Clean up includes of doublest.h and floatformat.h
As a first small step to getting rid of doublest.h, this patch removes the include of "floatformat.h" in "doublest.h". This is actually not needed for the file itself. A few source files now need to include "floatformat.h" directly, since they got it indirectly via "doublest.h" and still need it. In reviewing which files need it, I found a number of files that include "floatformat.h" directly without actually needing it at all. Similarly, a number of files include "doublest.h" without needing it. I've also removed those unnecessary include statements. gdb/ChangeLog: 2017-10-05 Ulrich Weigand <uweigand@de.ibm.com> * doublest.h: Do not include "floatformat.h". Remove stale comments. * gdbtypes.c: Include "floatformat.h". * value.c: Likewise. * m68k-tdep.c: Likewise. * findvar.c: Do not include "floatformat.h". * amd64-darwin-tdep.c: Likewise. * arm-linux-tdep.c: Likewise. * i386-darwin-tdep.c: Likewise. * i387-tdep.c: Likewise. * m68k-linux-tdep.c: Likewise. * mep-tdep.c: Likewise. * mips-tdep.c: Likewise. * nios2-tdep.c: Likewise. * s390-linux-tdep.c: Likewise. * sparc-obsd-tdep.c: Likewise. * sparc-tdep.c: Likewise. * sparc64-tdep.c: Likewise. * spu-tdep.c: Likewise. * tic6x-tdep.c: Likewise. * tilegx-tdep.c: Likewise. * vax-tdep.c: Likewise. * xstormy16-tdep.c: Likewise. * xtensa-tdep.c: Likewise. * top.c: Do not include "doublest.h". * aarch64-tdep.c: Likewise. * alpha-tdep.c: Likewise. * arm-linux-tdep.c: Likewise. * m68k-linux-tdep.c: Likewise. * tilegx-tdep.c: Likewise. * xstormy16-tdep.c: Likewise. |

Add selftests run filtering
With the growing number of selftests, I think it would be useful to be able to run only a subset of the tests. This patch associates a name to each registered selftest. It then allows doing something like: (gdb) maintenance selftest aarch64 Running self-tests. Running selftest aarch64-analyze-prologue. Running selftest aarch64-process-record. Ran 2 unit tests, 0 failed or with gdbserver: ./gdbserver --selftest=aarch64 In both cases, only the tests that contain "aarch64" in their name are ran. To help validate that the tests you want to run were actually ran, it also prints a message with the test name before running each test. Right now, all the arch-dependent tests are registered as a single test of the selftests. To be able to filter those too, I made them "first-class citizen" selftests. The selftest type is an interface, with different implementations for "simple selftests" and "arch selftests". The run_tests function simply iterates on that an invokes operator() on each test. I changed the tests data structure from a vector to a map, because - it allows iterating in a stable (alphabetical) order - it allows to easily verify if a test with a given name has been registered, to avoid duplicates There's also a new command "maintenance info selftests" that lists the registered selftests. gdb/ChangeLog: * common/selftest.h (selftest): New struct/interface.

extract/store integer function template
This patch converts functions extract_{unsigned,signed}_integer to a function template extract_integer, which has two instantiations. It also does the similar changes to store__{unsigned,signed}_integer, regcache::raw_read_{unsigned,signed}, regcache::raw_write_{unsigned,signed}, regcache::cooked_read_{unsigned,signed}, regcache::cooked_write_{unsigned,signed}. This patch was posted here https://sourceware.org/ml/gdb-patches/2017-05/msg00492.html but the problem was fixed in a different way. However, I think the patch is still useful to shorten the code. gdb: 2017-06-16 Alan Hayward <alan.hayward@arm.com> Pedro Alves <palves@redhat.com> Yao Qi <yao.qi@linaro.org> * defs.h (RequireLongest): New.

Convert lvalue reference type check to general reference type check
In almost all contexts (except for overload resolution rules and expression semantics), lvalue and rvalue references are equivalent. That means that in all but these cases we can replace a TYPE_CODE_REF check to a TYPE_IS_REFERENCE check and, for switch statements, add a case label for a rvalue reference type next to a case label for an lvalue reference type.

Change meaning of VALUE_FRAME_ID; rename to VALUE_NEXT_FRAME_ID
The VALUE_FRAME_ID macro provides access to a member in struct value that's used to hold the frame id that's used when determining a register's value or when assigning to a register. The underlying member has a long and obscure name. I won't refer to it here, but will simply refer to VALUE_FRAME_ID as if it's the struct value member instead of being a convenient macro. At the moment, without this patch in place, VALUE_FRAME_ID is set in value_of_register_lazy() and several other locations to hold the frame id of the frame passed to those functions. VALUE_FRAME_ID is used in the lval_register case of value_fetch_lazy(). To fetch the register's value, it calls get_frame_register_value() which, in turn, calls frame_unwind_register_value() with frame->next. A python based unwinder may wish to determine the value of a register or evaluate an expression containing a register. When it does this, value_fetch_lazy() will be called under some circumstances. It will attempt to determine the frame id associated with the frame passed to it. In so doing, it will end up back in the frame sniffer of the very same python unwinder that's attempting to learn the value of a register as part of the sniffing operation. This recursion is not desirable. As noted above, when value_fetch_lazy() wants to fetch a register's value, it does so (indirectly) by unwinding from frame->next. With this in mind, a solution suggests itself: Change VALUE_FRAME_ID to hold the frame id associated with the next frame. Then, when it comes time to obtain the value associated with the register, we can simply unwind from the frame corresponding to the frame id stored in VALUE_FRAME_ID. This neatly avoids the python unwinder recursion problem by changing when the "next" operation occurs. Instead of the "next" operation occuring when the register value is fetched, it occurs earlier on when assigning a frame id to VALUE_FRAME_ID. (Thanks to Pedro for this suggestion.) This patch implements this idea. It builds on the patch "Distinguish sentinel frame from null frame". Without that work in place, it's necessary to check for null_id at several places and then obtain the sentinel frame. It also renames most occurences of VALUE_FRAME_ID to VALUE_NEXT_FRAME_ID to reflect the new meaning of this field. There are several uses of VALUE_FRAME_ID which were not changed. In each case, the original meaning of VALUE_FRAME_ID is required to get correct results. In all but one of these uses, either put_frame_register_bytes() or get_frame_register_bytes() is being called with the frame value obtained from VALUE_FRAME_ID. Both of these functions perform some unwinding by performing a "->next" operation on the frame passed to it. If we were to use the new VALUE_NEXT_FRAME_ID macro, this would effectively do two "->next" operations, which is not what we want. The VALUE_FRAME_ID macro has been redefined in terms of VALUE_NEXT_FRAME_ID. It simply fetches the previous frame's id, providing this id as the value of the macro. gdb/ChangeLog: * value.h (VALUE_FRAME_ID): Rename to VALUE_NEXT_FRAME_ID. Update comment. Create new VALUE_FRAME_ID which is defined in terms of VALUE_NEXT_FRAME_ID. (deprecated_value_frame_id_hack): Rename to deprecated_value_next_frame_id_hack. * dwarf2loc.c, findvar.c, frame-unwind.c, sentinel-frame.c, valarith.c, valops.c, value.c: Adjust nearly all occurences of VALUE_FRAME_ID to VALUE_NEXT_FRAME_ID.

PR python/20190 - compute TLS symbol without a frame
PR python/20190 arose from an exception I noticed when trying to use the Python unwinder for Spider Monkey in Firefox. The problem is that the unwinder wants to examine the value of a thread-local variable. However, sympy_value rejects this because symbol_read_needs_frame returns true for a TLS variable. This problem arose once before, though in a different context: https://sourceware.org/bugzilla/show_bug.cgi?id=11803 At the time Pedro and Daniel pointed out a simpler way to fix that bug (see links in 20190 if you are interested); but for this new bug I couldn't think of a similar fix and ended up implementing Daniel's other suggestion: https://sourceware.org/ml/gdb-patches/2010-07/msg00393.html That is, this patch makes it possible to detect whether a symbol needs a specific frame, or whether it just needs the inferior to have registers.

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

DWARF: handle non-local references in nested functions
GDB's current behavior when dealing with non-local references in the context of nested fuctions is approximative: - code using valops.c:value_of_variable read the first available stack frame that holds the corresponding variable (whereas there can be multiple candidates for this); - code directly relying on read_var_value will instead read non-local variables in frames where they are not even defined. This change adds the necessary context to symbol reads (to get the block they belong to) and to blocks (the static link property, if any) so that GDB can make the proper decisions when dealing with non-local varibale references. gdb/ChangeLog: * ada-lang.c (ada_read_var_value): Add a var_block argument and pass it to default_read_var_value. * block.c (block_static_link): New accessor. * block.h (block_static_link): Declare it. * buildsym.c (finish_block_internal): Add a static_link argument. If there is a static link, associate it to the new block. (finish_block): Add a static link argument and pass it to finish_block_internal. (end_symtab_get_static_block): Update calls to finish_block and to finish_block_internal. (end_symtab_with_blockvector): Update call to finish_block_internal. * buildsym.h: Forward-declare struct dynamic_prop. (struct context_stack): Add a static_link field. (finish_block): Add a static link argument. * c-exp.y: Remove an obsolete comment (evaluation of variables already start from the selected frame, and now they climb *up* the call stack) and propagate the block information to the produced expression. * d-exp.y: Likewise. * f-exp.y: Likewise. * go-exp.y: Likewise. * jv-exp.y: Likewise. * m2-exp.y: Likewise. * p-exp.y: Likewise. * coffread.c (coff_symtab_read): Update calls to finish_block. * dbxread.c (process_one_symbol): Likewise. * xcoffread.c (read_xcoff_symtab): Likewise. * compile/compile-c-symbols.c (convert_one_symbol): Promote the "sym" parameter to struct block_symbol, update its uses and pass its block to calls to read_var_value. (convert_symbol_sym): Update the calls to convert_one_symbol. * compile/compile-loc2c.c (do_compile_dwarf_expr_to_c): Update call to read_var_value. * dwarf2loc.c (block_op_get_frame_base): New. (dwarf2_block_frame_base_locexpr_funcs): Implement the get_frame_base method. (dwarf2_block_frame_base_loclist_funcs): Likewise. (dwarf2locexpr_baton_eval): Add a frame argument and use it instead of the selected frame in order to evaluate the expression. (dwarf2_evaluate_property): Add a frame argument. Update call to dwarf2_locexpr_baton_eval to provide a frame in available and to handle the absence of address stack. * dwarf2loc.h (dwarf2_evaluate_property): Add a frame argument. * dwarf2read.c (attr_to_dynamic_prop): Add a forward declaration. (read_func_scope): Record any available static link description. Update call to finish_block. (read_lexical_block_scope): Update call to finish_block. * findvar.c (follow_static_link): New. (get_hosting_frame): New. (default_read_var_value): Add a var_block argument. Use get_hosting_frame to handle non-local references.

Consider addressable memory unit size in various value functions
This patch updates various value handling functions to make them consider the addressable memory unit size of the current architecture. This allows to correctly extract and print values on architectures whose addressable memory unit is not 8 bits. The patch doesn't cover all the code that would ideally need to be adjusted, only the code paths that we happen to use, plus a few obvious ones. Specifically, those areas are not covered by this patch: - Management of unavailable bits - Bitfields - C++ stuff Regression-tested on x86-64 Ubuntu 14.04. I saw no related test result change. gdb/ChangeLog: * c-valprint.c (c_val_print_array): Consider addressable memory unit size. (c_val_print_ptr): Likewise.

Add valaddr support in dynamic property resolution.
This is the second part of enhancing the debugger to print the value of arrays of records whose size is variable when only standard DWARF info is available (no GNAT encoding). For instance: subtype Small_Type is Integer range 0 .. 10; type Record_Type (I : Small_Type := 0) is record S : String (1 .. I); end record; type Array_Type is array (Integer range <>) of Record_Type; A1 : Array_Type := (1 => (I => 0, S => <>), 2 => (I => 1, S => "A"), 3 => (I => 2, S => "AB")); Currently, GDB prints the following output: (gdb) p a1 $1 = ( The error happens while the ada-valprint module is trying to print the value of an element of our array. Because of the fact that the array's element (type Record_Type) has a variant size, the DWARF info for our array provide the array's stride: <1><749>: Abbrev Number: 10 (DW_TAG_array_type) <74a> DW_AT_name : (indirect string, offset: 0xb6d): pck__T18s <74e> DW_AT_byte_stride : 16 <74f> DW_AT_type : <0x6ea> And because our array has a stride, ada-valprint treats it the same way as packed arrays (see ada-valprint.c::ada_val_print_array): if (TYPE_FIELD_BITSIZE (type, 0) > 0) val_print_packed_array_elements (type, valaddr, offset_aligned, 0, stream, recurse, original_value, options); The first thing that we should notice in the call above is that the "valaddr" buffer and the associated offset (OFFSET_ALIGNED) is passed, but that the corresponding array's address is not. This can be explained by looking inside val_print_packed_array_elements, where we see that the function unpacks each element of our array from the buffer alone (ada_value_primitive_packed_val), and then prints the resulting artificial value instead: v0 = ada_value_primitive_packed_val (NULL, valaddr + offset, (i0 * bitsize) / HOST_CHAR_BIT, (i0 * bitsize) % HOST_CHAR_BIT, bitsize, elttype); [...] val_print (elttype, value_contents_for_printing (v0), value_embedded_offset (v0), 0, stream, recurse + 1, v0, &opts, current_language); Of particular interest, here, is the fact that we call val_print with a null address, which is OK, since we're providing a buffer instead (value_contents_for_printing). Also, providing an address might not always possible, since packing could place elements at boundaries that are not byte-aligned. Things go south when val_print tries to see if there is a pretty-printer that could be applied. In particular, one of the first things that the Python pretty-printer does is to create a value using our buffer, and the given address, which in this case is null (see call to value_from_contents_and_address in gdbpy_apply_val_pretty_printer). value_from_contents_and_address, in turn immediately tries to resolve the type, using the given address, which is null. But, because our array element is a record containing an array whose bound is the value of one of its elements (the "s" component), the debugging info for the array's upper bound is a reference... <3><71a>: Abbrev Number: 7 (DW_TAG_subrange_type) <71b> DW_AT_type : <0x724> <71f> DW_AT_upper_bound : <0x703> ... to component "i" of our record... <2><703>: Abbrev Number: 5 (DW_TAG_member) <704> DW_AT_name : i <706> DW_AT_decl_file : 2 <707> DW_AT_decl_line : 6 <708> DW_AT_type : <0x6d1> <70c> DW_AT_data_member_location: 0 ... where that component is located at offset 0 of the start of the record. dwarf2_evaluate_property correctly determines the offset where to load the value of the bound from, but then tries to read that value from inferior memory using the address that was given, which is null. See case PROP_ADDR_OFFSET in dwarf2_evaluate_property: val = value_at (baton->offset_info.type, pinfo->addr + baton->offset_info.offset); This triggers a memory error, which then causes the printing to terminate. Since there are going to be situations where providing an address alone is not going to be sufficient (packed arrays where array elements are not stored at byte boundaries), this patch fixes the issue by enhancing the type resolution to take both address and data. This follows the same principle as the val_print module, where both address and buffer ("valaddr") can be passed as arguments. If the data has already been fetched from inferior memory (or provided by the debugging info in some form -- Eg a constant), then use that data instead of reading it from inferior memory. Note that this should also be a good step towards being able to handle dynamic types whose value is stored outside of inferior memory (Eg: in a register). With this patch, GDB isn't able to print all of A1, but does perform a little better: (gdb) p a1 $1 = ((i => 0, s => , (i => 1, s => , (i => 2, s => ) There is another issue which is independent of this one, and will therefore be patched separately. gdb/ChangeLog: * dwarf2loc.h (struct property_addr_info): Add "valaddr" field. * dwarf2loc.c (dwarf2_evaluate_property): Add handling of pinfo->valaddr. * gdbtypes.h (resolve_dynamic_type): Add "valaddr" parameter. * gdbtypes.c (resolve_dynamic_struct): Set pinfo.valaddr.

Support gdbarch_convert_register_p targets in address_from_register
Since the last change to address_from_register, it no longer supports targets that require a special conversion (gdbarch_convert_register_p) for plain pointer type; I had assumed no target does so. This turned out to be incorrect: MIPS64 n32 big-endian needs such a conversion in order to properly sign-extend pointer values. This patch fixes this regression by handling targets that need a special conversion in address_from_register as well. gdb/ChangeLog: * findvar.c (address_from_register): Handle targets requiring a special conversion routine even for plain pointer types. |

Use address_from_register in dwarf2-frame.c:read_addr_from_reg
This patch fixes a problem that prevented use of the Dwarf unwinders on SPU, because dwarf2-frame.c common code did not support the situation where the stack and/or frame pointer is maintained in a *vector* register. This is because read_addr_from_reg is hard-coded to assume that such pointers can be read from registers via a simple get_frame_register / unpack_pointer operation. Now, there *is* a routine address_from_register that calls into the appropriate tdep routines to handle pointer values in "weird" registers like on SPU, but it turns out I cannot simply change dwarf2-frame.c to use address_from_register. This is because address_from_register uses value_from_register to create a (temporary) value, and that routine at some point calls get_frame_id in order to set up that value's VALUE_FRAME_ID entry. However, the dwarf2-frame.c read_addr_from_reg routine will be called during early unwinding (to unwind the frame's CFA), at which point the frame's ID is not actually known yet! This would cause an assert. On the other hand, we may notice that VALUE_FRAME_ID is only needed in the value returned by value_from_register if that value is later used as an lvalue. But this is obviously never done to the temporary value used in address_from_register. So, if we could change address_from_register to not call value_from_register but instead accept constructing a value that doesn't have VALUE_FRAME_ID set, things should be fine. To do that, we can change the value_from_register callback to accept a FRAME_ID instead of a FRAME; the only existing uses of the FRAME argument were either to extract its frame ID, or its gdbarch. (To keep a way of getting at the latter, we also change the callback's type from "f" to "m".) Together with the required follow-on changes in the existing value_from_register implementations (including the default one), this seems to fix the problem. As another minor interface cleanup, I've removed the explicit TYPE argument from address_from_register. This routine really always uses a default pointer type, and in the new implementation it -to some extent- relies on that fact, in that it will now no longer handle types that require gdbarch_convert_register_p handling. gdb: 2014-04-17 Ulrich Weigand <uweigand@de.ibm.com> * gdbarch.sh (value_from_register): Make class "m" instead of "f". Replace FRAME argument with FRAME_ID. * gdbarch.c, gdbarch.h: Regenerate. * findvar.c (default_value_from_register): Add GDBARCH argument; replace FRAME by FRAME_ID. No longer call get_frame_id.

Do not call value_from_register; use gdbarch_value_from_register with null_frame_id instead. * value.h (address_from_register): Update prototype. * dwarf2-frame.c (read_addr_from_reg): Use address_from_register. * dwarf2loc.c (dwarf_expr_read_addr_from_reg): Update for address_from_register interface change. |

start change to progspace independence
This patch starts changing minimal symbols to be independent of the program space. Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS and changes all the code to use it. This is needed so we can change gdb to apply the section offset when a minsym's address is computed, as opposed to baking the offsets into the symbol itself. A few spots still need the unrelocated address. For these, we introduce MSYMBOL_VALUE_RAW_ADDRESS. As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS, which computes the address of a bound minimal symbol. This just does the obvious thing with the fields. Note that this change does not actually enable program space independence. That requires more changes to gdb. However, to ensure that these changes compile properly, this patch does add the needed section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has no effect at runtime by multiplying the offset by 0. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_main_name): Update.

use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found.

change minsym representation
In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

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.

Rework value_of_register in terms of value_of_register_lazy.
I noticed that value_of_register (used for getting values _of_ registers ($pc, $rax, etc.), rather than variables _in_ registers), kind of builds a franken-value, by propagating the lval and address of the frame register value, but not the entire location, like necessary for lval_computed (if some unwinder ever returns that, the resulting value will misbehave). This gets in the way of printing optimized out (not saved) lval_registers differently from other optimized out values, as it doesn't make sure the resulting value is lval_register. I started out by just doing something like: - VALUE_LVAL (reg_val) = lval; - set_value_address (reg_val, addr); + VALUE_LVAL (reg_val) = lval_register; ... just like value_of_register_lazy below. That's sufficient to fix the issue. Then I noticed this is using frame_register, which we should avoid nowadays, for it returns elements of a value, but not all that's sometimes necessary (unavailable-ness is all or nothing with it, for instance), and considered using get_frame_register_value instead (which returns a struct value), and value_contents_copy, just like value_fetch_lazy's handling of lval_register. But at that point, I realized we might as well just defer all that work to value_of_register_lazy/value_fetch_lazy... Doing it this way adds a frame_find_by_id lookup (from within value_fetch_lazy), while we already have a frame pointer handy in value_of_register. I considered factoring out the lazy register fetching out of value_fetch_lazy, into a function that takes a frame pointer and call that instead, avoiding the lookup, but then it looked like too much complication for an early optimization, and went back to keeping it simple. Tested on x86_64 Fedora 17. gdb/ 2013-09-05 Pedro Alves <palves@redhat.com> * findvar.c (value_of_register): Rework in terms of value_of_register_lazy. |

cleanup: use value_lazy_at instead of allocate_value_lazy/attribute setter
I came across a pattern used to construct a value in the following way: struct value *val = allocate_value_lazy (type); VALUE_LVAL (val) = lval_memory; set_value_address (val, address); Instead we fold the above call into: value_at_lazy (type, addr); 2013-08-27 Sanimir Agovic <sanimir.agovic@intel.com> * dwarf2loc.c (dwarf2_evaluate_loc_desc_full): Use value_at_lazy instead of assembling value via allocate_value_lazy and attribute setter. * findvar.c (default_read_var_value): Use value_at_lazy instead of assembling value via allocate_value_lazy and attribute setter. * valops.c (do_search_struct_field): Use value_at_lazy instead of assembling value via allocate_value_lazy and attribute setter. |

New "iterate_over_objfiles_in_search_order" gdbarch method.
This patch introduces the "iterate_over_objfiles_in_search_order" gdbarch method, as well as its default implementation, and converts the areas where it will matter to using this gdbarch method. The default method implementation is the only one installed, and the changes should have no functional impact in terms of behavior. This only paves the way for the architectures that will need their own version. gdb/ChangeLog: * gdbarch.sh: Add generation of "iterate_over_objfiles_in_search_order_cb_ftype" typedef in gdbarch.h. Add include of "objfiles.h" in gdbarch.c. (iterate_over_objfiles_in_search_order): New gdbarch method. * gdbarch.h, gdbarch.c: Regenerate. * objfiles.h (default_iterate_over_objfiles_in_search_order): Add declaration. * objfiles.c (default_iterate_over_objfiles_in_search_order): New function. * symtab.c (lookup_symbol_aux_objfile): New function, extracted out of lookup_symbol_aux_symtabs.

language-specific read_var_value for Ada renamings
The purpose of this patch is to better support renamings in the "info locals" command. Consider ... procedure Foo is GV : Integer renames Pck.Global_Variable; begin Increment (GV); -- STOP end Foo; ... Pck.Global_Variable is just an integer. After having stopped at the "STOP" line, "info locals" yields: (gdb) info locals gv = <error reading variable gv (Cannot access memory at address 0xffffffffffffffff)> In reality, two things are happening: (1) Variable "GV" does not exist, which is normal, since there is "GV" the renaming of another variable; (2) But to allow the user access to that renaming the same way the code has, the compiler produces an artificial variable whose name encodes the renaming: gv___XR_pck__global_variable___XE For practical reasons, the artificial variable itself is given irrelevant types and addresses. But the "info locals" command does not act as if it was a short-cut of "foreach VAR in locals, print VAR". Instead it gets the value of each VAR directly, which does not work in this case, since the variable is artificial and needs to be decoded first. This patch makes the "read_var_value" routine language-specific. The old implementation of "read_var_value" gets renamed to "default_read_var_value" and all languages now use it (unchanged behavior), except for Ada. In Ada, the new function ada_read_var_value checks if we have a renaming, and if so, evaluates its value, or else defers to default_read_var_value. gdb/ChangeLog: * language.h (struct language_defn): New "method" la_read_var_value. * findvar.c: #include "language.h". (default_read_var_value): Renames read_var_value. Rewrite function description. (read_var_value): New function. * value.h (default_read_var_value): Add prototype. * ada-lang.c (ada_read_renaming_var_value, ada_read_var_value): New functions.
