This will be used in the sanitizer test suite, which wants to use DWARF
line tables.
At some point we should reconsider how LLD handles the long section
names required by DWARF debug sections.

Summary:
Adding a printer pass for printing the LVI cache values after transformations
that use LVI.
This will help us in identifying cases where LVI
invariants are violated, or transforms that leave LVI in an incorrect state.
Right now, I have added two test cases to show that the printer pass is working.
I will be adding more test cases in a later change, once this change is
checked in upstream.

This #include was the cause of a dependency from Symbol ->
DataFormatters. However, nothing from the header was being
used anyway, so we can just remove it with no adverse effects.
This reduces the overall cycle count from 44 to 43.

It seems MS headers have started using __readgsqword, and since it's
used in a header that doesn't include intrin.h, we can't implement it as
an inline function anymore.
That was already the case for __readfsdword, which Saleem added support
for in r220859. This patch reuses that codegen to implement all of
__read[fg]s{byte,word,dword,qword}.

Summary:
This patch is the first step towards allows us to move away from using
__thread for the allocator cache on darwin,
which is requiring for building lsan for darwin on ios version 7
and on iossim i386.
This will be followed by patches to move the function into OS-specific files.

We currently display a list of all minimal cycles, but it's
useful to be able to see the big picture impact of these cycles
by merging them all together into groups of interconnected
components.
Because the cycle discovery algorithm only considers "minimal"
cycles, it discards all information for dependencies which are
not considered part of the minimal cycle. So all we know is that
the components of each island definitely all depend on each other
but it's still possible that there are hidden dependencies due
to transitive includes.
The cycle list should still be the authoritative reference for
deciding where the easiest places to break cycles are, though.

The isl C++ bindings now has implicit conversions from isl::set to
isl::union_set. Therefore the additional overload accepting isl::set
is not required anymore.

This was causing a test failure in one of LLDB's tests which
specifically dealt with a limitation in LLVM's implementation
of home_directory() that LLDB's own implementation had worked
around.
This limitation has been addressed in r298513 on the LLVM side,
so the failing test (which is now unnecessary as the limitation
no longer exists) was removed in r298519, allowing this patch to
be re-submitted without modification.

Summary: Currently, we build the compiler-rt runtimes with link-time optimization if LTO is configured for the LLVM project. This will break external programs that don't invoke the linker in such a way that it supports LLVM's LTO. To avoid this, this change causes the compiler-rt runtimes to be compiled with -fno-lto. This also makes the check-profile tests work on systems when doing a lld LTO build on a system where the system linker does not support LLVM LTO.

As noted in the code comment and seen in the test changes, the motivation is that by pulling
constant insertion up, we may be able to constant fold some insertelement instructions.

This was added to workaround a limitation in LLVM's implementation
of getting the current user's home directory, since it would
only look at the value of $HOME, but we did not want to rely
on that being set so we would also look in the password database.
Adding the ability to look in the password database to LLVM was
a straightforward patch that was submitted in r298513, so since
that is done this test is no longer needed.
llvm-svn: 298519
Also add an assertion for the case that there are multiple FI
expressions with a DW_OP_LLVM_fragment; which should violate internal
constraints in DbgVariable.
llvm-svn: 298518
It's possible (albeit strange) for $HOME to intentionally
point somewhere other than the user's home directory as
reported by the password database. Our test shouldn't fail
in this case. This patch updates the test to pull directly
from the password database before unsetting $HOME, rather
than comparing the return value of home_directory() to the
original value of the environment variable.
llvm-svn: 298514
This is something of an edge case, but when the $HOME environment
variable is not set, we can still look in the password database
to get the current user's home directory.
Added a test for this by getting the value of $HOME, then unsetting
it, then calling home_directory() and verifying that it succeeds
and that the value is the same as what we originally read from
the environment.

Introduce another level of alias metadata to distinguish the individual
non-aliasing accesses that have inter iteration alias-free base pointers
marked with "Inter iteration alias-free" mark nodes. It can be used to,
for example, distinguish different stores (loads) produced by unrolling of
the innermost loops and, subsequently, sink (hoist) them by LICM.
