  other cases we use the alloc size now.

Zachary Turner 5b1ffdf674 Finish PyCallable -> PythonCallable conversion.
This finishes the effort to port python-wrapper.swig code over to
using PythonDataObjects.

Also included in this patch is the removal of `PyCallable` from
`python-wrapper.swig`, as it is no longer used after having been
replaced by `PythonCallable` everywhere.

There might be additional cleanup as followup patches, but it should
be all fairly simple and minor.

James Y Knight 7aefb5b623 Correct atomic libcall support for __atomic_*_fetch builtins.
In r244063, I had caused these builtins to call the same-named library
functions, __atomic_*_fetch_SIZE. However, this was incorrect: while
those functions are in fact supported by GCC's libatomic, they're not
documented by the spec (and gcc doesn't ever call them).

Instead, you're /supposed/ to call the __atomic_fetch_* builtins and
then redo the operation inline to return the final value.

Nathan Slingerland f0e107e38a [llvm-profdata] Add check for text profile formats and improve error reporting
Summary:
This change addresses two possible instances of user error / confusion when
merging sampled profile data.

Previously any input that didn't match the raw or processed instrumented format
would automatically be interpreted as instrumented profile text format data.
No error would be reported during the merge.

Example:
If foo-sampled.profdata and bar-sampled.profdata are binary sampled profiles:

Old behavior:
$ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -output foobar-sampled.profdata
$ llvm-profdata show -sample foobar-sampled.profdata
error: foobar-sampled.profdata:1: Expected 'mangled_name:NUM:NUM', found  lprofi

This change adds basic checks for valid input data when assuming text input.
It also makes error messages related to file format validity more specific about
the assumbed profile data type.

New behavior:
$ llvm-profdata merge foo-sampled.profdata bar-sampled.profdata -o foobar-sampled.profdata
error: foo.profdata: Unrecognized instrumentation profile encoding format
Perhaps you forgot to use the -sample option?

Dan Gohman cf4748f180 [WebAssembly] Reapply r252858, with svn add for the new file.
Switch to MC for instruction printing.

This encompasses several changes which are all interconnected:
 - Use the MC framework for printing almost all instructions.
 - AsmStrings are now live.
 - This introduces an indirection between LLVM vregs and WebAssembly registers,
   and a new pass, WebAssemblyRegNumbering, for computing a basic the mapping.
   This addresses some basic issues with argument registers and unused registers.
 - The way ARGUMENT instructions are handled no longer generates redundant
   get_local+set_local for every argument.

This also changes the assembly syntax somewhat; most notably, MC's printing
does not use sigils on label names, so those are no longer present, and
push/pop now have a sigil to keep them unambiguous.

The usage of set_local/get_local/$push/$pop will continue to evolve
significantly. This patch is just one step of a larger change.

Zachary Turner b58fb2f47a Begin converting uses of PyCallable to PythonCallable.
PyCallable is a class that exists solely within the swig wrapper
code.  PythonCallable is a more generic implementation of the same
idea that can be used by any Python-related interop code, and lives
in PythonDataObjects.h

The CL is mostly mechanical, and it doesn't cover every possible
user of PyCallable, because I want to minimize the impact of this
change (as well as making it easier to figure out what went wrong
in case this causes a failure).  I plan to finish up the rest of
the changes in a subsequent patch, culminating in the removal of
PyCallable entirely.

Ramkumar Ramachandra 314b752513 Use uniqueness of C++ fully-qualified names to resolve conflicts
A very expected layout: source tree is in ~/src/llvm, the build directory is in
~/src/llvm-build, and the install location is in /usr/local/{lib,include}.

The DWARF information in /usr/local/lib/libLLVM.a for ilist.h points to
~/src/llvm-build/include/llvm/ADT/ilist.h. Now, when someone includes
"llvm/ADT/ilist.h" and links against /usr/local/lib/libLLVM.a. Disaster.

The DWARF information in libUser.so for ilist.h points to two locations: the one
in /usr/include, and the one in ~/src/llvm-build/include. LLDB gets confused.

Let's uniquify fully-qualified names and never trip on such a thing.

Kuba Brecka 3ecce92a52 [tsan] Allow symbolizers that don't obtain global symbol sizes
The default symbolizer, `llvm-symbolizer` provides sizes for global symbols. On OS X, we want to also allow using `atos` (because it's available everywhere and users don't need to copy/install it) and `dladdr` (it's the only available option when running in a sandbox). However, these symbolizers do not supply the symbol sizes, only names and starting addresses. This patch changes the reporting functions to hide the size of the symbol when this value is unavailable, and modifies tests to make this part of the report "optional".
