## Summary On Linux at least, the `-g` option of `fpc` defaults to generating debug information in the DWARF2 format. I tested on aarch64-linux and x86_64-linux and that was the case. This is good. However, on armv8l-linux (that is, 32-bit Arm), it defaults to stabs. This was [noticed](https://lists.linaro.org/archives/list/linaro-toolchain@lists.linaro.org/thread/4GDCZ5ERHUVWSFUS6IKT5UKWA3TYP6LI/) because GDB just [removed](https://inbox.sourceware.org/gdb-patches/20251020152853.28195-1-guinevere@redhat.com/) support for the stabs debug format, and the GDB tests for Pascal started to fail on our CI for armv8l-linux. ## System Information Tested on Ubuntu 24.04 and 25.04 systems, both of which have fpc 3.2.2 installed. ## Steps to reproduce Assuming `hello.pas` is a simple hello world program: 1. `fpc -o hello -g hello.pas` 2. `readelf -w hello` ## What is the current bug behavior? On aarch64-linux and x86_64-linux, the last command outputs the DWARF debug info in the hello binary. On armv8l-linux, the output is empty because there is no DWARF debug info, only stabs. ## What is the expected (correct) behavior? There should be DWARF debug info when using the `-g` option in armv8l-systems.
