llvm-svn: 37042
 2007-05-14 18:32:56 +00:00
Evan Cheng bc5c15276b Remove duplicated line. 
llvm-svn: 37040
 2007-05-14 18:03:45 +00:00
Reid Spencer 9cdab38520 Reverse last patch .. premature. Depends on uncommitted CBE patch. 
llvm-svn: 37039
 2007-05-14 17:58:52 +00:00
Reid Spencer 9c6a4d64aa Update this test to match the (corrected) output from the CBE. 
llvm-svn: 37038
 2007-05-14 17:56:39 +00:00
Reid Spencer 764ae2a21b Give names to the final result values of the part_set computations. This 
just aids in readability and debugability of the output. No functional change.

llvm-svn: 37037
 2007-05-14 17:21:17 +00:00
Reid Spencer 146281ce1a The wrapping behavior of part_set is not desirable. Adjust the 
documentation to describe the desired behavior.

llvm-svn: 37036
 2007-05-14 16:50:20 +00:00
Reid Spencer 70845c05e4 Revise definition of part_select. The wrapping behavior is not useful so 
in the reverse case the only difference is that the bits are returned in
reverse order.

Dan Gohman 8d40e4d965 Correct a few comments. 
llvm-svn: 37034
 2007-05-14 14:31:17 +00:00
Dan Gohman 90d97ac1e6 Add passes -view-cfg and -view-cfg-only that are like -print-cfg and 
-print-cfg-only except they use the ViewCFG function, which displays the
CFG rendered with graphviz with gv.

llvm-svn: 37033
 2007-05-14 14:25:08 +00:00
Dan Gohman 86110bdf06 Use templates for the GraphType for DefaultDOTGraphTraits' members instead 
of just using void*. This allows it to be used with graph adapters like
Inverse.

llvm-svn: 37032
 2007-05-14 14:23:27 +00:00

addRequiredTransitive as addRequiredID is to addRequired.

Reid Spencer 98ed7db7ab Make the results for the rotate functions correct when rotateAmt == 0. 
llvm-svn: 37026
 2007-05-14 00:15:28 +00:00
Reid Spencer 4c50b52f63 Add some things needed by the llvm-gcc version supporting bit accurate integer 
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

Anton Korobeynikov 1ee0c8d563 Emit function debug frames in one atom. This will prevent us from generating incorrect assembler in case of both 
debug information & exception information presented.

llvm-svn: 37019
 2007-05-13 17:30:11 +00:00
Anton Korobeynikov bbaf55448b Emit multiple common EH frames for multiple (including blank) personality 
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.

llvm-svn: 37018
 2007-05-13 15:42:26 +00:00
Chris Lattner 8176a2f24e add initial description of llvm top-level stuff.

llvm-svn: 37016
 2007-05-13 00:59:52 +00:00
Anton Korobeynikov 13da17843c More DWARF-related things cleanup: 
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

llvm-svn: 37015
 2007-05-12 22:36:25 +00:00
Reid Spencer 81ee020f64 Fix shl to produce the correct result when the bitwidth is > 64 and the 
shift amount is 0. Previously this code would do a lshr by the bit width
which can lead to incorrect results.

llvm-svn: 37010
 2007-05-12 18:01:57 +00:00
Reid Spencer 5d22b630af Add a test case for shl of APInt integers > 64 bits by 0 shift amount.

llvm-svn: 36991
 2007-05-11 20:59:29 +00:00
Dan Gohman 2980d9da45 This patch extends the LoopUnroll pass to be able to unroll loops 
with unknown trip counts. This is left off by default, and a
command-line option enables it. It also begins to separate loop
unrolling into a utility routine; eventually it might be made usable
from other passes.

It currently works by inserting conditional branches between each
unrolled iteration, unless it proves that the trip count is a
multiple of a constant integer > 1, which it currently only does in
the rare case that the trip count expression is a Mul operator with
a ConstantInt operand. Eventually this information might be provided
by other sources, for example by a pass that peels/splits the loop
for this purpose.

to:

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:

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.

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

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.
