2013-11-27Make "set debug frame 1" use the standard print routine for optimized out ↵Andrew Burgess1-1/+4
values. ... - { frame_unwind_register_value (frame=0,regnum=7(rsp),...) -> optimized out } + { frame_unwind_register_value (frame=0,regnum=7(rsp),...) -> <optimized out> } ... Tested on x86_64 Fedora 17. 2013-11-27 Andrew Burgess <aburgess@broadcom.com> * frame.c: Include "valprint.h". (frame_unwind_register_value): Use value_optimized_out. * value.c (value_fetch_lazy): Likewise.
2013-11-26Mark entirely optimized out value as non-lazy.Andrew Burgess1-1/+1
If a value is entirely optimized out, then there's nothing for value_fetch_lazy to fetch. Sequences like: if (value_lazy (retval)) value_fetch_lazy (retval); End up allocating the value contents buffer, wasting memory, for no use. gdb/ChangeLog 2013-11-26 Andrew Burgess <aburgess@broadcom.com> * value.c (allocate_optimized_out_value): Mark value as non-lazy.
2013-11-22Detect infinite loop in value_fetch_lazy's lval_register handling.Tom Tromey1-1/+19
If value_fetch_lazy loops infinitely while unwrapping lval_register values, it means we either somehow ended up with two frames with the same ID in the frame chain, or some code is trying to unwind behind get_prev_frame's back (e.g., a frame unwind sniffer trying to unwind). In any case, it should always be an internal error to end up in this situation. This patch adds a check and throws an internal error if the same frame is returned. 2013-11-22 Tom Tromey <tromey@redhat.com> Pedro Alves <palves@redhat.com> PR backtrace/16155 * value.c (value_fetch_lazy): Internal error if get_frame_register_value returns the same register.

2013-10-25Print nonexisting/optimized out static fields gracefully.Pedro Alves1-3/+2
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). Tested on x86_64 Fedora 17. gdb/ 2013-10-25 Pedro Alves <palves@redhat.com> * cp-valprint.c (cp_print_value_fields): No longer handle a NULL static field value.

2013-10-02Print registers not saved in the frame as "<not saved>" instead of ↵Pedro Alves1-3/+19
"<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.

<https://sourceware.org/ml/gdb-patches/2013-09/msg00301.html> <https://sourceware.org/ml/gdb-patches/2013-09/msg00383.html> This patch adds a new convenience function called $_isvoid, whose only purpose is to check whether an expression is void or not. This became necessary because the new convenience variable $_exitsignal (not yet approved) has a mutual exclusive behavior with $_exitcode, i.e., when one is "defined" (i.e., non-void), the other is cleared (i.e., becomes void). Doug wanted a way to identify which variable to use, and checking for voidness is the obvious solution. It is worth mentioning that my first attempt, after a conversation with Doug, was to actually implement a new $_isdefined() convenience function. I would do that (for convenience variables) by calling lookup_only_internalvar. However, I found a few problems: - Whenever I called $_isdefined ($variable), $variable became defined (with a void value), and $_isdefined always returned true. - Then, I tried to implement $_isdefined ("variable"), and do the "$" + "variable" inside GDB, thus making it impossible for GDB to create the convenience variable. However, it was hard to extract the string without having to mess with values and their idiossincrasies. Therefore, I decided to abandon this attempt (specially because I didn't want to spend too much time struggling with it). Anyway, after talking to Doug again we decided that it would be easier to implement $_isvoid, and this will probably help in cases like <http://stackoverflow.com/questions/3744554/testing-if-a-gdb-convenience-variable-is-defined>. I wrote a NEWS entry for it, and some new lines on the documentation. gdb/ 2013-09-16 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS: Mention new convenience function $_isvoid. * value.c (isvoid_internal_fn): New function.

2013-08-05remove msymbol_objfileTom Tromey1-6/+6
This is another patch in my ongoing series to "split" objfile to share more read-only data across inferiors. See http://sourceware.org/gdb/wiki/ObjfileSplitting When symbols are finally shared, there will be no back-link from the symbol to its containing objfile, because there may be more than one such objfile. So, all such back-links must be removed. One hidden back-link is the msymbol_objfile function. Since (eventually) a symbol may appear in more than one objfile, trying to look up the objfile given just a symbol cannot work. This patch removes msymbol_objfile in favor of using a bound minimal symbol. It introduces a new function to make this conversion simpler in some spots. The bonus of this patch is that using msymbol_objfile is slower than simply looking up the owning objfile in the first place.

2013-07-10ada-lang.c:coerce_unspec_val_to_type: Preserve laziness.Joel Brobecker1-0/+6
ada-lang.c:coerce_unspec_val_to_type does: if (value_lazy (val) || TYPE_LENGTH (type) > TYPE_LENGTH (value_type (val))) result = allocate_value_lazy (type); else { result = allocate_value (type); memcpy (value_contents_raw (result), value_contents (val), TYPE_LENGTH (type)); } set_value_component_location (result, val); set_value_bitsize (result, value_bitsize (val)); set_value_bitpos (result, value_bitpos (val)); set_value_address (result, value_address (val)); set_value_optimized_out (result, value_optimized_out (val)); Notice that before value_optimized_out was made to auto-fetch lazy values, VAL would end up still lazy if it was lazy on entry. It's not really a problem here if VAL is lazy, and VAL->optimized_out is 0, because RESULT is also left lazy. IOW, this just wants to copy the VAL->optimized_out flag to RESULT->optimized_out, nothing else. As a side-effect of the change in value_optimized_out, the following testcase now regresses. Consider: type Small is range -64 .. 63; for Small'Size use 7; type Arr is array (1..10) of Small; pragma Pack (Arr); type Arr_Ptr is access Arr; An_Arr_Ptr : Arr_Ptr := new Arr'(10, 20, 30, 40, 50, 60, 62, 63, -23, 42); Trying to print one element of An_Arr_Ptr yields: (gdb) p an_arr_ptr(3) Cannot access memory at address 0x0 The patch adds the value_optimized_out_const function for that, allowing us to avoid trying to fetch a value at a dummy address. (I found this out by grepping for set_value_optimized_out and trying to convert the uses I found to instead allocate the value with allocate_optimized_out_value.)

Doing something else, I factored out the bits of the value_bits_valid function that actually handle the check_validity hook, and surprisingly found out that the result was misbehaving. Turns out value_bits_valid has a latent bug. If the value is not lval_computed, or doesn't have a check_validity hook, then we should assume the value is entirely valid, not invalid. This is currently masked by the value->optimized_out check -- I ran the testsuite with a gdb_assert(0) inserted in place of that return being touched by the patch, and it never triggers.

2013-03-13Constify strings in tracepoint.c, lookup_cmd and the completers.Pedro Alves1-1/+1
This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

2012-03-16[Ada] Crash when trying to set value of packed array elementJoel Brobecker1-1/+12
Consider the following declaration: type Small is new Integer range 0 .. 2 ** 4 - 1; type Simple_Array is array (1 .. 4) of Small; pragma Pack (Simple_Array); SA : Simple_Array := (1, 2, 3, 4); Trying to change the value of one of the elements in the packed array causes the debugger to crash: (gdb) set sa(3) := 9 [1] 4880 segmentation fault gdb -q foo The circumstances leading to the crash are as follow: . ada_evaluate_subexp creates a value corresponding to "sa(3)". . ada_evaluate_subexp then tries to assign 9 to this value, and for this calls value_assign (via ada_value_assign). . Because the array is packed, the destination value is 3 bits long, and as a result, value_assign uses the parent to determine that element byte address and offset: | if (value_bitsize (toval)) | { | struct value *parent = value_parent (toval); | | changed_addr = value_address (parent) + value_offset (toval); The destination value (corresponding to "sa(3)") was incorrectly created by ada-lang.c:ada_value_primitive_packed_val, because the "parent" was left as NULL. So, when we try to dereference it to get the parent address, GDB crashed. The first part of the fix therefore consists in setting that field. This required the addition of a new "setter" in value.[hc]. It fixes the crash, but is still not sufficient for the assignment to actually work. The second part of the problem came from the fact that value_assign seems to expect the "child"'s address to be equal to the parent's address, with the difference being the offset. Unfortunately, this requirement was not followed by ada_value_primitive_packed_val, so the second part of the fix consisted in fixing that. Still, this was not sufficient, because it caused a regression when trying to perform an aggregate assignment of a packed array of packed record. The key element here is the nesting of packed entities. Looking at the way ada_value_primitive_packed_val creates the value of each sub-component, one can see that the value's offset is set to the offset compared to the start of the parent. This was meant to match what value_primitive_field does as well. So, with our array of records, if the record offset was 2, and if the field we're interested in that record is at offset 1, the record value's offset would be set to 2, and the field value's offset would be set to 1. But the address for both values would be left to the array's address. This is where things start breaking down, because the value_address function for our field value would return the address of the array + 1, instead of + 3. This is what causes the final issue, here, because ada-lang.c's value_assign_to_component needs to compute the offset of the subcomponent compared to the top-level aggregate's start address (the array in our case). And it does so by subtracting the array's address from the sub-component's address. When you have two levels of packed components, and the mid-level component is at an offset of the top-level component, things didn't work, because the component's address was miscomputed (the parent's offset is missing). The fix consists is fixing value_address to match the work done by value_primitive_field (where we ignore the parent's offset). gdb/ChangeLog: * value.h (set_value_parent): Add declaration. * value.c (set_value_parent): New function. (value_address): If VALUE->PARENT is not NULL, then use it as the base address instead of VALUE->LOCATION.address. * ada-lang.c (ada_value_primitive_packed_val): Keep V's address the same as OBJ's address. Adjust V's offset accordingly. Set V's parent. gdb/testsuite/ChangeLog: * gdb.ada/set_pckd_arr_elt: New testcase.
