Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead.  This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress.  (GlobalDCE can also handle the given tescase, but we only run that at -O3.)  Found while looking at PR11180.

bring the debugger to the desired state.

This patch makes BenchBase inherit from TestBase, instead of Base (which is a parent class of
TestBase).  This is so that we can also enjoy the Pythonic way of bringing the lldb debugger
to a desired state before running the benchmark and collect statistics.

std::string and modified all places that used the std::string it returned
to use the "const char *".

Also modified the expression parser to not crash when a function type fails
to copy into the expression AST context.

Define __STDC__ in -fms-extensions mode; defining it is consistent with gcc, and not defining it causes the system headers on multiple platforms to break with -fms-extensions because they assume the lack of a definition of __STDC__ implies a traditional (pre-ANSI) preprocessor.

instead of a semicolon (as sometimes happens during refactorings). When such a
comma is seen at the end of a line, and is followed by something which can't
possibly be a declarator (or even something which might be a plausible typo for
a declarator), suggest that a semicolon was intended.

When checking the availability of instructions using the TLI, a 'promoted'
instruction IS available. It means that the value is bitcasted to another type
for which there is an operation. The correct check for the availablity of an
instruction is to check if it should be expanded.

process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

    child=None, child_prompt=None, use_cmd_api=False

By default, expect a pexpect spawned child and child prompt to be
supplied (use_cmd_api=False).  If use_cmd_api is true, ignore the child
and child prompt and use self.runCmd() to run the hooks one by one.

Modify existing client to reflect the change.

Patch by Dimitry Andric.

llvm-svn: 142531

Use literal pool loads instead of MOVW/MOVT for materializing global addresses when optimizing for size.

On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is
codesize including literal pools.

The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there
is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries.

Fixes PR11087.

This tests TableGen's paste functionality.

llvm-svn: 142526

Add a paste operator '#' to take two identifier-like strings and joint
them.  Internally paste gets represented as a !strconcat() with any
necessary casts to string added.

This will be used to implement basic for loop functionality as in:

for i = [0, 1, 2, 3, 4, 5, 6, 7] {
  def R#i : Register<...>
}
