Chris Lattner 7dce4b04ca add a 6-bit encoding type for strings. 
llvm-svn: 36770
 2007-05-05 01:15:42 +00:00
Chris Lattner de05f6be35 add an abbreviation for the type symtab, this shrinks the TST from 175197 bits 
to 103165 bits:

Chris Lattner 9181ddf91d update to new APIs, make output a bit (haha) nicer

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):

         Total Size: 1.29508e+07b/1.61885e+06B/404713W

to:

    Tot/Avg Abbrevs: 0/0
    Tot/Avg Records: 120924/51.5667

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

Chris Lattner fd1ad10e61 shave another 150K off of kc++, by using a 7-bit encoding for BB names 
where we can.  This shrinks kc++'s down to 3368K, with a VST record of:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.29508e+07b/1.61885e+06B/404713W

    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667

Isn't it nice to be able to optimizer bc size without touching the reader? :)

Chris Lattner 4d92598ab0 where possible, encode symtab names with 7 bits per char instead of 8. This 
shaves 110K off kc++ to 3514K.  Before:

Bill Wendling e6182267d7 Add an "implies" field to features. This indicates that, if the current 
feature is set, then the features in the implied list should be set also.
The opposite is also enforced: if a feature in the implied list isn't set,
then the feature that owns that implies list shouldn't be set either.

Dan Gohman 2bcbd5b7ca Use IntrinsicInst to test for prefetch instructions, which is ever so

Chris Lattner 430e80d670 optimize constant layout. This fixes encoding of 181.mcf (by ensuring 
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.

Chris Lattner a919f6dddc if functiontype is going to have a pointer to a paramattr object, it better 
be const.  The only way to get a pointer to these returns a const pointer.

Reid Spencer 0454316c79 Bitcast all the bits of a floating point value, not just one. The zero 
extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.
