This is a C compiler and related tools for developing firmware for TI/Chipcon RF System on Chip (SOC) parts based on the 8051 processing core. These include at least the CC1110, CC1111, CC2510, and CC2511, CC2530, CC2531, CC2533, CC2543, and CC2544.

This package started as a fork of Debian SDCC 2.9.0-5, motivated both as a workaround for increases in the size of 8051 code generated by later versions of SDCC that cause AltOS to fail to build successfully, and a desire to incorporate support for source-level debugging on real hardware.
