2 #2 0x000000323d4f168d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:115 115 call *%rax (gdb) info frame Stack level 2, frame at 0x0: rip = 0x323d4f168d in clone (../sysdeps/unix/sysv/linux/x86_64/clone.S:115); saved rip Register 16 was not saved (gdb) Not saved register values are treated as optimized out values internally throughout. stack.c:frame_info is handing unvailable values, but not optimized out ones. The patch deletes the frame_unwind_caller_pc_if_available wrapper function and instead lets errors propagate to frame_info (it's only user). As frame_unwind_pc now needs to be able to handle and cache two different error scenarios, the prev_pc.p variable is replaced with an enumeration. (FWIW, I looked into making gdbarch_unwind_pc or a variant return struct value's instead, but it results in lots of boxing and unboxing for no real gain -- e.g., the mips and arm implementations need to do computation on the unboxed PC value. Might as well throw an error on first attempt to get at invalid contents.) After the patch, we get: (gdb) info frame Stack level 2, frame at 0x0: rip = 0x323d4f168d in clone (../sysdeps/unix/sysv/linux/x86_64/clone.S:115); saved rip = <not saved> Outermost frame: outermost caller of frame at 0x7ffff7fcafc0 source language asm. Arglist at 0x7ffff7fcafb8, args: Locals at 0x7ffff7fcafb8, Previous frame's sp is 0x7ffff7fcafc8 (gdb) A new test is added. It's based off dw2-reg-undefined.exp, and tweaked to mark the return address (rip) of "stop_frame" as undefined.

2013-10-02Print registers not saved in the frame as "<not saved>" instead of ↵Pedro Alves1-1/+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.

2013-08-27Add options to skip unavailable localsYao Qi1-0/+2
This is the patch to add new option '--skip-unavailable' to MI commands '-stack-list-{locals, arguments, variables}'. This patch extends list_args_or_locals to add a new parameter 'skip_unavailable', and don't list locals or arguments if values are unavailable and 'skip_unavailable' is true. This is inspecting a trace frame (tfind mode), where only a few locals have been collected. -stack-list-locals, no switch vs new switch: -stack-list-locals --simple-values ^done,locals=[{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}] -stack-list-locals --skip-unavailable --simple-values ^done,locals=[{name="array",type="unsigned char [2]"}] -stack-list-arguments, no switch vs new switch: -stack-list-arguments --simple-values ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"},{name="s",type="char *",value="<unavailable>"}]},frame={level="1",args=[]}] -stack-list-arguments --skip-unavailable --simple-values ^done,stack-args=[frame={level="0",args=[{name="j",type="int",value="4"}]},frame={level="1",args=[]}] -stack-list-variables, no switch vs new switch: -stack-list-variables --simple-values ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="s",arg="1",type="char *",value="<unavailable>"},{name="array",type="unsigned char [2]"},{name="i",type="int",value="<unavailable>"}] -stack-list-variables --skip-unavailable --simple-values ^done,variables=[{name="j",arg="1",type="int",value="4"},{name="array",type="unsigned char [2]"}] tests are added to test these new options. gdb: 2013-08-27 Pedro Alves <pedro@codesourcery.com> Yao Qi <yao@codesourcery.com> * mi/mi-cmd-stack.c (list_args_or_locals): Adjust prototype.
