gdb/ChangeLog: Update copyright year range in all GDB files
2018-01-02gdb/copyright.py: Remove testsuite/gdb.base/step-line.{c,inp} special handlingJoel Brobecker2-3/+6
In the past, these files needed to be handled by hand, because the testcase was sensitive to the length of the header, which was potentially changing when new copyright years were added to the copyright header. Now that we simply maintain and update a range, the length of the copyright header should not change as a consequence of the update performed by this script, so special handling of those files is no longer necessary. gdb/ChangeLog: * copyright.py (BY_HAND): Remove gdb/testsuite/gdb.base/step-line.inp and gdb/testsuite/gdb.base/step-line.c.
2018-01-02gdb/copyright.py: Do not forget to remind about MULTIPLE_COPYRIGHT_HEADERSJoel Brobecker2-1/+16
There is a small logical error in the part of the script that dumps the list of files in BY_HAND + MULTIPLE_COPYRIGHT_HEADERS but only checkis the contents of BY_HAND. The issue becomes apparent as soon as BY_HAND is empty. Prevent this from happening by treating the two lists separately, as this allows us to provide a more informative message in the case of MULTIPLE_COPYRIGHT_HEADERS. gdb/ChangeLog: * copyright.py (main): Dump the contents of MULTIPLE_COPYRIGHT_HEADERS (separately) from BY_HAND, even if BY_HAND is empty.

2017-12-31Avoid indexing std::vector past the endRuslan Kabatsayev2-4/+9
The code here wants to find address of an element, and often this element is one past the end of std::vector. Dereferencing that element leads to undefined behavior, so it's better to simply use pointer arithmetic instead of taking address of invalid dereference. gdb/ChangeLog: * psymtab.c (recursively_search_psymtabs): Use pointer arithmetic instead of dereferencing std::vector past the end.
2017-12-30Only ignore -Wenum-compare-switch if it existsSimon Marchi2-3/+12
My patch dwarf2read: Silence -Wenum-compare-switch warning 132448f8359a268f34f074b0908b5255b568da06 made some parts of dwarf2read.c ignore warnings about switch using enums of different kinds. What I did not realize was that older Clang versions (prior to 6) did not have that warning, and therefore give this error: /home/emaisin/src/binutils-gdb/gdb/dwarf2read.c:24187:7: error: unknown warning group '-Wenum-compare-switch', ignored [-Werror,-Wunknown-pragmas] DIAGNOSTIC_IGNORE_SWITCH_DIFFERENT_ENUM_TYPES ^ /home/emaisin/src/binutils-gdb/gdb/common/diagnostics.h:42:3: note: expanded from macro 'DIAGNOSTIC_IGNORE_SWITCH_DIFFERENT_ENUM_TYPES' DIAGNOSTIC_IGNORE ("-Wenum-compare-switch") ^ /home/emaisin/src/binutils-gdb/gdb/common/diagnostics.h:27:3: note: expanded from macro 'DIAGNOSTIC_IGNORE' _Pragma (STRINGIFY (GCC diagnostic ignored option)) ^ <scratch space>:10:25: note: expanded from here GCC diagnostic ignored "-Wenum-compare-switch" ^ Clang has a way to test if it knows about a particular warning. This patch uses that feature to only define DIAGNOSTIC_IGNORE_SWITCH_DIFFERENT_ENUM_TYPES to something if the warning is recognized by the Clang version being used. I tested building dwarf2read.c with clang 4, 5, 6, as well as gcc. gdb/ChangeLog: * common/diagnostics.h (DIAGNOSTIC_IGNORE_SWITCH_DIFFERENT_ENUM_TYPES): Only define if the compiler knows about -Wenum-compare-switch.

2017-12-29Ignore warning about using different types of enums in switchSimon Marchi3-0/+16
When compiling with clang 6, I see a bunch of warnings like this: /home/emaisin/src/binutils-gdb/gdb/amd64-linux-tdep.c:1427:8: error: comparison of two values with different enumeration types in switch statement ('enum amd64_syscall' and 'amd 64_x32_syscall') [-Werror,-Wenum-compare-switch] case amd64_x32_sys_move_pages: ^~~~~~~~~~~~~~~~~~~~~~~~ In this switch, we indeed use enumerators of both types amd64_x32_syscall and amd64_syscall. This is done on purpose, and the enum values are chosen so that they are complementary. I think it's still a useful warning, so I chose to ignore just that particular case. gdb/ChangeLog: * common/diagnostics.h (DIAGNOSTIC_IGNORE_SWITCH_DIFFERENT_ENUM_TYPES): New macro. * amd64-linux-tdep.c (amd64_canonicalize_syscall): Use it.
2017-12-29Remove unnecessary call to get_thread_db_infoSimon Marchi2-5/+6
In thread_db_detach, we call get_thread_db_info to first check if there exists a thread_db_info entry for the pid to detach. If there is, then we call delete_thread_db_info. It's unnecessary to call get_thread_db_info in the first place, since delete_thread_db_info handles the case where no thread_db_info entry exist for the given pid. gdb/ChangeLog: * linux-thread-db.c (thread_db_detach): Remove call to delete_thread_db_info.

2017-12-27reggroups: Add reggroup_gdbarch_new, reggroup_find for dynamic reggroupsStafford Horne3-0/+44
Traditionally reggroups have been created via reggroup_new() during initialization code and never freed. Now, if we want to initialize reggroups dynamically (i.e. in target description) we should be able to free them. Create this function reggroup_gdbarch_new() which will allocate the reggroup memory onto the passed gdbarch obstack. Also creating reggroup_find() as a utility to find a gdbarch registered reggroup object by name. gdb/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * reggroups.c (reggroup_gdbarch_new): New function. (reggroup_find): New function. * reggroups.h (reggroup_gdbarch_new): New function. (reggroup_find): New function.
2017-12-27reggroups: Convert reggroups from post_init to pre_initStafford Horne2-11/+13
Currently the reggroups gdbarch_data cannot be manipulated until after the gdbarch is completely initialized. This is usually done when the object init depends on architecture specific fields. In the case of reggroups it only depends on the obstack being available. Coverting this to pre_init allows using reggroups during gdbarch initialization. This is needed to allow registering arbitrary reggroups during gdbarch initializations. gdb/ChangeLog: yyyy-mm-dd Stafford Horne <shorne@gmail.com> * reggroups.c (reggroups_init): Change to depend only on obstack rather than gdbarch. (reggroup_add): Remove logic for forcing premature init. (_initialize_reggroup): Set `reggroups_data` with gdbarch_data_register_pre_init() rather than gdbarch_data_register_post_init().

2017-12-21Do not emit "field_type" var if not needed on "maint print c-tdesc"Simon Marchi37-51/+86
While fiddling a bit with -Wunused-variable, Sergio noticed that "maint print c-tdesc" was always generating code for the "tdesc_type *field_type" variable, even when it wasn't used. This is caught by GCC when using -Wunused-variable, of course. This patch changes the print_c_tdesc class to only output the field declaration when we actually need it. It shouldn't be necessary to do the same with the other variable declarations (type_with_fields and element_type), because they are always if they are declared. The C files in features/ are regenerated, some declarations of field_type are removed, as expected, while some others move to where they are used for the first time. gdb/ChangeLog: * target-descriptions.c (print_c_tdesc) <visit>: Don't output field_type declaration, use printf_field_type_assignment instead. <printf_field_type_assignment>: New method. * features/aarch64-core.c, features/aarch64-fpu.c features/arc-arcompact.c, features/arc-v2.c, features/arm/arm-with-iwmmxt.c, features/i386/32bit-core.c, features/i386/32bit-mpx.c, features/i386/32bit-sse.c, features/i386/64bit-avx512.c, features/i386/64bit-core.c, features/i386/64bit-mpx.c, features/i386/64bit-sse.c, features/i386/x32-core.c, features/or1k.c, features/rs6000/powerpc-7400.c, features/rs6000/powerpc-altivec32.c, features/rs6000/powerpc-altivec32l.c, features/rs6000/powerpc-altivec64.c, features/rs6000/powerpc-altivec64l.c, features/rs6000/powerpc-cell32l.c, features/rs6000/powerpc-cell64l.c, features/rs6000/powerpc-isa205-altivec32l.c, features/rs6000/powerpc-isa205-altivec64l.c, features/rs6000/powerpc-isa205-vsx32l.c, features/rs6000/powerpc-isa205-vsx64l.c, features/rs6000/powerpc-vsx32.c, features/rs6000/powerpc-vsx32l.c, features/rs6000/powerpc-vsx64.c, features/rs6000/powerpc-vsx64l.c, features/s390-gs-linux64.c, features/s390-tevx-linux64.c, features/s390-vx-linux64.c, features/s390x-gs-linux64.c, features/s390x-tevx-linux64.c, features/s390x-vx-linux64.c: Re-generate.

2017-12-20[Cell/B.E.] Fix regression due to gdbarch_significant_addr_bitUlrich Weigand3-0/+13
On Cell/B.E. multi-architecture debugging we use a "merged" address space that encodes both the main PowerPC address space and the local store address spaces of all active SPUs. This will always occupy 64 bits. However, gdbarch_addr_bit is set to 32 on SPU, and may be set to 32 as well on PowerPC. Since the new gdbarch_significant_addr_bit defaults to the value of gdbarch_addr_bit, this means addresses may be improperly truncated. Work around this problem by explicitly setting gdbarch_significant_addr_bit to 64 both for the SPU target and also for PowerPC target that support Cell/B.E. execution. gdb/ChangeLog: 2017-12-20 Ulrich Weigand <uweigand@de.ibm.com> * spu-tdep.c (spu_gdbarch_init): Set set_gdbarch_significant_addr_bit to 64 bits.

2017-12-19Correct disassembly of dot product instructions.Tamar Christina10-438/+471
Dot products deviate from the normal disassembly rules for lane indexed instruction. Their canonical representation is in the form of: v0.2s, v0.8b, v0.4b[0] instead of v0.2s, v0.8b, v0.b[0] to try to denote that these instructions select 4x 1 byte elements instead of a single 1 byte element.

2017-12-19Add support for V_4B so we can properly reject it.Tamar Christina9-3/+47
Previously parse_vector_type_for_operand was changed to allow the use of 4b register size for indexed lane instructions. However this had the unintended side effect of also allowing 4b for normal vector registers. Because this support was only partial the rest of the tool silently treated 4b as 8b and continued. This patch adds full support for 4b so it can be properly distinguished from 8b and the correct errors are generated. With this patch you still can't encode any instruction which actually requires v<num>.4b but such instructions don't exist so to prevent needing a workaround in get_vreg_qualifier_from_value this was just omitted. gas/ PR gas/22529 * config/tc-aarch64.c (vectype_to_qualifier): Support AARCH64_OPND_QLF_V_4B. * gas/testsuite/gas/aarch64/pr22529.s: New. * gas/testsuite/gas/aarch64/pr22529.d: New. * gas/testsuite/gas/aarch64/pr22529.l: New. include/ PR gas/22529 * opcode/aarch64.h (aarch64_opnd_qualifier): Add AARCH64_OPND_QLF_V_4B. opcodes/ PR gas/22529 * aarch64-opc.c (aarch64_opnd_qualifiers): Add 4b variant.

2017-12-19PR22626, invalid dynindx used for dynamic relocs against section symsAlan Modra2-8/+22
_bfd_elf_link_renumber_dynsyms is called twice by the linker. The first call in bfd_elf_size_dynamic_sections is just to answer the question as to whether there are there any dynamic symbols. The second call in bfd_elf_size_dynsym_hash_dynstr sets the st_shndx value that dynamic symbols will have. strip_excluded_output_sections is called between these two calls. So sections seen on the first _bfd_elf_link_renumber_dynsyms pass might differ from those seen on the second pass. Unfortunately, that can result in a stripped section's dynamic symbol being assigned a dynindx on the first pass but not corrected to the final value (of zero, ie. not dynamic) on the second pass. PowerPC, x86, mips, and most other targets that emit dynamic section symbols, just test that section symbol dynindx is non-zero before using a given section symbol in dynamic relocations. This patch prevents _bfd_elf_link_renumber_dynsyms from setting any section symbol dynindx on the first pass. PR 22626 * elflink.c (_bfd_elf_link_renumber_dynsyms): Don't set section dynindx when section_sym_count is NULL.

2017-12-18x86: fold certain AVX and AVX2 templatesJan Beulich7-4144/+841
Just like for instructions in GPRs, there's no need to have separate templates for otherwise identical insns acting on XMM or YMM registers (or memory of the same size).
2017-12-18x86: fold RegXMM/RegYMM/RegZMM into RegSIMDJan Beulich11-46431/+46461
... qualified by their respective sizes, allowing to drop FirstXmm0 at the same time.
2017-12-18x86: drop FloatReg and FloatAccJan Beulich8-32592/+32603
Express them as Reg|Tbyte and Acc|Tbyte respectively.
2017-12-18x86: replace Reg8, Reg16, Reg32, and Reg64Jan Beulich10-32899/+33388
Use a combination of a single new Reg bit and Byte, Word, Dword, or Qword instead. Besides shrinking the number of operand type bits this has the benefit of making register handling more similar to accumulator handling (a generic flag is being accompanied by a "size qualifier"). It requires, however, to split a few insn templates, as it is no longer correct to have combinations like Reg32|Reg64|Byte. This slight growth in size will hopefully be outweighed by this change paving the road for folding a presumably much larger number of templates later on.
