2017-04-03ld: Support ELF GNU program propertiesH.J. Lu50-3/+1851
From .note.gnu.property section in each ELF input, we build a list of GNU properties if .note.gnu.property section isn't corrupt. The unknown properties are ignored. All property lists in relocatable inputs are merged into an output property list. When -z stack-size=N is used and N isn't 0, the GNU_PROPERTY_STACK_SIZE property will be merged with or added to the output property list. .note.gnu.property section is generated in output from the output property list. bfd/ * Makefile.am (BFD32_BACKENDS): Add elf-properties.lo.

2017-03-31gdbserver: Suffix generated C files with -generatedSimon Marchi3-65/+33
I noticed that there were some missing files in gdbserver's gitignore (some generated register format .c files). Of course the easy fix would be to add those files to .gitignore, but I think we can do a better job, so that we don't have to worry about adding generated files to .gitignore or the clean Makefile target. I suggest naming all generated source files -generated.c. This way, we can use a single rule in .gitignore and do a "rm -f *-generated.c" to clean them up. New in v2: - Don't rename version.o and xml-builtin.o gdb/gdbserver/ChangeLog: * .gitignore: Remove generated files, replace with wildcard. * (clean): Replace removal of generated files with wildcard.

2017-03-30Fix classification of `module.type' in D lexer.Iain Buclaw3-0/+120
The two-tier lexer in gdb/d-exp.y, which resolves fully qualified names missed a case where `module.type' was not being classified as one token. And so when the grammar takes over, it matched the remaining tokens against the rule `TypeExp . IdentifierExp', where we were expecting to instead match cast expression `( TypeExp ) UnaryExpression'. Adding a case for TYPE_CODE_MODULE in type_aggregate_p means that classify_inner_name will get a chance to lookup the symbol. This was noticed when using `watch -l', and got the rather confusing response: A syntax error in expression, near `) 0x0add4e55'. So it's been included in the testsuite, along with another test that does effectively the same expression, but explicitly. gdb/ChangeLog: * d-exp.y (type_aggregate_p): Treat TYPE_CODE_MODULE as being aggregate-like. gdb/testsuite/ChangeLog: * gdb.dlang/watch-loc.c: New file. * gdb.dlang/watch-loc.exp: New file.

2017-03-28arc: Add disassembler helperAnton Kolesov9-1/+1509
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.

This fixes the following gdb assertion seen when 'finish' command is invoked: regcache.c:649: internal-error: register_status regcache_raw_read(regcache*, int, gdb_byte*): Assertion `regnum >= 0 && regnum < regcache->descr->nr_raw_registers' failed. gdb/ 2017-03-27 Max Filippov <jcmvbkbc@gmail.com> * xtensa-tdep.c (xtensa_pseudo_register_read): Treat all registers above gdbarch_num_regs (gdbarch) as privileged in call0 ABI.
2017-03-27gdbserver: xtensa: add call0 supportMax Filippov2-0/+35
Correctly handle a0- registers on requests from remote gdb. This fixes 'Register 1 is not available' and subsequent assertion in the remote gdb connecting to the gdbserver: 'findvar.c:291: internal-error: value_of_register_lazy: Assertion `frame_id_p(get_frame_id (frame))' failed.' The register structure is the same for windowed and call0 ABIs because currently linux kernel internally requires windowed registers, so they are always present. gdb/gdbserver/ 2017-03-27 Max Filippov <jcmvbkbc@gmail.com> * linux-xtensa-low.c (xtensa_fill_gregset): Call collect_register for all registers in a0_regnum..a0_regnum + C0_NREGS range. (xtensa_store_gregset): Call supply_register for all registers in a0_regnum..a0_regnum + C0_NREGS range.
2017-03-27gdb: xtensa-linux: add call0 supportMax Filippov2-0/+37
Correctly handle a0- registers. This allows debugging call0 code in linux natively. The register structure is the same for windowed and call0 ABIs because currently linux kernel internally requires windowed registers, so they are always present. gdb/ 2017-03-27 Max Filippov <jcmvbkbc@gmail.com> * xtensa-linux-nat.c (fill_gregset): Call regcache_raw_collect for a single specified register or for all registers in a0_base..a0_base + C0_NREGS range. (supply_gregset_reg): Call regcache_raw_supply for a single specified register or for all registers in a0_base..a0_base + C0_NREGS range.

Both gdb and gdbserver need this definition to properly work with call0 ABI. Make it available to both. gdb/ 2017-03-27 Max Filippov <jcmvbkbc@gmail.com> * arch/xtensa.h (C0_NREGS): Add definition. * xtensa-tdep.c (C0_NREGS): Remove definition.
2017-03-27gdb: xtensa: clean up xtensa_default_isa initializationMax Filippov2-4/+9
This fixes segfault in native gdb because isa is not initialized at the point of call to xtensa_isa_maxlength. gdb/ 2017-03-27 Max Filippov <jcmvbkbc@gmail.com> * xtensa-tdep.c (xtensa_scan_prologue, call0_analyze_prologue): Drop xtensa_default_isa initialization.

2017-03-27dwarf2read.c: Clean up out of bounds handlingPedro Alves2-70/+106
Multiple places in dwarf2read.c open code 1-based to 0-based index conversion and check for out of bounds accesses to lh->include_dirs and lh->file_names. This commit factors those out to a couple methods and uses them throughout. gdb/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * dwarf2read.c (file_entry) <dir_index>: Add comment. (file_entry::include_dir): New method. (line_header::include_dir_at, line_header::file_name_at): New methods. (setup_type_unit_groups, setup_type_unit_groups) (psymtab_include_file_name): Simplify using the new methods. (lnp_state_machine) <the_line_header>: New field. <file>: Add comment. (lnp_state_machine::current_file): New method. (dwarf_record_line): Simplify using the new methods. (init_lnp_state_machine): Initialize the "the_line_header" field. (dwarf_decode_lines_1, dwarf_decode_lines, file_file_name): Simplify using the new methods.
2017-03-27gdb/cp-name-parser.y: Eliminate make_empty, use cplus_demangle_fill_componentPedro Alves2-46/+21
The demangler exports the cplus_demangle_fill_component function that clients should use to initialize demangle_component components that use the "s_binary" union member. cp-name-parser.y uses it in some places, via the fill_comp wrapper, but not all. Several places instead use a GDB-specific "make_empty" function. Because this function does not call any of the demangler "fill" functions, we had to patch it recently to clear the allocated demangle_component's "d_printing" field, which is supposedly a "private" demangler field. To avoid such problems in the future, this commit switches those places to use "fill_comp" instead, and eliminates the "make_empty" function. gdb/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * cp-name-parser.y (make_empty): Delete. (demangler_special, nested_name, ptr_operator, array_indicator) (direct_declarator, declarator_1): Use fill_comp instead of make_empty.
2017-03-27cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCEPedro Alves2-0/+6
This patch almost a decade ago: ... 2007-08-31 Douglas Gregor <doug.gregor@gmail.com> * cp-demangle.c (d_dump): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE. (d_make_comp): Ditto. ... ... missed doing the same change to cplus_demangle_fill_component that was done to d_make_comp. I.e., teach it to only validate that we're not passing in a "right" subtree. GDB has recently (finally) learned about rvalue references, and a change to make it use cplus_demangle_fill_component more ran into an assertion because of this. (GDB is the only user of cplus_demangle_fill_component in both the gcc and binutils-gdb trees.) libiberty/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * cp-demint.c (cplus_demangle_fill_component): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE.

2017-03-27Fix gdb_xml_debug/gdb_xml_error ATTRIBUTE_PRINTF usePedro Alves4-5/+14
The declarations of gdb_xml_debug and gdb_xml_error are passing "0" as "first-to-check" argument to ATTRIBUTE_PRINTF, as if they were va_args functions. Consequently, the arguments to gdb_xml_debug / gdb_xml_error aren't being checked against the format strings. With that fixed, a couple obvious bugs are exposed, both fixed by this commit. gdb/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * xml-support.h (gdb_xml_debug): Pass a "first-to-check" argument to ATTRIBUTE_PRINTF. * solib-target.c (library_list_start_list): Print "string" not "version". * xml-tdesc.c (tdesc_start_field): Pass "field_name" to gdb_xml_error call.
