Don't try to interpret operands that are RTL as if they were trees.

(reg_scan_mark_refs): Set it here.
Accept INSN, not UID as arg.
(reg_scan): Call reg_scan_mark_refs with INSN, not UID.

'rtx *insn' for const_num_delay_slot argument.

macros SETUP_FRAME_ADDRESSES and RETURN_ADDR_IN_PREVIOUS_FRAME.

From-SVN: r3609

RETURN_ADDR_IN_PREVIOUS_FRAME, RETURN_ADDR_RTX): Define.

From-SVN: r3608

Give names to these patterns so they are easier to use.

to the insn in its delay slot.

rtx_equal_function_value_matters is zero.

pop_obstacks calls around rtl_in_saveable_obstack call.

(output_function_prologue): Use m68k svr4 PIC format to
load the address of _GLOBAL_OFFSET_TABLE_ into PIC_OFFSET_TABLE_REG
in function prologue when doing PIC.

(print_operand_address): Always add "@GOT" suffix for the
global object operand when doing PIC.

From-SVN: r3595

(fix_truncdfsi2, fix_truncdfhi2, fix_truncdfqi2):
Use %# instead of #.

(call, call_value): Set SYMBOL_REF_FLAG for the called
function symbol_ref rtx.  In PIC mode, output `bsr FUNC@PLTPC'
when the operand is symbol_ref.

From-SVN: r3594

(ASM_OUTPUT_CASE_LABEL): Always use `swbeg' syntax to
output switch table (m68k.md depends on this to happen).

(LEGITIMATE_PIC_OPERAND_P): Treat a symbol_ref rtx with
SYMBOL_REF_FLAG set a valid PIC operand.

(OVERRIDE_OPTIONS): Turn off function cse when doing pic.

Make the ints in u unsigned.
(f_define): Use ordinary constants for long double
if it's same width as double.
Make __convert_long_double_i unsigned.
