code size difference between version 4.22a and 4.23

Ramanarayanan TATA CONSULTANCY SERVICES

Hi,

I am using a Samsung chip with cortex-M3 core,when i Build the code using 4.22a version of keil the code size is aroung 498KB at optimization level 1.The same code when i build using 4.23 version with same optimization level is coming around 473Kb.Does anyone can help me telling why this difference is happening.

Thanks in advance,

Regards,
Ramanarayanan

    Also, if my understanding is correct, a build without a preceeding "clean" will use a linker feedback file which will result in further optimisation. Therefore a rebuild after a "clean" is likely to produce larger code than a subsequent rebuild without a "clean".
