我希望将 AN78175 的安全软件程序库集成到我正在开发的 PSoC5LP 项目中，该项目需要对 RAM/闪存/CPU 进行更密集的自测试。 我的问题是在尝试组装 SelfTest_CPU_s.s 时出现的。 装配源文件。 出于某种原因，它似乎无法识别表示注释的分号字符？
以下是该文件的完整内容：

我知道这个代码已经很旧了（好像是 2012 年的）。 是否存在某些不兼容性？ 我注意到它在顶部注释块中提到了"RealView Compiler" 。 这可能是某个不再使用的传统编译器/汇编器吗？ 无论如何，ARM GNU GCC 是否不将分号视为注释？ 我是否应该删除这个源文件，然后使用写在 SelfTest_CPU_asm.c 中的 CPU_PSoC_Asm() 函数？ 文件？ 我相信，它所做的事情本质上是一样的：
__attribute__((naked)) uint8 CPU_PSoC_Asm(void) /* declaration of function if PSoC 5 GCC compiler */ { /* Disable global interrupts */ CyGlobalIntDisable; __ASM volatile ( " PUSH {R1-R12, LR} nt" CPU_REGISTER_TEST("R0") #if (ERROR_IN_CPU_REGISTERS) CPU_REGISTER_TEST_ERROR("R1") #else CPU_REGISTER_TEST("R1") #endif CPU_REGISTER_TEST("R2") CPU_REGISTER_TEST("R3") CPU_REGISTER_TEST("R4") CPU_REGISTER_TEST("R5") CPU_REGISTER_TEST("R6") CPU_REGISTER_TEST("R7") CPU_REGISTER_TEST("R8") CPU_REGISTER_TEST("R9") CPU_REGISTER_TEST("R10") CPU_REGISTER_TEST("R11") CPU_REGISTER_TEST("R12") CPU_REGISTER_TEST("LR") /* Test SP register */ /* Note: SP ignores writes to the lower two bits, so they are intentionally set to 0 */ /* Save SP to R0 */ " MOV R0, SP nt" /* Load SP with 0xAAAAAAA8 */ " LDR R1, =0xAAAAAAA8 nt" " MOV SP, R1 nt" " CMP SP, R1 nt" /* Restore SP and return failure */ " IT NE nt" " MOVNE SP, R0 nt" " BNE __test_asm_fail nt" /* Load SP with 0x55555554 */ " LDR R1, =0x55555554 nt" " MOV SP, R1 nt" " CMP SP, R1 nt" " IT NE nt" " MOVNE SP, R0 nt" " BNE __test_asm_fail nt" " MOV SP, R0 nt" /* Return success */ " MOV R0, #0 nt" " POP {R1-R12, LR} nt" " BX LR nt" /* Return failure */ "__test_asm_fail: nt" " MOV R0, 0x00000001 nt" " POP {R1-R12, LR} nt" " BX LR nt"); /* Enable global interrupts */ CyGlobalIntEnable; /* end of assembler code for PSoC 5 */ }
我注意到 CyGlobalIntDisable/CyGlobalIntEnable 也会出错："，不支持裸函数中的非 ASM 语句" 。 是否可以分别用" CPSID i nt" 和" CPSIE i nt" 来代替？
我使用的是 PSoC Creator 4.3，编译器是 ARM GCC 5.4-2016-q2-update。
