## JIT
Just-in-Time
-   Compilation during execution
	-   At run time
-   Bytecode translation to machine code for execution
-   Combination of AOT compilation and interpretation
	-   Speed of compiled code
	-   Flexibility of interpretation
	-   Overhead of an interpreter
	-   Overhead of compiling
		-   As well as interpreting
-   Dynamic compilation
-   Adaptive optimization
	-   Dynamic recompilation
	-   Microarchitecture-specific speedups 
		- [ISA](ISA.md)

## AOT
Ahead-of-Time
-   Compile higher-level language or intermediate representation to machine code
	-   Runs natively
-   Machine-optimized code

## GCC
-   Standard compiler for GNU projects and Linux
-   Parse source code to produce abstract syntax tree

## LLVM
-   Compiler infrastructure
-   Develop language front ends for ISAs
-   Apple sponsored
