Dale Johannesen bed9dc423c Next round of APFloat changes. 
Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove
the ConstantFP double interfaces.
Use APFloat functions for constant folding arithmetic
and comparisons.
(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

David Greene c656cbb8c2 Update GEP constructors to use an iterator interface to fix 
GLIBCXX_DEBUG issues.

David Greene 703623d571 Update InvokeInst to work like CallInst

 2007-08-27 19:04:21 +00:00
Dale Johannesen bdad80977b Patch 10 for long double. Doing constants right needs expanding ConstantFP 
to handle values bigger than double.  If we assume host==target and host
long double works correctly, this is not too bad, but we don't want to
have that limitation longterm.  I could implement accepting double
constants as long double or something like that, which would lead to
incorrect codegen with no errors; the more I think about that the worse
it seems.  Rather than do such a hack that would be backed out later,
I'm settling for giving reasonable error messages, for now.

Chandler Carruth 7132e00de7 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. 
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

 2007-05-06 00:53:07 +00:00
Chris Lattner 4b6ce8fa59 add an abbreviation for the string constants opzn, shrinking the constnats 
block from:

  Block ID #11 (CONSTANTS_BLOCK):

This shrinks kc++ from 2815788 to 2724088 bytes, which means the bitcode
file is now smaller than the bytecode file.

llvm-svn: 36820
 2007-05-06 00:42:18 +00:00

 2007-05-05 07:36:14 +00:00
Chris Lattner ccee706345 Add abbreviations to the TYPE_BLOCK for pointers, functions, structs and arrays. 
This shrinks the type_block of kc++ from 139901 bits to 99389 bits (0.55% to 0.39%
of the file), a 40% reduction.

This shrink the record from:

 2007-05-05 06:30:12 +00:00
Chris Lattner e760d6f4c1 add a char6 abbrev for bbnames and value names. This represents each character 
with 6 bits where possible.  This shrinks kc++ from 3324164B to 3183584B.  The
old VST was:

  Block ID #14 (VALUE_SYMTAB):
         Total Size: 1.26713e+07b/1.58391e+06B/395978W
       Average Size: 5403.53b/675.442B/168.86W
          % of file: 47.6484

The new one is:

  Block ID #14 (VALUE_SYMTAB):
         Total Size: 1.15467e+07b/1.44334e+06B/360834W
       Average Size: 4923.96b/615.495B/153.874W
          % of file: 45.3368

This is 11% smaller than the VST in the bytecode format.

llvm-svn: 36771
 2007-05-05 01:26:50 +00:00
Chris Lattner de05f6be35 add an abbreviation for the type symtab, this shrinks the TST from 175197 bits

llvm-svn: 36769
 2007-05-05 00:47:19 +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:

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

Chris Lattner 430e80d670 optimize constant layout. This fixes encoding of 181.mcf (by ensuring

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.

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
}

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.
