This enables users to export coverage information as portable JSON for use by
analysis tools and storage in document based databases.
The export sub-command is invoked just like the others:
llvm-cov export -instr-profile path/to/foo.profdata path/to/foo.binary
The resulting JSON contains a list of files and functions. Every file object
contains a list of segments, expansions, and a summary of the file's region,
function, and line coverage. Every function object contains the function's name
and regions. There is also a total summary for the entire object file.
Changes since the initial commit (r276813):
- Fixed the regexes in the tests to handle Windows filepaths.

Change the syntax to use `%0.sub8` to denote a subregister.
This seems like a more natural fit to denote subregisters; I also plan
to introduce a new ":classname" syntax in upcoming patches to denote the
register class of a vreg.
Note that this commit disallows plain identifiers to start with a '.'
character. This shouldn't affect anything as external names/IR
references are all prefixed with '$'/'%', plain identifiers are only
used for instruction names, register mask names and subreg indexes.

We already have code for ARM in initializeSections, so this

The kernel on Nexus 5X returns error_code in ucontext which has
correct FSR_WRITE flag, but empty (zero) abort type field. Removing
the checks means that we will report all SEGVs as READ on very old
kernels, but will properly distinguish READ vs WRITE on moderately
old ones.

We were just checking the public state, but that meant if you were hung in a long
running hand-called function, we wouldn't know to interrupt the process, and we would
not succeed in killing it.

Consider this case:
vreg1 = A2_zxth vreg0 (1)
...
vreg2 = A2_zxth vreg1 (2)
Redundant instruction elimination could delete the instruction (1)
because the user (2) only cares about the low 16 bits. Then it could
delete (2) because the input is already zero-extended. The problem
is that the properties allowing each individual instruction to be
deleted depend on the existence of the other instruction, so either
one can be deleted, but not both.
The existing check for this situation in RIE was insufficient. The
fix is to update all dependent cells when an instruction is removed
(replaced via COPY) in RIE.
llvm-svn: 276792
In an instruction like:
CFI_INSTRUCTION .cfi_def_cfa ...
we can drop the '.cfi_' prefix since that should be obvious by the
context:
CFI_INSTRUCTION def_cfa ...
While being a terser and cleaner syntax this also prepares to dropping
support for identifiers starting with a dot character so we can use it
for expressions.

This patch adds the CloneDetector class which allows searching source code
for clones.
For every statement or group of statements within a compound statement,
CloneDetector computes a hash value, and finds clones by detecting
identical hash values.
This initial patch only provides a simple hashing mechanism
that hashes the kind of each sub-statement.
This patch also adds CloneChecker - a simple static analyzer checker
that uses CloneDetector to report copy-pasted code.

Given similar reasons from r276710, ld64 scrubs DYLD_* environment if
called from the shim executable /usr/bin/ld.
Add support for finding ld64 via xcrun.
This is needed in order to get LIT to have the full path to the ld4
executable.

This test attempts to allocate 100 512MB aligned pages of memory. This
is implemented in the usual way by allocating size + alignment bytes and
aligning the result. As a result, this test allocates 51.2GB of memory.
Windows allocates swap for all memory allocated, and our bots do not
have this much swap available.
Avoid the failure by using a more reasonable alignment, like 16MB, as we
do on 32-bit.

In compare with what GNU linkers do (https://sourceware.org/binutils/docs/ld/Builtin-Functions.html),
this implementation simple:
Do not touch DATA_SEGMENT_ALIGN, it do what it do now - just aligns to the page boundary.
Parameters of DATA_SEGMENT_RELRO_END is ignored. That should be correct as it is usually just a 24 bytes
shift that allows to protect first 3 entries of got.plt with relro.
(https://svnweb.freebsd.org/base/head/sys/conf/ldscript.amd64?revision=284870&view=markup#l146).
DATA_SEGMENT_RELRO_END just aligns to the page boundary.
That is what expected because all sections that are not affected by relro should be on another memory page.
So at fact the difference with documented behavior is that we do not pad DATA_SEGMENT_ALIGN.
3 entries of got.plt are uncovered by relro, but functionality is simple and equal to lld behavior
for case when script is not given.
