* PR gdb/22824 (misleading description of new rbreak Python function in GDB 8.1 NEWS file)
* PR gdb/22849 (ctrl-c doesn't work in extended-remote)
* PR gdb/22907 ([Regression] gdbserver doesn't work with filename-only binaries)
* PR gdb/23028 (inconsistent disassemble of vcvtpd2dq)
* PR gdb/23053 (Fix -D_GLIBCXX_DEBUG gdb-add-index regression)
* PR gdb/23127 ([AArch64] GDB cannot be used for debugging software that uses high Virtual Addresses)
* PR server/23158 (gdbserver no longer functional on Windows)
* PR breakpoints/23210 ([8.1/8.2 Regression] Bogus Breakpoint address adjusted from 0xf7fe7dd3 to 0xfffffffff7fe7dd3)
GDB 8.1 includes the following changes and enhancements:
* Breakpoints on C++ functions are now set on all scopes by default
("wild" matching);
* Support for inserting breakpoints on functions marked with C++ ABI tags;
* Target floating-point arithmetic emulation during expression evaluation
(requires MPFR 3.1 or later);
* Various Python Scripting enhancements;
* Improved Rust support; in particular, Trait objects can now be inspected
when debugging Rust code;
* GDB no longer makes assumptions about the type of symbols without
debugging information to avoid producing erroneous and often confusing
results;
* The 'enable' and 'disable' commands now accept a range of breakpoint
locations;
* New 'starti' command to start the program at the first instruction;
* New 'rbreak' command to insert a number of breakpoints via a regular
expression pattern (requires Python);
* The 'ptype' command now supports printing the offset and size of
the fields in a struct;
* The 'gcore' command now supports dumping all the memory mappings
('-a' command-line option);
* New shortcuts for TUI Single-Key mode: 'i' for stepi, and 'o' for nexti;
* GDBserver enhancements:
** Support for transmitting environment variables to GDBserver;
** Support for starting inferior processes with a specified initial
working directory;
** On Unix systems, support for globbing expansion and variable
substitution of inferior command-line arguments;
* Various completion enhancements;
* The command used to compile and inject code with the 'compile' command
is now configurable;
* New '--readnever' command-line option to speed the GDB startup when
debugging information is not needed;
* Support for the following new native configurations:
** FreeBSD/aarch64 (aarch64*-*-freebsd*);
** FreeBSD/arm (arm*-*-freebsd*);
* Support for the following new targets:
** FreeBSD/aarch64 (aarch64*-*-freebsd*);
** FreeBSD/arm (arm*-*-freebsd*);
** OpenRISC ELF (or1k*-*-elf)
* Removed support for the following targets and native configurations:
** Solaris2/x86 (i?86-*-solaris2.[0-9]);
** Solaris2/sparc (sparc*-*-solaris2.[0-9]);
