Use symbolic constants from include/coff/internal.h instead of magic numbers with add_data_entry() bfd/ChangeLog: 2017-04-02 Jon Turney <jon.turney@dronecode.org.uk> (_bfd_XXi_swap_aouthdr_out): For clarity, use defines rather than numbers for DataDirectory entry indicies passed to add_data_entry().
2017-04-04Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXXH.J. Lu40-31/+660
Mark an ALLOC section, which should be placed in special memory area, with SHF_GNU_MBIND. Its sh_info field indicates the special memory type. GNU_MBIND section names start with ".mbind" so that they are placed as orphan sections by linker. All input GNU_MBIND sections with the same sh_type, sh_flags and sh_info are placed in one output GNU_MBIND section. In executable and shared object, create a GNU_MBIND segment for each GNU_MBIND section and its segment type is PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is aligned at page boundary. The assembler syntax: .section .mbind.foo,"adx",%progbits ^ 0: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.foo,"adx",%progbits,0x1 ^ 1: Special memory type. | 'd' for SHF_GNU_MBIND. .section .mbind.bar,"adG",%progbits,.foo_group,comdat,0x2 ^ 2: Special memory type. | 'd' for SHF_GNU_MBIND. bfd/ * elf.c (get_program_header_size): Add a GNU_MBIND segment for each GNU_MBIND section and align GNU_MBIND section to page size.

2017-04-04gdbserver: Clear .deps on cleanSimon Marchi2-0/+5
In some situations, the dependency tracking files in .deps can refer to source files that were removed or renamed, leading to errors like: make: *** No rule to make target `version.c', needed by `version.o'. Stop. This patch makes the clean target clear the .deps directory, which gives the user a chance to recover from the error wihtout knowing about the internals of the build system. It is already done for GDB. See here for more details: https://sourceware.org/ml/gdb-patches/2009-03/msg00000.html gdb/gdbserver/ChangeLog: * Makefile.in (clean): Clear .deps.

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 prologue analysisAnton Kolesov7-22/+1603
Add a prologue analysis that recognizes all instructions that may happen in compiler-generated prologue, including various stores, core register moves, subtraction and ENTER_S instruction that does a lot of prologue actions through microcode. Testcases cover various prologue scenarios, including instructions that are spread across multiple 16-bit encodings (for example there are 7 encodings of store instruction). gdb/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * arc-tdep.c (arc_frame_cache): Add support for prologue analysis.

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.

2017-03-27gdb: xtensa: fix test for privileged register numberMax Filippov2-1/+8
There are no a0-a15 pseudoregisters at the top of the register set in call0 registers layout. All registers above gdbarch_num_regs (gdbarch) are privileged. Treat them as such. 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.

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.

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.
