Want to try out stable GCC 7 on your LPC/Kinetis?

EDIT: Stable GCC 7.1.0 is already released - see my reply below for details! 

If you're very impatient waiting for the full GCC 7.1.0 release (expected this month), there's absolutely no need to wait any longer (; You can try experimental GCC 7 version with your LPC (or Kinetis) microcontroller right now (;

The script is able to produce a working toolchain for Linux. It is also possible to cross-compile a toolchain for Windows (32-bit or 64-bit) - either in Linux or in "Bash on Ubuntu on Windows" (I've heard it can be done, but the process is painfully slow - who would expect that? (; ).

I've tested that toolchain briefly and it appears to work fine (;

Thank you for this information and the 'history background' there. I wasn't aware of the problems with Cortex-M4 although I noticed some problems, when building my toolchains for my controllers.
