There should be no functional changes.
To improve LTO support, the
lib/bdf-plugins folder was added, with
a link to the
liblto_plugin.so library (a file copy on Windows).
This allows the use of traditional program names, like
instead of the new
arm-none-eabi-gcc-ar, without getting errors like:
arm-none-eabi-ar -r "libarm-static-lib.a" ./lib.o arm-none-eabi-ar: creating libarm-static-lib.a arm-none-eabi-ar: ./lib.o: plugin needed to handle lto object <---
The issue was reported to Arm as bug 1838049.
Partial experimental support for Python 3 was added to GDB for GNU/Linux and macOS; not yet available on Windows (24469).
Due to an omission in the build scripts, the content of the
libgcovlibrary is mostly empty; the problem was fixed starting with v8.3.1-1.2.
The original PDF documentation is available in the
Binaries for Windows, macOS and GNU/Linux are provided.
The binaries were built using the xPack Build Box (XBB), a set of build environments based on slightly older distributions, that should be compatible with most recent systems.
- GNU/Linux: all binaries were built with GCC 7.4, running in a CentOS 6 Docker container
- Windows: all binaries were built with mingw-w64 GCC 7.4, running in a CentOS 6 Docker container
- macOS: most binaries were built with GCC 7.4, running in a separate folder on macOS 10.10.5; GDB cannot be compiled with GCC, so Apple clang was used.
The binaries were testes on Windows 10 Pro 32/64-bit, Ubuntu 18 LTS 64-bit, Xubuntu 18 LTS 32-bit and macOS 10.13.
The tests consist in building and debugging some simple Eclipse projects available in the project.
Since the source code used for GCC is identical to the one used by Arm, the long and complex tests performed by Arm to validate their release were not executed again.
