* Fix a bug that caused opt and other tools to silently ignoreDan Gohman2008-02-231-1/+1
| | | | | | invalid command-line options. llvm-svn: 47523
* Add explicit keywords.Dan Gohman2008-02-201-2/+2
| | | | llvm-svn: 47382
* Add 'sink' cmdline option. Patch by Mikhail Glushenkov!Anton Korobeynikov2008-02-201-6/+18
| | | | llvm-svn: 47377
* Unbreak build with gcc 4.3: provide missed includes and silence most ↵Anton Korobeynikov2008-02-205-0/+5
| | | | | | annoying warnings. llvm-svn: 47367
* Fixed bug in APInt::Profile() where the BitWidth field was not included in theTed Kremenek2008-02-191-0/+2
| | | | | | | profile of the APSInt object. This caused unexpected Profile collisions where none should have occurred. llvm-svn: 47338
* Fixed bug in FoldingSetIteratorImpl where we did not correctly check ifTed Kremenek2008-02-151-2/+4
| | | | | | | we had reached the "fake bucket" after the last bucket, allowing the iterator in some cases to run off the end of the hashtable. llvm-svn: 47178
* Fix a warning about comparison between signed and unsigned,Dan Gohman2008-02-141-1/+1
| | | | | | being consistent with the rest of the APInt implementation. llvm-svn: 47138
* Add countTrailingOnes member functions to APInt.Dan Gohman2008-02-131-0/+12
| | | | llvm-svn: 47086
* Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek2008-02-112-11/+6
| | | | | | | | | | Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary objects to a profile via dispatch to FoldingSetTrait<T>::Profile(). Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their functionality is now replaced using the above mentioned member template. llvm-svn: 46957
* Add support to FoldingSet for hashing APInt objects.Dan Gohman2008-02-061-0/+4
| | | | llvm-svn: 46833
* Added "bucket_iterators" to FoldingSet. Bucket iterators allow iterationTed Kremenek2008-02-041-1/+7
| | | | | | over all the nodes in a particular bucket. llvm-svn: 46716
* Fixed 80 col. violation.Ted Kremenek2008-02-041-2/+4
| | | | llvm-svn: 46709
* Chris' change to print an approximation to long doublesDale Johannesen2008-01-311-1/+2
| | | | | | | exposed a bug in APFloat's long double->double conversion of NaNs. Broke several things in the ieee part of gcc testsuite. llvm-svn: 46617
* Remove top-level const qualifiers from casts, avoiding associatedDan Gohman2008-01-291-10/+10
| | | | | | compiler warnings. llvm-svn: 46509
* Simplify the code and fix a typo.Lauro Ramos Venancio2008-01-281-7/+4
| | | | llvm-svn: 46458
* Fix fpcmp infinite loop when comparing "29-266" with "29-268".Lauro Ramos Venancio2008-01-281-5/+21

* Added FoldingSet style 'profiling' support for APSInt.Ted Kremenek2008-01-191-0/+23

* Added FoldingSet style 'profiling' support for APInt.Ted Kremenek2008-01-191-1/+13
| | | | llvm-svn: 46188
* Made 'FoldingSetNodeID' a proper class instead of a nested class inTed Kremenek2008-01-191-19/+19
| | | | | | | | | | 'FoldingSetNodeImpl' (previously 'FoldingSetNodeID' was a typedef of 'FoldingSetNodeImpl::NodeID'). Why? Clients can now easily forward declare 'FoldingSetNodeID' without having to include FoldingSet.h. llvm-svn: 46187
* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-2925-50/+50
| | | | llvm-svn: 45418
* remove attribution from lib Makefiles.Chris Lattner2007-12-291-2/+2
| | | | llvm-svn: 45415
* Cygwin defines uint32_t as unsigned long. Unbreak call to std::min in this caseAnton Korobeynikov2007-12-241-1/+1
| | | | llvm-svn: 45342
* Don't have APInt.cpp depend upon DerivedTypes.h. This helps with splitting theReid Spencer2007-12-111-14/+23
| | | | | | Support libraries separately into their own module. llvm-svn: 44852

* Fix PR1816, by correcting the broken definition of APInt::countTrailingZeros.Chris Lattner2007-11-231-1/+1
| | | | llvm-svn: 44296
* Fix APInt::countTrailingZeros to return BitWidth if the input is zero ↵Chris Lattner2007-11-231-2/+2
| | | | | | instead of returning some random large number. llvm-svn: 44294
* Fix the Linker testcase regressions, by making MemoryBuffer::getFileOrSTDIN ↵Chris Lattner2007-11-181-0/+18

* Fix denormal check in float->APInt conversion.Dale Johannesen2007-11-171-1/+1
| | | | | | PR 1804. llvm-svn: 44201
* make smallptrset more const and type correct, which caught a fewChris Lattner2007-11-061-2/+2
| | | | | | minor bugs. llvm-svn: 43782
* Remove some unnecessary C-style statics.Neil Booth2007-11-021-6/+8
| | | | | | Restore an assertion that arithmetic can be performed on this format. llvm-svn: 43638
* Add back line whose removal somehow crept into prior patchNeil Booth2007-11-011-0/+1
| | | | llvm-svn: 43627
* When converting to integer, do bit manipulations in the destinationNeil Booth2007-11-011-71/+107
| | | | | | | | | | | memory rather than in a copy of the APFloat. This avoids problems when the destination is wider than our significand and is cleaner. Also provide deterministic values in all cases where conversion fails, namely zero for NaNs and the minimal or maximal value respectively for underflow or overflow. llvm-svn: 43626
* Clarified operator precedence.Hartmut Kaiser2007-10-251-2/+2
| | | | | | Silenced VC++ warning. llvm-svn: 43372
* This requires rtti info because tblgen uses commandline,Chris Lattner2007-10-181-1/+4
| | | | | | and tblgen requires rtti. llvm-svn: 43127
* Fast-track obviously over-large and over-small exponents during decimal->Neil Booth2007-10-151-8/+44
| | | | | | | | | | integer conversion. In some such cases this makes us one or two orders of magnitude faster than NetBSD's libc. Glibc seems to have a similar fast path. Also, tighten up some upper bounds to save a bit of memory. llvm-svn: 42984
* Consolidate logic for creating NaNs. Silence compiler warning.Neil Booth2007-10-141-10/+15
| | | | llvm-svn: 42966
* Whether arithmetic is supported is a property of the semantics. Make itNeil Booth2007-10-141-41/+36
| | | | | | so, and clean up the checks by putting them in an inline function. llvm-svn: 42965
* Separate out parsing of decimal number. Use this to only allocateNeil Booth2007-10-141-97/+150
| | | | | | | memory for the significand once up-front. Also ignore insignificant trailing zeroes; this saves unnecessary multiplications later. llvm-svn: 42964
* If the power of 5 is exact, and the reciprocal exact, the error is zero not ↵Neil Booth2007-10-131-1/+1
| | | | | | one half-ulps. This prevents an infinite loop in rare cases. llvm-svn: 42950
* Remove duplicate comment.Neil Booth2007-10-121-11/+0
| | | | llvm-svn: 42913
* Implement correctly-rounded decimal->binary conversion, i.e. conversionNeil Booth2007-10-121-6/+349
| | | | | | | | | | | from user input strings. Such conversions are more intricate and subtle than they may appear; it is unlikely I have got it completely right first time. I would appreciate being informed of any bugs and incorrect roundings you might discover. llvm-svn: 42912
* Remove a field that was never used.Neil Booth2007-10-121-9/+6
| | | | llvm-svn: 42911
* If we're trying to be arbitrary precision, unsigned char clearly won't cut ↵Neil Booth2007-10-121-1/+1
| | | | | | it. Needed for dec->bin conversions. llvm-svn: 42910
* Don't attempt to mask no bitsNeil Booth2007-10-121-1/+2
| | | | llvm-svn: 42909
* Next PPC long double bits. First cut at constants.Dale Johannesen2007-10-111-6/+157
| | | | | | | | | No compile-time support for constant operations yet, just format transformations. Make readers and writers work. Split constants into 2 doubles in Legalize. llvm-svn: 42865
* Add new MemoryBuffer::getMemBufferCopy method.Chris Lattner2007-10-091-2/+15
