2018-04-23Remove a cleanup from scm-frame.cTom Tromey2-29/+30
This removes a cleanup from scm-frame.c, replacing it with unique_xmalloc_ptr and a new scope. I believe this also fixes a latent bug involving calling do_cleanups twice for a single cleanup.

2018-04-21FreeBSD: Fix 'Couldn't get registers: Device busy' error (PR gdb/23077)Pedro Alves3-2/+15
As Rajendra SY reported at <https://sourceware.org/ml/gdb-patches/2018-04/msg00399.html>, several attach-related tests are failing on FreeBSD. The "attach" command errors with "Couldn't get registers: Device busy". When the "attach" command is executed, it calls target_attach -> inf_ptrace_attach, which just does the ptrace(PT_ATTACH), it does not wait for the child to stop with SIGSTOP. Afterwards, the command is complete and we go back to the event loop. The event loop wakes up and we end up in target_wait -> fbsd_wait, and handle the SIGSTOP stop. At the end of execute_command, though, before going back to the event loop, we check if the frame language changed via check_frame_language_change(). That reads the current PC, which is what leads to the registers read that fails. The problem is that we fail to mark the attached-to thread as executing between the initial attach, and the subsequent target_wait. Until we see the thread stop with SIGSTOP, we shouldn't try to read registers off of it. I guess there may a timing issue here - if you're "lucky", the thread may stop before gdb reads its registers, masking the problem. With that fixed, check_frame_language_change() becomes a nop until the thread is marked not-executing again, after target_wait is called and we go through handle_inferior_event -> normal_stop. We haven't seen the problem on Linux because there, the target_attach implementation waits for the thread to stop before returning. Still, that's supposedly hidden from the core, since the Linux target, like most targets, is a '!to_attach_no_wait' target. This fixes: FAIL: gdb.base/attach.exp: attach1, after setting file FAIL: gdb.base/attach.exp: attach2, with no file FAIL: gdb.base/attach.exp: load file manually, after attach2 (re-read) (got interactive prompt) FAIL: gdb.base/attach.exp: attach when process' a.out not in cwd FAIL: gdb.base/dprintf-detach.exp: bai=on ds=gdb dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=gdb dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=call dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=call dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=agent dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=on ds=agent dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=gdb dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=gdb dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=call dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=call dd=off: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=agent dd=on: re-attach to inferior FAIL: gdb.base/dprintf-detach.exp: bai=off ds=agent dd=off: re-attach to inferior gdb/ChangeLog: 2018-04-21 Pedro Alves <palves@redhat.com> Rajendra SY <rajendra.sy@gmail.com> * inf-ptrace.c (inf_ptrace_attach): Mark the thread as executing. * remote.c (extended_remote_attach): In all-stop mode, mark the thread as executing.
2018-04-21Test that gcc -B picks up new ldAlan Modra2-0/+23
gcc configured using --with-ld always uses that particular version of ld if it exists. This patch adds a check that the ld version reported directly from ld-new matches that reported via gcc. I chose to compare the ld --version output rather than a more strict test (for example by gcc --print-prog-name=ld), because the version test allows a user to run the ld testsuite after installing a new ld (in the place expected by gcc). Sample output: Running target unix Using /usr/share/dejagnu/baseboards/unix.exp as board description file for target. Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.

2018-04-20PR22978, TLS local-dynamic incorrectly linked on hppa-linuxAlan Modra2-32/+48
We were emitting dynamic relocs on the second word of a TLS GD GOT entry pair (the dtprel offset), without the addend necessary when no symbol is present on the dynamic reloc. Unfortunately the simple solution of providing the proper addend doesn't work due to an hppa glibc ld.so bug that ignores such addends. So instead optimize the relocs. The dtprel offset is known at link time for locally defined symbols (the only case where we'll end up with no symbol on a dynamic reloc) so we can omit the dynamic reloc in that case. Furthermore, we can omit a dynamic reloc on the first word of a TLS GD GOT entry pair (the module id) if the symbol is local and we are producing an executable. Similarly, a tprel reloc on a TLS IE GOT entry is not needed for local symbols in an executable. So the condition for TLS GOT relocs can become bfd_link_dll(info) rather than bfd_link_pic(info) as needed for normal GOT relocs. This all presumes hppa ld.so doesn't need to differentiate TLS GD GOT pairs from TLS LD GOT pairs, which is currently true. PR 22978 * elf32-hppa.c (got_relocs_needed): Add extra param to special case both dtprel and tprel relocs. (allocate_dynrelocs): Adjust conditions for got relocs. (elf32_hppa_relocate_section): Likewise for local sym got relocs. Emit dynamic relocs on TLS GOT entries for shared libraries, not when pic. Omit dynamic reloc on dtprel entry when local, and on tprel entry when local and executable.

2018-04-19Add test case for a known hang in infrunRichard Bunt3-0/+188
The hang occurs when GDB tries to call inferior functions on two different threads with scheduler-locking turned on. The first call works fine, with the call to infrun_async(1) causing the signal_handler to be marked and the event to be handled, but then the event loop resets the "ready" member to zero, while leaving infrun_is_async set to 1. As a result, GDB hangs if the user switches to another thread and calls a second function because calling infrun_async(1) a second time has no effect, meaning the inferior call events are never handled. The added test case provokes the above issue. gdb/testsuite/ChangeLog: * gdb.threads/multiple-successive-infcall.c: New test. * gdb.threads/multiple-successive-infcall.exp: New file.

2018-04-19Fix dependency tracking in gdbserver subdirectoriesSimon Marchi2-2/+11
The dependency tracking (the thing that knows which source file included which other source file during last build to know what to rebuild when an included file changes) is broken for gdbserver subdirectories (arch and common). The dependency tracking files are created in the form arch/.deps/i386.Po but we try to include .deps/arch/i386.Po An easy smoke test is too "touch" the gdb/features/i386/32bit-core.c file in the source directory and try to rebuild gdbserver. This file is included by gdb/arch/i386.c, so it should cause gdb/gdbserver/arch/i386.o in the build directory to be rebuilt. It currently isn't rebuilt, but is with this patch applied. This patch copies the technique used in GDB to transform the dep file paths to the proper form. Also, while testing using the depcomp method of dependency tracking (by just hacking the condition), I noticed that depcomp was not found. The path to depcomp seems to be missing a "..". gdb/gdbserver/ChangeLog: * Makefile.in (depcomp): Add "..". (all_deps_files): New and use it.

2018-04-17[MicroBlaze] PIC data text relativeMichael Eager15-26/+246
Andrew Sadek <andrew.sadek.se@gmail.com> A new implemented feature in GCC Microblaze that allows Position Independent Code to run using Data Text Relative addressing instead of using Global Offset Table. Its aim was to make 'PIC' more efficient and flexible as elf size excess performance overhead were noticed when using GOT due to the indirect addressing. include/ChangeLog: * bfdlink.h (Add flag): Add new flag @ 'bfd_link_info' struct. * elf/microblaze.h (Add 3 new relocations): R_MICROBLAZE_TEXTPCREL_64, R_MICROBLAZE_TEXTREL_64 and R_MICROBLAZE_TEXTREL_32_LO for relax function. bfd/ChangeLog: * bfd/reloc.c (2 new BFD relocations): BFD_RELOC_MICROBLAZE_64_TEXTPCREL & BFD_RELOC_MICROBLAZE_64_TEXTPCREL * bfd/bfd-in2.h: Regenerate * bfd/libbfd.h: Regenerate * bfd/elf32-microblaze.c (Handle new relocs): define 'HOWTO' of 3 new relocs and handle them in both relocate and relax functions. (microblaze_elf_reloc_type_lookup): add mapping between for new bfd relocs. (microblaze_elf_relocate_section): Handle new relocs in case of elf relocation. (microblaze_elf_relax_section): Handle new relocs for elf relaxation. gas/ChangeLog: * gas/config/tc-microblaze.c (Handle new relocs directives in assembler): Handle new relocs from compiler output. (imm_types): add new imm types for data text relative addressing TEXT_OFFSET, TEXT_PC_OFFSET (md_convert_frag): conversion for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (md_apply_fix): apply fix for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (md_estimate_size_before_relax): estimate size for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL (tc_gen_reloc): generate relocations for BFD_RELOC_MICROBLAZE_64_TEXTPCREL, BFD_RELOC_MICROBLAZE_64_TEXTPCREL ld/ChangeLog: * ld/lexsup.c (Add 2 ld options): (ld_options): add disable-multiple-abs-defs @ 'ld_options' array (parse_args): parse new option and pass flag to 'link_info' struct. * ld/ldlex.h (Add enum): add new enum @ 'option_values' enum. * ld/ld.texinfo (Add new option): Add description for 'disable-multiple-abs-defs' * ld/main.c: Initialize flags with false @ 'main'. Handle disable-multiple-abs-defs @ 'mutiple_definition'.
2018-04-17Conditionally drop the discriminant field in quirk_rust_enumTom Tromey2-3/+11
While debugging the crash that Jan reported, I noticed that in some situations we could end up with a situation where one branch of a Rust enum type ended up with a field count of -1. The fix is simple: only conditionally drop the discriminant field when rewriting the enum variants. I couldn't find a way to test this; I only noticed it while debugging the DWARF reader. 2018-04-17 Tom Tromey <tom@tromey.com> * dwarf2read.c (quirk_rust_enum): Conditionally drop the discriminant field.

Regression tested on Fedora 26 x86-64. 2018-04-17 Tom Tromey <tom@tromey.com> * dwarf2read.c (quirk_rust_enum): Handle unions correctly. 2018-04-17 Tom Tromey <tom@tromey.com> * gdb.rust/simple.rs (Union): New type. (main): New local "u". * gdb.rust/simple.exp (test_one_slice): Add new test case.
2018-04-17Don't print symbol declaration's line number in rbreak outputAndreas Arnez2-16/+28
This commit: b744723f57 -- Show line numbers in output for "info var/func/type" adds the symbol declaration's line number to the output of certain GDB commands. It also (inadvertently) changes the `rbreak' command's output, like this: (gdb) rbreak foo Breakpoint 1 at 0x40049b: file rbreak.c, line 6. 4: static int foo1(void); Breakpoint 2 at 0x4004b1: file rbreak.c, line 12. 10: static int foo2(void); (gdb) where the function declaration is now prefixed by its source line number, followed by a colon. But without showing the declaration's file name, the line number is useless and can possibly cause severe confusion. No declaration line number was shown before. Instead, the function declaration started at the first column: (gdb) rbreak foo Breakpoint 1 at 0x40049b: file rbreak.c, line 6. static int foo1(void); Breakpoint 2 at 0x4004b1: file rbreak.c, line 12. static int foo2(void); (gdb) This old behavior is restored, fixing some FAILs in fullpath-expand.exp, realname-expand.exp, and pr10179.exp. In order to distinguish when to print location information, the meaning of print_symbol_info()'s parameter `last' is changed. Now NULL means to skip any filename or line number information. Previously NULL meant to always print the filename. gdb/ChangeLog: * symtab.c (print_symbol_info): Skip printing filename and line number when `last' is NULL. (symtab_symbol_info): Use empty string instead of NULL for first invocation of print_symbol_info. (rbreak_command): Pass NULL to `last' parameter of print_symbol_info.
