It is a very long time since I have used TI's ARM devices, and therefore 
its tools.  For STM, it was maybe a year or two ago.  There are many 
manufacturers of microcontrollers, and while I have used a fair number 
over the years, I don't use all the different ones all the time.  I also 
don't change development tools in existing projects.

If TI and STM have changed over to providing clang-based tools, that is 
interesting to know.  I will probably be working on a new STM32 project 
later this year.  So that's nice information to know.

It doesn't surprise me that some have moved to clang-based tools - I 
think it was inevitable.  And I think it is good to see some variety and 
competition.  But if the clang toolchains are not freely available in a 
device-independent fashion in the manner of the ARM-sponsored gcc 
toolchains, then it will be a big step backwards.  The last thing 
embedded developers want is more custom variant toolchains and vendor 
lock-in.  We used to have that - gcc let us escape from it.  A 
disadvantage of clang's license is that it lets vendors try that shit again.


So this is all very interesting, but it does not change the fact that 
gcc totally dominates for embedded development at the moment.  It does, 
however, mean the proportions may change significantly in the coming years.
