From: Adrian Freihofer <[email protected]>
This series adds clang toolchain support to devtool ide-sdk. LLDB is
part of the same LLVM project as clang and is the more natural debugger
pairing for it (much like GDB pairs with gcc), so ide-sdk now picks LLDB
as the debugger whenever the recipe is built with clang, while
continuing to use GDB for gcc-built recipes as before. The series also
significantly extends oe-selftest coverage for both debugging paths
(ide=code and ide=none).
Highlights:
- Introduce a debugger back-end abstraction in ide-sdk so GDB and LLDB
can share the common ide=code/ide=none plumbing, and select LLDB
automatically when the recipe's toolchain is clang.
- Add LLDB support for the clang toolchain, for both ide=code
(lldb-server platform mode + CodeLLDB launch/task config) and ide=none
(generated shell scripts).
- Fix a handful of pre-existing ide-sdk issues found along the way:
waiting for the gdbserver port before returning, a duplicate -p flag in
_target_ssh_args, $@ getting overwritten by `set` in the
install_and_deploy script, and meson compile_commands.json generation.
- Refactor the meta-selftest cpp debugging examples into shared .inc
files with clang variants, and add real, end-to-end debug session
coverage (breakpoints in the executable, a library and a header-only
inline function) for GDB (meson) and LLDB (clang, both ide=code and
ide=none), including a recompile/redeploy cycle.
For now the debugger is selected purely based on the recipe's
TOOLCHAIN (gcc -> GDB, clang -> LLDB). Other combinations, e.g. gcc for
compiling with clang-tidy for static analysis, or support for the VSCode
clangd plugin are not covered yet but could be supported in the future
by making the debugger selection more independent from the compiler
choice.
