Dan Gohman <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution| |FIXED --- Comment #13 from Dan Gohman <[email protected]> 2009-05-11 21:36:47 --- After a long series of patches, culminating with this patch: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20090511/077422.html all of these loops are now optimized down to four instructions: store, inc, cmp, jne. All the arithmetic is now done at "word" size. There are a few more minor opportunities remaining; the cmp could be eliminated by making the loop count to zero instead of from zero, and the loop could be made to use one register instead of two via full strength reduction, however all the issues specific to non-"word" index types are now addressed. -- Configure bugmail: http://llvm.org/bugs/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ LLVMbugs mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/llvmbugs
