which kind of compiler optimization can be applied in this code?

compiler: linaro-aarch64-2020.09-gcc10.2-linux5.4 optimization option: -O3 CPU: Arm A53 1Ghz Hello, this is newbie. code1 is 3.1x slower than code2 - code1: 106 ms - code2: 34 ms I think...

What optimizations should be expected from a C compiler for small uPs?

My knowledge of current compiler optimization technology is very limited (or ancient). Am familiar with VHDL and Verilog for FPGA chips where extreme optimization is typical (dead code removal, code...
