Overview

Proprietary compilers made by Microchip for their lines of microcontrollers (PIC, dsPIC, etc.) They are divided into three categories: XC8, XC16, and XC32. The numbers correspond to the bit width of the CPU line, XC16 for 16-bit for example.

The 16-bit and 32-bit compilers are based on GCC, though crippled with license checks that disable optimizations for non-paid editions. However, due to the open source restrictions, they have to release the full code to the modified version and the crippling logic can be circumvented (completely legally).
