2017-02-20DWARF-5: NEWSJan Kratochvil2-0/+7
a NEWS entry. gdb/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * NEWS (Changes since GDB 7.12): Add DWARF-5.
2017-02-20DWARF-5: DW_FORM_data16Jan Kratochvil6-1/+140
DWARF-5 has new form DW_FORM_data16. The problem is that GDB cannot pass 16-byte constant as a constant value as that would require GDB to use GCC extension __int128. Formerly such data was coded as DW_FORM_block* so GDB still decodes DW_FORM_data16 like DW_FORM_block*. gdb/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * dwarf2read.c (skip_one_die, read_attribute_value) (dwarf2_const_value_attr, dump_die_shallow) (dwarf2_get_attr_constant_value, dwarf2_fetch_constant_bytes) (skip_form_bytes, attr_form_is_constant): Handle DW_FORM_data16. gdb/testsuite/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.dwarf2/formdata16.c: New file. * gdb.dwarf2/formdata16.exp: New file. * lib/dwarf.exp (Dwarf): Add DW_FORM_data16.

2017-02-20Code cleanup: Split dwarf2_ranges_read to a callbackJan Kratochvil2-85/+49
DWARF-5 has .debug_rnglists which is somehow similar to .debug_ranges. This patch converts dwarf2_ranges_read to dwarf2_ranges_process which can work with both DWARF kinds of range lists through a callback. It also simplifies dwarf2_record_block_ranges which can benefit from it. gdb/ChangeLog 2017-02-20 Jan Kratochvil <jan.kratochvil@redhat.com> * dwarf2read.c (dwarf2_ranges_process): New function from dwarf2_ranges_read.

2017-02-20PR gdb/16188: Verify PTRACE_TRACEME succeededSergio Durigan Junior6-8/+67
This patch fixes PR gdb/16188, which is about the fact that fork_inferior doesn't verify the return value of the "traceme_fun" callback. On most targets, this callback is actually a wrapper to a ptrace call that does a PTRACE_TRACEME on the forked GDB process that will eventually become the inferior. Thanks to Pedro, this second version of the patch is simpler and more more logical. Basically, two helper functions are added: trace_start_error and trace_start_error_with_name. The former can be used when there is a customized error message to be printed to the user. The latter works like perror_with_name, so you just need to pass the function that error'd. Both helper functions mentioned above do basically the same thing: print the error message to stderr and call _exit, properly terminating the forked inferior. Most of the patch takes care of guarding the necessary system calls against errors on the "traceme_fun" callbacks. It is not right to call error on these situations, so I've replaced these calls with the proper helper function call. Regression-tested on BuildBot.

2017-02-17GAS: Add ECOFF `.aent' pseudo-op supportMaciej W. Rozycki8-14/+76
Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section support with ELF objects and, for consistency, also with ECOFF objects. This is so that the same MIPS source can be assembled without and with `.mdebug' section generation enabled. Taking the `gas/testsuite/gas/mips/aent.s' test case source as an example and the `mips-linux' target we have: $ as -o aent.o aent.s $ as -mdebug -o aent.o aent.s aent.s: Assembler messages: aent.s:10: Error: unknown pseudo-op: `.aent' $ because for the !ECOFF_DEBUGGING case (which is the default) the pseudo-op is already handled by the MIPS backend with `s_mips_ent', however no handler is present for the opposite case. For the MIPS target this is a functional regression introduced with commit ecb4347adecd ("Last take: approval for MIPS_STABS_ELF killing"), <https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where support for the `.mdebug' section was added along with its associated `-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency between the assembly syntax supported for each of these options as far as the `.aent' pseudo-op is concerned. Assembly language documentation available describes the pseudo-op respectively as follows[1]: " .aent name, symno Sets an alternate entry point for the current procedure. Use this information when you want to generate information for the debugger. It must appear inside an .ent/.end pair." and[2]: " .aent name [,symno] Sets an alternate entry point for the current procedure. Use this information when you want to generate information for the debugger. This directive must appear between a pair of .ent and .end directives. (The optional symno is for compiler use only. It refers to a dense number in a .T file (symbol table).)" Copy the approach from `s_mips_ent' then and add `.aent' support to the `.ent' pseudo-op handler shared between the ELF and ECOFF object file format backends, by setting BSF_FUNCTION for the symbol requested.

2017-02-17Add support for Intel PKRU register to GDB and GDBserver.Michael Sturm40-133/+560
This patch adds support for the registers added by the Memory Protection Keys for Userspace (PKU aka PKEYs) feature. Native and remote debugging are covered by this patch. The XSAVE area is extended with a new state containing the 32-bit wide PKRU register. The new register is added to amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also, respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set it supports.

2017-02-17Add target description for avx-avx512.Michael Sturm32-301/+1712
Add a dedicated target description for the feature combination avx-avx512 as implemented by certain IA CPU models. The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers displayed as undefined on CPUs that only implemented X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue. This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx-avx512-linux.c): New include.

2017-02-17Rename target descriptions to reflect actual content of description.Michael Sturm33-166/+174
To better reflect the actual feature set covered by the IA target descriptions, the existing descriptions are renamed. Each feature of the extended state is added to the name of a description or xstate mask starting from AVX. For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux, while amd64-avx-linux remains unchanged. Likewise, the corresponding xstate masks are changed, e.g. from X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx512-linux.c): Rename include to...

2017-02-17Change xstate_bv handling to use 8 bytes of data.Michael Sturm2-16/+25
The size of the state-component bitmap as specified in Intel(R) 64 and IA-32 Architectures Software Developer's Manual, Chapter 13.4.2 is 8 bytes. So far, the data types used for xstate_bv_p (gdb_byte*), clear_bv (unsigned int) and tdep->xcr0 (uint64_t) were inconsistent. But, since the xstate components were still fitting into a single byte, the code still worked as expected. However, with the addition of the PKU feature (bit 9), using one byte for the bitmap will no longer be sufficient. This patch changes related code to use 64 bit data types consistently and changes read/write acces of the XSAVE header in the xsave buffer to use the endianess-aware functions extract_unsigned_integer and store_unsigned_integer. This is required to make sure that eventual differences in endianess between host and target are taken care off. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * i387-tdep.c (i387_supply_xsave): Change type of clear_bv to ULONGEST.

2017-02-16bfd: Improve lookup of file / line information for errorsAndrew Burgess5-6/+49
When looking up file and line information (used from the linker to report error messages) if no symbol is passed in, then use the symbol list to look for a matching symbol. If a matching symbol is found then use this to look up the file / line information. This should improve errors when looking up file / line information for data sections. Hopefully we should find a matching data symbol, which should, in turn (we hope) match a DW_TAG_variable in the DWARF, this should allow us to give accurate file / line errors for data symbols. As the hope is to find a matching DW_TAG_variable in the DWARF then we ignore section symbols, and prefer global symbols to locals. bfd/ChangeLog: * dwarf2.c (_bfd_dwarf2_find_nearest_line): Perform symbol lookup before trying to fine matching file and line information. ld/ChangeLog: * testsuite/ld-elf/shared.exp: Update expected results. * testsuite/ld-elf/dwarf2.err: Likewise
2017-02-16bfd/dwarf: Improve use of previously loaded dwarf informationAndrew Burgess9-2/+84
When parsing DWARF data in order to report file/line type error messages we perform section placement to make section addresses unique within relocatable object files. Currently, if we reuse previously loaded (and cached) dwarf data then we neglect to perform section placement, the result is that the section addresses will not be unique, and we might, incorrectly associate an address with the wrong debug information, and so report an incorrect file and line number. Further we neglect to check that that bfd for which we are looking up debug information is actually the bfd for which the previous debug information was loaded, it is possible that we will reuse previously loaded debug information for a different bfd. And finally, due to following of gnu_debuglink links in one bfd to another, the process of checking that the cached debug information is valid requires us to track the original bfd in the cached debug information. The original debug information here is either the bfd that we're interested in, not the bfd we finally load the debug information from. bfd/ChangeLog: * dwarf2.c (struct dwarf2_debug): Add orig_bfd member. (_bfd_dwarf2_slurp_debug_info): If stashed debug information does not match current bfd, then reload debug information. Record bfd we're loading debug info for in the stash. If we have debug informatin in the cache then perform section placement before returning. ld/ChangeLog: * testsuite/ld-elf/dwarf.exp (build_tests): Add new tests. * testsuite/ld-elf/dwarf2.err: New file. * testsuite/ld-elf/dwarf2a.c: New file. * testsuite/ld-elf/dwarf2b.c: New file. * testsuite/ld-elf/dwarf3.c: New file. * testsuite/ld-elf/dwarf3.err: New file.
2017-02-16ld: Add additional checking for warnings/errors in testsuiteAndrew Burgess4-16/+84
This commit adds new actions to the run_cc_link_tests mechanism in the linker testsuite. Previously this procedure could take a parameter containing a regular expression that would be matched against warnings from the linker. After this commit the warnings parameter is removed, instead, the actions list can contain the actions 'warning', 'error', 'warning_output', or 'error_output'. The action names are chosen to match the actions already present in the run_dump_test procedure. These new actions allow for the current warning checking, but also allow for checking of errors using a regular expression. More interestingly, the *_output actions allow for the warning/error patterns to be placed in a separate file. The small number of tests that make use of the warning parameter have been updated to the new mechanism. Later commits will make use of the new features added in this commit. ld/ChangeLog: * testsuite/lib/ld-lib.exp (run_cc_link_tests): Add warning, error, warning_output, and error_output actions. Remove separate warnings parameter. * testsuite/ld-elf/shared.exp (build_tests): Updated to use 'warning' action. * testsuite/ld-plugin/lto.exp (lto_link_tests): Likewise.
