A quick nm audit turned up several fixed tables and objects that were
marked read-write. Use const so that they can be allocated in a
read-only segment.

llvm-svn: 48800

Add assert for non-hexadecimal radixes.

llvm-svn: 48421

Fix a typo. It's causing consumer-typeset to miscompile. Perhaps more.

llvm-svn: 48035

Add support to APInt for shift and rotate operations with APInt
instead of uint32_t for the shift/rotate count operand type.

llvm-svn: 47741

Fixed bug in APInt::Profile() where the BitWidth field was not included in the
profile of the APSInt object. This caused unexpected Profile collisions where
none should have occurred.

llvm-svn: 47338

Fix a warning about comparison between signed and unsigned,
being consistent with the rest of the APInt implementation.

llvm-svn: 47138

Add countTrailingOnes member functions to APInt.

llvm-svn: 47086

Added FoldingSet style 'profiling' support for APInt.

llvm-svn: 46188

Remove attribution from file headers, per discussion on llvmdev.

llvm-svn: 45418

Cygwin defines uint32_t as unsigned long. Unbreak call to std::min in this case

llvm-svn: 45342

Don't have APInt.cpp depend upon DerivedTypes.h. This helps with splitting the
Support libraries separately into their own module.

llvm-svn: 44852

Fix PR1816, by correcting the broken definition of APInt::countTrailingZeros.

llvm-svn: 44296

Fix APInt::countTrailingZeros to return BitWidth if the input is zero instead of returning some random large number.

llvm-svn: 44294

Don't attempt to mask no bits

Add a new function tcExtract for extracting a bignum from an
arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

bit width instead of number of words allocated, which
makes it actually work for int->APF conversions.
Adjust callers. Add const to one of the APInt constructors
to prevent surprising match when called with const

Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

rename APInt::toString -> toStringUnsigned for symmetry with toStringSigned()

Add an APSInt::toString() method.

This adds a bunch of static functions that implement unsigned
two's complement bignum arithmetic. They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

Patch by Neil Booth!

Fix an assertion introduced by my last change to the toString method. We
can't use getZExtValue() to extract the low order bits for each digit.
Instead, we need to access the low order word directly.
