This patch makes selectors in the Objective-C language be pointers
to a struct { void *sel_id, char *sel_types }, where the sel_types
element is the type encoding of the method arguments.
From-SVN: r7622
* objc-act.c (get_proto_encoding, build_typed_selector_reference):
New fucnctions. (UTAG_PROTOCOL): New define.
(objc_selector_template, flag_typed_selectors): New variables.
(objc_init): set flag_typed_selectors if -fgnu-runtime.
(synth_module_prologue): Change declaration of
_OBJC_SELECTOR_TABLE when flag_typed_selectors is non-null.
(build_module_descriptor): Make sure the generated constructor
function is declared public.
(build_selector): Only cast to SEL when not doing typed selectors.
(build_selector_translation_table): Rewrite initialization.
(build_tmp_function_decl): Make up new name when called, since it
may now be called multiple times.
(hack_method_prototype): Use init_function_start to reinit args
machinery. Also set current_function_decl before calling
assign_parms.
(generate_protocols): Don't generate encoding twice.
(build_selector_template): New function.
(build_method_list_template): Generate (void*)0 as first element,
not (int)0.
(build_message_expr): move the call to build_selector_reference
towards the end, where we have determined the function prototype.
From-SVN: r7620
(HARD_FRAME_POINTER_REGNUM): New macro.
(CONDITIONAL_REGISTER_USAGE, REG_CLASS_CONTENTS, REGNO_REG_CLASS):
Show register 63 is not an FP register.
(REGHNO_OK_FOR_BASE_P, REG_OK_FOR_BASE_P, REGISTER_NAMES): Likewise.
(ALPHA_ROUND): New macro.
(STARTING_FRAME_OFFSET, ELIMINABLE_REGS, INITIAL_ELIMINATION_OFFSET):
Modify to reflect save area between outgoing args and local vars.
From-SVN: r7607
Spill HARD_FRAME_POINTER_REGNUM if not FRAME_POINTER_REGNUM and frame pointer
is needed.
(spill_hard_reg): If CANT_ELIMINATE, set regs_ever_live; no longer done by
callers.
From-SVN: r7605
(global_alloc): Make a more accurate attempt to see if the frame pointer will
be used.
If it is, show HARD_FRAME_POINTER_REGNUM used if its not the same as
FRAME_POINTER_REGNUM.
From-SVN: r7604
(ceil_log2): New function.
(choose_multiplier): New function.
(invert_mod2n): New function.
(expand_mult_highpart_adjust): New function.
(expand_mult_highpart): New function.
(EXACT_POWER_OF_2_OR_ZERO_P): New macro.
(expand_divmod): Almost completely rewritten.
(expand_shift): Don't truncate immediate shift count, it doesn't work
for types smaller than int.
From-SVN: r7598
(cpu_type, sparc_cpu_type): Rename to arch_type and
sparc_arch_type.
(CPP_SPEC): Handle -msupersparc.
(MASK_SUPERSPARC, TARGET_SUPERSPARC): New macros.
(TARGET_SWITCHES): Add -msupersparc and -mcypress.
(ADJUST_COST): New macro.
From-SVN: r7587
(cpu attribute): Rename to arch attribute. Add a new
cpu attribute. Fix all users.
(type attribute): Add ialu, shift, imul, fpdivs, and fpdivd.
Delete fpdiv.
(function units): Add Cypress and Supersparc versions of each.
(addsi3, subsi3, andsi3, iorsi3, xorsi3): Add ialu type attribute.
(mulsi3): Add imul type attribute.
(divtf3, divdf3): Use fpdivd not fpdiv type attribute.
(divsf3); Use fpdivs not fpdiv type attribute.
(ashlsi3, ashrsi3, lshrsi3): Add shift type attribute.
