Would like to know if there is any disadvantages in compiling application/device drivers with Gcc (4.3.x) and running them on OpenSoalris (128a) built with Sunstudio12. I'd assume that all debugging tools (mdb and dtrace) should work as expected. I was able to compile OpenSolaris with Gcc (SUNWgcc 3.4.3) but our sources are compiled with Gcc 4.3.3 and would like to use that or upgrade that to 4.4.4. But It is recommended that OpenSolaris (build 100 and above) should be build with SunStudio and I've not seen any update recently about ON-gcc project and not sure if the latest version of Gcc (4.4.4) will be packaged when next LIVE CD is available.
Appreciate your help.
