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.

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.

removed in a few days.

Jeff Cohen 68e93b7c44 MS C does have inlining after all, just uses _inline instead of inline.

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.

Reid Spencer 78b899f665 For PR789: 
Updates for change in interface of getFileStatus method of sys::Path class.

llvm-svn: 35458
 2007-03-29 16:48:16 +00:00
Reid Spencer 0f92f0e519 For PR789: 
* Add a method: bool isAbsolute() const, which determines if the path name
  is absolute or not.
* Implement caching of file status information in the Path object. Allow it
  to be updated forcefully or lazily re-fetched from the cached value.

Zhou Sheng b3a80b1d70 1. Make more use of APInt::getHighBitsSet/getLowBitsSet. 
2. Let APInt variable do the binary operation stuff instead of using
   ConstantExpr::getXXX.

Zhou Sheng a4475575c0 Clean up codes in InstCombiner::SimplifyDemandedBits(): 
1. Line out nested call of APInt::zext/trunc.
2. Make more use of APInt::getHighBitsSet/getLowBitsSet.
3. Use APInt[] operator instead of expression like "APIntVal & SignBit".

Zhou Sheng 4961cf1c06 1. Make the APInt variable do the binary operation stuff if possible 
instead of using ConstantExpr::getXX.
2. Use constant reference to APInt if possible instead of expensive
   APInt copy.

Devang Patel 0b013d578d It is not possible to determine dominance between two PHI nodes 
based on their ordering. This is applicable to ETForest::dominates() also.

Reid Spencer 2e35a58838 Replace the "implementation" keyword with "checkpoint". This more accurately 
describes its function as check against unresolved types and definitions.
This is handy for forcing error messages in assembly test cases or otherwise
ensuring that everything is resolved at that point in the assembly.

Evan Cheng 07c42d43a2 GEP index sinking fixes: 
1) Take address scale into consideration. e.g. i32* -> scale 4.
2) Examine all the users of GEP.
3) Generalize to inter-block GEP's (no longer uses loopinfo).
4) Don't do xform if GEP has other variable index(es).

Reid Spencer a5c18bf798 For PR1280: 
When converting an add/xor/and triplet into a trunc/sext, only do so if the
intermediate integer type is a bitwidth that the targets can handle.

 2007-03-28 01:36:16 +00:00
Evan Cheng b41697c006 Fix for PR1279. Dead def has a live interval of length 1. Copy coalescing should 
not violate that.

char" and it is up to the compilers implementation or the platform which is
followed."
