code size difference between version 4.22a and 4.23

Ramanarayanan TATA CONSULTANCY SERVICES over 13 years ago

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

My problem was because the compiler version is same only Keil version was differend,so as per my understanding same compiler version should give same code at same optimization level.
the linker does some optimization as well e.g. combining function tails from different modules.
