Hans Wennborg f6892eda24 [CMake] don't build libLTO when LLVM_ENABLE_PIC is OFF
When cmake is run with -DLLVM_ENABLE_PIC=OFF, build fails while

with -fno-PIC. More details here: https://llvm.org/bugs/show_bug.cgi?id=26484.
This diff reverts r252652 (git 9fd4377ddb83aee3c049dc8757e7771edbb8ee71),

Mike Aizatsky 95149921b2 [sancov] improved object files handling.
Multi-dso programs result in multiple coverage files dumped of the form
'<module_name>.<pid>.sancov'. When analyzing these coverage files it is
important to use correct corresponding object file.

This change removes the "-obj" sancov flag and lets user specify object
file names alongside coverage files. Sancov tool would match them using
<module_name> part of coverage file and short file name of the object
file.

Quentin Colombet bde158cbc7 [CMake] Produce an empty library for GlobalISel when not building it.
The rational for this change is that LLVMBuild cannot express conditional 
dependencies. Therefore, when we start optionally using GlobalISel library for 
say AArch64, without that change, all the tools that use the AArch64 library 
would need to explicitly link with GlobalISel when we ask for it.

This does not scale.

Instead, we will set the dependencies between the target and GlobalISel and if 
we did not ask to build GlobalISel, the library will just be empty.

Thanks to Chris Bieneman and Mehdi Animi for the idea.

Teresa Johnson e1164de5d0 Restore "[ThinLTO] Use MD5 hash in function index." with fix
This restores commit r260408, along with a fix for a bot failure.

The bot failure was caused by dereferencing a unique_ptr in the same
call instruction parameter list where it was passed via std::move.
Apparently due to luck this was not exposed when I built the compiler
with clang, only with gcc.

Teresa Johnson 0919a84071 [ThinLTO] Use MD5 hash in function index.
Summary:
This patch uses the lower 64-bits of the MD5 hash of a function name as
a GUID in the function index, instead of storing function names. Any
local functions are first given a global name by prepending the original
source file name. This is the same naming scheme and GUID used by PGO in
the indexed profile format.

This change has a couple of benefits. The primary benefit is size
reduction in the combined index file, for example 483.xalancbmk's
combined index file was reduced by around 70%. It should also result in
memory savings for the index file in memory, as the in-memory map is
also indexed by the hash instead of the string.

Second, this enables integration with indirect call promotion, since the
indirect call profile targets are recorded using the same global naming
convention and hash. This will enable the function importer to easily
locate function summaries for indirect call profile targets to enable
their import and subsequent promotion.

The original source file name is recorded in the bitcode in a new
module-level record for use in the ThinLTO backend pipeline.

Rong Xu 33c76c0cc2 [PGO] Differentiate Clang instrumentation and IR level instrumentation profiles
This patch uses one bit in profile version to differentiate Clang
instrumentation and IR level instrumentation profiles.

PGOInstrumenation generates a COMDAT variable __llvm_profile_raw_version so
that the compiler runtime can set the right profile kind.
For Maco-O platform, we generate the variable as linkonce_odr linkage as
COMDAT is not supported.

PGOInstrumenation now checks this bit to make sure it's an IR level
instrumentation profile.

The patch was submitted as r260164 but reverted due to a Darwin test breakage.

This basically add an echo test case in C. The support is limited right now, but full support would just be too much to review at once.

The echo test case simply get a module as input and try to output the same exact module. This allow to check the both reading and writing API are working as expected.

I want to improve this test over time to support more and more of the API, in order to improve coverage (coverage is quite poor right now).

Test Plan: Run the test.

Reid Kleckner 1fcd610c94 [codeview] Wire up the .cv_inline_linetable directive
This directive emits the binary annotations that describe line and code
deltas in inlined call sites. Single-stepping through inlined frames in
windbg now works.

Frederic Riss 1d53658eae [dsymutil] Skip mach-o paired relocations
Noticed while working on scattered relocations.
I do not think these relocs can actually happen in the debug_info section,
but if they happen the code would mishandle them. Explicitely skip them
and warn if we encounter one.

Frederic Riss 0314e1e1ef [dsymutil] Support scattered relocs.
Although it seems like clang will never emit scattered relocations in
the debug information (at least I couldn't find a way), we have too
support them for the benefit of other compilers.
As clang doesn't generate them, the included testcase was produced
from hacked up assembly.

Frederic Riss 6c8521ad32 [dsymutil] Fix handling of common symbols.
llvm-dsymutil was misinterpreting the value of common symbols as their
address when it actually contains their size. This didn't impact
llvm-dsymutil's ability to link the debug information for common symbols
because these are always found by name and not by address. Things could
however go wrong when the size of a common object matched the object
file address of another symbol. Depending on the link order of the symbols
the common object might incorrectly evict this other object from the
address to symbol mapping, and then link the evicted symbol with a wrong
binary address.

Use the new ability to have symbols without an object file address to fix
this.

Frederic Riss d8c33dc2f6 [dsymutil] Allow debug map mappings with no object file address. NFC
This change just changes the data structure that ties symbol names,
object file address and linked binary addresses to accept mappings
with no object file address. Such symbol mappings are not fed into
the debug map yet, so this patch is NFC.
A subsequent patch will make use of this functionality for common
symbols.

Reid Kleckner c62e379d22 [CodeView] Use assembler directives for line tables
Adds a new family of .cv_* directives to LLVM's variant of GAS syntax:

- .cv_file: Similar to DWARF .file directives

- .cv_loc: Similar to the DWARF .loc directive, but starts with a
  function id. CodeView line tables are emitted by function instead of
  by compilation unit, so we needed an extra field to communicate this.
  Rather than overloading the .loc direction further, we decided it was
  better to have our own directive.

- .cv_stringtable: Emits the codeview string table at the current
  position. Currently this just contains the filenames as
  null-terminated strings.

- .cv_filechecksums: Emits the file checksum table for all files used
  with .cv_file so far. There is currently no support for emitting
  actual checksums, just filenames.

This moves the line table emission code down into the assembler.  This
is in preparation for implementing the inlined call site line table
format. The inline line table format encoding algorithm requires knowing
the absolute code offsets, so it must run after the assembler has laid
out the code.

David Majnemer collaborated on this patch.
