Ted Kremenek 1d9406c1ca Updated Deserializer class to provide more information about the current 
block that is being visited in the bitstream.  The client can also now
skip blocks before reading them, and query the current abbreviation number
as seen from the perspective of the Deserializer.  This allows the client
to be more interactive in the deserialization process (if they so choose).

Ted Kremenek 67135ebaff Added typedef "SerializedPtrID" to represent the pointer handle written to disk 
instead of just using "unsigned".  This gives us more flexibility in changing
the definition of the handle later, and is more self-documenting.

Added tracking of block stack in the Deserializer.  Now clients can query
if they are still within a block using the methods GetCurrentBlockLocation()
and FinishedBlock().

Owen Anderson 0be8c1dafe Add the majority of machine-level critical edge breaking pass. Most of this was written by Fernando, cleanup and updating to TOT by me. 
This still needs a bit of work, particularly to handle jump tables properly.

Ted Kremenek 89704afa43 Revised BatchEmitOwnedPtrs to work better with constant pointers. 
llvm-svn: 43861
 2007-11-08 00:55:31 +00:00
Ted Kremenek 8f74abd34a Revised implementation of BatchReadOwnedPtrs() that deserializes an 
array of pointers to not allocate a second array to contain the pointer ids.

Fixed bug in the same member function where deserialized pointers were
not being registered with the backpatcher.

Ted Kremenek 14b5fe537e Fixed bug where we did not properly serialize owned objects due to a missing

Ted Kremenek 1125bfa648 Added version of BatchEmitOwnedPtrs and BatchReadOwnedPtrs that emits/reads 
an array of pointers of the same type.

Ted Kremenek e079cb7b08 Added methods to batch emit and deserialize owned pointers. This allows 
to group the pointer IDs together in the bitstream before their referenced
contents (which will lend itself to more efficient encoding).

Dale Johannesen 1b9de4dd6f Complete conditionalization of Dwarf reg numbers. 
Would somebody not on Darwin please make sure this
doesn't break anything.  Exception handling failures
would be the most likely symptom.

Ted Kremenek ee4e7d4f25 Added special version of ReadPtr() that returns a deserialized pointer 
by value.  This version prohibits backpatching of pointers, so it
useful when a pointee is always known to be deserialized beforehand.

Duncan Sands f042e862fd At the point of calculating the shift amount, the 
type of SV has changed from what it originally was.
