Dan Gohman 970d02c42d [WebAssembly] Initial linking metadata support
Add support for the new relocations and linking metadata section support in
https://github.com/WebAssembly/tool-conventions/blob/master/Linking.md. In
particular, this allows LLVM to indicate which variable is the stack pointer,
so that it can be linked with other objects.

This also adds support for emitting type relocations for call_indirect
instructions.

Right now, this is mainly tested by using wabt and hexdump to examine the
output on selected testcases. We'll add more tests as the design stablizes
and more of the pieces are in place.

Rafael Espindola 1eee6eda0e Use os.path.realpath when tracking the cwd.
This is needed by TestCases/Posix/coverage-direct.cc

The problem is that the test does:

mkdir <dir>
cd <dir>
cd ..
rm -rf <dir>
<more commands>

the current directory currently looks like "/.../<dir>/../" which
doesn't exist when dir is deleted.

at some point we should probably switch to using the os current
directory (specially if we want to add subshell), but this is a small
incremental improvement.

Kamil Rytarowski 3eef2b5e96 Battery of NetBSD support improvements
Summary:
Include initial support for:
 - single step mode (PT_STEP)
 - single step trap handling (TRAP_TRACE)
 - exec() trap (TRAP_EXEC)
 - add placeholder interfaces for FPR
 - initial code for NetBSD core(5) files
 - minor tweaks

While there improve style of altered elf-core/ files.

This code raises the number of passing tests on NetBSD to around 50% (600+/1200+).

The introduced code is subject to improve afterwards for additional features and bug fixes.

Yaron Keren 9d27c47b46 Following r297661, disable dup workaround to disable duplicate STDOUT fd closing and instead directly prevent closing of STD* file descriptors.
We do not want to close STDOUT as there may have been several uses of it
such as the case: llc %s -o=- -pass-remarks-output=- -filetype=asm
which cause multiple closes of STDOUT_FILENO and/or use-after-close of it.
Using dup() in getFD doesn't work as we end up with original STDOUT_FILENO
open anyhow.

Adam Nemet edaec6de73 [DAGCombiner] Initial support for the fast-math flag contract
Now alternatively to the TargetOption.AllowFPOpFusion global flag, FMUL->FADD
can also use the per operation FMF to allow fusion.

The idea here is not to port everything to the new scheme (e.g. fused
multiply-and-sub will be ported later) but that this work all the way from
clang.

The transformation is conditionalized on *both* the FADD and the FMUL having
the FMF contract flag.

Ahmed Bougacha 6dd6082472 [CodeGen] Pass SDAG an ORE, and replace FastISel stats with remarks.
In the long-term, we want to replace statistics with something
finer-grained that lets us gather per-function data.
Remarks are that replacement.

Create an ORE instance in SelectionDAGISel, and pass it to
SelectionDAG.

SelectionDAG was used so that we can emit remarks from all
SelectionDAG-related code, including TargetLowering and DAGCombiner.
This isn't used in the current patch but Adam tells me he's interested
for the fp-contract combines.

Use the ORE instance to emit FastISel failures as remarks (instead of
the mix of dbgs() dumps and statistics that we currently have).

Eventually, we want to have an API that tells us whether remarks are
enabled (http://llvm.org/PR32352) so that we don't emit expensive
remarks (in this case, dumping IR) when it's not needed.  For now, use
'isEnabled' as a crude replacement.

This does mean that the replacement for '-fast-isel-verbose' is now
'-pass-remarks-missed=isel'.  Additionally, clang users also need to
enable remark diagnostics, using '-Rpass-missed=isel'.

This also removes '-fast-isel-verbose2': there are no static statistics
that we want to only enable in asserts builds, so we can always use
the remarks regardless of the build type.
