Arm® Cortex®-M3 has two privileged levels (Privilege/Non-privilege) and two operation modes (Thread/Handler). For embedded usage, a basic configuration with only privileged level or a configuration to switch between Privilege and Non-privilege can

Summary minor update to boot_stage_puts, save/restore LR out of the loop. pointer to stack frame must be aligned. Impact No. Testing Internal project and qemu.
In this example, a function stores the return address onto the stack and defines a local variable that is defined as a sequence of characters. The buffer is allocated by “moving” the Stack Pointer (SP) up by the number of bytes the buffer requires. The write direction is “down” (if...
Code 1: Representation of a register in the model ARM. Creating an array ofRegDatastructures then allows the register file to be emulated. The Program Counter (PC) and Stack Pointer (SP) can be added to the register file to give the model a basis to interpret code. ...
2.3 arm linux内核可通过gcc plugin支持 per-cpu canary: arm linux kernel 通过一个gcc plugin(arm_ssp_per_task_plugin)基于per-cpu 寄存器sp实现了 per-task canary功能 四、编译器中全局canary的实现 这里以aarch64平台,gcc + -fstack-protector-strong为例,其实现逻辑如下(源码分析见备注2): ...
R13, stack pointer (SP) R13 is the Stack Pointer. It is used for accessing the stack memory via PUSH and POP operations. 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 aft...
