Compiler/MSP430FR5969: TI Compiler v18 and v19 not working with MSP430FR5969 - Redefinition of #__disable_interrupts()

Stephen Cool

Part Number: MSP430FR5969

Tool/software: TI C/C++ Compiler

Currently getting compiler error after TI Compiler Update from version v15.12.7 to v18.12.4.

: #48 incompatible redefinition of macro "_disable_interrupts" (declared at line 129 of "C:/ti/ccs930/ccs/tools/compiler/ti-cgt-msp430_19.6.0.STS/include/intrinsics.h")

For some reason, I don't get this error with v16.9.11. I do get this error with v18 and v19 compilers.

It looks like msp430fr5969.h is defining __disable_interrupts in intrinsics.h header file and also v18.12.4 is including in _atomic.h file

Looks like incompatibility with older MSP430 chips and newer compilers. Someone please advise

Hello,

I know that the msp430fr5969.h header file has #include <intrinsics.h>.

I don't know where #include <atomic.h> is coming from. Did you explicitly add this in one of your files?

You can always manipulate the GIE bit directly:

__bis_SR_register(GIE); // enables interrupts

__bic_SR_register(GIE); // disable interrupts.

I did not include anywhere. This problem is purely TI distributed code. Like I said, this problem doesn't exist on v15 and v16 compilers. It occurred when I tried upgrading to v18 and v19 compilers.

atomic.h is being included by the compiler. I can see a build file including it with the following path: C:/ti/ccs930/ccs/tools/compiler/ti-cgt-msp430_19.6.0.STS/include/_atomic.

I do not want to manipulate the GIE directly. __disable_interrupts() is much clearer.

This is a bug in TI's compiler

Yes, your right, it should be the problem in new v18/ v19 compiler. I will report this issue to CCS team.

Okay. Do they have anticipated release date?
