Adding a redundant assignment speeds up code when compiled without optimization (1) I find an interesting phenomenon: #include #include int main() { int p, q; clock_t s,e; s=clock(); for(int i = 1; i < 1000; i++){ for(int j = 1; j < 1000; j++){ for(int k = 1; k < 1000; k++){ p = i + j * k; q = p; //Removing this line can increase running time. } EE382N-4 Embedded Systems Architecture Main features of the ARM Instruction Set All instructions are 32 bits long. mov opcodes that put an imm8 or imm32 into a register.

Derived from the May 2019 version of the Intel® 64 and IA-32 Architectures Software Developer’s Manual. Instructions (basically identical to 32-bit x86) For gory instruction set details, read this per-instruction reference, or the full Intel PDFs: part 1 (A-M) and part 2 (N-Z). This reference is intended to be precise opcode and instruction set reference (including x86-64).
