Now the template backend has a node, which can represent an adress with an offset.

We never used the distinction which flags get modified, so just simplify the specification a bit.

The next release will feature a cmake build.

It was a nice experiment but I do not plan to keep this up to date.

This is meant for the release because users often expect things like an
install target pkg-config scripts or project files for their favorite
IDE.

Main firm development will stay with the simple Makefile, we only plan
to update the cmake build for releases.

This fixes gcc/pr43784_2.c.

Now we can distinguish from reg to mem (AMD64_OP_ADDR_REG) and from mem to reg (AMD64_OP_REG_ADDR) operations.

There is no node left that uses it.

We use lower_CopyB anyway so there are no copybs left when lowering.
They are all lowered to load/store sequences or memcpy calls.

This avoids AnyVal/additional Keep constructins.

I'm not proud of the 4 restriction but for now this works.

There is plain no need to.

arm_cmp_attr_t contains an arm_shifter_operand_t as base, but this was not checked.
This should correct langshootout/bintree.c.

This uses the newly introduced be_Relocation node to perform most PIC
transformations in ia32_pic.c. This introduces the elf and elf-no-plt
PIC modes. The "efl" mode does not work yet because the additional ebx
input makes calls register pressure unfaithful.

This node will be used as a helper for PIC lowering passes which want to
force a specific relocation getting used for an entities address.

One Conv is sufficient.

The modes did not match in several places.

We only need to force a specific frame entity size if we are actually
going to store one for the bitcast. We must not do that when we load from
an existing memory location.

This fixes backend/frame_entity.c

Simplify the creation of instrinsic/runtime function entities a bit and avoid creating duplicate types.
