TMS320F28386S: CLA C compiler bug

Hi,

I've encountered a bug in CLA C compiler code generation.

For the C code:

float a, b, res[1];
__interrupt void testTask() {
    float p, n;
    p = a;
    n = b;
    res[0] = (p > n) ? p : -n;
}

the following assembly is generated:

        MMOV32    MR0,@a                ; [CPU_FPU] |6| 
        MMOV32    MR1,@b                ; [CPU_FPU] |9| 
        MCMPF32   MR0,MR1               ; [CPU_FPU] |9| 
        MNEGF32   MR0,MR1,LEQ           ; [CPU_FPU] |9| 
        MMOV32    @res,MR0              ; [CPU_FPU] |9| 

The problem is, that instruction MNEGF32 copies variable b to res independently of the comparison result. Effectively, the generated assembly would look like this in C, which is wrong:

    res[0] = (p > n) ? n : -n;

I tried to investigate this case further, and without res variable as an array, the generated code has branches, but is correct:

float a, b, res;

__interrupt void testTask()
{
  float p, n;
  p = a;
  n = b;
  res = (p > n) ? p : -n;
}

        MMOV32    MR0,@a                ; [CPU_FPU] |6| 
        MMOV32    MR1,@b                ; [CPU_FPU] |9| 
        MCMPF32   MR0,MR1               ; [CPU_FPU] |9| 
        MNOP      ; [CPU_FPU] 
        MNOP      ; [CPU_FPU] 
        MNOP      ; [CPU_FPU] 
        MBCNDD    $C$L1,GT              ; [CPU_FPU] |9| 
        MNOP      ; [CPU_FPU] 
        MNOP      ; [CPU_FPU] 
        MNOP      ; [CPU_FPU] 
        ; branchcc occurs ; [] |9| 
        MNEGF32   MR0,MR1               ; [CPU_FPU] |9| 
$C$L1:    
        MMOV32    @res,MR0              ; [CPU_FPU] |9| 

Although, in my application, I need to have the result in an array, so I found a workaround:

if (p > n) res[0] = p; else res[0] = -n;

For this C code, the assembly is the same as in the case above (without array).

PS. The command line invocation and compiler version:

    cl2000 -c --cla_support=cla2 --abi=eabi -mt --keep_asm -O4 --opt_for_speed=5 test.cla
