* Kill and collapse outstanding DomainValues.Jakob Stoklund Olesen2011-11-071-5/+14
| | | | | | | | | | | | DomainValues that are only used by "don't care" instructions are now collapsed to the first possible execution domain after all basic blocks have been processed. This typically means the PS domain on x86. For example, the vsel_i64 and vsel_double functions in sse2-blend.ll are completely collapsed to the PS domain instead of containing a mix of execution domains created by isel. llvm-svn: 144037

* Use a reverse post order instead of a DFS order.Jakob Stoklund Olesen2011-11-071-6/+5
| | | | | | | | The enterBasicBlock() function is combining live-out values from predecessor blocks. The RPO traversal means that more predecessors have been visited when that happens, only back-edges are missing. llvm-svn: 144025

* Add a new dwarf accelerator table prototype with the goal of replacingEric Christopher2011-11-072-0/+504
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the pubnames and pubtypes tables. LLDB can currently use this format and a full spec is forthcoming and submission for standardization is planned. A basic summary: The dwarf accelerator tables are an indirect hash table optimized for null lookup rather than access to known data. They are output into an on-disk format that looks like this: .-------------. | HEADER | |-------------| | BUCKETS | |-------------| | HASHES | |-------------| | OFFSETS | |-------------| | DATA | `-------------' where the header contains a magic number, version, type of hash function, the number of buckets, total number of hashes, and room for a special struct of data and the length of that struct. The buckets contain an index (e.g. 6) into the hashes array. The hashes section contains all of the 32-bit hash values in contiguous memory, and the offsets contain the offset into the data area for the particular hash. For a lookup example, we could hash a function name and take it modulo the number of buckets giving us our bucket. From there we take the bucket value as an index into the hashes table and look at each successive hash as long as the hash value is still the same modulo result (bucket value) as earlier. If we have a match we look at that same entry in the offsets table and grab the offset in the data for our final match. llvm-svn: 143921
