Rafael Espindola 58873566b3 Make the llvm mangler depend only on DataLayout.
Before this patch any program that wanted to know the final symbol name of a
GlobalValue had to link with Target.

This patch implements a compromise solution where the mangler uses DataLayout.
This way, any tool that already links with Target (llc, clang) gets the exact
behavior as before and new IR files can be mangled without linking with Target.

With this patch the mangler is constructed with just a DataLayout and DataLayout
is extended to include the information the Mangler needs.

Rafael Espindola 6994fdf33c Remove the 's' DataLayout specification
During the years there have been some attempts at figuring out how to
align byval arguments. A look at the commit log suggests that they
were

* Use the ABI alignment.
* When that was not sufficient for x86-64, I added the 's' specification to
  DataLayout.
* When that was not sufficient Evan added the virtual getByValTypeAlignment.
* When even that was not sufficient, we just got the FE to add the alignment
  to the byval.

This patch is just a simple cleanup that removes my first attempt at fixing the
problem. I also added an AArch64 implementation of getByValTypeAlignment to
make sure this patch is a nop. I also left the 's' parsing for backward
compatibility.

I will send a short email to llvmdev about the change for anyone maintaining
an out of tree target.

Reid Kleckner a534a38130 Begin adding docs and IR-level support for the inalloca attribute
The inalloca attribute is designed to support passing C++ objects by
value in the Microsoft C++ ABI.  It behaves the same as byval, except
that it always implies that the argument is in memory and that the bytes
are never copied.  This attribute allows the caller to take the address
of an outgoing argument's memory and execute arbitrary code to store
into it.

This patch adds basic IR support, docs, and verification.  It does not
attempt to implement any lowering or fix any possibly broken transforms.

When this patch lands, a complete description of this feature should
appear at http://llvm.org/docs/InAlloca.html .

Arnaud A. de Grandmaison b697b538dc CMake : optionaly enable LLVM to be compiled with -std=c++11 (default: off)
In some case, it may be required to build LLVM in C++11 mode, as some the subprojects (like lldb) requires it.

This mimics the autoconf behaviour.

However, given the discussions on the switch to C++11 of the codebase, this behaviour should evolve to default to C++11 with some checks of the compiler capabilities.

Rafael Espindola 60ec3836a2 Support multiple COFF sections with the same name but different COMDAT.
This is the first step to fix pr17918.

It extends the .section directive a bit, inspired by what the ELF one looks
like. The problem with using linkonce is that given

.section foo
.linkonce....

.section foo
.linkonce

we would already have switched sections when getting to .linkonce. The cleanest
solution seems to be to add the comdat information in the .section itself.

Hans Wennborg fc59812bee CMake: make building with /MT an option instead of always forcing it

This is a follow-up to r194589. Aaron pointed out that building
libraries with /MT and using them in an application that uses a
different run-time library can be a bad idea.

Move the option to build with /MT behind a CMake option so it can be
turned on selectively, such as when building the toolchain installer.

Rafael Espindola 716e7405d3 Remove linkonce_odr_auto_hide.
linkonce_odr_auto_hide was in incomplete attempt to implement a way
for the linker to hide symbols that are known to be available in every
TU and whose addresses are not relevant for a particular DSO.

It was redundant in that it all its uses are equivalent to
linkonce_odr+unnamed_addr. Unlike those, it has never been connected
to clang or llvm's optimizers, so it was effectively dead.

Given that nothing produces it, this patch just nukes it
(other than the llvm-c enum value).

Chandler Carruth baf3fdb86b Nuke the hilariously out of date suggestion to unpack llvm-gcc 4.2 as
part of getting started with LLVM.

The LLVM getting started document is in woeful need of attention. I may
get to some of this, but some random notes for folks interested:

1) We need to separate the getting started steps for folks who are
   interested in the core LLVM libs and nothing else, folks interested
   in a nifty C++ toolchain and nothing else, and folks interested in
   both.
2) We should include documentation for both release archives, svn, and
   git in equal portion, and we should document all of the various
   repositories of interest: llvm, clang, clang-tools-extra,
   compiler-rt, lld, libcxx, test-suite.
3) We should document the CMake build. We should probably document the
   CMake build first, and give a fall-back set of docs for the Makefile
   build for the use cases where that is still the preferred solution.
   This would more closely match the use cases that folks in the open
   source community are likely to have, and would remove a point of
   discrepancy between Linux, Windows, and Mac instructions.
4) Probably a ton of other modernization stuff that I've not thought of
   here.

Anyways, if anyone at all is interested, please help clean up this
document. It is much needed.

Hal Finkel 0c5c01aa4a Add a llvm.copysign intrinsic
This adds a llvm.copysign intrinsic; We already have Libfunc recognition for
copysign (which is turned into the FCOPYSIGN SDAG node). In order to
autovectorize calls to copysign in the loop vectorizer, we need a corresponding
intrinsic as well.

In addition to the expected changes to the language reference, the loop
vectorizer, BasicTTI, and the SDAG builder (the intrinsic is transformed into
an FCOPYSIGN node, just like the function call), this also adds FCOPYSIGN to a
few lists in LegalizeVector{Ops,Types} so that vector copysigns can be
expanded.

In TargetLoweringBase::initActions, I've made the default action for FCOPYSIGN
be Expand for vector types. This seems correct for all in-tree targets, and I
think is the right thing to do because, previously, there was no way to generate
vector-values FCOPYSIGN nodes (and most targets don't specify an action for
vector-typed FCOPYSIGN).

Hal Finkel 171817ee8a Add ISD::FROUND for libm round()
All libm floating-point rounding functions, except for round(), had their own
ISD nodes. Recent PowerPC cores have an instruction for round(), and so here I'm
adding ISD::FROUND so that round() can be custom lowered as well.

For the most part, this is straightforward. I've added an intrinsic
and a matching ISD node just like those for nearbyint() and friends. The
SelectionDAG pattern I've named frnd (because ISD::FP_ROUND has already claimed
fround).

This will be used by the PowerPC backend in a follow-up commit.

Rafael Espindola 2a2a0973b8 Use pipefail when available.
This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.
