There are some good reasons for many of the non GCC compilers in
embedded systems. GCC doesn't handle very well some of the ISA's that
are used in many of the embedded systems applications.

In my experience there are a lot of ISA's designed for machine generated
code that don't map very well in the GCC (some do as well) A processor
that I have been working on for example it is essentially impossible to
write an assembler for.

GCC tools are for the most part using old compiler technology. Some of
is decades old.

There is a lot of work going on in area's that just are ineffective in
with GCC tools that are easier to deal with user other code generation
tools.

In my case a massively parallel processors, AI ISA's, ISA's for machine
generated code and various event driven processors used in automotive,
general aviation and instrumentation.
