The whole 'shortEnums' functionality is added because of https://bugs.eclipse.org/bugs/show_bug.cgi?id=289018.|
By default, TI's Arm compiler packs enums. That can be verified by looking into the section $build.attributes, and decoding it as specified in the section 220.127.116.11 The procedure call-related attributes, in http://infocenter.arm.com/help/topic/com.arm.doc.ihi0045c/IH I0045C_ABI_addenda.pdf.
The TI Arm compiler has the option --enum_type=unpacked,int,packed, designate enum type (Default is packed for EABI). If we were passing that option for our M3 target, shortEnum would be false. I don't know if there is a good reason that we should, but the linker would certainly complain if the object files with different enum options were linked together. That means that the different shortEnum options require two different M3 targets.
