Chris Lattner f25f710c4d add a denser encoding for null terminated strings, add a 6-bit abbrev as 
well.  This shrinks kc++ from 2724088 to 2717360 bytes.

Chris Lattner 6eeea5dc05 add support for BLOCKINFO records at the module level. This fixes the reader 
issues reid noticed last night.

llvm-svn: 36785
 2007-05-05 18:57:30 +00:00
Chris Lattner 982ec1eddc Implement support for globally associating abbrevs with block IDs, which 
relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.

The VST went from:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.29508e+07b/1.61885e+06B/404713W
       Average Size: 5522.73b/690.342B/172.585W
          % of file: 48.0645
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

to:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.26713e+07b/1.58391e+06B/395978W

    Tot/Avg Abbrevs: 0/0
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

because we didn't emit the same 3 abbrevs 2345 times :)

Chris Lattner 4704527576 Encoding calling conv info in call/invoke instrs, tree add now round trips completely 
llvm-svn: 36707
 2007-05-03 22:34:03 +00:00
Chris Lattner c1d86cda8c the type field for a store is the type of the pointer, not the value. 
With this fix I can round trip treeaadd, only losing calling conv info.

 2007-05-02 05:16:49 +00:00
Chris Lattner e53603e4e2 read a few instructions, fix some bugs. This is enough to be able to round 
trip function bodies like this:

define <2 x i64> @foo(<2 x i64> %x, <2 x i64> %y) {
        %tmp4 = bitcast <2 x i64> %y to <8 x i16>               ; <<8 x i16>> [#uses=1]
        %tmp5 = bitcast <2 x i64> %x to <8 x i16>               ; <<8 x i16>> [#uses=1]
        %tmp = add <8 x i16> %tmp5, %tmp4               ; <<8 x i16>> [#uses=1]
        %tmp6 = bitcast <8 x i16> %tmp to <2 x i64>             ; <<2 x i64>> [#uses=1]
        ret <2 x i64> %tmp6
}

visibility support for bitcode.

 2007-04-29 20:56:48 +00:00
Chris Lattner 6694f60bec Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.

easy breakpointing).

 2007-04-22 18:49:32 +00:00
Chris Lattner 1314b9996d Initial support for reading bitcode files. They currently only read types, 
the type symtab, and global/function protos, and are missing the important
size optimization, but it is a place to start.
