Tinygo is a Go compiler for microcontrollers and WebAssembly. It also supports x86 32 bit and 64 bit Linux.
sudo apt install llvm-7-dev libclang-7-dev go get -u github.com/tinygo-org/tinygo
To compile a Linux executable:
tinygo build -o hello_tiny hello.go
The output size of a hello world program is very impressive to me:
1.1M hello 12K hello_tiny
Or run it directly:
tinygo run hello.go
