2018-06-21Enable hardware watchpoints on attach for aarch64Richard Bunt5-0/+145
This commit fixes a bug whereby hardware watchpoints are not used on aarch64 when attaching to a target. The fix adds an aarch64 specialization of post_attach which records the number of available hardware debug registers using aarch64_linux_get_debug_reg_capacity. This implementation mirrors that of aarch64_linux_child_post_startup_inferior which successfully enables the use of hardware watchpoints when launching the target under the debugger. gdb/ChangeLog: * aarch64-linux-nat.c (post_attach): New. (aarch64_linux_nat_target::post_attach): Override post_attach to record the number of hardware debug registers. gdb/testsuite/ChangeLog: * gdb.base/watchpoint-hw-attach.c: New test. * gdb.base/watchpoint-hw-attach.exp: New file.

2018-06-20Rename regcache_cooked_read_ftype and make a function_viewSimon Marchi5-38/+47
regcache_cooked_read_ftype can be converted to a function_view, which allows us to use lambda functions and therefore avoid having to pass an opaque pointer parameter. Adjusting the fallouts showed that the "const regcache &" passed to the readonly_detached_regcache constructor is cast to non-const in do_cooked_read. I changed the constructor parameter to be non-const. Finally, I renamed the typedef from regcache_cooked_read_ftype to register_read_ftype, since there is nothing that forces us to use it only for regcaches nor cooked registers. gdb/ChangeLog: * regcache.h (regcache_cooked_read_ftype): Rename to...

2018-06-20PR ld/22966: Fix n64 MIPS `.got.plt' range checksMaciej W. Rozycki16-2/+300
The addressable signed 32-bit range for n64 MIPS `.got.plt' references is from 0xffffffff7fff8000 to 0x7fff7fff, due to how the composition of an LUI and an LD instruction works for address calculation in the 64-bit addressing mode, such as when CP0.Status.UX=1. We currently have a range check in `mips_finish_exec_plt', however it is not correct as it verifies that the `.got.plt' start address referred is between 0xffffffff80000000 and 0x7fffffff. It is also implemented as an assertion rather than a proper error message despite that the situation can be triggered by user input. Additionally there is no check made for individual `.got.plt' entries referred even though they can be out of range while the `.got.plt' start address is not. Fix all these problems and use the correct range for the check, limiting it to n64 output files, and then issue a proper error message both in `mips_finish_exec_plt' and in `_bfd_mips_elf_finish_dynamic_symbol', suggesting the use of the `-Ttext-segment=...' option that will often work and with the default linker scripts in particular. Add suitable tests covering boundary cases. bfd/ PR ld/22966 * elfxx-mips.c (_bfd_mips_elf_finish_dynamic_symbol): Verify the `.got.plt' entry referred is in range.

2018-06-20MIPS/LD/testsuite: XFAIL DT_TEXTREL map file warning testMaciej W. Rozycki2-1/+11
Remove: FAIL: DT_TEXTREL map file warning introduced with commit 63c1f59d6655 ("readonly_dynrelocs"), coming from the lack of a "dynamic relocation against `foo' in read-only section `.rodata'" warning message produced. The cause of the failure is that for sections which have dynamic relocations attached the MIPS backend sets SHF_WRITE, in `mips_elf_create_dynamic_relocation', yielding: $ readelf -S textrel.so | grep rodata [ 8] .rodata PROGBITS 00000254 000254 000004 00 WA 0 0 1 $ so the section is read/write and therefore there is nothing to warn about. This arrangement came from commit 7403cb6305f5 ("PATCH for N32 ABI"), <https://sourceware.org/ml/binutils/1999-q2/msg00375.html>, i.e. for all practical purposes it has been there since forever, and therefore it can be considered a part of the ABI and the test case irrelevant for MIPS targets. We don't have a clean way to request UNSUPPORTED result, which would be the most appropriate here, so just XFAIL the test instead. ld/ * testsuite/ld-elf/shared.exp: XFAIL DT_TEXTREL map file warning test for `mips*-*-*'.
2018-06-19Bump to autoconf 2.69 and automake 1.15.1Simon Marchi243-38438/+48835
When trying to run the update-gnulib.sh script in gdb, I get this: Error: Wrong automake version (Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ =:+{}]+)}/ at /opt/automake/1.11.1/bin/automake line 4113.), we need 1.11.1. Aborting. Apparently, it's an issue with a regex in automake that triggers a warning starting with Perl 5.22. It has been fixed in automake 1.15.1. So I think it's a good excuse to bump the versions of autoconf and automake used in the gnulib import. And to avoid requiring multiple builds of autoconf/automake, it was suggested that we bump the required version of those tools for all binutils-gdb. For autoconf, the 2.69 version is universally available, so it's an easy choice. For automake, different distros and distro versions have different automake versions. But 1.15.1 seems to be the most readily available as a package. In any case, it's easy to build it from source. I removed the version checks from AUTOMAKE_OPTIONS and AC_PREREQ, because I don't think they are useful in our case. They only specify a lower bound for the acceptable version of automake/autoconf. That's useful if you let the user choose the version of the tool they want to use, but want to set a minimum version (because you use a feature that was introduced in that version). In our case, we force people to use a specific version anyway. For the autoconf version, we have the check in config/override.m4 that enforces the version we want. It will be one less thing to update next time we change autotools version. I hit a few categories of problems that required some changes. They are described below along with the chosen solutions. Problem 1: configure.ac:17: warning: AM_INIT_AUTOMAKE: two- and three-arguments forms are deprecated. For more info, see: configure.ac:17: http://www.gnu.org/software/automake/manual/automake.html#Modernize-AM_005fINIT_005fAUTOMAKE-invocation Solution 1: Adjust the code based on the example at that URL.

Problem 8: Makefile.am:131: warning: source file 'config/tc-aarch64.c' is in a subdirectory, Makefile.am:131: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled.

2018-06-19Silence -Wmaybe-uninitialized warning in ↵Pedro Alves2-13/+28
minsyms.c:lookup_minimal_symbol_by_pc_section Compiling with GCC 8.1 shows this warning: gdb/minsyms.c: In function 'bound_minimal_symbol lookup_minimal_symbol_by_pc_section(CORE_ADDR, obj_section*, lookup_msym_prefer)': gdb/minsyms.c:825:40: warning: 'want_type' may be used uninitialized in this function [-Wmaybe-uninitialized] && MSYMBOL_TYPE (&msymbol[hi]) != want_type That warning is a false positive, because the switch that converts enum lookup_msym_prefer values to enum enum minimal_symbol_type values has a case for every lookup_msym_prefer enumerator: switch (prefer) { case lookup_msym_prefer::TEXT: want_type = mst_text; break; case lookup_msym_prefer::TRAMPOLINE: want_type = mst_solib_trampoline; break; case lookup_msym_prefer::GNU_IFUNC: want_type = mst_text_gnu_ifunc; break; } The problem is that GCC assumes that enum variables may hold values other than the named enumerators (like e.g., "lookup_msym_prefer prefer = (lookup_msym_prefer) 10;"). Rework the code a bit, adding a gdb_assert to make it explicit to the compiler that want_type is initialized in all normal-return paths. gdb/ChangeLog: 2018-06-19 Pedro Alves <palves@redhat.com> * minsyms.c (msym_prefer_to_msym_type): New, factored out from ...

2018-06-19Change inline frame breakpoint skipping logic (fix gdb.gdb/selftest.exp)Pedro Alves5-12/+87
Currently, gdb.gdb/selftest.exp fails if you build GDB with optimization (-O2, etc.). The reason is that after setting a breakpoint in captured_main, we stop at: ... Breakpoint 1, captured_main_1 (context=<optimized out>) at src/gdb/main.c:492 ... while selftest_setup expects a stop at captured_main. Here, captured_main_1 has been inlined into captured_main, and captured_main has been inlined into gdb_main: ... $ nm ./build/gdb/gdb | egrep ' [tT] .*captured_main|gdb_main' | c++filt 000000000061b950 T gdb_main(captured_main_args*) ... Indeed, the two inlined functions show up in the backtrace: ... (gdb) bt #0 captured_main_1 (context=<optimized out>) at main.c:492 #1 captured_main (data=<optimized out>) at main.c:1147 #2 gdb_main (args=args@entry=0x7fffffffdb80) at main.c:1173 #3 0x000000000040fea5 in main (argc=<optimized out>, argv=<optimized out>) at gdb.c:32 ... We're now stopping at captured_main_1 because commit ddfe970e6bec ("Don't elide all inlined frames") makes GDB present a stop at the innermost inlined frame if the program stopped by a user breakpoint. Now, the selftest.exp testcase explicitly asks to stop at "captured_main", not "captured_main_1", so I'm thinking that it's GDB'S behavior that should be improved. That is what this commit does, by only showing a stop at an inline frame if the user breakpoint was set in that frame's block. Before this commit: (top-gdb) b captured_main Breakpoint 1 at 0x792f99: file src/gdb/main.c, line 492. (top-gdb) r Starting program: build/gdb/gdb Breakpoint 1, captured_main_1 (context=<optimized out>) at src/gdb/main.c:492 492 lim_at_start = (char *) sbrk (0); (top-gdb) After this commit, we now instead get: (top-gdb) b captured_main Breakpoint 1 at 0x791339: file src/gdb/main.c, line 492. (top-gdb) r Starting program: build/gdb/gdb Breakpoint 1, captured_main (data=<optimized out>) at src/gdb/main.c:1147 1147 captured_main_1 (context); (top-gdb) and: (top-gdb) b captured_main_1 Breakpoint 2 at 0x791339: file src/gdb/main.c, line 492. (top-gdb) r Starting program: build/gdb/gdb Breakpoint 2, captured_main_1 (context=<optimized out>) at src/gdb/main.c:492 492 lim_at_start = (char *) sbrk (0); (top-gdb) Note that both captured_main and captured_main_1 resolved to the same address, 0x791339. That is necessary to trigger the issue in question. The gdb.base/inline-break.exp testcase currently does not exercise that, but the new test added by this commit does. That new test fails without the GDB fix and passes with the fix. No regressions on x86-64 GNU/Linux. While at it, the THIS_PC comparison in stopped_by_user_bp_inline_frame is basically a nop, so just remove it -- if a software or hardware breakpoint explains the stop, then it must be that it was installed at the current PC. gdb/ChangeLog: 2018-06-19 Pedro Alves <palves@redhat.com> * inline-frame.c (stopped_by_user_bp_inline_frame): Replace PC parameter with a block parameter. Compare location's block symbol with the frame's block instead of addresses. (skip_inline_frames): Pass the current block instead of the frame's address.

2018-06-18Remove la_errorTom Tromey30-68/+58
While working on the parser code, I noticed that yyerror is exported from each parser. It is used by this code in parse.c: TRY { if (lang->la_parser (&ps)) lang->la_error (NULL); } However, it seems to me that la_error will never be called here, because in every case, la_parser throws an exception on error -- each implementation of yyerror just calls error. So, this patch removes la_error and makes all the yyerror functions static. This is handy primarily because it makes it simpler to make the expression parsers pure.
