Currently "upcc -E" must launch clang-upc (or clang) because clang-upc2c does not support the "-E" flag. Unless there is a fundamental problem with doing so, adding support for "-E" would be desirable to make clang-upc2c completely stand-alone (e.g. built after installing clang).
This is categorized as an enhancement because end-user use of "-E" is uncommon, and because one does not currently build clang-upc2c w/o a corresponding clang.
