Kevin Enderby 49b4f53cad Tweak llvm-nm’s -undefined-only (aka -u) printing for Mach-O files
to just print the symbol name.  So it matches darwin’s nm(1) -u option.

Duncan P. N. Exon Smith 1f66c856b5 Bitcode: Serialize (and recover) use-list order
Predict and serialize use-list order in bitcode.  This makes the option
`-preserve-bc-use-list-order` work *most* of the time, but this is still
experimental.

  - Builds a full value-table up front in the writer, sets up a list of
    use-list orders to write out, and discards the table.  This is a
    simpler first step than determining the order from the various
    overlapping IDs of values on-the-fly.

  - The shuffles stored in the use-list order list have an unnecessarily
    large memory footprint.

  - `blockaddress` expressions cause functions to be materialized
    out-of-order.  For now I've ignored this problem, so use-list orders
    will be wrong for constants used by functions that have block
    addresses taken.  There are a couple of ways to fix this, but I
    don't have a concrete plan yet.

  - When materializing functions lazily, the use-lists for constants
    will not be correct.  This use case is out of scope: what should the
    use-list order be, if it's incomplete?

Duncan P. N. Exon Smith 4b4d8ecde1 Move -verify-use-list-order into llvm-uselistorder
Ugh.  Turns out not even transformation passes link in how to read IR.
I sincerely believe the buildbots will finally agree with my system
after this though.  (I don't really understand why all of this has been
working on my system, but not on all the buildbots.)

Create a new tool called llvm-uselistorder to use for verifying use-list
order.  For now, just dump everything from the (now defunct)
-verify-use-list-order pass into the tool.

This might be a better way to test use-list order anyway.

Lang Hames f7acddde5b [MCJIT] Refactor and add stub inspection to the RuntimeDyldChecker framework.
This patch introduces a 'stub_addr' builtin that can be used to find the address
of the stub for a given (<file>, <section>, <symbol>) tuple. This address can be
used both to verify the contents of stubs (by loading from the returned address)
and to verify references to stubs (by comparing against the returned address).

Example (1) - Verifying stub contents:

Load 8 bytes (assuming a 64-bit target) from the stub for 'x' in the __text
section of f.o, and compare that value against the addres of 'x'.

# rtdyld-check: *{8}(stub_addr(f.o, __text, x) = x

Example (2) - Verifying references to stubs:

Decode the immediate of the instruction at label 'l', and verify that it's
equal to the offset from the next instruction's PC to the stub for 'y' in the
__text section of f.o (i.e. it's the correct PC-rel difference).

# rtdyld-check: decode_operand(l, 4) = stub_addr(f.o, __text, y) - next_pc(l)
l:
        movq    y@GOTPCREL(%rip), %rax

Since stub inspection requires cooperation with RuntimeDyldImpl this patch
pimpl-ifies RuntimeDyldChecker. Its implementation is moved in to a new class,
RuntimeDyldCheckerImpl, that has access to the definition of RuntimeDyldImpl.

David Blaikie 4b9ae52ac1 Correct the ownership passing semantics of object::createBinary and make them explicit in the type system.
createBinary documented that it destroyed the parameter in error cases,
though by observation it does not. By passing the unique_ptr by value
rather than lvalue reference, callers are now explicit about passing
ownership and the function implements the documented contract. Remove
the explicit documentation, since now the behavior cannot be anything
other than what was documented, so it's redundant.

Also drops a unique_ptr::release in llvm-nm that was always run on a
null unique_ptr anyway.

Justin Bogner 759645ea89 Support: Fix option handling when using cl::Required with aliasopt
Until now, attempting to create an alias of a required option would
complain if the user supplied the alias, because the required option
didn't have a value. Similarly, if you said the alias was required,
then using the base option would complain that the alias wasn't
supplied. Lastly, if you put required on both, *neither* option would
work.

By changning alias to overload addOccurrence and setting cl::Required
on the original option, we can get this to behave in a more useful
way. I've also added a test and updated a user that was getting this
wrong.

There is one FIXME in the code and I’m all ears to anyone that can help me

anywhere on the command line.  Such that "llvm-nm -s __TEXT __text foo.o"

Tim Northover 07f99fb769 llvm-readobj: fix MachO relocatoin printing a bit.
There were two issues here:
1. At the very least, scattered relocations cannot use the same code to
   determine the corresponding symbol being referred to. For some reason we
   pretend there is no symbol, even when one actually exists in the symtab, so to
   match this behaviour getRelocationSymbol should simply return symbols_end for
   scattered relocations.
2. Printing "-" when we can't get a symbol (including the scattered case, but
   not exclusively), isn't that helpful. In both cases there *is* interesting
   information in that field, so we should print it. As hex will do.

Lang Hames e1c1138a38 [RuntimeDyld] Add a framework for testing relocation logic in RuntimeDyld.
This patch adds a "-verify" mode to the llvm-rtdyld utility. In verify mode,
llvm-rtdyld will test supplied expressions against the linked program images
that it creates in memory. This scheme can be used to verify the correctness
of the relocation logic applied by RuntimeDyld.

The expressions to test will be read out of files passed via the -check option
(there may be more than one of these). Expressions to check are extracted from
lines of the form:
# rtdyld-check: <expression>

This system is designed to fit the llvm-lit regression test workflow. It is
format and target agnostic, and supports verification of images linked for
remote targets. The expression language is defined in
llvm/include/llvm/RuntimeDyldChecker.h . Examples can be found in
test/ExecutionEngine/RuntimeDyld.

Alp Toker 614717388c Introduce a string_ostream string builder facilty
string_ostream is a safe and efficient string builder that combines opaque
stack storage with a built-in ostream interface.

small_string_ostream<bytes> additionally permits an explicit stack storage size
other than the default 128 bytes to be provided. Beyond that, storage is
transferred to the heap.

This convenient class can be used in most places an
std::string+raw_string_ostream pair or SmallString<>+raw_svector_ostream pair
would previously have been used, in order to guarantee consistent access
without byte truncation.

The patch also converts much of LLVM to use the new facility. These changes
include several probable bug fixes for truncated output, a programming error
that's no longer possible with the new interface.

Overall this looks like a more efficient and less brittle api.

Also clean up the Mach-O printing of archive membernames in llvm-nm to use

Rafael Espindola 6b244b1348 Use lib/LTO directly in the gold plugin.
The tools/lto API is not the best choice for implementing a gold plugin. Among
other issues:

* It is an stable ABI. Old errors stay and we have to be really careful
  before adding new features.
* It has to support two fairly different linkers: gold and ld64.
* We end up with a plugin that depends on a shared lib, something quiet
  unusual in LLVM land.
* It hides LLVM. For some features in the gold plugin it would be really
  nice to be able to just get a Module or a GlobalValue.

This change is intended to be a very direct translation from the C API. It
will just enable other fixes and cleanups.

Tested with a LTO bootstrap on linux.

Kevin Enderby 246a460d1f Add "-format darwin" to llvm-size to be like darwin's size(1) -m output, and
and the -l option for the long format.  Also when the object is a Mach-O
file and the format is berkeley produce output like darwin’s default size(1)
summary berkeley derived output.

Like System V format, there are also some small changes in how and where
the file names and archive member names are printed for darwin and
Mach-O.

Like the changes to llvm-nm these are the first steps in seeing if it is
possible to make llvm-size produce the same output as darwin's size(1).

Rafael Espindola 2a826e40fa Finishing touch for the std::error_code transition.
While std::error_code itself seems to work OK in all platforms, there
are few annoying differences with regards to the std::errc enumeration.

This patch adds a simple llvm enumeration, which will hopefully avoid build
breakages in other platforms and surprises as we get more uses of
std::error_code.

Tobias Grosser 9190e0dd62 opt: Initialize asm printers
Without initializing the assembly printers a shared library build of opt is
linked with these libraries whereas for a static build these libraries are dead
code eliminated. This is unfortunate for plugins in case they want to use them,
as they neither can rely on opt to provide this functionality nor can they link
the printers in themselves as this breaks with a shared object build of opt.

This patch calls InitializeAllAsmPrinters() from opt, which increases the static
binary size from 50MB -> 52MB on my system (all backends compiled) and causes no
measurable increase in the time needed to run 'make check'.
