[libcpu/arm/cortex-m33]: Fix incorrect CPU architecture in GCC context switch

2025-11-02T08:23:31Z

The context_gcc.S file was incorrectly marked as cortex-m4 in both the doxygen comment and .cpu directive, while the IAR and KEIL versions correctly specify cortex-m33. This file uses ARMv8-M specific features (PSPLIM register, TrustZone support) that are not available in Cortex-M4. Changes: - Update doxygen group from cortex-m4 to cortex-m33 - Change .cpu directive from cortex-m4 to cortex-m33

实现MPU抽象层 (#8080)

2023-10-30T12:24:55Z

- 为RT-Thread设计MPU抽象层，支持ARMV7-M，ARMV8-M架构，让用户使用MPU检测栈溢出等内存问题，实现线程内存隔离 - 在components/mp目录下提供通用的API，libcpu目录下提供各处理器架构的具体实现 - 在STM32U575 NUCLEO， STM32H75 NUCLEO开发板测试通过

[bugfix] libcpu/arm/cortex-m/context_gcc: 修复thumb指令集汇编语法错误

2021-12-09T03:22:46Z

当使用thumb指令集时，要求汇编语法中的“条件执行”要跟在IT指令后面，否则会编译不通过。报错如下：Error: thumb conditional instruction should be in IT block -- `moveq r4,#0x01' 虽然可以通过指定"-Wa,-mimplicit-it=thumb"选项来告诉编译器识别隐式的IT指令，但是能在代码里面直接加上IT指令的话更好。 thumb指令集“条件执行”arm官网文档： https://developer.arm.com/documentation/dui0473/m/condition-codes/conditional-execution-in-thumb-state 参考论坛帖子： https://club.rt-thread.org/ask/question/433887.html https://club.rt-thread.org/ask/question/4188.html Signed-off-by: Mingrui Ren
