AM4372: Output code of compiler by while()'s conditional statement .

Hi all,

I confirmed that different asm files are output with the following two codes,.

(1) while(*PRCM_CM_IDLEST_DPLL_MPU & 0x0100 == 0x0100);

(2) while((*PRCM_CM_IDLEST_DPLL_MPU & 0x0100) == 0x0100);

In case of the asm code of (1), the code will check 0x001 instead of 0x100, so the program will not work properly.

• Why is there a difference in the output code?
• Is this a compiler bug?
• Do I always need to write code in the way of (2)?

I tried it with the following compiler.

• TI v16.9.6.LTS
• TI v18.9.0.LTS

Best regards,
Sasaki
