combination.

Evan Cheng 1d78d3deeb New test case. 
llvm-svn: 35515
 2007-03-30 20:41:18 +00:00
Evan Cheng 9a2a7b174a Don't add the same MI to register reuse "last def/use" twice if it reads the 
register more than once.

llvm-svn: 35513
 2007-03-30 20:21:35 +00:00
Evan Cheng 48dd5e7d44 Bug fix for PR1279. When isDead is propagate by copy coalescing, we keep length 
of dead def live interval at 1 to avoid multiple def's targeting the same
register. The previous patch missed a case where the source operand is live-in.
In that case, remove the whole interval.

Evan Cheng 9ca63d605c Test case for PR1279 (part 2).

 2007-03-30 20:15:22 +00:00
Zhou Sheng fd28a33031 Make sure the use of ConstantInt::getZExtValue() for shift amount safe. 
llvm-svn: 35510
 2007-03-30 17:20:39 +00:00
Zhou Sheng 02d3ac6895 Make sure this method just return value equal or less than Limit. 
llvm-svn: 35509
 2007-03-30 16:50:28 +00:00
Reid Spencer 8c3d3dce2b For PR1293: 
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

 2007-03-30 16:41:50 +00:00
Duncan Sands 3bf01520eb Remove reference to checkpoint. 
llvm-svn: 35507
 2007-03-30 16:09:58 +00:00
Duncan Sands 16f122e6ad Various hopefully correct easy fixes. 
llvm-svn: 35506
 2007-03-30 12:22:09 +00:00
Zhou Sheng b25806fa5f 1. Make sure the use of ConstantInt::getZExtValue() for getting shift 
amount is safe.
2. Use new method on ConstantInt instead of (? :) operator.
3. Use new method uge() on ConstantInt to simplify codes.

llvm-svn: 35505
 2007-03-30 09:29:48 +00:00
Duncan Sands 3dd14331ac Correct typo. 
llvm-svn: 35504
 2007-03-30 06:39:42 +00:00
Zhou Sheng 5e60a4a6b0 Use APInt operation instead of ConstantExpr::getXX. 
llvm-svn: 35503
 2007-03-30 05:45:18 +00:00
Zhou Sheng 9737575772 Rename and correct the method "greaterOrEqual". 
llvm-svn: 35502
 2007-03-30 05:10:59 +00:00
Zhou Sheng 12b3549f5d Add two utility methods into ConstantInt.

Reid Spencer ef01c47512 For PR1289: Regenerate 
llvm-svn: 35500
 2007-03-30 01:37:39 +00:00
Reid Spencer cf2ccbff1a For PR1289: 
Check at the end of the parse that there are no unresolved types and no
undefined values. Issue errors if there are. This gets rid of the need
for implementation or checkpoint by ensuring you can't finish a parse with
undefined things.

llvm-svn: 35499
 2007-03-30 01:37:13 +00:00
Reid Spencer 3c401f0613 For PR1289: 
Remove an unneeded instance of "implementation" that soon won't be supported.

llvm-svn: 35498
 2007-03-30 01:35:32 +00:00
Bill Wendling 2fbcbc16b4 Add MMX calling conventions. 
llvm-svn: 35489
 2007-03-30 00:35:22 +00:00
Evan Cheng 045414aa8e New entry. 
llvm-svn: 35480
 2007-03-29 21:40:13 +00:00
Evan Cheng cc44b1e743 Can't re-materialize mov r, imm in thumb since mov would clobber the condition code. 
llvm-svn: 35479
 2007-03-29 21:38:31 +00:00
Reid Spencer d232f311cb Remove some non-sensical logic that prevented llvm-nm from working on any 
file other than one named "-".

llvm-svn: 35478
 2007-03-29 19:49:07 +00:00
Reid Spencer c7f485fd71 Use the stat information in the Path object, if it is already obtained. This 
avoids a call to ::fstat by MappedFile when the file size information was
already obtained by the Path object.

llvm-svn: 35477
 2007-03-29 19:11:22 +00:00
Reid Spencer 200c6f9c3d For PR789: 
Make the sys::Path::getFileStatus function more efficient by having it
return a pointer to the FileStatus structure rather than copy it. Adjust
uses of the function accordingly. Also, fix some memory issues in sys::Path.

llvm-svn: 35476
 2007-03-29 19:05:44 +00:00
Chris Lattner 7c82675afa the bytecode reader supports dematerializeFunction 
llvm-svn: 35475
 2007-03-29 18:58:08 +00:00
Reid Spencer b9d7f2a3ba checkpoint -> implementation. This really needs to just drop the need for 
a keyword by having the assembler check for incomplete types and values
upon end-of-file.

llvm-svn: 35474
 2007-03-29 18:56:58 +00:00
Reid Spencer 0833b81248 Regenerate. 
llvm-svn: 35473
 2007-03-29 18:50:01 +00:00
Reid Spencer 01a599a202 Give users a grace period on the implementation keyword. This *will* get 
removed in a few days.

llvm-svn: 35472
 2007-03-29 18:49:28 +00:00
Chris Lattner c3f4d87c90 add a hook to demat functions. 
llvm-svn: 35471
 2007-03-29 18:30:26 +00:00
Chris Lattner 323a5137c6 don't build runtime for now, ever 
llvm-svn: 35470
 2007-03-29 18:14:00 +00:00
Jeff Cohen 68e93b7c44 MS C does have inlining after all, just uses _inline instead of inline. 
llvm-svn: 35467
 2007-03-29 17:42:21 +00:00
Jeff Cohen 54a781be7d getFileStatus has a new parameter (caught by VC++).

Jeff Cohen 73926a5fb5 uniqueID is a uint64_t (caught by VC++) 
llvm-svn: 35465
 2007-03-29 17:28:31 +00:00
Jeff Cohen 60c5522467 Determine absolute paths the correct way :) 
llvm-svn: 35464
 2007-03-29 17:27:38 +00:00
Reid Spencer d394617a55 Add a uniqueID field to the FileStatus structure for Paths. This will map 
to the inode number on Unix and something far less unique on Windows. The
windows case needs to be improved.

llvm-svn: 35461
 2007-03-29 17:00:31 +00:00
Reid Spencer 858045e396 Don't forget to delete the FileStatus structure on destruction of Path.
