New Revision: 63093
URL: http://llvm.org/viewvc/llvm-project?rev=63093&view=rev
Log:
make -print-stats print stats about the amount of the SLoc
address space we used up. Some interesting data:
For c99-intconst-1.c:
6912762 SLocEntry's allocated, 25592386B of Sloc address space used.
For cocoa.h:
26469 SLocEntry's allocated, 10278752B of Sloc address space used.
For carbon.h:
27364 SLocEntry's allocated, 12398141B of Sloc address space used.
Clearly 2G of sloc address space should be enough for anyone?!
