Hi Experts,
What is the key difference between if/else and swtich case statements ?
How the modern ARM GCC compilers handles it ?
If you really want to know what the compiler does about them you should start looking up things like static single assignment (SSA) and phi functions. Compilers can be a bit tricky in some areas but the source for how things like conditionals are handled and optimized for each particular architecture is really quite readable and almost user friendly nowadays.
