2020-09-18Split gdb.multi/multi-target.exp into separate testcasesPedro Alves8-546/+670
gdb.multi/multi-target.exp sets up a debug environment with multiple gdbservers, multiple native processes, and multiple cores, which has proved useful for exercising a number of multi-target scenarios. But, as we add more tests to gdb.base/multi-target.exp, it is growing a bit too large (making a bit cumbersome to debug) and too slow to run (if you have glibc debug info). This commit thus splits the multi-target.exp into several testcases, one per use case. The common setup code is moved to a new multi-target.exp.tcl file that is included by all the resulting multi-target testcases. gdb/testsuite/ChangeLog: * gdb.multi/multi-target-continue.exp: New file, factored out from multi-target.exp. * gdb.multi/multi-target-info-inferiors.exp: New file, factored out from multi-target.exp. * gdb.multi/multi-target-interrupt.exp: New file, factored out from multi-target.exp. * gdb.multi/multi-target-no-resumed.exp: New file, factored out from multi-target.exp. * gdb.multi/multi-target-ping-pong-next.exp: New file, factored out from multi-target.exp. * gdb.multi/multi-target.exp.tcl: New file, factored out from multi-target.exp. * gdb.multi/multi-target.exp: Delete.

PR gdb/26598 notes that, before commit bcfe6157ca28 ("Use the linkage name if it exists"), the "skip" command would match the demangled name of a symbol, but now only matches the linkage name.

2020-09-15Avoid running one Rust test against older LLVMTom Tromey3-2/+36
LLVM 8.0 introduced some changes to let the Rust compiler emit DWARF variant parts. Before this change, the compiler would emit two types with the same name, and unfortunately gdb happens to pick the wrong one. So, this patch disables the test when using an older version of LLVM. 2020-09-15 Tom Tromey <tromey@adacore.com> PR rust/26197: * lib/rust-support.exp (rust_llvm_version): New proc. * gdb.rust/simple.exp: Check rust_llvm_version.
2020-09-15Fix exception stack unwinding for ARM Cortex-MFredrik Hederstierna2-8/+123
For Cortex-M targets using floating-point, eg the Cortex-M4F, its not possible to get any call-stack backtrace if setting a breakpoint in ISR. The exception stack unwinder for Cortex-M does not consider if floating-point registers was stacked or not, further the Cortex-M has two stack pointers: MSP (Main Stack Pointer) and PSP (Process Stack Pointer). This is not handled when GDB tries to backtrace in the exception stack unwinder. This patch fixes this, and gives a correct call-stack backtrace from breakpoints set in a handler or ISR. gdb/ChangeLog: * arm-tdep.c (arm_m_exception_cache): Try use correct stack pointer and stack frame offset when unwinding.

2020-09-12Fix GDB build in infrun.c when configured with unit tests disabledgdb-10-branchpointJoel Brobecker2-0/+7
I noticed this while testing the GDB in the context of the upcoming GDB 10 release branching, because part of the process involves setting development to False, which in turn changes the default for including unittest to false as well. As a result, without this patch, we get compilation errors in infrun.c such as: infrun.c:9219:5: error: `scoped_mock_context' was not declared in this scope This patch fixes it by bracketing the unitttest in namespace selftest with an #if GDB_SELF_TEST. gdb/ChangeLog: * infrun.c (namespace selftests): Only define #if GDB_SELF_TEST.

2020-09-12elf: Add -z unique-symbol to avoid duplicated local symbol namesH.J. Lu16-41/+406
The symbol string table in the .symtab section is optional and cosmetic. The contents of the .symtab section have no impact on run-time execution. The symbol names in the symbol string table help distinguish addresses at different locations. Add a linker option, -z unique-symbol, to avoid duplicated local symbol names in the symbol string table. This feature was well received by the livepatch maintainers. It not only solves the duplicated local symbol name problem, but also would allow livepatch to more precisely locate duplicate symbols in general for patching. bfd/ PR ld/26391 * elflink.c (elf_final_link_info): Add local_hash_table.

This adds support for the bfloat16 datatype, which can be seen as a short version of FP32, skipping the least significant 16 bits of the mantissa.

2020-09-11gas: Don't error when .debug_line already exists, unless .loc was usedMark Wielaard13-10/+369
When -g was used to generate DWARF gas would error out when a .debug_line already exists. But when a .debug_info section already exists it would simply skip generating one without warning or error. Do the same for .debug_line. It is only an error when the user explicitly uses .loc directives and also generates the .debug_line table itself. The tests are unfortunately arch specific because the line table is only generated when actual instructions have been emitted. Use i386 because that is probably the most used architecture. Before this patch the new dwarf-line-2 testcase would fail, with this patch it succeeds (and doesn't try to add its own line table). gas/ChangeLog: * as.texi (-g): Explicitly mention when .debug_info and .debug_line are generated for the DWARF format.

This behavior is desirable since it ensures that both lazy and non-lazy bindings work the same way. The problem is with --as-needed libraries, which happens with and without LTO.

gcc commit 387d0773f3 changed the D demangler, with the following commit log: libiberty: Add support for `in' and `in ref' storage classes. The storage class `in' is now a first-class citizen with its own mangle symbol, of which also permits `in ref'. Previously, `in' was an alias to `const [scope]', which is a type constructor. The mangle symbol repurposed for this is `I', which was originally used by identifier types. However, while TypeIdentifier is part of the grammar, it must be resolved to some other entity during the semantic passes, and so shouldn't appear anywhere in the mangled name. Old tests that are now no longer valid have been removed. This patch makes the same changes to the gdb testsuite as were made to the upstream gcc libiberty testsuite. gdb/testsuite/ PR 26597 * gdb.dlang/demangle.exp: Update tests as per gcc commit 387d0773f3.

Implement the following functionality: create_inferior, post_create_inferior, attach, kill, detach, mourn, join, thread_alive, resume, wait, fetch_registers, store_registers, read_memory, write_memory, request_interrupt, supports_read_auxv, read_auxv, supports_hardware_single_step, sw_breakpoint_from_kind, supports_z_point_type, insert_point, remove_point, stopped_by_sw_breakpoint, supports_qxfer_siginfo, qxfer_siginfo, supports_stopped_by_sw_breakpoint, supports_non_stop, supports_multi_process, supports_fork_events, supports_vfork_events, supports_exec_events, supports_disable_randomization, supports_qxfer_libraries_svr4, qxfer_libraries_svr4, supports_pid_to_exec_file, pid_to_exec_file, thread_name, supports_catch_syscall. The only CPU architecture supported: x86_64. Implement only support for hardware assisted single step and software breakpoint. Implement support only for regular X86 registers, thus no FPU. gdbserver/ChangeLog: * netbsd-low.cc: Add. * netbsd-low.h: Likewise. * netbsd-amd64-low.cc: Likewise. * Makefile.in (SFILES): Register "netbsd-low.cc", "netbsd-low.h", "netbsd-amd64-low.cc". * configure.srv: Add x86_64-*-netbsd*.
