Description Nathan Ridge CLA 2017-10-17 23:41:57 EDT 
CDT's current method for representing types as strings is quite inefficient. In bug 519121, for example, we were getting OOM errors due to building type-strings that were over 30 million characters long. The fix applied there is more of a workaround; it would be good to have a more systematic solution.

One idea that has been suggested is to adopt the Itanium ABI's name mangling scheme to generate string representations of types.
