(lrotate_double): Use LOWPART, HIGHPART, and BASE.
(rrotate_double): Likewise.
(div_and_round_double): Major changes to code for general case.
Now it actually produces non-garbage results for large operands.

divisor < BASE.

When determining if needs are nongroup needs, ignore inactive or optional
reloads.
(reload_reg_used_in_op_addr_reload): New variable to indicate when reloads of
class RELOAD_FOR_OPADDR_ADDR are in use.
(mark_reload_reg_in_use, clear_reload_reg_in_use): Process reloads of class
RELOAD_FOR_OPADDR_ADDR.
(reload_reg_free_p, reload_reg_free_before_p, reloads_conflict): Likewise.

* pa-osf.h (SIZE_TYPE): Define as "long unsigned int" to be
compatable with system include files.
* pa1-osf.h (SIZE_TYPE): Likewise.
* pa1-osf.h (WCHAR_TYPE): Define as "short unsigned int".
(WCHAR_TYPE_SIZE): Define as 16 bits.

big-endian mode.
(fp_immediate_constant): Fix typo in argument declaration.
From-SVN: r7449
(storeinthi): Rework to generate better code, add big-endian support.
(movhi): Add support for processors running in big-endian mode.
(movhi_bigend): New expansion pattern.
(matcher for movhi): Remove incorrect alternative for storing HImode to
memory. Only match when little endian.
(matcher for big-endian movhi): New pattern.
(matchers/peepholes for extended pre/post increment HImode loads): Only
match when little-endian.
(matcher for operating on adjacent memory locations): Load operation into
arith operands.

(FUNCTION_PROFILER, TRAMPOLINE_TEMPLATE, ASM_FILE_START,
ASM_OUTPUT_REG_{PUSH,POP}, PRINT_OPERAND_ADDRESS): Output register
prefix before any explicit register name.
(ASM_OUTPUT_LONG_DOUBLE, ASM_OUTPUT_DOUBLE, ASM_OUTPUT_FLOAT,
ASM_OUTPUT_COMMON): Output the target dependent comment char.
(ASM_FILE_START): Output register alias for r10.
(REGISTER_NAMES): Output "r9" now for r9, not "rfp".
(ADDITIONAL_REGISTER_NAMES): New macro.
From-SVN: r7444
(REGNO_OK_FOR_FP_P): Use FP_REGNO_P.
(FUNCTION_VALUE_REGNO_P): Revert last change.
(CONDITIONAL_REGISTER_USAGE): Partially revert last changes;
Make non-existing 1.0 fp regs fixed, including odd-numbered regs.
(enum reg_class): Get rid of SNAKE_FP_REGS, GENERAL_OR_SNAKE_FP_REGS,
and NON_SHIFT_REGS.
(REG_CLASS_NAMES): Likewise.
(REG_CLASS_CONTENTS): Likewise.
(REGNO_REG_CLASS): Likewise.
(HARD_REGNO_MODE_OK): Corresponding changes. Don't force 1.0 fpregs
to even regno here; fixed_regs does the job better.
(FP_REG_CLASS_P): Get rid of SNAKE_FP_REGS.
(REG_CLASS_FROM_LETTER, case 'z'): Deleted.
(HARD_REGNO_NREGS): Partially revert last change.
(CLASS_MAX_NREGS): Partially revert last change.
From-SVN: r7438
(all patterns): Update instruction generation to reflect new meanings of
constraints 'K' and 'L'. Use output type 'B' to generate an inverted
constant. Use output type 'N' to generate a negated floating point
constant.
From-SVN: r7436
* pa.h (TARGET_SWITCHES): Enable TARGET_LONG_CALLS when
TARGET_PORTABLE_RUNTIME is enabled.
* pa.c (output_call): If TARGET_LONG_CALLS is enabled, then emit
an inline long-call sequence.
* pa.md (millicode define_delay): Disable delay slots if
TARGET_LONG_CALLS.
(call_internal_reg, call_value_internal_reg): If TARGET_LONG_CALLS
is enabled, then emit an inline long-call sequence. Fix length
