Physically there are two different Stack Pointers: the Main Stack Pointer (MSP, or SP_main in some ARM documentation) is the default Stack Pointer. It is selected after reset, or when the processor is in Handler Mode. The other Stack Pointer is called the Process Stack Pointer (PSP, or ...

ARMv8-M implementation with the Main Extension and the Security Extension have two pairs of MPS/PSP Limit registers (secure and non-secure) Design Stack Pointer (SP)-limit-based protection could replace the MPU-based stack guards on ARMv8-M CPU with native SP limit checks: ...
June 19, 2023 -- The latest release of SEGGER's Embedded Studio for ARM comes with STOP technology, designed by SEGGER to reliably prevent stack overflows. With STOP enabled, the compiler adds a call to a stack limit-check routine wherever necessary, before adjusting the stack pointer. The ...

voidf(){__builtin_unwind_init();} 编译器用.cfi_*(CFI directive)标注汇编,.cfi_startproc和.cfi_endproc标识FDE区域,其他CFI directives描述CFI instructions。 一个call frame用栈上的一个地址表示。这个地址叫做Canonical Frame Address (CFA),通常是call site的stack pointer值。下面用一个例子描述CFI instr...
gcc提供了编译选项-fomit-frame-pointer和-fno-omit-frame-pointer,如果在编译时指定了-fno-omit-frame-pointer,那么就没有帧指针了,所以也就无法进行栈回溯了,默认有帧指针。 使用API进行栈回溯 在用户空间提供了回溯用的API: #include <execinfo.h>intbacktrace(void **buffer,intsize);char **backtrace_symbols...
The stack trace includes the base pointer for the stack frame, the return address, and the function names. If you use thekporkPcommands, the full parameters for each function that's called in the stack trace are displayed. The parameter list includes each parameter's data type, name, and ...

stack pointer storage to store a stack pointer, wherein a current value of the stack pointer is indicative of an extremity of the call stack associated with a most recently called subroutine which has been called during the data processing operations and has not yet returned,wherein the ...
