Compiler: MISRA 12.6 violation incorrectly assigned

Other Parts Discussed in Thread: C2000WARE

Tool/software: TI C/C++ Compiler

c2000 compiler 18.1.1.LTS and C2000Ware_1_00_04_00

Using blinky example for CPU1 for F2837xD control card

In F2837xD_SysCtrl.c

If I have MISRA checking enabled for only section 12.6 in this SysCtrl file, I get some lines that violate 12.6.  Some are actually violating 12.6, and some I think are incorrectly interpreted as violating 12.6.

Specifically,

// line 630
ClkCfgRegs.SYSCLKDIVSEL.bit.PLLSYSCLKDIV = divsel;
// line 851
WdRegs.WDCR.all = WDCR;
// line 882
ClkCfgRegs.SYSCLKDIVSEL.bit.PLLSYSCLKDIV = divsel;

#1483-D (MISRA-C:2004 12.6/A) Expressions that are effectively Boolean should not be used in operations with expressions that are not effectively Boolean

where it seems nothing boolean is going on here.

    Thank you for reporting the problem, and sending in the relevant details.  I can reproduce those diagnostics, and others like them.  The entry CODEGEN-4617 is already filed in the SDOWP system about this issue.  I added your test case to it.  You are welcome to follow it with the SDOWP link below in my signature.

    Thanks and regards,
