2018-07-06Add checks for the NT_ARM_SVE section in a core file.Alan Hayward3-0/+37
The NT_ARM_SVE section is documented here: https://github.com/torvalds/linux/blob/master/Documentation/arm64/sve.txt * A NT_ARM_SVE note will be added to each coredump for each thread of the dumped process. The contents will be equivalent to the data that would have been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread when the coredump was generated. * elf.c (elfcore_grok_aarch_sve): New function. (elfcore_grok_note): Check for Aarch64 SVE. (elfcore_write_aarch_sve): New function. (elfcore_write_register_note): Check for Aarch64 SVE. * elf-bfd.h(elfcore_grok_aarch_sve): New declaration.
2018-07-06Fix SBO bit in disassembly mask for ldrah on AArch64.Tamar Christina2-1/+6
The disassembly mask for ldarh incorrectly didn't mask out bit 20 which is part of the SBO part of the instruction and shouldn't be considered input. This fixes the wrong bit fixing the disassembly of instructions to ldarh and makes the behavior consistent. opcodes/ PR binutils/23242 * aarch64-tbl.h (ldarh): Fix disassembly mask.
2018-07-06Fix the read/write flag for these registers on AArch64Tamar Christina5-5/+44
The previous constraints were based on information already in opcodes and it seems that a few of them were wrong. I have now hand verified the ones changed by the previous patch and corrected where needed. This prevents a warning to be issued when one shouldn't be. opcodes/ PR binutils/23369 * aarch64-opc.c (aarch64_sys_regs): Make read/write csselr_el1, vsesr_el2, osdtrrx_el1, osdtrtx_el1, pmsidr_el1. gas/testsuite/ PR binutils/23369 * gas/aarch64/msr.d (csselr_el1, vsesr_el2, osdtrrx_el1, osdtrtx_el1, pmsidr_el1): New. * gas/aarch64/msr.s: Likewise.
2018-07-06gdb/testsuite: Ensure test links in malloc and freeAndrew Burgess2-0/+8
The test associated with the source file gdb.base/share-env-with-gdbserver.c relies on calling malloc and free within the inferior from GDB. However, as the test source itself makes no use of these functions, there's no requirement that they be linked into the test executable. This commit adds a dummy call to malloc and free to ensure they are linked into the test executable. gdb/testsuite/ChangeLog: * gdb.base/share-env-with-gdbserver.c (main): Add call to malloc/free.

2018-07-05[gdb] Fix build error in macroexp.cTom de Vries2-0/+14
When doing a combined build with the gcc and binutils-gdb repos, I run into this build error in gdb: ... gdb/macroexp.c: \ In function ‘void get_next_token_for_substitution(macro_buffer*, \ macro_buffer*, char**, macro_buffer*, char**, int*, bool*)’: gdb/macroexp.c:925:17: error: \ implicitly-declared ‘constexpr macro_buffer& \ macro_buffer::operator=(const macro_buffer&)’ is deprecated \ [-Werror=deprecated-copy] *token = *lookahead; ... Wdeprecated-copy is a new gcc warning added after gcc 8. This patch fixes the build error by adding an explicit copy operator to the macro_buffer class. I've added asserts to ensure that both the dest and src of the copy are shared, in other words, neither is owner of the text pointer. I've run the gdb testsuite on x86_64-linux and the asserts did not trigger. 2018-07-05 Tom de Vries <tdevries@suse.de> * macroexp.c (macro_buffer) <operator=>: New member function.

2018-07-04darwin: Don't use sbrkSimon Marchi5-4/+20
This patch gets rid of this warning on macOS: CXX main.o /Users/simark/src/binutils-gdb/gdb/main.c:492:27: error: 'sbrk' is deprecated [-Werror,-Wdeprecated-declarations] lim_at_start = (char *) sbrk (0); ^ /usr/include/unistd.h:585:1: note: 'sbrk' has been explicitly marked deprecated here __deprecated __WATCHOS_PROHIBITED __TVOS_PROHIBITED ^ /usr/include/sys/cdefs.h:176:37: note: expanded from macro '__deprecated' #define __deprecated __attribute__((deprecated)) ^ sbrk on macOS is not useful for our purposes, since sbrk(0) always returns the same value. From what I read, brk/sbrk on macOS is just an emulation, it always returns a pointer in a 4MB section reserved for that. So instead of letting users use "maint set per-command space on" and print silly results, I think we should just disable that feature for this platform (as we do for platforms that don't have sbrk). I defined a HAVE_USEFUL_SBRK macro and used that instead of HAVE_SBRK. gdb/ChangeLog: * common/common-defs.h (HAVE_USEFUL_SBRK): Define. * main.c: Use HAVE_USEFUL_SBRK instead of HAVE_SBRK. * maint.c: Likewise. * top.c: Likewise.

2018-07-04Warn if /proc is not accessiblegdb-8.2-branchpointVyacheslav Barinov6-5/+45
There's a buildroot where I want to debug a binary, and I tried to connect to it from outside, but got very weird errors like architecture mismatch or protocol errors. At last, after switching on '--debug' for gdbserver I found a message 'Can't open /proc/pid/' message and suddenly found that I forgot to mount procfs in my buildroot. Make discovering the problem easier by making GDB / GDBserver warn (even without --debug) if /proc can not be accessed.

2018-07-03Remove exit_inferior_num_silentTom Tromey3-9/+7
The sole caller of exit_inferior_num_silent was getting the inferior's number to then use the number to look up the inferior again. I think it's better to simply not have exit_inferior_num_silent; any potential callers that only have the inferior's number should probably be converted to pass the inferior itself around instead. Tested by the buildbot. gdb/ChangeLog 2018-07-03 Tom Tromey <tom@tromey.com> * infrun.c (follow_exec): Use exit_inferior_silent. * inferior.c (exit_inferior_num_silent): Remove. * inferior.h (exit_inferior_num_silent): Don't declare.
2018-07-03Fix crash in "run" on macOS when gdb is not signedTom Tromey2-52/+73
On macOS, when gdb is not code-signed, it will throw an exception from darwin_attach_pid. However, gdb also then crashes: thread.c:93: internal-error: struct thread_info *inferior_thread(): Assertion `tp' failed. I think the problem here is that darwin_attach_pid does not clean up inferior_ptid and inf->pid on failure. This leads to a situation where gdb tries to find a thread, but cannot. In other cases, gdb would mourn the inferior at this point; but here this is not possible because the target has not been pushed. Instead this patch works by simply updating the inferior and inferior_ptid on failure. Tested by building an unsigned gdb on macOS and trying to run an inferior. gdb/ChangeLog 2018-07-03 Tom Tromey <tom@tromey.com> PR cli/23340: * darwin-nat.c (darwin_attach_pid): Reset inferior and inferior_ptid on error.
2018-07-03Correct removal of .gnu.attributesAlan Modra2-7/+16
Setting SEC_EXCLUDE for empty .gnu.attributes is too late in the link process for the linker to remove the section. That must be done in bfd_elf_final_link, as we do for removed group sections. * elflink.c (bfd_elf_final_link): Remove zero size .gnu.attributes sections.
2018-07-03GNU attribute output on errorsAlan Modra5-58/+109
.gnu.attributes entries from linker input files are merged to the output file, the output having the union of compatible input attributes. Incompatible attributes generally cause a linker error and no output. However in some cases only a warning is emitted, and one of the incompatible input attributes is passed on to the output. PowerPC tends to emit warnings rather than errors, and the output takes the first input attribute. For example, if we have two input files with Tag_GNU_Power_ABI_FP, the first with a value signifying "double-precision hard float, IBM long double", the second with a value signifying "double-precision hard float, IEEE long double", we'll get a warning about incompatible long double types and the output will say "double-precision hard float, IBM long double". The output attribute of course isn't correct. It would be correct to specify "IBM and IEEE long double", but we don't have a way to represent that currently. While it would be possible to extend the encoding, there isn't much gain in doing so. A shared library providing support for both long double types should link against objects using either long double type without warning or error. That is what you'd get if such a shared library had no Tag_GNU_Power_ABI_FP attribute. So this patch provides a way for the backend to omit .gnu.attributes tags from the output. * elf-bfd.h (ATTR_TYPE_FLAG_ERROR, ATTR_TYPE_HAS_ERROR): Define. * elf-attrs.c (is_default_attr): Handle ATTR_TYPE_HAS_ERROR. * elf32-ppc.c (_bfd_elf_ppc_merge_fp_attributes): Use ATTR_TYPE_FLAG_INT_VAL.

2018-07-03Hide dynamic symbols in discarded sectionsAlan Modra2-2/+12
This is a followup to git commit 97196564c7 "Strip global symbol defined in discarded section". If a symbol defined in a discarded section was dynamic, that patch left .dynsym with holes (ie. all zero entries). For example, the following from libstdc++.so: Symbol table '.dynsym' contains 6090 entries: Num: Value Size Type Bind Vis Ndx Name 0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000000a74e0 0 SECTION LOCAL DEFAULT 10 2: 0000000000264180 0 SECTION LOCAL DEFAULT 17 3: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_addUserCommitAction 4: 0000000000000000 0 NOTYPE WEAK DEFAULT UND _ITM_memcpyRtWn 5: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 5 found at index >= .dynsym's sh_info value of 3 6: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND readelf: Warning: local symbol 6 found at index >= .dynsym's sh_info value of 3 [snip] This patch removes the symbols from .dynsym too.
