SDCC is a retargettable, optimizing ANSI C compiler suite that targets
the Intel MCS51 based microprocessors (8031, 8032, 8051, 8052, etc.),
Maxim (formerly Dallas) DS80C390 variants, Freescale (formerly Motorola)
HC08 based (hc08, s08) and Zilog Z80 based MCUs (z80, z180, gbz80,
Rabbit 2000/3000, Rabbit 3000A). Work is in progress on supporting the
Microchip PIC16 and PIC18 targets.
