macros SETUP_FRAME_ADDRESSES and RETURN_ADDR_IN_PREVIOUS_FRAME.

RETURN_ADDR_IN_PREVIOUS_FRAME, RETURN_ADDR_RTX): Define.

From-SVN: r3608

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

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.

But maybe turn it off again.

(expr -> statement expression): Push and pop iterator stack.
(stmt -> expr): Use iterator_expand.
(all_iter_stmt): New rule.

From-SVN: r3580

(finish_decl): For iterator, require initial value, make a save_expr.

From-SVN: r3579

(C_OBJS, OBJC_OBJS): Add c-iterate.o.

(gcc.o): Delete dep obstack.h.

(subst, case NOT): If STORE_FLAG_VALUE==-1, treat an ASHIFTRT of just the sign bit as if it were an LT.

(subst, case NOT): If STORE_FLAG_VALUE==-1, treat an ASHIFTRT of just the
sign bit as if it were an LT.
(subst, case XOR): Likewise for STORE_FLAG_VALUE==1 and an LSHIFTRT.
(simplify_and_const_int, case LSHIFTRT): If shifting a sign bit copy,
start shift at the sign bit.
(simplify_shift_const): Likewise for ASHIFTRT.

(BYTE_LOADS_EXTEND): Fix typo when defining.
(setup_incoming_promotions): Set modes properly.

From-SVN: r3575

(subst_constants): Use proper mode when getting equivalent constant for paradoxical SUBREG in SET_DEST.

(subst_constants): Use proper mode when getting equivalent constant for
paradoxical SUBREG in SET_DEST.
(mark_stores): Clean up and tighten to properly handle hard regs.

	* pa.md (split for symbol_ref+int): New define_split for hte
	combiner.

From-SVN: r3572

        * pa.c (symbolic_expression_p): New function.
        (hppa_legitimize_address): Old LEGITIMIZE_ADDRESS moved
        here.  Handle symbol_ref + displacement addresses.
        Use rounding instead of masking off lower bits.
        Avoid creating useless pseudos and strip off CONST in
        (const (...)) expressions to make processing easier.

From-SVN: r3571

	* pa.h (CONSTANT_ADDRESS_P): Do not accept symbolic
	addresses.
	(LEGITIMIZE_ADDRESS): Just a stub now.  Call
	hppa_legitimize_address to do the real work.
