Add 'sink' cmdline option. Patch by Mikhail Glushenkov!

llvm-svn: 47377

Unbreak build with gcc 4.3: provide missed includes and silence most annoying warnings.

llvm-svn: 47367

Remove attribution from file headers, per discussion on llvmdev.

llvm-svn: 45418

Pass argc by value, not by reference, since it isn't modified.

llvm-svn: 42788

Move the space in overview output for commands out of each of the
commands and into the common code.

llvm-svn: 42752

Make tail merging the default, except on powerPC. There was no prior art
for a target-dependent default with a command-line override; this way
should be generally usable.

Fix PR1318 by reacting appropriately to a mutating option list.

Fix a bug in my earlier commit which exposed positional options backwards.
This fixes llvm-ar.

rearchitect the registration mechanism used by the command line option stuff.
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called. In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main. Most of that
memory is now allocated by non-commandline related stuff.

remove the dead removeArgument method, rename Options to OptionsMap.

llvm-svn: 35690

Add PrintVersionMessage() that tools can use to print version number
without exiting program.

llvm-svn: 33737

Don't use <sstream> in Streams.h but <iosfwd> instead.

llvm-svn: 32340

Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are
now cerr, cout, and NullStream resp.

llvm-svn: 32298

Removed #include <iostream> and replace with llvm_* streams.

llvm-svn: 31927

avoid a ctor/dtor issue with the ProgramName global.

llvm-svn: 30925

shrink anon-ns and mark stuff static. No functionality changes

llvm-svn: 30922

Fix more static dtor issues

Make the ProgramName variable a std::string so we can eliminate the path
portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages. Instead of:
/path/to/llvm/bin/directory/toolname: error message
we will now get:
toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

If the Program name was NULL then all further output sent to std::cerr was
suppressed.

Add an out-of-line virtual method to provide a home for the cl::option class.
