(FP_mode_reg): Trimmed to a smaller size, less overhead.
(FP_MODE_REG): New macro over which FP_mode_reg will be accessed.
(mark_regs_pat, straighten_stack): New functions.
(reg_to_stack): Amend initialisation of FP_mode_reg.
Mark FP registers mentioned in USE insns before NOTE_INSN_FUNCTION_BEG.
(get_true_reg): Eliminate FP subreg accesses in favour of the actual FP
register in use.
(record_reg_life_pat): Make it work on SUBREGs as well.  Make use of the new
mark_regs_pat function.  Handle USE insns if called unnested.
(record_reg_life): Don't check for QImode again, we know that it is there.
Process CALL_INSNs like all other insns, they might `use' some FP argument
registers if register passing.
(stack_result_p): Changed in stack_result and returning an rtx.
(stack_reg_life_analysis): Take a new stackentry state argument.
Use stack_result and the rtx to mark using mark_regs_pat.  This ensures that
types that need multiple FP registers are handled correctly
Delete the no_live_regs shortcut to save space.
Use stackentry state to determine filled registers.
(replace_reg): Accept COMPLEX_FLOAT as well.
(move_for_stack_reg): Optimise away some pointer dereferencing.
(subst_stack_regs): Make sure the stack is in the right order and of the right
size for register passing.
(goto_block_pat): Make sure the stack is in the right order to return possible
multi-register values from the function.
(convert_regs): Fix comment about CALL_INSN, it's no longer valid.
Make sure the stack is of the right size and in the right order to return
possible multi-register values from the function.

(valid_machine_attribute): Use new function attribute_in_list, makes
sure type_attribute_variants are reused even when attributes have
parameters.
Assign any new type to TREE_TYPE (decl).
(attribute_in_list): New function.
(attribute_list_contained): Use it.

Declare strerror if HAVE_STRERROR is defined; otherwise declare
sys_errlist and sys_nerr.

(fold, shift and rotate): Don't call tree_int_cst_sgn on non-integer.
(fold, case LROTATE_EXPR): If constant count, convert to RROTATE_EXPR.
(fold, case RROTATE_EXPR): Sometimes commute logical op with rotate.
Delete pair of counteracting shifts.

TARGET_FASTCODE, TARGET_CLEN3, TARGET_CLEN0, TARGET_OPTIONS): Delete.
(TARGET_SWITCHES): Delete -mclen3 and -mclen0 options.
(TARGET_DEFAULT): Is zero.
(OVERRIDE_OPTIONS): Delete code to set max_count_si and max_count_hi.
(SPECIAL_REG): New macro.
(HARD_REGNO_MODE_OK): Allow any mode in any general register.
(GO_IF_LEGITIMATE_ADDRESS): Delete constant + reg address case.
(MOVE_RATIO): Define to 2 when TARGET_SMALLCODE.
(max_si, max_hi, max_count_si, max_count_hi): Delete.

(rotlsi3_1): Set T reg instead of clobbering it.
(ashrsi3): Use expand_ashiftrt instead of gen_shifty_op.
(movsi_i, movhi_i, movsf_i): Add conditions to reject patterns
needing a reload.
(movdi-2, movdf_k): Correct conditions to reject patterns needing
a reload.
([inverse_]branch_{true,false}): Pass operands to output_branch.
(jump): Delete unnecessary braces.
(call, call_value): Don't use expand_acall.  Force operand0 into
a register.
