I've no experience with that device at all, but from experience with
other toolchains provided by TI over the years, watch out for zero
initialisation of variables in the bss.

 For the cortex M4, I'd avoid using TI's toolchain if at all possible.
Download a copy of GCC from ARM.
 The general rule I've found to be true for the past 40 years is that
software/tools supplied by silicon vendors is crap.
 

Some vendor-supplied toolchains are not bad, but some are definitely subpar - and often many years behind the versions you get from manufacturer independent suppliers (like ARM's build of a gcc toolchain, or commercial gcc toolchains).  The biggest problem with microcontroller manufacturer's tools is usually the SDK's that are frequently horrible in all sorts of ways.
But I agree with your advice - where possible, use ARM's gcc toolchain build for ARM development.  And make sure your project build is independent of any IDE, whether it is from the vendor or independent. IDE's are great for coding, and vendor-supplied IDE's can give good debugging tools, but you want the project build itself to be independent.
