2009-07-09Revert the part of 75177 that split ConstantRange into two classes, andDan Gohman
merge the new functionality and unittests into ConstantRange. Thanks to Nick Lewycky for pointing out that it isn't necessary to have two separate classes here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75191 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-09Add a ConstantSignedRange class, which does for signed integersDan Gohman
what ConstantRange does for unsigned integers. Factor out a common base class for common functionality. Add some new functions for performing arithmetic on constant ranges. Some of these are currently just stubbed out with conservative implementations. Add unittests for ConstantRange and ConstantSignedRange. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75177 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-23Switch the asmprinter (.ll) and all the stuff it requires over toChris Lattner
use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55263 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-17Rework the routines that convert AP[S]Int into a string. Now, instead ofChris Lattner
returning an std::string by value, it fills in a SmallString/SmallVector passed in. This significantly reduces string thrashing in some cases. More specifically, this: - Adds an operator<< and a print method for APInt that allows you to directly send them to an ostream. - Reimplements APInt::toString to be much simpler and more efficient algorithmically in addition to not thrashing strings quite as much. This speeds up llvm-dis on kc++ by 7%, and may also slightly speed up the asmprinter. This also fixes a bug I introduced into the asmwriter in a previous patch w.r.t. alias printing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54873 91177308-0d34-0410-b5e6-96231b3b80d8

2007-01-19For PR1043:Reid Spencer
This is the final patch for this PR. It implements some minor cleanup in the use of IntegerType, to wit: 1. Type::getIntegerTypeMask -> IntegerType::getBitMask 2. Type::Int*Ty changed to IntegerType* from Type* 3. ConstantInt::getType() returns IntegerType* now, not Type* This also fixes PR1120.
