2008-03-25A quick nm audit turned up several fixed tables and objects that wereDan Gohman
marked read-write. Use const so that they can be allocated in a read-only segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48800 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-29Add support to APInt for shift and rotate operations with APIntDan Gohman
instead of uint32_t for the shift/rotate count operand type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47741 91177308-0d34-0410-b5e6-96231b3b80d8

annoying warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47367 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-19Fixed bug in APInt::Profile() where the BitWidth field was not included in theTed Kremenek
profile of the APSInt object. This caused unexpected Profile collisions where none should have occurred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47338 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-15Fixed bug in FoldingSetIteratorImpl where we did not correctly check ifTed Kremenek
we had reached the "fake bucket" after the last bucket, allowing the iterator in some cases to run off the end of the hashtable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47178 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-14Fix a warning about comparison between signed and unsigned,Dan Gohman
being consistent with the rest of the APInt implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47138 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47086 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-11Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46957 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-04Added "bucket_iterators" to FoldingSet. Bucket iterators allow iterationTed Kremenek
over all the nodes in a particular bucket. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46716 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-31Chris' change to print an approximation to long doublesDale Johannesen
exposed a bug in APFloat's long double->double conversion of NaNs. Broke several things in the ieee part of gcc testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46617 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-19Made 'FoldingSetNodeID' a proper class instead of a nested class inTed Kremenek
'FoldingSetNodeImpl' (previously 'FoldingSetNodeID' was a typedef of 'FoldingSetNodeImpl::NodeID'). Why? Clients can now easily forward declare 'FoldingSetNodeID' without having to include FoldingSet.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46187 91177308-0d34-0410-b5e6-96231b3b80d8

Restore an assertion that arithmetic can be performed on this format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43638 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-01When converting to integer, do bit manipulations in the destinationNeil Booth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43626 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-15Fast-track obviously over-large and over-small exponents during decimal->Neil Booth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42984 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-14Whether arithmetic is supported is a property of the semantics. Make itNeil Booth
so, and clean up the checks by putting them in an inline function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42965 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-14Separate out parsing of decimal number. Use this to only allocateNeil Booth
memory for the significand once up-front. Also ignore insignificant trailing zeroes; this saves unnecessary multiplications later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42964 91177308-0d34-0410-b5e6-96231b3b80d8
