[请教]MDK5.27 AC6编译是产生错误

darkness

我是V5板用户，最近在多个地方看见Eric发的MDK AC6编译速度快，所以决定试一下。
工程是使用stm32cube产生的带Freertos 的工程，默认使用AC5正常编译，无警告。
选用AC6后，出现一堆错误，看起来主要是port.c的汇编产生的。
在论坛里坛友有分享了一篇“Migrate ARM compiler 5 to ARM Compiler 6”，在第10页提到inline assembler的问题，但不知道怎么改？
请问是否可以指导一下？
感谢感谢。

要移植MDK里面带的FreeRTOS源码，他们对AC6做了支持，

例子的话，参考我这个帖子：

基于V7开发板的RTX5和FreeRTOS带CMSIS-RTOS V2封装层的模板例程下载，AC6和AC5两个版本

刚好搞这个用GCC/ARM_CM0覆盖到RVDS/ARM_CM0编译OK
