(sh_handle_renesas_attribute): New.
(sh_attr_renesas_p, sh_cfun_attr_renesas_p): New.
(sh_ms_bitfield_layout_p): Support renesas attribute also.
(sh_output_mi_thunk): Pass function to aggregate_value_p. *
config/sh/sh.h (TARGET_SWITCHES): Add -mrenesas as an alias for
-mhitachi.
(STRUCT_VALUE_REGNUM, STRUCT_VALUE, RETURN_IN_MEMORY): Moved to
target hooks.
(sh_args): Add renesas_abi flag.
(INIT_CUMULATIVE_ARGS): Set it. Pass fndecl to aggregate_value_p.
(FUNCTION_ARG_ADVANCE, FUNCTION_ARG): Move to sh.c.
(PASS_IN_REG_P): Support renesas attribute. Pass DF and TF on the
stack for the renesas abi.
(STRICT_ARGUMENT_NAMING, PRETEND_OUTGOING_VARARGS_NAMED,
SETUP_INCOMING_VARARGS, EXPAND_BUILTIN_SAVEREGS,
PROMOTE_PROTOTYPES): Moved to sh.c. * config/sh/sh.md (call): Set
call cookie to indicate renesas calls.
* decl.c (finish_function): Pass fndecl to aggregate_value_p.
* misc.c (default_pass_by_ref): Convert to calls.return_in_memory
hook.
From-SVN: r71048
* builtins.c (expand_builtin_setjmp): Use emit_jump to jump around
the != 0 case, which ensures pending stack adjustments are flushed.
From-SVN: r70958
* builtins.c (expand_builtin_expect_jump): Save pending_stack_adjust
and restore it if returning NULL.
* gcc.dg/20030826-2.c: New test.
From-SVN: r70844
* builtins.c (fold_builtin_bitop): New function to perform constant
folding of ffs, clz, ctz, popcount and parity builtin functions
and their long and long long variants (such as ffsl and ffsll).
(fold_builtin): fold_builtin_bitop when appropriate.
* simplify-rtx.c (simplify_unary_operation): Honor both
CLZ_DEFINED_VALUE_AT_ZERO and CTZ_DEFINED_VALUE_AT_ZERO when
evaluating clz and ctz at compile-time, for operands wider
than HOST_WIDE_INT.
From-SVN: r70806
* builtins.c (expand_builtin_mathfn): Rearrange so that we only
return 0 for invalid argument types. Instead drop through to a
call of expand_call at the bottom of function. If op is SQRT,
try attaching a SQRT rtx as the REQ_EQUAL note of the libcall.
