This adds 'elf' as a recognized target triple environment value and overrides the default generated object format on Windows platforms if that value is present.  This patch also enables MCJIT tests on Windows using the new environment value.

APFloat::roundToIntegral: Special values don't keep the exponent value up to date, don't rely on it.

Add a couple of unit tests for special floats. Fixes 13929, found by MemorySanitizer.

For example, under a Linux chroot, /proc/ might not be mounted.
Therefor, we test if this file exist. If it is the case, use it (the current
behavior). Otherwise, we fall back to the detection used by *BSD.

The issue has been reported initially on the Debian bug tracker:

for libraries that don't need backtrace information on a crash.

This patch adds memory support functions which will later be used to implement section-specific protection handling in MCJIT.

* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
  people want -- it starts a new paragraph);
* use \param instead of \arg to document parameters in order to be consistent
  with the rest of the codebase.

Most of the code guarded with ANDROIDEABI are not
ARM-specific, and having no relation with arm-eabi.
Thus, it will be more natural to call this
environment "Android" instead of "ANDROIDEABI".

Note: We are not using ANDROID because several projects
are using "-DANDROID" as the conditional compilation
flag.

Tombstones and full hash collisions are rare, mark the "empty"
and "no collision" paths as likely. The bug in simplifycfg
that prevented the hints from being picked during selfhost
up was fixed recently :)

Adds the vendor 'fsl' (used by Freescale SDK) to Triple. This will allow
clang support for Freescale cross-compile configurations.

Fix undefined behavior (signed integer overflow) when Clang parses a hexfloat with an enormous exponent. Caught by an existing unit test + -ftrapv.

Reduce alignment of SmallVector<T> to the required amount, rather than forcing 16-byte alignment. This fixes misaligned SmallVector accesses via ExtractValueInst's SmallVector data member.

Fix a problem with APFloat::roundToIntegral where it would return incorrect results for negative inputs to trunc.  Add unit tests to verify this behavior.

Fix the construction of the magic constant for roundToIntegral to be 64-bit safe.  Fixes c-torture/execute/990826-0.c

llvm-svn: 161885

Add a roundToIntegral method to APFloat, which can be parameterized over various rounding modes.  Use this to implement SelectionDAG constant folding of FFLOOR, FCEIL, and FTRUNC.
