[MPC5777C] New compiler warning when changing versions

[darq]

Hello,

We have got some new warning during compilation of software when changing compiler version from 1607 to 1705.

The warning states:
NXP/PowerPC/platform/devices/MPC5777C/startup/gcc/startup_MPC5777C.S:503: Warning: invalid register expression
NXP/PowerPC/platform/devices/MPC5777C/startup/gcc/startup_MPC5777C.S:504: Warning: invalid register expression

The code mentioned in a warning message is as follows:

This part of the code is directly copied from NXP documentation AN5191 "MPC5777C Software Initialization and Optimization". Why is this warning showing all of a sudden and how to remove this warning in a proper way?

Best regards

I suppose it is only warning message, the assembler code is possible to compile correctly. Is it so?

Hello,

Theoretically yes, but there is a company policy of no errors or warnings for software builds. It would be a great help if there was some way to remove it.

Best regards

I have checked version of compiler I have on my PC and it is 1607. S32DS says all components are up to date. Our code has been tested with version 1607.

If you have installed compiler at you own, we cannot help as it is open-source compiler.

Hello,

This build version has been taken from NXP website:

Best regards

I see.

However anyway this is standalone compiler and S32DS as well as SDK codes has been tested with 1607.

However I can report this issue.
