df799afbec Fix some sporadic segfaults that are triggered when SmallVector's heap
storage lands near the end of the available address space. In the expression
Begin+N > Capacity, the Begin+N was overflowing. Fix this by replacing it
by with an expression that doesn't involve computation of an address
beyond the end of allocated memory.

19dc32a2d4 Add some things needed by the llvm-gcc version supporting bit accurate integer
types:
1. Functions to compute div/rem at the same time.
2. Further assurance that an APInt with 0 bitwidth cannot be constructed.
3. Left and right rotate operations.
4. An exactLogBase2 function which requires an exact power of two or it
   returns -1.

47e756c11e Commit an patch from Gabor Greif in Mar 2005. This eliminates the tail
pointer from ilist, storing it in the prev pointer of the first node in the
list instead.

This shrinks ilist from 8 to 4 bytes, BasicBlock from 40->36 bytes, Function
from 76->68 bytes, Module from 52->44 bytes.

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.

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.

681dcd14e9 Implement countLeadingOnes() and getMinSignedBits(). This helps to minimize
the bit width of negative numbers by computing the minimum bit width for a
negative value. E.g. 0x1800000000000000 could be just 0x8000000000000000

when the bit size is equal to the word size. This happens to work out okay

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

Also, move some comments from .cpp file into header.

   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.

d0f285e212 Add a class APInt to represent arbitrary precision constant integral values.
It is a functional replacement for common case integer type like "unsigned",
"uint64_t", but also allows non-byte-width integer type and large integer
value types such as 3-bits, 15-bits, or more than 64-bits of precision. For
more details, see pr1043.

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.

d0337c1678 Remove assertions from the SmallVector class. They slow down clients of
smallvector too much in a release build.  Removing them speeds up isel 4%.

f282654021 Add a new llvm::SmallVector template, which is similar to the vector class, but
contains optimizations to avoid heap allocation if the vector size is smaller
than some threshold.  This can significantly improve the performance of code
that allocates many small vectors by eliminating tons of small malloc/free's.

6fb568f77e Fix utostr once and for all, by making there only be one function named
utostr.  To keep the efficiency in the 32-bit case, make it check to see if
the value is 32-bits and if so switch over to the faster 32-bit case.
