Compiler/MSP430-GCC-OPENSOURCE: Warning: a NOP might be needed here because of successive changes in interrupt state

EE LL

Part Number: MSP430-GCC-OPENSOURCE
Other Parts Discussed in Thread: SIMPLICITI

Tool/software: TI C/C++ Compiler

This issue was reported more than a year ago (https://e2e.ti.com/support/development_tools/compiler/f/343/t/502857) and TI offered to notify the developer about it.

However it is still present even in the latest MSP430-GCC release (5.1.1.0) - I also tried several previous releases and they all have it.

The Warnings are very annoying and confusing inside a development team environment. I use the simpliciti stack which enables/disables interrupts in lots of places hence generates a huge amount of these warnings.

Also note that the switch -mY which is supposed to take care of it is not accepted by MSP430-elf-gcc.exe. The switch causes the compiler to stop so can't be used..

Please have Somnium take a look and resolve it asap.

    I apologize for the trouble.

    Since that bug was first reported, we started filing and tracking bugs on MSP430 GCC tools in the SDOWP system.  For this issue, I filed MSPGCC-5.  You are welcome to follow it with the SDOWP link below in my signature.

    As can be seen on the release announcement for version 5.1.1.0 ...

    Somnium is no longer providing mspgcc releases for TI. This will be the final mspgcc release for the 6.x branch. TI is investigating options.

    For this reason, I am unable to say when this bug will be addressed.

    Thanks and regards,
