The size reduction in the RegDiffLists are rather dramatic. Here are a few size differences for MCTargetDesc.o files (before and after) in bytes: R600 - 36160B - 11184B - 69% reduction ARM - 28480B - 8368B - 71% reduction Mips - 816B - 576B - 29% reduction One side effect of dynamically computing the aliases is that the iterator does not guarantee that the entries are ordered or that duplicates have been removed. The documentation implies this is a safe assumption and I found no clients that requires these attributes (i.e., strict ordering and uniqueness). My local LNT tester results showed no execution-time failures or significant compile-time regressions (i.e., beyond what I would consider noise) for -O0g, -O2 and -O3 runs on x86_64 and i386 configurations. rdar://12906217 llvm-svn: 182783 |
