TheSmall Device C Compiler (SDCC ) is afree-software , partiallyretargetable [ 1] C compiler for 8-bitmicrocontrollers . It is distributed under theGNU General Public License . The package also contains anassembler ,linker ,simulator anddebugger . SDCC is a popular open-source C compiler for microcontrollers compatible withIntel 8051/MCS-51 .[ 2] [ 3] [ 4]
Sources, documentation, and binaries are available for Linux (32-bit and 64-bit), macOS (PPC and 64-bit), and Windows (32-bit and 64-bit).

Obsolete:
AVR microcontrollers used to be a supported target, but was made obsolete by avr-gcc in 2010 (SDCC 3.0.0).Z88DK - C compiler for Z80-based systemscc65 - C compiler for 6502/65C02 systems^ Rainer Leupers, Peter Marwedel: "Retargetable Compiler Technology for Embedded Systems: Tools and Applications", page 126.
