Duncan P. N. Exon Smith 583dac827c AsmPrinter: Compute absolute label difference directly ... Create a low-overhead path for `EmitLabelDifference()` that emits a emits an absolute number when (1) the output is an object stream and (2) the two symbols are in the same data fragment. This drops memory usage on Mach-O from 975 MB down to 919 MB (5.8%). The only call is when `!doesDwarfUseRelocationsAcrossSections()` -- i.e., on Mach-O -- since otherwise an absolute offset from the start of the section needs a relocation. (`EmitLabelDifference()` is cheaper on ELF anyway, since it creates 1 fewer temp symbol, and it gets called far less often. It's not clear to me if this is even a bottleneck there.) (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@237876 91177308-0d34-0410-b5e6-96231b3b80d8		2015-05-21 02:41:23 +00:00
