Reid Kleckner 2893fd18af [codeview] Print relocations against code and data offset fields
These fields are almost always zero. However, there are relocations
against them, and we should print the relocation symbol with it as
SYM+0xNN.

James Molloy a9497f53c9 [ValueTracking] Understand more select patterns in ComputeKnownBits
Some patterns of select+compare allow us to know exactly the value of the uppermost bits in the select result. For example:

  %b = icmp ugt i32 %a, 5
  %c = select i1 %b, i32 2, i32 %a

Here we know that %c is bounded by 5, and therefore KnownZero = ~APInt(5).getActiveBits() = ~7.

There are several such patterns, and this patch attempts to understand a reasonable subset of them - namely when the base values are the same (as above), and when they are related by a simple (add nsw), for example (add nsw %a, 4) and %a.

Dan Liew ee419bedc4 [docs] Improve the documentation on committing code reviewed on
Phabricator to trunk.

The previous documentation had a few issues:

* It did not make it explicit that code could be
committed without using the Arcanist tool and how this should be done.

* There was also an implicit assumption on using Subversion
rather than git-svn in the example using Arcanist. The documentation now
explicitly mentions both cases and details how to commit to trunk in
each case.

Kuba Brecka 0626dd0d3b [tsan] Introduce a "ignore_interceptors_accesses" option
On OS X, TSan already passes all unit and lit tests, but for real-world applications (even very simple ones), we currently produce a lot of false positive reports about data races. This makes TSan useless at this point, because the noise dominates real bugs. This introduces a runtime flag, "ignore_interceptors_accesses", off by default, which makes TSan ignore all memory accesses that happen from interceptors. This will significantly lower the coverage and miss a lot of bugs, but it eliminates most of the current false positives on OS X.

George Rimar 28f4fbe480 [ELF] - implemented --eh-frame-hdr command line option.
--eh-frame-hdr
Request creation of ".eh_frame_hdr" section and ELF "PT_GNU_EH_FRAME" segment header.

Both gold and the GNU linker support an option --eh-frame-hdr which tell them to construct a header for all the .eh_frame sections. This header is placed in a section named .eh_frame_hdr and also in a PT_GNU_EH_FRAME segment. At runtime the unwinder can find all the PT_GNU_EH_FRAME segments by calling dl_iterate_phdr.
This section contains a lookup table for quick binary search of FDEs.

Vaivaswatha Nagaraj 68befd7094 [GlobalsAA] Relax condition in checking globals as args to functions
Summary:
Since globals may escape as function arguments (even when they have been 
found to be non-escaping, because of optimizations such as memcpyoptimizer
that replaces stores with memcpy), all arguments to a function are checked
during query to make sure they are identifiable. At that time, also ensure
we return a conservative result only if the arguments don't alias to our global.

Binary annotations are encoded along the lines of UTF-8 and ECI but with
a few minor differences.

The algorithm specified in "ECMA-335 CLI Section II.3.2 - Blobs and
Signatures" is used to compress binary annotations.  Signed binary
annotations are encoded like unsigned annotations except the sign bit is
rotated left to reduce the number of bits needed to be encoded.

David Majnemer 3463e696fb [X86] Don't alter HasOpaqueSPAdjustment after we've relied on it
We rely on HasOpaqueSPAdjustment not changing after we've calculated
things based on it.  Things like whether or not we can use 'rep;movs' to
copy bytes around, that sort of thing.  If it changes, invariants in the
backend will quietly break.  This situation arose when we had a call to
memcpy *and* a COPY of the FLAGS register where we would attempt to
reference local variables using %esi, a register that was clobbered by
the 'rep;movs'.

This fixes PR26124.
