2016-09-02Handle DW_OP_form_tls_addressTom Tromey6-7/+26
Currently gdb supports DW_OP_GNU_push_tls_address, but not DW_OP_form_tls_address. I think it would be better if the toolchain as a whole moved to using the standard opcode, and the prerequisite to this is getting gdb to recognize it. GCC can sometimes emit DW_OP_form_tls_address for emultls targets. As far as I know, nobody has ever tried this with gdb (since it wouldn't work at all). I don't think there's a major drawback to using a single opcode for all targets, because computing the location of a thread-local is already target specific. This is PR gdb/11616. I don't know how to write a test case for this; though it's worth noting that there aren't explicit tests for DW_OP_GNU_push_tls_address either -- and if I change GCC, these paths will be tested to the same extent they are now. 2016-09-02 Tom Tromey <tom@tromey.com> PR gdb/11616: * dwarf2read.c (decode_locdesc): Handle DW_OP_form_tls_address. * dwarf2loc.c (dwarf2_compile_expr_to_ax): Handle DW_OP_form_tls_address.

2016-09-02[GDBserver] Replace "reinsert_breakpoint" with "single_step_breakpoint"Yao Qi3-89/+90
reinsert_breakpoint is used for software single step, so it is more clear to rename it to single_step_breakpoint. This was pointed out in the review https://sourceware.org/ml/gdb-patches/2016-05/msg00429.html I don't rename "other_breakpoint" in this patch. gdb/gdbserver: 2016-09-02 Yao Qi <yao.qi@linaro.org> * linux-low.c: Replace "reinsert_breakpoints" with "single_step_breakpoints".

2016-09-02Detect broken ptrace in gdb_skip_float_testYao Qi12-28/+156
We recently found a ARM kernel ptrace bug http://lists.infradead.org/pipermail/linux-arm-kernel/2016-May/431962.html Details can be found in the comment in gdb_skip_float_test. We can skip floating point tests if the kernel bug is detected. This patch adds more code in gdb_skip_float_test to detect the broken ptrace on arm-linux. Such detection should be done at the beginning of the test, because it starts a fresh GDB, so change the test cases to invoke gdb_skip_float_test at the beginning of test, and use its return value afterwards. Since gdb_skip_float_test becomes a gdb_caching_proc, so it can't have an argument, this patch also removes argument "msg", which isn't useful. gdb/testsuite: 2016-09-02 Yao Qi <yao.qi@linaro.org> * gdb.arch/arm-neon.exp: Skip it if gdb_skip_float_test returns true. * gdb.base/call-ar-st.exp: Invoke gdb_skip_float_test. * gdb.base/call-rt-st.exp: Likewise. * gdb.base/call-sc.exp: Invoke gdb_skip_float_test and use its return value instead of gdb,skip_float_test. * gdb.base/callfuncs.exp: Invoke gdb_skip_float_test.

2016-09-01Share target_wait prototype between GDB and gdbserverSergio Durigan Junior6-12/+37
This commit moves the target_wait prototype from the GDB-specific target.h header to the common target/target.h header. Then, it creates a compatible implementation of target_wait on gdbserver using the_target->wait, and adjusts the (only) caller (mywait function). Pretty straightforward, no regressions introduced. gdb/gdbserver/ChangeLog: 2016-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * target.c (mywait): Call target_wait instead of the_target->wait. (target_wait): New function. gdb/ChangeLog: 2016-09-01 Sergio Durigan Junior <sergiodj@redhat.com> * target.c (target_wait): Mention that the function's prototype can be found at target/target.h. * target.h (target_wait): Move prototype from here... * target/target.h (target_wait): ... to here.
2016-09-01Use target_continue{,_no_signal} instead of target_resumeSergio Durigan Junior9-31/+60
This commit implements a new function, target_continue, on top of the target_resume function. Then, it replaces all calls to target_resume by calls to target_continue or to the already existing target_continue_no_signal. This is one of the (many) necessary steps needed to consolidate the target interface between GDB and gdbserver. In particular, I am interested in the impact this change will have on the unification of the fork_inferior function (which I have been working on). Tested on the BuildBot, no regressions introduced. gdb/gdbserver/ChangeLog: 2016-09-31 Sergio Durigan Junior <sergiodj@redhat.com> * server.c (start_inferior): New variable 'ptid'.

2016-08-31Fix lwp_suspend/unsuspend imbalance in linux_wait_1Antoine Tremblay2-18/+23
This patch fixes imbalanced lwp_suspend/unsuspend calls caused by the premature choosing of another event for fairness. select_event_lwp would switch the event before a call to unsuspend_all_lwps, thus it would be called with the wrong event. This caused an assertion failure: unsuspend LWP xx, suspended=-1 when testing gdb.threads/non-stop-fair-events.exp with ARM range stepping in GDBServer. This patch moves the switch of event after the unsuspend/unstop calls. No regressions, tested on ubuntu 14.04 ARMv7 and x86.

2016-08-26 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * bfd-in.h (bfd_elf32_arm_set_target_relocs): Add a new parameter for the input import library bfd. * bfd-in2.h: Regenerate. * elf32-arm.c (struct elf32_arm_link_hash_table): New in_implib_bfd and new_cmse_stub_offset fields. (stub_hash_newfunc): Initialize stub_offset and stub_template_size to -1. (elf32_arm_add_stub): Likewise for stub_offset. (arm_new_stubs_start_offset_ptr): New function. (arm_build_one_stub): Only allocate a stub_offset if it is -1. Allow empty SG veneers to have zero relocations. (arm_size_one_stub): Only initialize stub size and template information for non empty veneers. Do not update veneer section size if veneer already has an offset. (elf32_arm_create_stub): Return the stub entry pointer or NULL instead of a boolean indicating success or failure. (cmse_scan): Change stub_changed parameter into an integer pointer parameter cmse_stub_created to count the number of stub created and adapt to change of return value in elf32_arm_create_stub. (cmse_entry_fct_p): New function. (arm_list_new_cmse_stub): Likewise. (set_cmse_veneer_addr_from_implib): Likewise. (elf32_arm_size_stubs): Define cmse_stub_created, pass its address to cmse_scan instead of that of cmse_stub_changed to compute the number of stub created and use it to initialize stub_changed. Call set_cmse_veneer_addr_from_implib after all cmse_scan. Adapt to change of return value in elf32_arm_create_stub. Use arm_stub_section_start_offset () if not NULL to initialize size of secure gateway veneers section. Initialize stub_offset of Cortex-A8 erratum fix to -1. Use ret to hold return value. (elf32_arm_build_stubs): Use arm_stub_section_start_offset () if not NULL to initialize size of secure gateway veneers section. Adapt comment to stress the importance of zeroing veneer section content. (bfd_elf32_arm_set_target_relocs): Add new in_implib_bfd parameter to initialize eponymous field in struct elf32_arm_link_hash_table. ld/ * emultempl/armelf.em (in_implib_filename): Declare and initialize new variable. (arm_elf_create_output_section_statements): Open import input library file for writing and pass resulting in_implib_bfd to bfd_elf32_arm_set_target_relocs. (PARSE_AND_LIST_PROLOGUE): Define OPTION_IN_IMPLIB option. (PARSE_AND_LIST_LONGOPTS): Define --in-implib option. (PARSE_AND_LIST_OPTIONS): Add help message for --in-implib option. (PARSE_AND_LIST_ARGS_CASES): Handle new OPTION_IN_IMPLIB case. * ld.texinfo (--cmse-implib): Update to mention --in-implib. (--in-implib): Document new option. * NEWS: Likewise. * testsuite/ld-arm/arm-elf.exp (Secure gateway import library generation): add --defsym VER=1 to gas CLI. (Secure gateway import library generation: errors): Likewise. (Input secure gateway import library): New test. (Input secure gateway import library: no output import library): Likewise. (Input secure gateway import library: not an SG input import library): Likewise. (Input secure gateway import library: earlier stub section base): Likewise. (Input secure gateway import library: later stub section base): Likewise. (Input secure gateway import library: veneer comeback): Likewise. (Input secure gateway import library: entry function change): Likewise. * testsuite/ld-arm/cmse-implib.s: Add input import library testing. * testsuite/ld-arm/cmse-implib.rd: Update accordingly. * testsuite/ld-arm/cmse-new-implib.out: New file. * testsuite/ld-arm/cmse-new-implib.rd: Likewise. * testsuite/ld-arm/cmse-new-implib-no-output.out: Likewise. * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out: Likewise. * testsuite/ld-arm/cmse-new-earlier-later-implib.out: Likewise. * testsuite/ld-arm/cmse-new-comeback-implib.rd: Likewise. * testsuite/ld-arm/cmse-new-wrong-implib.out: Likewise.
