From: Simon Glass <simon.glass@canonical.com> In some cases the backtrace contains useful information, such as whether a particular function was called earlier in the stack. This series provides a very simple backtrace library, along with some sandbox-specific functions to allow it to work. It is designed such that another arch could implement it. A new 'backtrace' command provides access to the backtrace. Simon Glass (10): claude: Tell it about my crosfw script being silent backtrace: Add a library to access the backtrace CI: Disable backtrace for the trace test backtrace: sandbox: Add support for obtaining symbols backtrace: sandbox: Link with libbacktraces backtrace: sandbox: Add -rdynamic to export symbols backtrace: Add a test backtrace: Add a command backtrace: doc: Mention the feature backtrace: Strip the source tree prefix from filenames .gitlab-ci.yml | 2 +- CLAUDE.md | 1 + arch/sandbox/config.mk | 13 +++- arch/sandbox/cpu/Makefile | 7 +- arch/sandbox/cpu/backtrace.c | 122 +++++++++++++++++++++++++++++++++++ arch/sandbox/lib/Makefile | 1 + arch/sandbox/lib/backtrace.c | 71 ++++++++++++++++++++ cmd/Kconfig | 8 +++ cmd/Makefile | 1 + cmd/backtrace.c | 30 +++++++++ configs/sandbox_defconfig | 1 + doc/arch/sandbox/sandbox.rst | 17 +++++ doc/usage/cmd/backtrace.rst | 51 +++++++++++++++ doc/usage/index.rst | 1 + examples/rust/build.rs | 3 + examples/ulib/config.mk | 2 +- include/backtrace.h | 72 +++++++++++++++++++++ include/os.h | 34 ++++++++++ lib/Kconfig | 8 +++ lib/Makefile | 2 + lib/backtrace.c | 55 ++++++++++++++++ test/cmd/Makefile | 1 + test/cmd/backtrace.c | 27 ++++++++ test/lib/Makefile | 1 + test/lib/backtrace.c | 47 ++++++++++++++ 25 files changed, 574 insertions(+), 4 deletions(-) create mode 100644 arch/sandbox/cpu/backtrace.c create mode 100644 arch/sandbox/lib/backtrace.c create mode 100644 cmd/backtrace.c create mode 100644 doc/usage/cmd/backtrace.rst create mode 100644 include/backtrace.h create mode 100644 lib/backtrace.c create mode 100644 test/cmd/backtrace.c create mode 100644 test/lib/backtrace.c -- 2.43.0 base-commit: 6d3cb76fe2af7453ed5bfeaacbbaedb0be087e03 branch: mal
