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.

2017-10-11arc: Pass proper CPU value to the disassemblerAnton Kolesov1-0/+15
There was a problem with generation of the disassembler options for ARC in GDB, because a BFD architecture name was used as a CPU name, but they have different meaning even if some architectures have same name as respective CPUs. Target description specifies a BFD architecture, which is different from ARC CPU, as accepted by the disassembler (and most other ARC tools), because CPU values are much more fine grained - there can be multiple CPU values per single BFD architecture. As a result this code should translate architecture to some CPU value. Since there is no info on exact CPU configuration, it is best to use the most feature-rich CPU, so that the disassembler will recognize all instructions available to the specified architecture. gdb/ChangeLog yyyy-mm-dd Anton Kolesov <Anton.Kolesov@synopsys.com> * arc-tdep.c (arc_gdbarch_init): Pass proper cpu value to disassembler. * arc-tdep.h (arc_arch_is_em): New function. (arc_arch_is_hs): Likewise. gdb/testsuite/ChangeLog yyyy-mm-dd Anton Kolesov <Anton.Kolesov@synopsys.com> * gdb.arch/arc-tdesc-cpu.exp: New file. * gdb.arch/arc-tdesc-cpu.xml: Likewise.
2017-03-28arc: Add disassembler helperAnton Kolesov1-0/+25
Add disassembler helper for GDB, that uses opcodes structure arc_instruction and adds convenience functions to handle instruction operands. This interface solves at least those problems with arc_instruction: * Some instructions, like "push_s", have implicit operands which are not directly present in arc_instruction. * Operands of particular meaning, like branch/jump targets, have various locations and meaning depending on type of branch/target. * Access to operand value is abstracted into a separate function, so callee code shouldn't bother if operand value is an immediate value or in a register. Testcases included in this commit are fairly limited - they test exclusively branch instructions, something that will be used in software single stepping. Most of the other parts of this disassembler helper are tested during prologue analysis testing. gdb/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * configure.tgt: Add arc-insn.o. * arc-tdep.c (arc_delayed_print_insn): Make non-static. (dump_arc_instruction_command): New function. (arc_fprintf_disasm): Likewise. (arc_disassemble_info): Likewise. (arc_insn_get_operand_value): Likewise. (arc_insn_get_operand_value_signed): Likewise. (arc_insn_get_memory_base_reg): Likewise. (arc_insn_get_memory_offset): Likewise. (arc_insn_get_branch_target): Likewise. (arc_insn_dump): Likewise.

2017-03-28arc: Align internal regnums with architectural regnumsAnton Kolesov1-0/+16
Add ARC_LIMM_REGNUM to arc_regnum enumeration and assign a number 62 to it. This ensures that for core registers internal register numbers in this enum are the same as architectural numbers. This allows to use internal register numbers in the contexts where architectural number is implied, for example when disassembling instruction during prologue analysis. gdb/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * arc-tdep.c (core_v2_register_names, core_arcompact_register_names) Add "limm" and "reserved". (arc_cannot_fetch_register, arc_cannot_store_register): Add ARC_RESERVED_REGNUM and ARC_LIMM_REGNUM. * arc-tdep.h (arc_regnum): Likewise.
2017-01-01update copyright year range in GDB filesJoel Brobecker1-1/+1
This applies the second part of GDB's End of Year Procedure, which updates the copyright year range in all of GDB's files. gdb/ChangeLog: Update copyright year range in all GDB files.
2016-10-12arc: Add evaluation of long jump targetsAnton Kolesov1-0/+3
Standard get_longjmp_target implementation, similar to what is in arm-tdep.c. Actual value of jb_pc should be set in init_osabi methods of particular OS/ABI implementations. gdb/ChangeLog: * arc-tdep.h (struct gdbarch_tdep) <jb_pc>: New field. * arc-tdep.c (arc_get_longjmp_target): New function. (arc_gdbarch_init): Set get_longjmp_target if jb_pc is non-negative. (arc_dump_tdep): Print jb_pc.
2016-10-12arc: Add a gdbarch_tdep structureAnton Kolesov1-0/+6
Add target-specific structure gdbarch_tdep for ARC. gdb/ChangeLog: * arc-tdep.h (struct gdbarch_tdep): New. * arc-tdep.c (arc_gdbarch_init): Allocate gdbarch_tdep.
2016-09-21arc: New Synopsys ARC portAnton Kolesov1-0/+101
ARC is a family of licensable processors developed by Synopsys. This is an initial patch that doesn't yet support some of the features, that are already available in Synopsys' fork of GDB, namely: * longjmp support * signal frame handling * prologue analysis * Linux targets support * native Linux support ARC cores are configurable and extensible, which means from debugger perspective that some registers and debug capabilities are optional, therefore it is up to the GDB stub to determine exact list of register available on target and supply it to GDB via XML target descriptions. List of registers that is known to GDB and is required is intentionally kept small to simplify requirements to GDB stub and implementation of a GDB client. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add arc-tdep.o. (HFILES_NO_SRCDIR): Add arc-tdep.h. (ALLDEPFILES): Add arc-tdep.c. * NEWS: Mention new ARC port. * configure.tgt: Add ARC. * arc-tdep.c: New file. * arc-tdep.h: New file. * features/Makefile (XMLTOC): Add arc-v2.xml and arc-arcompact.xml. * features/arc-v2.xml: New file. * features/arc-v2.c: New file (generated). * features/arc-arcompact.xml: New file. * features/arc-arcompact.c: New file (generated). gdb/doc/ChangeLog: * gdb.texinfo (Embedded Processors): Document ARC. (Synopsys ARC): New section. (Standard Target Features): Document ARC features. (ARC Features): New section. gdb/testsuite/ChangeLog: * gdb.xml/tdesc-regs.exp: set core-regs for arc*-*-elf32.
