Hi,

briefly - gcc is open source and free compiler. Diab and GHS are proprietary compilers and paid.

technical difference is that GHS, Diab and gcc uses different linker file structure and there are incompatibilities in pragma directives. You can modify WindRiver or GreenHills project to be able compile with gcc. Or you can install Windriver plugin into S32DS: HOWTO: Install Wind River compiler Eclipse plug-in into S32 Design Studio

More detail about differences you can find on GHS, WindRiver and GNU gcc web pages pages.
