Compiler Pipeline

What happens in the background when we enter tcc main.c -o out? - To find out, we need to explore the stages that a compiler goes trough.

1. (optional) preprocessor

takes in code, parses it, includes files, parses them, includes files, expands macros, ... Can also happen after (or during) main lexing (which is waaay smarter)

2. lexer (aka tokenizer)

Tokenizes your code example: printf("Hello, %s\n", getName()); -> printf ( "Hello, %s\n" , getName, ( ) ) ;

# 6502 16-bit vector extension
(The opcodes of this extension are choosen with the w65c02 in mind)
This extension is designed to speed up 2-D vector and memory operations.

## Registers
This extension adds one single SIMD register:

### V
A 16-bit general purpose register.

# 6502 32-bit vector extension
This extension is based on [16-bit vector extension)[https://gist.github.com/alex-s168/4affe0004397688aeb88fbd6e194bdc0].
All instructions and registers from the "old" extension are assumed to be present here.

## Registers
This extension adds one single SIMD register:

### W
A 32-bit single instruction multiple data (SIMD) register.
The low word of this register overlaps with the full `V` reigster.

/*
Example usage:
```
char *url;
char *params[2] = { "name", "mail" };
urlGETAll(url, params, 2);
printf("name: %s\n", params[0]);
printf("mail: %s\n", params[1]);
```
