为什么不用ARM DS-5开发Cortex-M系列？

今天刚看到ARM Compiler 6.02的发布消息，但还未添加到DS-5中，不过可以通过手动的方式加入。

根据Stefano Cadario的blog看来，6.02支持了新的C++11和C++14，可以获取最新的C++特性，进而完成更多的功能。还对Cortex-M的性能进行了优化。

其中提到：

“

Embedded ARM microcontrollers have been less of a focus for the LLVM community and ARM is now filling the gaps by making ARM Compiler 6 a toolchain able to build efficient code across all range of ARM processors, from the smallest Cortex-M0+ to the latest Cortex-A72 64-bit processor.

”

也就是ARM还是会整合整个产品线的开发，即ARM Compiler 6只是先对Cortex-A系列产品进行了支持、优化，但随后会更新到Cortex-M，毕竟A系列才是大头。还说到：

“

ARM engineers have focused on Cortex-M processors and we are now confident enough to change the support level for Cortex-M family cores from alpha to beta: this means that the code generated for the ARMv7-M and ARMv6-M architectures has reached a good quality level and has been sufficiently tested by ARM (but still work to do hence the beta support moniker). We expect to complete support for ARMv7-M and ARMv6-M in the next release of ARM Compiler at the end of this year.

”

ARM的工程师开始专注于Cotex-M系列产品，并对其进行优化，毕竟目前的版本还是刚从alpha到beta，预计今年年底的release版本会全面支持ARMv7-M和ARMv6-M架构的产品，即Cortex-M0至Cortex-M7。

由此看来不论是MDK-ARM还是DS-5，,如果都升级到ARM Compiler 6后，都会对Cortex-M全面的支持。目前MDK-ARM只支持ARM Compiler 5。

根据ARM Compiler 6.02的releasenotes看来，ARMv7-M, ARMv6-M架构的产品只能使用ARM Compiler 5：

那么这样的话就看DS-5 IDE是否届时全面替代MDK-ARM了。
