gdb/ChangeLog: Update copyright year range in all GDB files.
2019-04-22Support for DW_OP_addrx and DW_FORM_addrx tagsAli Tamur1-2/+3
DW_OP_addrx is the new name of DW_OP_GNU_addr_index, and DW_FORM_addrx is the name of DW_FORM_addr_index in the Dwarf 5 standard. This is a small step towards supporting Dwarf 5 in gdb. Note: I could not find any tests specifically for *_GNU_addr_index, and I did not add any new tests, please advise.
2019-04-06Revert the header-sorting patchTom Tromey1-1/+1
Andreas Schwab and John Baldwin pointed out some bugs in the header sorting patch; and I noticed that the output was not correct when limited to a subset of files (a bug in my script). So, I'm reverting the patch. I may try again after fixing the issues pointed out. gdb/ChangeLog 2019-04-05 Tom Tromey <tom@tromey.com> Revert the header-sorting patch. * ft32-tdep.c: Revert. * frv-tdep.c: Revert. * frv-linux-tdep.c: Revert. * frame.c: Revert. * frame-unwind.c: Revert. * frame-base.c: Revert. * fork-child.c: Revert. * findvar.c: Revert. * findcmd.c: Revert. * filesystem.c: Revert. * filename-seen-cache.h: Revert. * filename-seen-cache.c: Revert. * fbsd-tdep.c: Revert. * fbsd-nat.h: Revert. * fbsd-nat.c: Revert. * f-valprint.c: Revert. * f-typeprint.c: Revert. * f-lang.c: Revert. * extension.h: Revert. * extension.c: Revert. * extension-priv.h: Revert. * expprint.c: Revert. * exec.h: Revert. * exec.c: Revert. * exceptions.c: Revert. * event-top.c: Revert. * event-loop.c: Revert. * eval.c: Revert. * elfread.c: Revert. * dwarf2read.h: Revert. * dwarf2read.c: Revert. * dwarf2loc.c: Revert. * dwarf2expr.h: Revert. * dwarf2expr.c: Revert. * dwarf2-frame.c: Revert. * dwarf2-frame-tailcall.c: Revert. * dwarf-index-write.h: Revert. * dwarf-index-write.c: Revert. * dwarf-index-common.c: Revert. * dwarf-index-cache.h: Revert. * dwarf-index-cache.c: Revert. * dummy-frame.c: Revert. * dtrace-probe.c: Revert. * disasm.h: Revert. * disasm.c: Revert. * disasm-selftests.c: Revert. * dictionary.c: Revert. * dicos-tdep.c: Revert. * demangle.c: Revert. * dcache.h: Revert. * dcache.c: Revert. * darwin-nat.h: Revert. * darwin-nat.c: Revert. * darwin-nat-info.c: Revert. * d-valprint.c: Revert. * d-namespace.c: Revert. * d-lang.c: Revert. * ctf.c: Revert. * csky-tdep.c: Revert. * csky-linux-tdep.c: Revert. * cris-tdep.c: Revert. * cris-linux-tdep.c: Revert. * cp-valprint.c: Revert. * cp-support.c: Revert. * cp-namespace.c: Revert. * cp-abi.c: Revert. * corelow.c: Revert. * corefile.c: Revert. * continuations.c: Revert. * completer.h: Revert. * completer.c: Revert. * complaints.c: Revert. * coffread.c: Revert. * coff-pe-read.c: Revert. * cli-out.h: Revert. * cli-out.c: Revert. * charset.c: Revert. * c-varobj.c: Revert. * c-valprint.c: Revert. * c-typeprint.c: Revert. * c-lang.c: Revert. * buildsym.c: Revert. * buildsym-legacy.c: Revert. * build-id.h: Revert. * build-id.c: Revert. * btrace.c: Revert. * bsd-uthread.c: Revert. * breakpoint.h: Revert. * breakpoint.c: Revert. * break-catch-throw.c: Revert. * break-catch-syscall.c: Revert. * break-catch-sig.c: Revert. * blockframe.c: Revert. * block.c: Revert. * bfin-tdep.c: Revert. * bfin-linux-tdep.c: Revert. * bfd-target.c: Revert. * bcache.c: Revert. * ax-general.c: Revert. * ax-gdb.h: Revert. * ax-gdb.c: Revert. * avr-tdep.c: Revert. * auxv.c: Revert. * auto-load.c: Revert. * arm-wince-tdep.c: Revert. * arm-tdep.c: Revert. * arm-symbian-tdep.c: Revert. * arm-pikeos-tdep.c: Revert. * arm-obsd-tdep.c: Revert. * arm-nbsd-tdep.c: Revert. * arm-nbsd-nat.c: Revert. * arm-linux-tdep.c: Revert. * arm-linux-nat.c: Revert. * arm-fbsd-tdep.c: Revert. * arm-fbsd-nat.c: Revert. * arm-bsd-tdep.c: Revert. * arch-utils.c: Revert. * arc-tdep.c: Revert. * arc-newlib-tdep.c: Revert. * annotate.h: Revert. * annotate.c: Revert. * amd64-windows-tdep.c: Revert. * amd64-windows-nat.c: Revert. * amd64-tdep.c: Revert. * amd64-sol2-tdep.c: Revert. * amd64-obsd-tdep.c: Revert. * amd64-obsd-nat.c: Revert. * amd64-nbsd-tdep.c: Revert. * amd64-nbsd-nat.c: Revert. * amd64-nat.c: Revert. * amd64-linux-tdep.c: Revert. * amd64-linux-nat.c: Revert. * amd64-fbsd-tdep.c: Revert. * amd64-fbsd-nat.c: Revert. * amd64-dicos-tdep.c: Revert. * amd64-darwin-tdep.c: Revert. * amd64-bsd-nat.c: Revert. * alpha-tdep.c: Revert. * alpha-obsd-tdep.c: Revert. * alpha-nbsd-tdep.c: Revert. * alpha-mdebug-tdep.c: Revert. * alpha-linux-tdep.c: Revert. * alpha-linux-nat.c: Revert. * alpha-bsd-tdep.c: Revert. * alpha-bsd-nat.c: Revert. * aix-thread.c: Revert. * agent.c: Revert. * addrmap.c: Revert. * ada-varobj.c: Revert. * ada-valprint.c: Revert. * ada-typeprint.c: Revert. * ada-tasks.c: Revert. * ada-lang.c: Revert. * aarch64-tdep.c: Revert. * aarch64-ravenscar-thread.c: Revert. * aarch64-newlib-tdep.c: Revert. * aarch64-linux-tdep.c: Revert. * aarch64-linux-nat.c: Revert. * aarch64-fbsd-tdep.c: Revert. * aarch64-fbsd-nat.c: Revert. * aarch32-linux-nat.c: Revert.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-08-18Add support for DW_OP_GNU_variable_valueKevin Buettner1-0/+3
This patch adds support for DW_OP_GNU_variable_value to GDB. Jakub Jelinek provides a fairly expansive discussion of this DWARF expression opcode in his GCC patch... https://gcc.gnu.org/ml/gcc-patches/2017-02/msg01499.html It has also been proposed for addition to the DWARF Standard: http://www.dwarfstd.org/ShowIssue.php?issue=161109.2 If compiled with a suitable version of GCC, the test case associated with GCC Bug 77589 uses DW_OP_GNU_variable_value in a DW_AT_byte_stride expression. Here's a link to the bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77589 This is what the DWARF looks like. Look at the last line, which has the DW_AT_byte_stride expression: <2><e1>: Abbrev Number: 12 (DW_TAG_variable) <e2> DW_AT_name : (indirect string, offset: 0x115): span.0 <e6> DW_AT_type : <0x2e> <ea> DW_AT_artificial : 1 <ea> DW_AT_location : 3 byte block: 91 b0 7f (DW_OP_fbreg: -80) ... <2><178>: Abbrev Number: 18 (DW_TAG_subrange_type) <179> DW_AT_lower_bound : 4 byte block: 97 23 20 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 32; DW_OP_deref) <17e> DW_AT_upper_bound : 4 byte block: 97 23 28 6 (DW_OP_push_object_address; DW_OP_plus_uconst: 40; DW_OP_deref) <183> DW_AT_byte_stride : 10 byte block: 97 23 18 6 fd e1 0 0 0 1e (DW_OP_push_object_address; DW_OP_plus_uconst: 24; DW_OP_deref; DW_OP_GNU_variable_value: <0xe1>; DW_OP_mul) A patch to readelf, which I'm also submitting, is required to do this decoding. I found that GDB gave me the correct answer for "p c40pt(2)" once I (correctly) implemented DW_OP_GNU_variable_value. I also have test case (later in this series) which uses the DWARF assembler and, therefore, do not rely on having a compiler with this support. gdb/ChangeLog: * dwarf2expr.h (struct dwarf_expr_context): Add virtual method dwarf_variable_value. * dwarf2-frame.c (class dwarf_expr_executor): Add override for dwarf_variable_value. * dwarf2loc.c (class dwarf_evaluate_loc_desc): Likewise.

(dwarf2_compile_expr_to_ax): Add case for DW_OP_GNU_variable_value. * dwarf2expr.c (dwarf_expr_context::execute_stack_op): Add case for DW_OP_GNU_variable_value.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-09-14Make dwarf_expr_context::stack an std::vectorSimon Marchi1-8/+7
Replace the manually managed array with a vector. It is mostly straightforward, except maybe one thing in execute_stack_op, in the handling of DW_OP_fbreg. When the code stumbles on that opcode while evaluating an expression, it needs to evaluate a subexpression to find where the fb reg has been saved. Rather than creating a new context, it reuses the current context. It saves the size of the stack before and restores the stack to that size after. I think we can do a little bit better by saving the current stack locally and installing a new empty stack. This way, if the subexpression is malformed and underflows, we'll get an exception. Before, it would have overwritten the top elements of the top-level expression. The evaluation of the top-level expression would have then resumed with the same stack size, but possibly some corrupted elements. gdb/ChangeLog: * dwarf2expr.h (dwarf_stack_value): Add constructor. (dwarf_expr_context) <~dwarf_expr_context>: Define as default. <stack>: Change type to std::vector. <stack_len, stack_allocated>: Remove. <grow_stack>: Remove. * dwarf2expr.c (dwarf_expr_context::dwarf_expr_context): Adjust.

2017-09-14Make dwarf_expr_piece::pieces an std::vectorSimon Marchi1-52/+49
Change the manually managed array dwarf_expr_piece::piece with an std::vector. After passing the pieces array to allocate_piece_closure, dwarf2_evaluate_loc_desc_full doesn't need that data anymore. We can therefore move the content of the vector to avoid copying it. Reg-tested on the buildbot. gdb/ChangeLog: * dwarf2expr.h (struct dwarf_expr_piece): Move up. (struct dwarf_expr_context) <n_pieces>: Remove. <pieces>: Change type to std::vector. * dwarf2expr.c (dwarf_expr_context::dwarf_expr_context): Adjust.

2017-04-04Make sect_offset and cu_offset strong typedefs instead of structsPedro Alves1-8/+8
A while ago, back when GDB was a C program, the sect_offset and cu_offset types were made structs in order to prevent incorrect mixing of those offsets. Now that we require C++11, we can make them integers again, while keeping the safety, by exploiting "enum class". We can add a bit more safety, even, by defining operators that the types _should_ support, helping making the suspicious uses stand out more. Getting at the underlying type is done with the new to_underlying function added by the previous patch, which also helps better spot where do we need to step out of the safety net. Mostly, that's around parsing the DWARF, and when we print the offset for complaint/debug purposes. But there are other occasional uses. Since we have to define the sect_offset/cu_offset types in a header anyway, I went ahead and generalized/library-fied the idea of "offset" types, making it trivial to add more such types if we find a use. See common/offset-type.h and the DEFINE_OFFSET_TYPE macro. I needed a couple generaly-useful preprocessor bits (e.g., yet another CONCAT implementation), so I started a new common/preprocessor.h file. I included units tests covering the "offset" types API. These are mostly compile-time tests, using SFINAE to check that expressions that shouldn't compile (e.g., comparing unrelated offset types) really are invalid and would fail to compile. This same idea appeared in my pending enum-flags revamp from a few months ago (though this version is a bit further modernized compared to what I had posted), and I plan on reusing the "check valid expression" bits added here in that series, so I went ahead and defined the CHECK_VALID_EXPR macro in its own header -- common/valid-expr.h. I think that's nicer regardless. I was borderline between calling the new types "offset" types, or "index" types, BTW. I stuck with "offset" simply because that's what we're already calling them, mostly. gdb/ChangeLog: 2017-04-04 Pedro Alves <palves@redhat.com> * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/offset-type-selftests.c. (SUBDIR_UNITTESTS_OBS): Add offset-type-selftests.o. * common/offset-type.h: New file. * common/preprocessor.h: New file. * common/traits.h: New file. * common/valid-expr.h: New file. * dwarf2expr.c: Include "common/underlying.h".

Adjust to use sect_offset and cu_offset strong typedefs throughout. * dwarf2read.c: Adjust to use sect_offset and cu_offset strong typedefs throughout. * gdbtypes.h: Include "common/offset-type.h". (cu_offset): Now an offset type (strong typedef) instead of a struct. (sect_offset): Likewise. (union call_site_parameter_u): Rename "param_offset" field to "param_cu_off". * unittests/offset-type-selftests.c: New file.

2016-11-02Fix dwarf_expr_context method regressionsTom Tromey1-5/+3
This fixes some regressions found in the patch to convert dwarf_expr_context to use methods. Specifically: * get_base_type could erroneously throw; this was rewritten to move the size checks into the only spot needing them. * Previously the "symbol needs frame" implementation reused th "cfa" function for the get_frame_pc slot; this reimplements it under the correct name. * Not enough members were saved and restored in one implementation of push_dwarf_reg_entry_value; this patch fixes this oversight and also takes the opportunity to remove an extraneous structure definition. 2016-11-02 Tom Tromey <tom@tromey.com> * dwarf2loc.c (dwarf_evaluate_loc_desc::get_base_type): Rename from impl_get_base_type. Rewrite. (struct dwarf_expr_baton): Remove. (dwarf_evaluate_loc_desc::push_dwarf_reg_entry_value): Save and restore more fields. (symbol_needs_eval_context::get_frame_pc): New method. * dwarf2expr.h (dwarf_expr_context::get_base_type): Now public, virtual. (dwarf_expr_context::impl_get_base_type): Remove. * dwarf2expr.c (dwarf_expr_context::get_base_type): Remove.

2016-10-21Convert dwarf_expr_context_funcs to methodsTom Tromey1-86/+87
This patch converts the function pointers in dwarf_expr_context_funcs into methods on dwarf_expr_context, and then updates the various implementations and callers to follow. NB this patch uses "override" (which caught a couple of renaming bugs during development) -- but this is C++11, so this patch at least has to wait for Pedro's patch that adds the OVERRIDE macro. After this patch it would be possible to do one more, that makes various members of dwarf_expr_context "protected"; but I haven't done this. 2016-10-21 Tom Tromey <tom@tromey.com> * dwarf2loc.c (struct dwarf_expr_context_funcs): Don't declare.

2016-09-02Handle DW_OP_form_tls_addressTom Tromey1-1/+1
Currently gdb supports DW_OP_GNU_push_tls_address, but not DW_OP_form_tls_address. I think it would be better if the toolchain as a whole moved to using the standard opcode, and the prerequisite to this is getting gdb to recognize it. GCC can sometimes emit DW_OP_form_tls_address for emultls targets. As far as I know, nobody has ever tried this with gdb (since it wouldn't work at all). I don't think there's a major drawback to using a single opcode for all targets, because computing the location of a thread-local is already target specific. This is PR gdb/11616. I don't know how to write a test case for this; though it's worth noting that there aren't explicit tests for DW_OP_GNU_push_tls_address either -- and if I change GCC, these paths will be tested to the same extent they are now. 2016-09-02 Tom Tromey <tom@tromey.com> PR gdb/11616: * dwarf2read.c (decode_locdesc): Handle DW_OP_form_tls_address. * dwarf2loc.c (dwarf2_compile_expr_to_ax): Handle DW_OP_form_tls_address.

2013-11-14Fix DW_OP_GNU_regval_type with FP registersJoel Brobecker1-1/+8
Consider the following code, compiled at -O2 on ppc-linux: procedure Increment (Val : in out Float; Msg : String); The implementation does not really matter in this case). In our example, this function is being called from a function with Param_1 set to 99.0. Trying to break inside that function, and running until reaching that breakpoint yields: (gdb) b increment Breakpoint 1 at 0x100014b4: file callee.adb, line 6. (gdb) run Starting program: /[...]/foo Breakpoint 1, callee.increment (val=99.0, val@entry=0.0, msg=...) at callee.adb:6 6 if Val > 200.0 then The @entry value for parameter "val" is incorrect, it should be 99.0. The associated call-site parameter DIE looks like this: .uleb128 0xc # (DIE (0x115) DW_TAG_GNU_call_site_parameter) .byte 0x2 # DW_AT_location .byte 0x90 # DW_OP_regx .uleb128 0x21 .byte 0x3 # DW_AT_GNU_call_site_value .byte 0xf5 # DW_OP_GNU_regval_type .uleb128 0x3f .uleb128 0x25 The DW_AT_GNU_call_site_value uses a DW_OP_GNU_regval_type operation, referencing register 0x3f=63, which is $f31, an 8-byte floating register. In that register, the value is stored using the usual 8-byte float format: (gdb) info float f31 99.0 (raw 0x4058c00000000000) The current code evaluating DW_OP_GNU_regval_type operations currently is (dwarf2expr.c:execute_stack_op): result = (ctx->funcs->read_reg) (ctx->baton, reg); result_val = value_from_ulongest (address_type, result); result_val = value_from_contents (type, value_contents_all (result_val)); What the ctx->funcs->read_reg function does is read the contents of the register as if it contained an address. The rest of the code continues that assumption, thinking it's OK to then use that to create an address/ulongest struct value, which we then re-type to the type specified by DW_OP_GNU_regval_type. We're getting 0.0 above because the read_reg implementations end up treating the contents of the FP register as an integral, reading only 4 out of the 8 bytes. Being a big-endian target, we read the high-order ones, which gives us zero. This patch fixes the problem by introducing a new callback to read the contents of a register as a given type, and then adjust the handling of DW_OP_GNU_regval_type to use that new callback. gdb/ChangeLog: * dwarf2expr.h (struct dwarf_expr_context_funcs) <read_reg>: Extend the documentation a bit. <get_reg_value>: New field. * dwarf2loc.c (dwarf_expr_get_reg_value) (needs_frame_get_reg_value): New functions.
