The arm-none-eabi-gdb binary in the windows 12.3.rel1 release is built with a debug configuration. The binary file is 263MB (contains symbols) whereas previous versions were around 6MB. I'm hoping ARM will see this and fix it for the next release :)
Thank you for your reply.
If it was just a case of symbols in the binaries, I would not have raised it. This is clearly a defect in your build/deployment process. It only effects arm-none-eabi-gdb.exe. All other binaries have been built correctly i.e. using a 'release' configuration (no symbols and compiler optimizations enabled).
The main problem isn't the symbols in the gdb binary, it is the speed. Since it was built with a debug configuration, it was not compiled with compiler optimizations enabled. It runs considerably slower than the previous versions (gcc 10). E.g when reading a large ELF file, it was normally instantaneous, but now it is taking over 20 seconds. This has been raised before - see
You can easily test it yourself. Compare the time arm-none-eabi-gdb.exe v10 and v12.3 take to read a large ELF file. The later one takes magnitudes longer. It is not because the functionality has changed, but because it wasn't built with compiler optimizations.
