- Subject: Compiling expressions
This is the third newbie question I make here, but...
If I put, for example:
variable = 1 + 2;
gcc will compile the code for the CPU add one to two and put in
variable, in execution time, or will substitute and in the compiled
code the equivalent of:
variable = 3;
would be inserted?
If it evaluate expressions like this before compiling, it always is
done? Or I would need some directive to ask gcc to evaluate it for me
before compiling?
Thank you :)
