CCS/TMS320F28379D: CLA abs() fabs() disassembly

Tool/software: Code Composer Studio

Hi team 

I am using TMS320F28379D. I found that 

But it shows the following when i debug 28379D with CCS and use View--> disassembly

283         float F_SetPoint = -1.2;
00bca0:   2842999A    MOV          *-SP[2], #0x999a
00bca2:   2841BF99    MOV          *-SP[1], #0xbf99
287         TempSetPoint  = fabs(F_SetPoint);
00bca4:   E2AF0042    MOV32        R0H, *-SP[2], UNCF
00bca6:   E6950000    ABSF32       R0H, R0H
00bca8:   E68C0000    F32TOI16     R0H, R0H
00bcaa:   7700        NOP          
00bcab:   E2130043    MOV16        *-SP[3], R0H

Please tell me why.
