I specifically am not using the stdout printf function. (in fact stdout is not included at all). Yet, I noticed in the map file that _printfi.obj shows up under /ccsv7/tools/compiler/ti-cgt-c2000_16.9.1.LTS/lib/rts2800_fpu32.lib. It's taking up 3094 bytes, which isn't a small fraction of the total used.
I'm not sure, however, how to track down what could be causing this.
