Duncan P. N. Exon Smith 24ad5c9e05 AsmPrinter: Make DIEString small ... Expose the `DwarfStringPool` entry in a header, and store a pointer to it directly in `DIEString`. Instead of choosing at creation time how to emit it, use the `dwarf::Form` to determine that at emission time. Besides avoiding the other `DIEValue`, this shaves two pointers off of `DIEString`; the data is now a single pointer. This is a nice cleanup on its own -- and drops memory usage from 861 MB down to 853 MB, around 0.9% -- but it's also preparation for passing `DIEValue`s by value. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc`; see r236629 for details.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238117 91177308-0d34-0410-b5e6-96231b3b80d8		2015-05-24 16:40:47 +00:00
