- * 2) Atomic operations, rather than explicit mutexes, are most commonly used
- * on code where contended operations are rate.
- *
- * To avoid needing a per-object lock, this code allocates an array of
- * locks and hashes the object pointers to find the one that it should use.

-//
-// The LLVM Compiler Infrastructure
-//
-// This file is dual licensed under the MIT and the University of Illinois Open
-// Source Licenses. See LICENSE.TXT for details.
-//
-//===----------------------------------------------------------------------===//
-//
-// This file implements a fairly generic conversion from a narrower to a wider
-// IEEE-754 floating-point type. The constants and types defined following the
-// includes below parameterize the conversion.
-//
-// This routine can be trivially adapted to support conversions from
-// half-precision or to quad-precision. It does not support types that don't
-// use the usual IEEE-754 interchange formats; specifically, some work would be
-// needed to adapt it to (for example) the Intel 80-bit format or PowerPC
-// double-double format.
-//
-// Note please, however, that this implementation is only intended to support
-// *widening* operations; if you need to convert to a *narrower* floating-point
-// type (e.g. double -> float), then this routine will not do what you want it
-// to.
-//
-// It also requires that integer types at least as large as both formats
-// are available on the target platform; this may pose a problem when trying
-// to add support for quad on some 32-bit systems, for example. You also may
-// run into trouble finding an appropriate CLZ function for wide source types;
-// you will likely need to roll your own on some platforms.
-//
-// Finally, the following assumptions are made:
-//
-// 1. floating-point types and integer types have the same endianness on the
-// target platform
-//
-// 2. quiet NaNs, if supported, are indicated by the leading bit of the
-// significand field being set
-//

-//===----------------------------------------------------------------------===//
-//
-// This file implements a fairly generic conversion from a wider to a narrower
-// IEEE-754 floating-point type in the default (round to nearest, ties to even)
-// rounding mode. The constants and types defined following the includes below
-// parameterize the conversion.
-//
-// This routine can be trivially adapted to support conversions to
-// half-precision or from quad-precision. It does not support types that don't
-// use the usual IEEE-754 interchange formats; specifically, some work would be
-// needed to adapt it to (for example) the Intel 80-bit format or PowerPC
-// double-double format.
-//
-// Note please, however, that this implementation is only intended to support
-// *narrowing* operations; if you need to convert to a *wider* floating-point
-// type (e.g. float -> double), then this routine will not do what you want it
-// to.
-//
-// It also requires that integer types at least as large as both formats
-// are available on the target platform; this may pose a problem when trying
-// to add support for quad on some 32-bit systems, for example.
-//
-// Finally, the following assumptions are made:
-//
-// 1. floating-point types and integer types have the same endianness on the
-// target platform
-//
-// 2. quiet NaNs, if supported, are indicated by the leading bit of the
-// significand field being set
