[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
