Initializing explicitely is necessary for frontends using mode_P that do
not call be_get_backend_param() early.

Just guessing a 32bit mode is not too helpful.  Leave the mode_P
initialization to the backend or frontend.

Your only choice is irma_twos_complement anyway now.

Moving the bits and pieces to generate Nodes.html is better kept with
the homepage repository which already has stylesheets and tools to
generate nice looking html. gen_ir.py will be invoked on the ir_spec.py
file from there.

The homepage uses those functions to generate firm graph
examples/snippets without dumping a whole function.

This is necessary to make the homepage generator not call private
libfirm interface any longer.

Method types have no mode anymore.

lower: Factor out common code for handling parameter, result and entity types in softfloat lowering.

Checking 'is_Primitive_type()' achieves the same as 'mode && mode_is_float(mode)'.

get_lowered_mode() checks for mode_is_float().

This fixes opt/fehler323.c and ack/test2.c on amd64.
ia32 was not broken and just adjusted for consistency.

Methods are not pointers, so using mode_P and its size do not make sense.

All backends just copy these Projs.

This happened when Shrs(Shl(Load, c), c) got transformed to a movsx loading from memory and the Shl had further users.

This fixes backend/duplicate_proj2.c.

Moving Pin nodes down through Phi nodes changes the semantics of the
graph and may prevent further optimizations like PRE.

This fixes opt/fehler322.c.

be: Simply use '&${ARCH}_class_reg_req_${CLASS}' instead of '${ARCH}_reg_classes[CLASS_${ARCH}_${CLASS}].class_req'.

According to Gaisler's GRIP documentation, section 77.2.7, the LEON
requires the ASI 0x0A for CAS usage in user mode.
