Adrian Prantl 6ee02c7fce PR26055: Speed up LiveDebugValues by replacing lists with bitvectors. ... This patch modifies the LiveDebugValues pass to use more efficient set data structures as outlined in PR26055. Both VarLocSet and VarLocList are now SparseBitVectors which allows us to perform much faster bitvector arithmetic on them. The speedup can be in the order of minutes especially on ASANified code. The change is not NFC in the assembler output because the inserted DBG_VALUEs are now sorted by variable and location. Many thanks to Daniel Berlin for helping design the improved algorithm and reviewing the patch. https://llvm.org/bugs/show_bug.cgi?id=26055 http://reviews.llvm.org/D20178 rdar://problem/24091200 llvm-svn: 270776		2016-05-25 22:21:12 +00:00
