f6bef488ee Compute getLowBitsSet correctly. Using the complement of a 64-bit value 
and shifting down without regard for the bitwidth of the APInt can lead
to incorrect initialization values. Instead, check for the word size case
(to avoid undef results from shift) and then do (1 << loBitsSet) - 1

a1689ea60e Actually, for getHighBitsSet and getLowBitsSet, don't make a 0 bit size 
illegal. Instead do the 0 valued construction for the user. This is because
the caller may not know (or care to check) that the number of bits set is
zero.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35315 91177308-0d34-0410-b5e6-96231b3b80d8

Reid Spencer
758d1bc919 Make it illegal to set 0 bits in getHighBitsSet and getLowBitsSet. For that 
they should have used the uint64_t constructor. This avoids causing
undefined results via shifts by the word size when the bit width is an
exact multiple of the word size.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35313 91177308-0d34-0410-b5e6-96231b3b80d8

Reid Spencer
5b7e659e22 In the getBitsSet function, don't optimize for a common case that is 
already covered by getLowBitsSet (i.e. when loBits==0). Consequently, remove
the default value for loBits and reorder the arguments to the more natural
loBits, hiBits order. This makes it more clear that this function is for bit
groups in the middle of the bit width and not towards one end or the other.

there are no bits to clear (because BitWidth is a multiple of the word size)

a932e3f799 1. "unsigned" -> "uint32_t" to gaurantee its bit width on all platforms. 
Size matters in this case.
2. Remove the unused whichByte private function, which was also broken.
3. Remove the non-const overload of the getWord function, getWord() is
   never used as an lvalue.
4. Rename some local variables for clarity (e.g. API -> Result).

e81d2dad2c Review changes: 
1. Function style changes.
2. 80-col violations.
3. Better names for things.
4. Arrange constructors so they all take bit width first.
5. Add named signed and unsigned comparison functions and remove the
   corresponding operators.
6. Remove operator&& and operator|| but provide a getBoolValue function which
   converts to bool as comparison against 0. This allows the normal && and
   || operators to be used as if (X.getBoolValue() && Y.getBoolValue())

Note: this still doesn't function 100% yet. I'm working on the bugs now.

af3056c97e Fix a limitation of SmallPtrSet. Before it would assert if the smallsize 
was not a power of two.  Now it rounds up to the next power of two internally.

ecb2768758 Refactor statistic a big and introduce a horrible-but-necessary macro 
(STATISTIC), which allows us to define statistics that don't introduce
static ctors into the .o files.  I'm migrating code over to use this
incrementally.

5c7e326585 Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

975f05852d Change the implementation of statistic to not need destructors at all. 
Instead, the stat info is printed when llvm_shutdown() is called.
These also don't need static ctors, but getting rid of them is uglier:
still investigating.  This reduces the number of static dtors in llvm from
~1400 to ~750.
