Version 0.5.0 has many big and small improvements. The headline changes include support for the Go standard library 1.12 in addition to the existing Go 1.11 support and a switch to LLVM 8 which improves WebAssembly support. Other notable changes are support for the stm32f4discovery and dropping the dependency on the GNU toolchain for ARM microcontrollers.

  • compiler driver
    • use wasm-ld instead of wasm-ld-8 on macOS
    • drop dependency on llvm-ar
    • fix linker script includes when running outside TINYGOROOT
  • compiler
    • switch to LLVM 8
    • add support for the Go 1.12 standard library (Go 1.11 is still supported)
    • work around lack of escape analysis due to nil checks
    • implement casting named structs and pointers to them
    • fix int casting to use the source signedness
    • fix some bugs around make([]T, …) with uncommon index types
    • some other optimizations
    • support interface asserts in interp for "math/rand" support
    • resolve all func value targets at compile time (wasm-only at the moment)
  • cgo
    • improve diagnostics
    • implement C struct, union, and arrays
    • fix CGo-related crash in libclang
    • implement C.struct_ types
  • targets
    • all baremetal: pretend to be linux/arm instead of js/wasm
    • avr: improve uintptr support
    • cortexm: implement memmove intrinsic generated by LLVM
    • cortexm: use the lld linker instead of arm-none-eabi-ld
    • darwin: use custom syscall package that links to libSystem.dylib
    • microbit: add blink example
    • samd21: support I2C1
    • samd21: machine/atsamd21: correct pad/pin handling when using both UART
      and USBCDC interfaces at same time
    • stm32f4discovery: add support for this board
    • wasm: support async func values
    • wasm: improve documentation and add extra example
