Frederic Riss 3137ae9e7f [dsymutil] Use option categories.
Prevent all the unrelated LLVM options to appear in the -help output
by introducing a tool specific option category. As a drive-by improve

Frederic Riss 11ab2b8858 [dsymutil] Rename -v option to -verbose
The dsymutil-classic -v option dumps the tool version rather than
putting it in verbose mode. Rename -v to -verbose and update the
tests that use it (in the process removing it from a few tests that
didn't require it anymore since the -dump-debug-map option was
introduced).
A followup commit will reintroduce the -v option that dumps the
version.

JF Bastien ba70e9e1e6 Fix `llvm-config` to emit the linker flag for the combined shared object built by autoconfig/make instead of the individual components.
Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.

This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.

This change only affects `llvm-config` from builds that use autoconfig/make.

Tobias Grosser 56eab3603a bugpoint: make the number of trim iterations a compile-time constant
Around 10 year ago Chris limited this code to a single iteration by just
dropping a break into the loop body. We now make the number of trim iterations
a compile time constant to be able to play with it and see if this can
improve the bugpoint results. We currently use with '3' still a small and
conservative value, but this can be adjusted in the future, if needed.

I tried to look for a trivial test case, but did not succeed yet.

Davide Italiano 4376ddb88e [llvm-dwarfump] Don't rely on global state, part 3.
Some tools used to rely on a global static variable to keep track of the 
return value for main(). I changed llvm-cxxdump to use exit(1)
and Rafael shortly after did the same with llvm-readobj. This is
(yet) another step towards the goal.

Frederic Riss eb85c8fb09 [dsymutil] Implement support for universal mach-o object files.
This patch allows llvm-dsymutil to read universal (aka fat) macho object
files and archives. The patch touches nearly everything in the BinaryHolder,
but it is fairly mechinical: the methods that returned MemoryBufferRefs or
ObjectFiles now return a vector of those, and the high-level access function
takes a triple argument to select the architecture.

There is no support yet for handling fat executables and thus no support for
writing fat object files.

The debug map contains the timestamp of the object files in references.
We do not check these in the general case, but it's really useful if

appended. This allows llvm-dsymutil to find the right one.

Frederic Riss 1c65094d5b [dsymutil] Implement ODR uniquing for C++ code.
This optimization allows the DWARF linker to reuse definition of
types it has emitted in previous CUs rather than reemitting them
in each CU that references them. The size and link time gains are
huge. For example when linking the DWARF for a debug build of
clang, this generates a ~150M dwarf file instead of a ~700M one
(the numbers date back a bit and must not be totally accurate
these days).

As with all the other parts of the llvm-dsymutil codebase, the
goal is to keep bit-for-bit compatibility with dsymutil-classic.
The code is littered with a lot of FIXMEs that should be
addressed once we can get rid of the compatibilty goal.

One part of my refactoring from r242705 is untenable due to how CMake caches variables. There is no way other than caching to allow variables to be set in one directory and globally readable, but we really don't want to cache the temporary value marking that a directory has already been included.

Chris Bieneman 580d8159d5 [CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.
Re-landing r242059 which re-landed r241621... I'm really bad at this.

Summary (r242059):
This change re-lands r241621, with an additional fix that was required to allow tool sources to live outside the llvm checkout. It also no longer renames LLVM_EXTERNAL_*_SOURCE_DIR. This change was reverted in r241663, because it renamed several variables of the format LLVM_EXTERNAL_*_* to LLVM_TOOL_*_*.

Summary (r241621):
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:

* factored out canonicalizing tool names from paths to CMake variables * removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

Rafael Espindola 2535ea0b83 Create BSD archives by default on OS X.
They should probably be created on anything that is not windows or linux, but I will
test on freebsd before changing that.

With this it is possible to bootstrap with llvm-ar instead of ar+ranlib on OS X.

David Majnemer 3f49e662c8 [CodeView] Add support for emitting column information
Column information is present in CodeView when the line table subsection
has bit 0 set to 1 in it's flags field.  The column information is
represented as a pair of 16-bit quantities: a starting and ending
column.  This information is present at the end of the chunk, after all
the line-PC pairs.

Rafael Espindola a2ed0b0bab Start adding support for writing archives in BSD format.
No support for the symbol table yet (but will hopefully add it today).
We always use the long filename format so that we can align the member,
which is an advantage of the BSD format.

Simon Atanasyan 22c4c9ee8f [yaml2obj] Align section content using AddressAlign field's value
Use AddressAlign field's value to properly align sections content in the
yaml2obj tool. Before this change the yaml2obj ignored AddressAlign and
always aligned section on 16 bytes boundary.

NAKAMURA Takumi 58843eede5 Revert r241621, "[CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working."
It broke the build that relies on LLVM_EXTERNAL_CLANG_*.

Adrian Prantl 437105a4de llvm-objdump: Replace the -macho -raw option with a generic -raw-clang-ast
option that works with all object container formats.
Now that clang modules/PCH are object containers this option is useful to
to construct pipes like

  llvm-objdump -raw-clang-ast foo.pcm | llvm-bcanalyzer -

to inspect the AST contents in a PCH container.
Will be tested via clang.

Belatedly addresses review feedback for r233390.

Chris Bieneman 3765588f65 [CMake] Cleanup tools/CMakeLists.txt to take advantage of the auto-registration that was already partially working.
Summary:
The tools CMakeLists file already had implicit tool registration, but there were a few things off about it that needed to be altered to make it work. This change addresses all that. The changes in this patch are:

* factored out canonicalizing tool names from paths to CMake variables
* removed the LLVM_IMPLICIT_PROJECT_IGNORE mechanism in favor of LLVM_EXTERNAL_${nameUPPER}_BUILD which I renamed to LLVM_TOOL_${nameUPPER}_BUILD because it applies to internal and external tools
* removed ignore_llvm_tool_subdirectory() in favor of just setting LLVM_TOOL_${nameUPPER}_BUILD to Off
* Added create_llvm_tool_options() to resolve a bug in add_llvm_external_project() - the old LLVM_EXTERNAL_${nameUPPER}_BUILD would not work on a clean CMake directory because the option could be created after it was set in code.
* Removed all but the minimum required calls to add_llvm_external_project from tools/CMakeLists.txt

Rafael Espindola be8b0ea854 Delete UnknownAddress. It is a perfectly valid symbol value.
getSymbolValue now returns a value that in convenient for most callers:
* 0 for undefined
* symbol size for common symbols
* offset/address for symbols the rest

Code that needs something more specific can check getSymbolFlags.

Rafael Espindola 7e7be92c7f Common symbols don't have a value.
At least not in the interface exposed by ObjectFile. This matches what ELF and
COFF implement.

Adjust existing code that was expecting them to have values. No overall
functionality change intended.

Another option would be to change the interface and the ELF and COFF
implementations to say that the value of a common symbol is its size.

Alex Lorenz e2d75239d1 llc: Add a 'run-pass' option.
This commit adds a 'run-pass' option to llc, which instructs the compiler to run
one specific code generation pass only.

Llc already has the 'start-after' and the 'stop-after' options, and this new
option complements the other two by making it easier to write tests that want
to invoke a single pass only.

Rafael Espindola 76d650e8d7 Check that COFF .obj files have sections with zero virtual address spaces.
When talking about the virtual address of sections the coff spec says:
  ... for simplicity, compilers should set this to zero. Otherwise, it is an
  arbitrary value that is subtracted from offsets during relocation.

We don't currently subtract it, so check that it is zero.

If some producer does create such files, we can change getRelocationOffset
instead.

Lang Hames 78937c2ae5 [RuntimeDyld] Skip relocations for external symbols with 64-bit address ~0ULL.
Requested by Eugene Rozenfeld of the LLILC team, this feature allows JIT
clients to skip relocations for selected external symbols by returning ~0ULL
from their symbol resolver. If this value is returned for a given symbol,
RuntimeDyld will skip all relocations for that symbol. The client will be
responsible for applying the skipped relocations manually before the code
is executed.
