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.

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.

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.

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.

2017-03-24Avoid segfault on invalid directory tablePádraig Brady2-6/+22
gdb was segfaulting during backtrace on a binary here, where fe->dir_index parsed from the DWARF info was seen to access beyond the provided include_dirs array. This commit bounds the access to entries actually written to the array, and was verified to output the backtrace correctly. gdb/ChangeLog: * dwarf2read.c (setup_type_unit_groups): Ensure dir_index doesn't reference beyond the 'lh->include_dirs' array before accessing to it. (psymtab_include_file_name): Likewise. (dwarf_decode_lines_1): Likewise. (dwarf_decode_lines): Likewise. (file_file_name): Likewise.
2017-03-24[GAS/ARM] Fix selected_cpu with default CPU and -mcpuThomas Preud'homme2-2/+7
When GAS is compiled with DEFAULT_CPU set and then run with a -mcpu or -march option, selected_cpu will be set to the default CPU. This means the -mcpu is ignored which is surprising behavior. This commit instead sets selected_cpu from the value passed to -mcpu/-march. 2017-03-24 Thomas preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.: (md_begin): Set selected_cpu from *mcpu_cpu_opt when CPU_DEFAULT is defined.

2017-03-23Remove some unnecessary inferior_ptid setting/restoring when ↵Simon Marchi6-82/+39
fetching/storing registers Now that the to_fetch_registers, to_store_registers and to_prepare_to_store target methods don't rely on the value of inferior_ptid anymore, we can remove a bunch of now unnecessary setting and restoring of inferior_ptid. The asserts added recently in target_fetch_registers and target_store_registers, which validate that inferior_ptid matches the regcache's ptid, must go away. It's the whole point of this effort, to not require inferior_ptid to have a particular value when calling these functions. One thing that I noticed is how sol-thread.c's ps_lgetregs and friends use the current value of inferior_ptid instead of what's passed as argument (ph->ptid), unlike proc-service.c's versions of the same functions. Is it expected? I left it like this in the current patch, but unless there's a good reason for it to be that way, I guess we should make it use the parameter. gdb/ChangeLog: * fbsd-tdep.c (fbsd_corefile_thread): Don't set/restore inferior_ptid. * proc-service.c (ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs): Likewise. * regcache.c (regcache_raw_update, regcache_raw_write): Likewise. * sol-thread.c (ps_lgetregs, ps_lsetregs, ps_lgetfpregs, ps_lsetfpregs): Likewise. * target.c (target_fetch_registers, target_store_registers): Remove asserts.

2017-03-23Remove constness of libdir in do_start_initializationAndreas Arnez1-1/+1
The patch "Fix memory leak in python.c:do_start_initialization" (https://sourceware.org/ml/gdb-patches/2017-03/msg00407.html) introduced a compilation error on some platforms: ../../binutils-gdb/gdb/python/python.c: In function bool do_start_initialization(): ../../binutils-gdb/gdb/python/python.c:1556:16: error: invalid conversion from const void* to void* [-fpermissive] xfree (libdir); ^ This is fixed by removing the constness of libdir's data type. gdb/ChangeLog: * python/python.c (do_start_initialization): Remove 'const' from data type of libdir.
2017-03-23Fix memory leak in python.c:do_start_initializationPhilipp Rudo2-1/+7
When intializing Python the path to the python binary is build the following way progname = concat (ldirname (python_libdir), SLASH_STRING, "bin", SLASH_STRING, "python", (char *) NULL); This is problematic as both concat and ldirname allocate memory for the string they return. Thus the memory allocated by ldirname cannot be accessed afterwards causing a memory leak. Fix it by temporarily storing libdir in a variable and xfree it after concat. gdb/ChangeLog: python/python.c (do_start_initialization): Fix memory leak.

2017-03-22Sanitize RISC-V GAS help text, documentationPalmer Dabbelt3-7/+17
It looks like I missed the GAS help text when going through all the documentation last time, so it printed some of the old-format (never upstream) arguments. I fixed this, and when I went to check doc/ I noticed it was missing the '-fpic'/'-fno-pic' options.
