Understood. I mean: if you add up the total sizes of the original debug info sections, and the total sizes of the remaining debug info sections, what percentage of the total debug info did you remove? After all, the only point of removing debug info is to decrease the size of the files. Ian > On 03/02/2015 01:58 PM, Ian Lance Taylor wrote: >> >> On Mon, Mar 2, 2015 at 11:50 AM, Lynn A.
