Just state the copyright and the project the files belong to. You can
then find the COPYING file for the whole project.

In particular this ensures that the backend has segments for the PIC symbols and trampolines.

bemain: Centrally call be_gas_end_compilation_unit() and be_emit_exit() instead of doing it per backend.

Also remove the now write-only attribute main_env from struct arch_env_t.

bemain: Centrally call be_emit_init() and be_gas_begin_compilation_unit() instead of doing it per backend.

It only measures initializing a single struct.

Remove empty init_graph functions from arm and sparc backends.

There was only one user of this information left, which is changed to directly use irgs.

irverify already checks the dominance property

Added some additional functions that allow direct access to some fields
of the backend params struct.  These functions avoid struct type,
thereby making interfacing with the jFirm library easier.

Return the profile init irg from ir_profile_instrument() instead of guessing that it is the last irg.

This makes it consistent with other firm analyse functions. Also removes
the unnecessary return value.

Also factor out code that emits the label and comment at the beginning
of a basic block.

This is used to implement C99 "inline"/GNU89 "extern inline" ie. an
entity which is externally defined but where we know an inlineable
definition anyway.

Remove the stabs debugoutput code and with it all the complexity of a
modular debug output system. The only remaining debug output module is
dwarf.

Add a phase before coloring thats split all live variables before each instruction that defines a paired value.

This also plugs liveness related memory leaks

The opcode list was a member of irprog before which wasn't really
handled consistently. Also make sure opcodes are properly freed at
ir_finish().

It should only be used by construction algorithms

Make sure all types are in the global type list, remove type_walk_prog
which was a strange alternative to type_walk attempting to not miss
types not in the global list.

This should fix problems with uninitialized backends when
be_get_backend_param() wasn't called also calls be_lower_for_target if
the user hasn't done so yet.

get_backend_irg_list - none of our backends uses it and in the future
                       the backend should drive the compilation and not
                       give hints to a generic driver
reg_class_alignment  - unused

This also means that dependent modules like bedbgout should be
initialized by begnuas.
