[Curiosity, not an objection.] It appears that most likely all FreeBSD platforms get the gdb setting by default . . . armv7: # cc -v main.c FreeBSD clang version 17.0.6 (https://github.com/llvm/llvm-project.git = llvmorg-17.0.6-0-g6009708b4367) Target: armv7-unknown-freebsd15.0-gnueabihf . . . -debugger-tuning=3Dgdb . . . -x c main.c . . . aarch64: # cc -v main.c FreeBSD clang version 17.0.6 (https://github.com/llvm/llvm-project.git = llvmorg-17.0.6-0-g6009708b4367) Target: aarch64-unknown-freebsd15.0 . . . -debugger-tuning=3Dgdb . . . -x c main.c . . . amd64: # cc -v main.c FreeBSD clang version 17.0.6 (https://github.com/llvm/llvm-project.git = llvmorg-17.0.6-0-g6009708b4367) Target: x86_64-unknown-freebsd15.0 . . . -debugger-tuning=3Dgdb . . . -x c main.c FYI: QUOTE of = https://clang.llvm.org/docs/UsersManual.html#controlling-debugger-tuning Controlling Debugger =E2=80=9CTuning=E2=80=9D While Clang generally emits standard DWARF debug info = (http://dwarfstd.org), different debuggers may know how to take = advantage of different specific DWARF features.
