gdb: add back declarations for _initialize functions
I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:

Move [PAC] into a new MI field addr_flags
Add a new print_pc which prints both the PC and a new field addr_flags. Call this wherever the PC is printed in stack.c. Add a new gdbarch method get_pc_address_flags to obtain the addr_flag contents. By default returns an empty string, on AArch64 this returns PAC if the address has been masked in the frame. Document this in the manual and NEWS file. gdb/ChangeLog: * NEWS (Other MI changes): New subsection. * aarch64-tdep.c (aarch64_get_pc_address_flags): New function.

AArch64: Allow additional sizes in prologue
When saving registers to the stack at the start of a function, not all state needs to be saved. For example, only the first 64bits of float registers need saving. However, a program may choose to store extra state if it wishes, there is nothing preventing it doing so. The aarch64_analyze_prologue will error if it detects extra state being stored. Relex this restriction. Tested via aarch64-prologue test. gdb/ChangeLog: * aarch64-tdep.c (aarch64_analyze_prologue): Allow any valid register sizes. gdb/testsuite/ChangeLog: * gdb.arch/aarch64-prologue.c: New test. * gdb.arch/aarch64-prologue.exp: New file. |

AArch64 pauth: Indicate unmasked addresses in backtrace
Armv8.3-a Pointer Authentication causes the function return address to be obfuscated on entry to some functions. GDB must unmask the link register in order to produce a backtrace. The following patch adds markers of [PAC] to the bracktrace, to indicate which addresses needed unmasking. This includes the backtrace when using MI. For example, consider the following backtrace: (gdb) bt 0 0x0000000000400490 in puts@plt () 1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6 2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12 3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17 4 0x00000000004005b4 in main () at cbreak-3.c:10 The functions in cbreak-lib use pointer auth, which masks the return address to the previous function, causing the addresses of bar (in the library) and main2 (in the main binary) to require unmasking in order to unwind the backtrace. An extra bool is added alongside the prev_pc in the frame structure. At the point at which the link register is unmasked, the AArch64 port calls into frame to sets the bool. This is the most efficient way of doing it. The marker is also added to the python frame printer, which is always printed if set. The marker is not explicitly exposed to the python code. I expect this will potentially cause issues with some tests in the testsuite when Armv8.3 pointer authentication is used. This should be fixed up in the the future once real hardware is available for full testsuite testing. gdb/ChangeLog: * NEWS: Expand the Pointer Authentication entry. * aarch64-tdep.c (aarch64_frame_unmask_address): Rename from this. (aarch64_frame_unmask_lr): ... to this. (aarch64_prologue_prev_register, aarch64_dwarf2_prev_register): Call aarch64_frame_unmask_lr. * frame.c (struct frame_info): Add "masked" variable.

(fprint_frame): Check for masked pc. * frame.h (frame_set_previous_pc_masked) (frame_get_pc_masked): New declarations. * python/py-framefilter.c (py_print_frame): Check for masked pc. * stack.c (print_frame): Check for masked pc. gdb/doc/ChangeLog: * gdb.texinfo (AArch64 Pointer Authentication): New subsection. |

Don't include gdbarch.h from defs.h
I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise. |

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

i386/AArch64: Remove old xml tests
Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy xml files, dat files and auto generated C files, when building for unit test. These tests exists back from when feature target descriptions were added to prove that the new target descriptions were identical to the original older versions. The old files are not used for anything other than these tests. Now that this has been proven, we are not gaining anything by keeping the original files and tests. Should new functionality be added, it would break the tests, unless the functionality was backported to the xml. There is no requirement that we must match the exact xml from N releases ago. It adds obfuscation, where as the feature target descriptions were meant to simplify the code. In addition, there are a bunch of xml and dat files which are completely unused. This patch removes the selftests and the target descriptions from gdbserver. Update the unittest to allow 0 tests (note, this failed on other targets that never had any tests). gdb/ChangeLog: * aarch64-tdep.c: Remove xml self tests. * amd64-linux-tdep.c: Likewise. * amd64-tdep.c: Likewise. * i386-linux-tdep.c: Likewise. * i386-tdep.c: Likewise. gdb/gdbserver/ChangeLog: * configure.srv: Remove legacy xml. * linux-aarch64-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-aarch64-tdesc-selftest.c: Remove file. * linux-aarch64-tdesc.h (initialize_low_tdesc): Remove. * linux-x86-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-x86-tdesc-selftest.c: Remove file. * linux-x86-tdesc.h (initialize_low_tdesc): Remove. gdb/testsuite/ChangeLog: * gdb.server/unittest.exp: Allow 0 unit tests to run. |

gdb/aarch64: Use type_align instead of aarch64_type_align
Replaces use of aarch64_type_align with common type_align function. Doing this fixes a bug in aarch64_type_align where static fields are considered as part of the alignment calculation of a struct, which results in arguments passed on the stack being misaligned. This bug is exposed in the new test gdb.cp/many-args.exp. Part of the old aarch64_type_align is retained and used as the gdbarch type align callback in order to correctly align vectors. gdb/ChangeLog: * aarch64-tdep.c (aarch64_type_align): Only handle vector override case. (pass_on_stack): Use type_align. (aarch64_gdbarch_init): Register aarch64_type_align gdbarch function. gdb/testsuite/ChangeLog: * gdb.cp/many-args.cc: New file. * gdb.cp/many-args.exp: New file. |

AArch64: View the pseudo V registers as vectors
When SVE is enabled, the V registers become pseudo registers based on the Z registers. They should look the same as they do when there is no SVE. The existing code viewed them as single value registers. Switch this to a vector. gdb/ChangeLog: * aarch64-tdep.c (aarch64_vnv_type): Use vector types. |

AArch64: Prologue scan unwinder support for signed return addresses
Pauth address signing is enabled at binary compile time. When enabled the return addresses for functions may be mangled. This patch adds functionality to restore the original address for use in the prologue scan unwinder. In the prologue analyzer, check for PACIASP/PACIBSP (enable address mangling) and AUTIASP/AUTIBSP (disable address mangling). When unwinding the PC from the prologue, unmask the register if required. Add a test case to the prologue tests. gdb/ChangeLog: * aarch64-tdep.c (aarch64_analyze_prologue): Check for pauth instructions. (aarch64_analyze_prologue_test): Add PACIASP test. (aarch64_prologue_prev_register): Unmask PC value. |

AArch64: DWARF unwinder support for signed return addresses
Pauth address signing is enabled at binary compile time. When enabled the return addresses for functions may be mangled. This patch adds functionality to restore the original address for use in the DWARF unwinder. DW_CFA_AARCH64_negate_ra_state in a binary indicates the toggling of address signing between enabled and disabled. Ensure the state is stored in the DWARF register ra_state. Ensure the pauth DWARF registers are initialised. gdb/ChangeLog: * aarch64-tdep.c (aarch64_frame_unmask_address): New function. (aarch64_dwarf2_prev_register): Unmask PC value. (aarch64_dwarf2_frame_init_reg): Init pauth registers. (aarch64_execute_dwarf_cfa_vendor_op): Check for DW_CFA_AARCH64_negate_ra_state. (aarch64_gdbarch_init): Add aarch64_execute_dwarf_cfa_vendor_op. |

AArch64: Add pauth DWARF registers
Map the pauth registers to DWARF. Add a new pseudo register ra_state and also map this to DWARF. This register is hidden from the user - prevent it from being read or written to. It will be used for the unmangling of addresses. gdb/ChangeLog: * aarch64-tdep.c (aarch64_dwarf_reg_to_regnum): Check for pauth registers. (aarch64_pseudo_register_name): Likewise.

AArch64: Add pointer authentication feature
Pointer Authentication is a new feature in AArch64 v8.3-a. When enabled in the compiler, function return addresses will be mangled by the kernel. Add register description xml and wire up to aarch64_linux_read_description. This description includes the two pauth user registers. Nothing yet uses the feature - that is added in later patches. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Add pauth param. * aarch64-linux-tdep.c (aarch64_linux_core_read_description): Likewise. * aarch64-tdep.c (struct target_desc): Add in pauth.

gdb/aarch64: Use default gdbarch methods where possible
Make use of the default gdbarch methods for gdbarch_dummy_id, gdbarch_unwind_pc, and gdbarch_unwind_sp where possible. I have not tested this change but, by inspecting the code, I believe the default methods are equivalent to the code being deleted. gdb/ChangeLog: * gdb/aarch64-tdep.c (aarch64_dummy_id): Delete. (aarch64_unwind_pc): Delete. (aarch64_unwind_sp): Delete. (aarch64_gdbarch_init): Don't register deleted functions with gdbarch. |

AArch64: Add default reggroups
AArch64 does not define any reggroups. This causes "maintenance print reggroups" to dump the default set (which is ok). However, if a new group is added via an xml file, then this now becomes the only group. Fixes gdb.xml/tdesc-regs.exp on AArch64. gdb/ChangeLog: * aarch64-tdep.c (aarch64_add_reggroups): New function (aarch64_gdbarch_init): Call aarch64_add_reggroups. |

AArch64 AAPCS: Ignore static members
Static members in C++ structs are global data and therefore not part of the list of struct members considered for passing in registers. Note the corresponding code in GCC (from which the GDB AAPCS code is based) does not have any static member checks due to the static members not being part of the struct type at that point. Extend gdb.base/infcall-nested-structs.exp to test structs with static members when compiled for C++. XFAIL more cases for x86_64 (see gdb/24104). For completeness, ensure some test cases have both empty structures and static members. Also fixes gdb.dwarf2/dw2-cp-infcall-ref-static.exp. gdb/ChangeLog: * aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1): Check for static members.

AArch64 AAPCS: Empty structs have non zero size in C++
When gdb.base/infcall-nested-structs.c is complied as C++, the compiler will not pass structs containing empty structs via float arguments. This is because structs in C++ have a minimum size of 1, causing padding in the struct once compiled. The AAPCS does not allow structs with padding to be passed in float arguments. Add padding checks to AArch64 and add C++ compile variant to the test. Some of the tests fail on X86_64. This has been raised as bug gdb/24104. gdb/ChangeLog: * aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1): Check for padding. gdb/testsuite/ChangeLog: * gdb.base/infcall-nested-structs.exp: Test C++ in addition to C. |

Update copyright year range in all GDB files.
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. |

Aarch64: Fix segfault when casting dummy calls
The following will segfault on aarch64 if foo is in another object, was compiled as c++ and has no debug symbols: (gdb) p (int)foo() This is because aarch64_push_dummy_call determines the return type of the function and then does not check for null pointer. A null pointer for the return type means the call has no debug information. For the code to get here, then the call must have been cast, otherwise we'd error out sooner. In the case of a no-debug-info call cast, the return type is the type the user had cast the call to, but we do not have that information available here. However, aarch64_push_dummy_call only requires the return type in order to calculate lang_struct_return. This information is available in the return_method enum. The fix is to simply use this instead. Adds testcase to check calls across objects, with all combinations of c, c++, debug and no debug. gdb/ChangeLog: PR gdb/22736: * aarch64-tdep.c (aarch64_push_dummy_call): Remove lang_struct_return code. gdb/testsuite/ChangeLog: PR gdb/22736: * gdb.cp/infcall-nodebug-lib.c: New test. * gdb.cp/infcall-nodebug-main.c: New test. * gdb.cp/infcall-nodebug.exp: New file. |

(AArch64) wrong value returned by "finish" for HFA
Consider the gdb.ada/array_return.exp testcase, and in particular, consider the following code... type Small_Float_Vector is array (1 .. 2) of Float; function Create_Small_Float_Vector return Small_Float_Vector is begin return (others => 4.25); end Create_Small_Float_Vector; ... which declares a type which is an array with 2 floats in it (floats are 4 bytes on AArch64), trying to get GDB to print the return value from that function does not work: (gdb) fin Run till exit from #0 pck.create_small_float_vector () at /[...]/pck.adb:15 0x000000000000062c in p () at /[...]/p.adb:11 11 Vector := Create_Small_Float_Vector; Value returned is $1 = (4.25, 0.0) ^^^ ||| We expected the value shown to be: (gdb) fin Run till exit from #0 pck.create_small_float_vector () at /[...]/pck.adb:15 0x000000000000062c in p () at /[...]/p.adb:11 11 Vector := Create_Small_Float_Vector; Value returned is $1 = (4.25, 4.25) Because the return type is an HFA, it is returned via the first two SIMD registers. However, what happens is that the current implementation fails to realize that this is an HFA, and therefore fetches the return value from the wrong location. And the reason why it fails to realize this is because it thinks that our array has 8 elements (HFAs have a maximum of 4). Looking at aapcs_is_vfp_call_or_return_candidate_1, where this is determined, we can easily see why (looks like a thinko): | case TYPE_CODE_ARRAY: | [...] | struct type *target_type = TYPE_TARGET_TYPE (type); | int count = aapcs_is_vfp_call_or_return_candidate_1 | (target_type, fundamental_type); | | if (count == -1) | return count; | !! -> | count *= TYPE_LENGTH (type); | return count; Here, we first determine the count for one element of our array, and so we should then be multiplying that count by the number of elements in our array (2 in our case). But instead, we multiply it by the total size (8). As a result, we do not classify the return type as an HFA, and thus pick the wrong location for fetching the return value. gdb/ChangeLog: * aarch64-tdep.c (aapcs_is_vfp_call_or_return_candidate_1): return the correct count for potential HFAs. Tested on aarch64-linux, fixes: array_return.exp: value printed by finish of Create_Small_Float_Vector |

Rename tdesc_register_size to tdesc_register_bitsize
tdesc_register_size returns number of bits, not bytes. Rename to make it clearer. Also, fixed bug in aarch64_get_tdesc_vq which assumed bytes. gdb/ * target-descriptions.c (tdesc_register_bitsize): Rename. * target-descriptions.h (tdesc_register_bitsize): Likewise. * rs6000-tdep.c (rs6000_gdbarch_init): Use new name. * aarch64-tdep.c (aarch64_get_tdesc_vq): Convert size. |
