Richard Henderson 106c3c10bf Force the use of stack_pointer_offset in computing the frame size.
By exporting padding[012] and to_allocate from ix86_compute_frame_layout,
we encouraged re-computation of the size of the local frame.  All of the
truly relevant offsets are now exported directly, and should be compared
against directly.

Richard Henderson 87ec2632b8 Remove code duplication in ix86_expand_epilogue.
Union the undo of the frame pointer between the pop and move
code paths.

Combine the local frame stack deallocation with the one for
ix86_static_chain_on_stack, if possible.

Richard Henderson c9f4c45115 Describe unwinding for realigned frames explicitly.
We had been relying on some extremely fragile code within
dwarf2out in order to guess what to do with aligned stack
frames, which broke when we decided to perform the stores
to the aligned stack frame via EBP instead of ESP.

Instead, emit the appropriate unwinding instructions from
the backend.  This requires adding a new reg-note in order
to describe a register save at an arbitrary address.

Richard Henderson ec7ded37e7 Emit the prologue/epilogue using frame offsets.
Record register save offsets in ix86_frame.

Move SP/FP offsets into the global state; update them everywhere
we currently handle CFA offsets.

Use that global state to choose base registers and offsets for
the register saves and restores.

There is a bug fix contained herein, whereby r11 could be clobbered
along an indirect sibcall path when the stack frame is very large (>2GB).
The emit_restore_{sse_,}regs_using_mov functions didn't handle this
case, but pro_epilogue_adjust_stack does.

Richard Henderson 17959958bc Remove duplicate definition of TARGET_64BIT_MS_ABI.
The definition in cygming.h differed from the definition in i386.h in
that the predicate was true for 32-bit when outside of any function.
Which (a) seems wrong and (b) never matters because the predicate is
only tested in terms of REGPARM and RED_ZONE, both of which are tied
to functions.

Richard Henderson 9bf40564e1 Eliminate most of the conditional compilation from dwarf2out.c.
Trying to reduce the amount of code compiled when dwarf2 debug
info and/or dwarf2 unwind info are disabled results in a twisted
mess.  Don't bother -- just build it all even if it's not going
to be used.
