GDB 8.3 includes the following changes and enhancements:
* Support for new native configurations (also available as a target configuration):
- RISC-V GNU/Linux (riscv*-*-linux*)
- RISC-V FreeBSD (riscv*-*-freebsd*)
* Support for new target configurations:
- CSKY ELF (csky*-*-elf)
- CSKY GNU/Linux (csky*-*-linux)
- NXP S12Z ELF (s12z-*-elf)
- OpenRISC GNU/Linux (or1k*-*-linux*)
* Native Windows debugging is only supported on Windows XP or later.
* The Python API in GDB now requires Python 2.6 or later.
* GDB now supports terminal styling for the CLI and TUI.
Source highlighting is also supported by building GDB with GNU
Highlight.
* Experimental support for compilation and injection of C++ source
code into the inferior (requires GCC 7.1 or higher, built with
libcp1.so).
* GDB and GDBserver now support IPv6 connections.
* Target description support on RISC-V targets.
* Various enhancements to several commands:
- "frame", "select-frame" and "info frame" commands
- "info functions", "info types", "info variables"
- "info thread"
- "info proc"
- System call alias catchpoint support on FreeBSD
- "target remote" support for Unix Domain sockets.
* Support for displaying all files opened by a process
* DWARF index cache: GDB can now automatically save indices of DWARF
symbols on disk to speed up further loading of the same binaries.
* Various GDB/MI enhancements.
* GDBserver on PowerPC GNU/Linux now supports access to the PPR,
DSCR, TAR, EBB/PMU, and HTM registers.
* Ada task switching support when debugging programs built with
the Ravenscar profile added to aarch64-elf.
* GDB in batch mode now exits with status 1 if the last executed
command failed.
* Support for building GDB with GCC's Undefined Behavior Sanitizer.

This fixes compilation of gdb on arm64.
The kernel defines "struct sigcontext" in asm/sigcontext.h and musl libc
defines it in signal.h, which collides.
Kernel 4.14 misses the definitions of struct user_sve_header so we still
have to use the aarch64-sve-linux-sigcontext.h header file which also
provides that and make sure aarch64-sve-linux-sigcontext.h does not
provide the same headers as the kernel or musl.
Fixes: FS#2040
