AC6下编译NXP S32K146报错

[arcrong]

最近在使用S32K146芯片，移植过程遇到些问题。开发环境：KEILV5.36 + AC6。 1. 需要自行定义__CLANG_ARM这个宏？ S32K146仅支持AC6编译器。但从AC6的用户手册上查不到有预定义__CLANG_ARM这个宏，而是定义了__GNUC__这个宏。AC6本身是兼容GCC语法的。 我不太清楚这个宏是从哪来的？是否需要自行定义？

2. 自行添加__CLANG_ARM后，编译报错，这个需要怎么改动？ 我的修改： /* C stack block name, default is STACK */ #define CMB_CSTACK_BLOCK_NAME ARM_LIB_STACK

/* code section name, default is ER_IROM1 */ #define CMB_CODE_SECTION_NAME m_text 报错： .\app.axf: Error: L6218E: Undefined symbol Image$$m_text$$Limit (referred from cm_backtrace.o).
