UBSan (Undefined Behavior Sanitizer) is a tool implemented using compiler instrumentation at runtime that allows checking for statements whose output is not deterministic or defined by the C standard. Compiling and running OpenSBI with UBSan instrumentation will print a message in the console if any sentence performs such an action. Support involves two main components: 1. The UBSan implementation hooks (derived from NetBSD), used by the compiler to handle the check output. 2. A test suite integrated with the SBI unit test framework to verify correct operation at runtime. Usage: make UBSAN=y PLATFORM=generic ... The test suite is built when both UBSAN=y and CONFIG_SBIUNIT=y are enabled. When UBSan is enabled, FW_PAYLOAD_OFFSET may need to be increased due to the size increase added by the instrumentation. A value of 0x400000 has been tested. UBSan adds runtime overhead and is intended for development builds only, not for production. Note: This patch marks __stack_chk_guard in sbi_init.c as a weak symbol to prevent multiple definition errors at compile time with UBSan instrumentation enabled. This resolves the conflict between the .globl definitions in sbi_init.c and test_head.S.
