Ted Kremenek 55e30be8ec Added "random access" to the Deserializer to allow a client to jump to any 
serialized block in the bitstream, including a block in an entirely different
nesting than the current block. This is useful for deserializing objects from
a bitstream in an order different from the order that they were serialized.

Ted Kremenek a7f49ce570 Made Deserializer a friend class of BitstreamReader. 
Moved some of the logic in BitstreamReader::ExitBlock into a utility function
BitstreamReader::PopBlockScope. The latter is a private method. It will also
be called by Deserializer to manipulate the current "block scope."

Chris Lattner f9c0fd7488 Tighten up a check for folding away loads from (newly constant) globals. This

rdar://5585488.

Duncan Sands e7a9ac929f Fix some load/store logic that would be wrong for 
apints on big-endian machines if the bitwidth is
not a multiple of 8.  Introduce a new helper,
MVT::getStoreSizeInBits, and use it.

Evan Cheng 797d56ff17 Much improved pic jumptable codegen: 
Then:
        call    "L1$pb"
"L1$pb":
        popl    %eax
		...
LBB1_1: # entry
        imull   $4, %ecx, %ecx
        leal    LJTI1_0-"L1$pb"(%eax), %edx
        addl    LJTI1_0-"L1$pb"(%ecx,%eax), %edx
        jmpl    *%edx

        .align  2
        .set L1_0_set_3,LBB1_3-LJTI1_0
        .set L1_0_set_2,LBB1_2-LJTI1_0
        .set L1_0_set_5,LBB1_5-LJTI1_0
        .set L1_0_set_4,LBB1_4-LJTI1_0
LJTI1_0:
        .long    L1_0_set_3
        .long    L1_0_set_2

Now:
        call    "L1$pb"
"L1$pb":
        popl    %eax
		...
LBB1_1: # entry
        addl    LJTI1_0-"L1$pb"(%eax,%ecx,4), %eax
        jmpl    *%eax

		.align  2
		.set L1_0_set_3,LBB1_3-"L1$pb"
		.set L1_0_set_2,LBB1_2-"L1$pb"
		.set L1_0_set_5,LBB1_5-"L1$pb"
		.set L1_0_set_4,LBB1_4-"L1$pb"
LJTI1_0:
        .long    L1_0_set_3
        .long    L1_0_set_2

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.

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.

dereference.

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

llvm-svn: 43852
 2007-11-07 23:18:40 +00:00
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).
