Reid Spencer 9329e7b626 Implement a getBitsNeeded method to determine how many bits are needed to 
represent a string in binary form by an APInt.

Dan Gohman a789d31517 Rename Value::getValueType to getValueID, to avoid confusion with 
other things named getValueType.

Chris Lattner e71f1447f7 CSE simple binary expressions when they are inserted. This makes LSR produce 
less huge code that needs to be cleaned up by sdisel.

Chris Lattner af039c53c0 improve the patch for PR1318 to also support grouped options with custom 
handlers (like the pass list).  My previous fix only supported *new* command
line options, not additions to old ones.

This fixes test/Feature/load_module.ll

Reid Spencer a472f66dd0 For PR1146: 
Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

Reid Spencer d3f622e0d5 Teach sys::Path how to recognize different kinds of object files for ELF 
and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

Reid Spencer ce38beb6a4 For PR1146: 
* Add ParamAttrs to InvokeInst class too.
* Make sure all initializes of ParamAttrs in CallInst and InvokeInst are 0
* Destruct the ParamAttrs in Call/Invoke destructors to avoid memory
  leaks. This will change when ParamAttrsList is uniquified but needs to
  be correct until then.

Reid Spencer 019c8869ed For PR1146:

Anton Korobeynikov 506eaf7915 Next stage into switch lowering refactoring 
1. Fix some bugs in the jump table lowering threshold
2. Implement much better metric for optimal pivot selection
3. Tune thresholds for different lowering methods
4. Implement shift-and trick for lowering small (<machine word
length) cases with few destinations. Good testcase will follow.

Reid Spencer 1ba12951e4 For PR1146:

their own object defined in ParameterAttributes.h now.

Owen Anderson 6978893a8f Move isReachableFromEntry out of line to avoid an unnecessary #include 
llvm-svn: 35797
 2007-04-09 04:07:36 +00:00
Reid Spencer bdcf9d6f08 Chris convinced me that the default size of the SmallVector (2) was too 
small.  Since it doesn't cost much to have 2 more (8 bytes), but not having
them would require a malloc as soon as the third one is needed. Setting
the default to 4 delays the malloc until the 5th parameter attribute.

Reid Spencer f71c15bda6 Implement more feedback: 
* Allow attributes to be added and removed singly or jointly so that in
  the future something like -pruneh can manipulate them more easily.
* Move functions generally only useful for LLVM internals to the end of
  the accessors list instead of the beginning.

Owen Anderson f7ebea1b9f Add DomSet back, and revert the changes to LoopSimplify. Apparently the 
ETForest updating mechanisms don't work as I thought they did.  These changes
will be reapplied once the issue is worked out.

llvm-svn: 35741

Chris Lattner 5247f60d20 rearchitect the registration mechanism used by the command line option stuff. 
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.

llvm-svn: 35701
 2007-04-06 21:06:55 +00:00
Chris Lattner d31e5155be Switch some vectors to smallvectors. This reduces amount of malloc'd 
memory that occurs before main starts from 5104 to 4864 bytes with a dummy
example app.

Chris Lattner 9df6baa772 Add a helper class (APSInt) which can represent an APInt along with sign 
information.  This is useful when a value does have a sign associated with
it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.
