The Small Device C Compiler ( SDCC ) is an open source C - cross compiler for microcontroller . In addition to the compiler, the software suite includes a linker , assembler , simulator and debugger . Its design is designed for adaptation to other 8-bit target systems ( retargetable ). The software is under the GNU General Public License .
SDCC was used to port the real-time operating system of the FreeRTOS project to the 8051 -based microcontroller series from Silicon Laboratories .
Supported target architectures
- Intel 8051 and its variants
- Zilog Z80 and binary compatible variants.
- Zilog Z180

Optimizations
Some of the architectures supported by SDCC differ significantly from other common ones, which is why SDCC has significantly different optimizations compared to other compilers such as GCC and LLVM . For example, most of the target architectures are CISC with a small number of registers. For most target architectures, SDCC uses an optimal register allocator based on tree decomposition , the runtime of which is exponential in the number of registers. The register allocation is done byte by byte (so far only fully implemented for STM8).
