369 43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	10	The purpose of a compiler is to transform a program, a human
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	11	can write, into code the machine can run as fast as possible.
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	12	The fastest code would be machine code the CPU can run
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	13	directly, but it is often enough to improve the speed of a
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	14	program by just targeting a virtual machine. This produces not
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	15	the fastest possible code, but code that is fast enough and
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	16	has the advantage that the virtual machine care of things a
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	17	compiler would normally need to take care of (like explicit
43c0ed473720 updated Christian Urban <christian dot urban at kcl dot ac dot uk> parents: 327 diff changeset	18	memory management).
