Jakob Stoklund Olesen 0241308954 Expand V_SET0 to xorps by default. 
The xorps instruction is smaller than pxor, so prefer that encoding.

The ExecutionDepsFix pass will switch the encoding to pxor and xorpd
when appropriate.

Eric Christopher 4996c70034 Add the support code to enable the dwarf accelerator tables. Upcoming patches 
to fix the types section (all types, not just global types), and testcases.

The code to do the final emission is disabled by default.

 2011-11-07 09:24:32 +00:00
Eric Christopher 6e47204b0c Add a new dwarf accelerator table prototype with the goal of replacing 
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.
