Mehdi Amini ef156c6701 Add missing error handling in llvm-lto
Annoyingly, ErrorOr allows to *not check* the error when things go
well. It will crash badly when there is an error though. It should
runtime assert when it is used without being checked!

Lang Hames 1b640e05ba [MachO] Add MachO alt-entry directive support.
This patch adds support for the MachO .alt_entry assembly directive, and uses
it for global aliases with non-zero GEP offsets. The alt_entry flag indicates
that a symbol should be layed out immediately after the preceding symbol.
Conceptually it introduces an alternate entry point for a function or data
structure. E.g.:

safe_foo:
  // check preconditions for foo
.alt_entry fast_foo
fast_foo:
  // body of foo, can assume preconditions.

The .alt_entry flag is also implicitly set on assembly aliases of the form:

a = b + C

where C is a non-zero constant, since these have the same effect as an
alt_entry symbol: they introduce a label that cannot be moved relative to the
preceding one. Setting the alt_entry flag on aliases of this form fixes
http://llvm.org/PR25381.

Teresa Johnson 26ab5772b0 [ThinLTO] Renaming of function index to module summary index (NFC)
(Resubmitting after fixing missing file issue)

With the changes in r263275, there are now more than just functions in
the summary. Completed the renaming of data structures (started in
r263275) to reflect the wider scope. In particular, changed the
FunctionIndex* data structures to ModuleIndex*, and renamed related
variables and comments. Also renamed the files to reflect the changes.

A companion clang patch will immediately succeed this patch to reflect
this renaming.

Justin Bogner 2414c5d46b llvm-shlib: Remove the option to override __cxa_atexit
If anybody is actually using this, it probably doesn't do what they
think it does. This actually causes the dylib to *export* a
__cxa_atexit symbol, so anything that links it probably loses their
exit time destructors as well as disabling LLVM's.

This just removes the option entirely. If somebody does need this
behaviour we should figure out a more principled way to do it.

This is effectively a revert of r223805.

Teresa Johnson 76a1c1d0ba [ThinLTO] Support for reference graph in per-module and combined summary.
Summary:
This patch adds support for including a full reference graph including
call graph edges and other GV references in the summary.

The reference graph edges can be used to make importing decisions
without materializing any source modules, can be used in the plugin
to make file staging decisions for distributed build systems, and is
expected to have other uses.

The call graph edges are recorded in each function summary in the
bitcode via a list of <CalleeValueIds, StaticCount> tuples when no PGO
data exists, or <CalleeValueId, StaticCount, ProfileCount> pairs when
there is PGO, where the ValueId can be mapped to the function GUID via
the ValueSymbolTable. In the function index in memory, the call graph
edges reference the target via the CalleeGUID instead of the
CalleeValueId.

The reference graph edges are recorded in each summary record with a
list of referenced value IDs, which can be mapped to value GUID via the
ValueSymbolTable.

Addtionally, a new summary record type is added to record references
from global variable initializers. A number of bitcode records and data
structures have been renamed to reflect the newly expanded scope of the
summary beyond functions. More cleanup will follow.

Chandler Carruth b47f8010a9 [PM] Make the AnalysisManager parameter to run methods a reference.
This was originally a pointer to support pass managers which didn't use
AnalysisManagers. However, that doesn't realistically come up much and
the complexity of supporting it doesn't really make sense.

In fact, *many* parts of the pass manager were just assuming the pointer
was never null already. This at least makes it much more explicit and

Evgeniy Stepanov 4dc3c8df45 [gold] Fix common symbols handling.
LLVM Gold plugin decides which instance of a common symbol it wants

up with an undefined reference.

Mehdi Amini 09b4a8daa3 Add a flag to the LLVMContext to disable name for Value other than GlobalValue
Summary:
This is intended to be a performance flag, on the same level as clang
cc1 option "--disable-free". LLVM will never initialize it by default,
it will be up to the client creating the LLVMContext to request this
behavior. Clang will do it by default in Release build (just like
--disable-free).

"opt" and "llc" can opt-in using -disable-named-value command line
option.

When performing LTO on llvm-tblgen, the initial merging of IR peaks
at 92MB without this patch, and 86MB after this patch,setNameImpl()
drops from 6.5MB to 0.5MB.
The total link time goes from ~29.5s to ~27.8s.

Compared to a compile-time flag (like the IRBuilder one), it performs
very close. I profiled on SROA and obtain these results:

 420ms with IRBuilder that preserve name
 372ms with IRBuilder that strip name
 375ms with IRBuilder that preserve name, and a runtime flag to strip

The intent of this patch is to provide a first implementation as a

definiing the libLTO C API. Some part of the libLTO API are left
unimplemented yet. Following patches will add support for these.

Teresa Johnson a17f2cd1a3 [ThinLTO] Ensure prevailing linkonce emitted as weak in ThinLTO backends
Summary:
Since IR files are all compiled into separate independent object files
in ThinLTO mode, the prevailing linkonce symbols must be emitted in its
object file even if it is no longer referenced there, e.g. if no
references remain in the module after inlining, since it may be
referenced by another ThinLTO compiled object file. This is done by
changing LDPR_PREVAILING_DEF_IRONLY* symbols to LDPR_PREVAILING_DEF,
which converts the prevailing linkonce to weak. We also don't need the
other prevailing IRONLY handling for internalization, which is not
currently performed for ThinLTO.

Test case included.

Teresa Johnson 7cffaf3ad0 [ThinLTO] Launch importing backends in parallel threads from gold plugin
Summary:
Launch ThinLTO backends (LTO and codegen pipelines with importing) in
parallel using a ThreadPool, after creating the combined index.
The number of threads is controlled by the existing -jobs gold plugin
option, or the hardware concurrency if not specified.

The old behavior of exiting after creating the combined index can be
invoked via a new thinlto-index-only plugin option.

Petr Pavlu 7ad9ec9fcf [LTO] Fix error reporting from lto_module_create_in_local_context()
Function lto_module_create_in_local_context() would previously
rely on the default LLVMContext being created for it by
LTOModule::makeLTOModule(). This context exits the program on
error and is not arranged to update sLastStringError in
tools/lto/lto.cpp.

Function lto_module_create_in_local_context() now creates an
LLVMContext by itself, sets it up correctly to its needs and then
passes it to LTOModule::createInLocalContext() which takes
ownership of the context and keeps it present for the lifetime of
the returned LTOModule.

Function LTOModule::makeLTOModule() is modified to take a
reference to LLVMContext (instead of a pointer) and no longer
creates a default context when nullptr is passed to it. Method
LTOModule::createInContext() that takes a pointer to LLVMContext
is removed because it allows to pass a nullptr to it. Instead
LTOModule::createFromBuffer() (that takes a reference to
LLVMContext) should be used.

Figured this would be a problem, but didn't want to jump the gun - large

well do the same for CUs too). A random sample 6m27s -> 27s change.

Also, by checking this up-front for CUs (rather than when building the
cu_index) we can probably provide better error messages (see FIXMEs),
hopefully providing the name of the CUs rather than just their

Chandler Carruth edf5996b06 [PM/AA] Teach the new pass manager to use pass-by-lambda for registering
analysis passes, support pre-registering analyses, and use that to
implement parsing and pre-registering a custom alias analysis pipeline.

With this its possible to configure the particular alias analysis
pipeline used by the AAManager from the commandline of opt. I've updated
the test to show this effectively in use to build a pipeline including
basic-aa as part of it.

My big question for reviewers are around the APIs that are used to
expose this functionality. Are folks happy with pass-by-lambda to do
pass registration? Are folks happy with pre-registering analyses as
a way to inject customized instances of an analysis while still using
the registry for the general case?

Other thoughts of course welcome. The next round of patches will be to
add the rest of the alias analyses into the new pass manager and wire
them up here so that they can be used from opt. This will require
extending the (somewhate limited) functionality of AAManager w.r.t.
module passes.

Rafael Espindola e17c3f3ee7 Represent the dynamic table itself with a DynRegionInfo.
The dynamic table is also an array of a fixed structure, so it can be
represented with a DynReginoInfo.

existing tests with a broken dynamic program header.

Rafael Espindola ce2fbddd19 Change how readobj stores info about dynamic symbols.
We used to keep both a section and a pointer to the first symbol.

The oddity of keeping a section for dynamic symbols is because there is
a DT_SYMTAB but no DT_SYMTABZ, so to print the table we have to find the
size via a section table.

The reason for still keeping a pointer to the first symbol is because we
want to be able to print relocation tables even if the section table is
missing (it is mandatory only for files used in linking).

With this patch we keep just a DynRegionInfo. This then requires
changing a few places that were asking for a Elf_Shdr but actually just
needed the first symbol.

The test change is to delete the program header pointer.
Now that we use the information of both DT_SYMTAB and .dynsym, we don't
depend on the sh_entsize of .dynsym if we see DT_SYMTAB.

Note: It is questionable if it is worth it putting the effort to report
broken sh_entsize given that in files with no section table we have to
assume it is sizeof(Elf_Sym), but that is for another change.

Extracted from r260488.

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 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.

Simon Atanasyan cb1175c7db [llvm-readobj][ELF] Show MIPS GOT content when there is another zero-sized section at the same address
It is possible to have .got section and one or more zero-sized section
at the same address. This patch first checks that GOT (or GOT PLT)
section should have non-zero size using corresponding dynamic tags. Then
it looks up not empty section at the specified address.

Rong Xu 1288a19421 [PGO] Differentiate Clang instrumentation and IR level instrumentation profiles
This patch uses one bit in profile version to differentiate Clang

PGOInstrumenation generates a COMDAT variable __llvm_profile_raw_version so
that the compiler runtime can set the right profile kind.
PGOInstrumenation now checks this bit to make sure it's an IR level
instrumentation profile.

Amaury Sechet e8ea7d8b1d Improve testing for the C API
Summary:
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.

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.

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.

Petr Pavlu eba3039238 [LTO] Fix error reporting when a file passed to libLTO is invalid or non-existent
This addresses PR26060 where function lto_module_create() could return nullptr
but lto_get_error_message() returned an empty string.

The error() call after LTOModule::createFromFile() in llvm-lto is then removed
because any error from this function should go through the diagnostic handler in
llvm-lto which will exit the program. The error() call was added because this
previously did not happen when the file was non-existent. This is fixed by the
patch. (The situation that llvm-lto reports an error when the input file does
not exist is tested by llvm/tools/llvm-lto/error.ll).

Andrew Wilkins dfd6088c3f tools/llvm-config: improve shared library support
Summary:

This is a re-commit of r257003, which was reverted,
along with the fixes from http://reviews.llvm.org/D15986.

r252532 added support for reporting the monolithic library
when LLVM_BUILD_LLVM_DYLIB is used. This would only be done
if the individual components were not found, and the dynamic
library is found.

This diff extends this as follows:
 - If LLVM_LINK_LLVM_DYLIB is set, then prefer the shared
   library, even if all component libraries exist.
 - Two flags, --link-shared and --link-static are introduced
   to provide explicit guidance. If --link-shared is passed
   and the shared library does not exist, an error results.

Additionally, changed the expected shared library names from
(e.g.) LLVM-3.8.0 to LLVM-3.8. The former exists only in an
installation (and then only in CMake builds I think?), and not
in the build tree; this breaks usage of llvm-config during
builds, e.g. by llvm-go.

Sergei Larin d19d4d30d8 Add to the split module utility an SCC based method which allows not to globalize any local variables.
Summary:
    Currently llvm::SplitModule as the first step globalizes all local objects, which might not be desirable in some scenarios.
    This change adds a new flag to llvm::SplitModule that uses SCC approach to search for a balanced partition without the need to externalize symbols.
    Such partition might not be possible or fully balanced for a given number of partitions, and is a function of the module properties (global/local dependencies within the module).
    
    Joint development Tobias Edler von Koch (tobias@codeaurora.org) and Sergei Larin (slarin@codeaurora.org)

Rafael Espindola 257a35368f Bring back "Assert that we have all use/users in the getters."
This reverts commit r257751, bringing back r256105.

The problem the assert found was fixed in r257915.

Original commit message:

Assert that we have all use/users in the getters.

An error that is pretty easy to make is to use the lazy bitcode reader
and then do something like

if (V.use_empty())

The problem is that uses in unmaterialized functions are not accounted
for.

This patch adds asserts that all uses are known.

Binary annotations are encoded along the lines of UTF-8 and ECI but with

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.

Davide Italiano 25d84580f4 [llvm-readobj] Remove dead code. Add an assertion instead.
When we arrive at the end of the function, the validation of
the object has been done already. In theory, so, we should never
arrive here with something broken as the object isn't mutated.
Practice sometimes proves theory to be wrong, so leave an assertion
instead, as suggested by David Blaikie, to catch bugs.

Kevin Enderby 0ae163f9ea For llvm-objdump, add the option -private-header (without the trailing ’s’)
to only print the first private header.

Which for Mach-O files only prints the Mach header and not the subsequent load
commands.  Which is used by scripts to match what the darwin otool(1) with the
-h flag does without the -l flag.

For non-Mach-O files it has the same functionality as -private-headers (with
the trailing ’s’).
