The reload/spill is always scheduled, because we found it in the schedule.

This corrects handling in bestate (non-ignore).
beabi attaches the fpcw to Start/Return due to being callee-save.
This was accidently done before due to being ignored.

This resolves a latent bug that the x87 noreg register was classified as caller save.
The local index of the given register was compared to the global index of the x87 noreg.

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.

Profiling uses a magic function named mcount.
When profiling libFirm, these two symbols with the same name lead to strange problems.

Remove the union aspect to interpret the flags as one unsigned int.

It's really the same stuff just before and after running ia32_x87
simulator, there is no real need to have 2 different things.

Let a flag and the emitter handle printing the pop variant.

This should fix all cases of 64bit switches

noone was using it anyway

This fixes gcc/pr37285.c.

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

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.

It was a member of ir_prog before but not correctly handled.

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().

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
