airbag_fd Drop-in crash handlers for POSIX, particularly embedded Linux. Copyright 2011 Chuck Coffing <firstname.lastname@example.org>, MIT licensed https://github.com/ccoffing/airbag_fd Dumps registers, backtrace, and instruction stream to a file descriptor. Intended to be self-contained and resilient. Where possible, will detect and intelligently handle corrupt state, such as jumping through a bad pointer or a blown stack. The harvesting and reporting of the crash log is left as an exercise for the reader. Quick start: 1. Include airbag_fd.c and airbag_fd.h in your project. 2. If it doesn't build, define the appropriate DISABLE_* flag(s). 3. Call one of the airbag_init_* functions early. 4. Post-crash (perhaps in a watchdog or on next startup) harvest crash logs. Example test: $ g++ -Os -Wall -Wextra -ldl airbag_fd.c airbag_fd_test.c -o airbag_fd_test $ ./airbag_fd_test.sh x86: x86_64: mips: Should just work. arm: Optionally build your application with -mpoke-function-name.
