This is our build of AVR GCC version 7.2.0 along with AVR LIBC version 2.0.0
These are toolchains for cross-compiling code for a target microcontroller on your computer.
These are our builds of the ARM GCC compiler. This is version 7.3.1 from 2018-Q2 compiled for 32-bit Linux (x86) and ARMv7 (Raspberry Pi).
