      Forum post user reported less efficient assembly for CLA with newer compiler version (280049c project：TI v20.2.1.LTS use opt =0) as compared to older version(28035 project： TI v6.4.2 use opt=0). See this:

      Attaching the CCS project (Will need to install and link C2000Ware 3.04 or greater to build code).

      Also attaching the preporcessed file generated using -O off and -mf 2.

      The user's test case file has been attached here. [^cla_ex4_pwm_control_cla.pp]
