2017-11-01[ARM] Fix Coprocessor instructions availabilityThomas Preud'homme26-35/+328
A few coprocessor instructions introduced in ARMv2 are currently accepted by GAS when targeting ARMv1 due to a typo in the code. This patch fixes the issue and introduce a more fine grained testing for coprocessor instructions availability. Coprocessor instructions are grouped as follows: * ARM coprocessor instructions introduced in ARMv2 Includes: ldc, stc, mcr, mrc, cdp, ldcl, stcl Guarded by: ARM_EXT_V2 Tests: copro-arm_v2plus-arm_v*.d * ARM coprocessor instructions introduced in ARMv5 Includes: ldc2, ldc2l, stc2, stc2l, cdp2, mcr2, mrc2 Guarded by: ARM_EXT_V5 Tests: copro-arm_v5plus-arm_v*.d * ARM coprocessor instructions introduced in ARMv5TE Includes: mcrr, mrrc Guarded by: ARM_EXT_V5E Tests: copro-arm_v5teplus-arm_v*.d * ARM coprocessor instructions introduced in ARMv6 Includes: mcrr2, mrrc2 Guarded by: ARM_EXT_V6 Tests: copro-arm_v6plus-arm_v*.d * Thumb coprocessor instructions introduced in ARMv6T2 Includes: ldc, ldcl, stc, stcl, mcr, mrc, mcrr, mrrc, cdp, ldc2, ldc2l, stc2, stc2l, cdp2, mcr2, mrc2, mcrr2, mrrc2 Guarded by: ARM_EXT_V6T2 Tests: copro-thumb_v6t2plus-thumb_v*.d For each of these groups, at least 2 tests are performed: * instructions are not available in earlier architecture * instructions are available in architecture where they were introduced More tests need to be performed when instructions in a group span several assembly files. Note that an instruction in the original coprocessor testcase is changed to unified syntax to allow the testcase to be assembled for ARM and Thumb state. Correct processing of legacy syntax is covered in other testcases. 2017-11-01 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (arm_ext_v2): Define to ARM_EXT_V2 feature bit. * testsuite/gas/arm/copro.s: Split into ... * testsuite/gas/arm/copro-arm_v2plus-thumb_v6t2plus.s: This while changing it to unified syntax and ... * testsuite/gas/arm/copro-arm_v5plus-thumb_v6t2plus.s: this and ... * testsuite/gas/arm/copro-arm_v5teplus-thumb_v6t2plus.s: This and ... * testsuite/gas/arm/copro-arm_v6plus-thumb_v6t2plus.s: This. * testsuite/gas/arm/copro.d: Split into ... * testsuite/gas/arm/copro-arm_v2plus-arm_v2.d: This but target ARMv2 and ... * testsuite/gas/arm/copro-arm_v5plus-arm_v5.d: this but target ARMv5 and ... * testsuite/gas/arm/copro-arm_v5teplus-arm_v5te.d: This but target ARMv5TE and ... * testsuite/gas/arm/copro-arm_v6plus-arm_v6.d: This but target ARMv6. * testsuite/gas/arm/copro-arm_v2plus-arm_v1.d: New testcase. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v4t-1.d: New testcase. * testsuite/gas/arm/copro-arm_v2plus-thumb_v6t2plus-unavail.l: Expected errors for the above two testcases. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v6t2-1.d: New testcase. * testsuite/gas/arm/copro-arm_v5plus-arm_v4.d: New testcase. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v4t-2.d: New testcase. * testsuite/gas/arm/copro-arm_v5plus-thumb_v6t2plus-unavail.l: Expected errors for the above two testcases. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v6t2-2.d: New testcase. * testsuite/gas/arm/copro-arm_v5teplus-arm_v5.d: New testcase. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v4t-3.d: New testcase. * testsuite/gas/arm/copro-arm_v5teplus-thumb_v6t2plus-unavail.l: Expected errors for the above two testcases. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v6t2-3.d: New testcase. * testsuite/gas/arm/copro-arm_v6plus-arm_v5te.d: New testcase. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v4t-4.d: New testcase. * testsuite/gas/arm/copro-arm_v6plus-thumb_v6t2plus-unavail.l: Expected errors for the above two testcases. * testsuite/gas/arm/copro-thumb_v6t2plus-thumb_v6t2-4.d: New testcase.

2017-10-31Use console uiout when executing breakpoint commandsSimon Marchi4-6/+31
As reported here https://sourceware.org/ml/gdb/2017-10/msg00020.html the output of certain commands, like backtrace, doesn't appear anywhere when it is run as a breakpoint command and when using MI. The reason is that the current_uiout is set to the mi_ui_out while these commands run, whereas we want the output as CLI output. Some commands like "print" work, because they use printf_filtered (gdb_stdout, ...) directly, bypassing the current ui_out. The fix I did is to force setting the cli_uiout as the current_uiout when calling execute_control_command. I am not sure if this is the right way to fix the problem, comments about the approach would be appreciated. I enhanced gdb.mi/mi-break.exp to test the backtrace command. Regtested on the buildbot. gdb/ChangeLog: * cli/cli-script.c (execute_control_command): Rename to ... (execute_control_command_1): ... this.

When compiling with clang or gcc 8, we see warnings like this: /home/emaisin/src/binutils-gdb/gdb/arm-tdep.c:10013:13: error: comparison of 0 <= unsigned expression is always true [-Werror,-Wtautological-compare] if (0 <= insn_op1 && 3 >= insn_op1) ~ ^ ~~~~~~~~ /home/emaisin/src/binutils-gdb/gdb/arm-tdep.c:11722:20: error: comparison of unsigned expression >= 0 is always true [-Werror,-Wtautological-compare] else if (opB >= 0 && opB <= 2) ~~~ ^ ~ This is because an unsigned integer (opB in this case) will always be >= 0.

This allows reusing a std::string's memory buffer across several calls, for example. gdb/ChangeLog: 2017-10-30 Pedro Alves <palves@redhat.com> * common/common-utils.c (string_appendf, string_vappendf): New functions. * common/common-utils.h (string_appendf, string_vappendf): New declarations. * unittests/common-utils-selftests.c (string_appendf_func) (test_appendf_func, string_vappendf_wrapper, string_appendf_tests) (string_vappendf_tests): New functions. (_initialize_common_utils_selftests): Register "string_appendf" and "string_vappendf tests".

Merge the string_printf and string_vprintf tests, running them all against both functions. gdb/ChangeLog: 2017-10-30 Pedro Alves <palves@redhat.com> * unittests/common-utils-selftests.c (format_func): New typedef. (string_printf_tests, string_vprintf_tests): Tests factored out and merged to ... (test_format_func): ... this new function. (string_printf_tests, string_vprintf_tests): Reimplement on top of test_format_func.

2017-10-30relocs_compatible test for gc-sectionsAlan Modra2-0/+8
I noticed when looking at pr22300 that before calling check_relocs we have an elf_object_id test (added for pr11933) as well as the relocs_compatible test. I believe backend gc_mark_hook and gc_sweep_hook ought to be protected similarly from being confused by unexpected relocations (for example, both elf64-ppc.c and elf32-ppc.c use _bfd_elf_relocs_compatible, so I think it would be possible for the ppc64 gc_mark_hook to be presented with a ppc32 relocatable object). * elflink.c (elf_gc_sweep): Test elf_object_id in addition to relocs_compatible. (bfd_elf_gc_sections): Likewise.

Adds UNDEFWEAK_NO_DYNAMIC_RELOC in the rest of places needed in this file, reduces dynamic relocations in a number of cases, and removes some bogus code that was attempting to handle dynamic common symbols specially. PR 22269 * elf32-hppa.c (elf32_hppa_check_relocs): Move SEC_ALLOC test to ensure non_got_ref is not set due to debug references. (elf32_hppa_adjust_dynamic_symbol): Tidy plabel handling. Use SYMBOL_CALLS_LOCAL and UNDEFWEAK_NO_DYNAMIC_RELOC when determining need for a plt entry. (allocate_dynrelocs): Similarly for got entries. Tidy code discarding dynamic relocs when pic. Remove bogus code attempting to handle commons. (elf32_hppa_relocate_section): Similarly. Delete resolved_to_zero and simplify. (elf32_hppa_finish_dynamic_symbol): Use UNDEFWEAK_NO_DYNAMIC_RELOC and SYMBOL_REFERENCES_LOCAL in GOT handling.

2017-10-28Make gdb.selected_thread().inferior return a new referenceMaksim Dzabraev4-0/+22
thpy_get_inferior function should return a new reference to the existing inferior object, and therefore should increment its refcount. Fixed bug looks like this. If multiple time call gdb.selected_thread ().inferior, gdb throws exception: (gdb) pi gdb.selected_thread().inferior <gdb.Inferior object at 0x7f1952bea698> (gdb) pi gdb.selected_thread().inferior Python Exception <type 'exceptions.AttributeError'> 'NoneType' object has no attribute 'inferior': Error while executing Python code.

2017-10-28PR22300, Abort in elf32_hppa_relocate_section building polymlAlan Modra5-5/+11
polyml produces object files with the wrong OS/ABI for hppa-linux. This, along with the fact that elf32-hppa.c is using the strictest backend relocs_compatible, results in wrong merging of ELF symbols. So, remove the relocs_compatible check in _bfd_elf_merge_symbol. _bfd_elf_merge_symbol is only called nowadays from within blocks protected by is_elf_hash_table, so "we are doing an ELF link" as the removed comment says, is true. Also relax relocs_compatible for hppa and powerpc. relocs_compatible is used for more than just merging symbols, as the name suggests. This allows objects that are in fact reasonably compatible to be linked. PR 22300 * elflink.c (_bfd_elf_merge_symbol): Remove relocs_compatible check. * elf32-hppa.c (elf_backend_relocs_compatible): Define. * elf32-ppc.c (elf_backend_relocs_compatible): Define. * elf64-ppc.c (elf_backend_relocs_compatible): Define.
