Status of GNU tool chain for PowerPC

Our FAE left your company without out any words of warning, so I post this here.

Here is the list of open PRs for GNU Binutils and GCC as discussed on the embedded world:

https://sourceware.org/bugzilla/show_bug.cgi?id=19554

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69617

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69618

Please note that I put Edmar Wienskoski <edmar@freescale.com> on CC. There is no NXP contact in the Binutils/GCC MAINTAINERS file and the Freescale person gave no response. This basically shows again that the Freescale/NXP PowerPC GNU tool chain is unmaintained.

Hello,

This question still has no answers after more than a year.

What is the state of the patches found in PowerPC Linux SDK 1703, with regards to gcc 4.9.3 ? Are the patches included upstream?

Is it safe to use upstream gcc ?

In SDK 1703 meta-freescale, I have the following patches:

I guess these bugs are also present in your SDK. In case these bugs are not present in your SDK, then why didn't you fix them in the FSF upstream version?

Who maintains the NXP/PowerPC in the FSF upstream (Binutils/GCC) after the NXP take over of Freescale? NXP should select a maintainer and propose them to the FSF steering committee.

Hello Sebastian Huber,

So far we are still using binutils 2.25 and GCC 4.9.3, the above PRs are about binutils 2.27 and GCC 6.0. I have already reported these defects to Toolchain and Linux SDK production team, will fix them in the future Linux SDK release.


Have a great day,
Yiping
