lib2funcs.S (TRAMPOLINE_SIZE): Change from 49 to 59. * config/xtensa/lib2funcs.S (TRAMPOLINE_SIZE): Change from 49 to 59. * config/xtensa/xtensa-config.h (XCHAL_HAVE_CONST16, XCHAL_HAVE_L32R): New. * config/xtensa/xtensa-protos.h (non_const_move_operand, xtensa_load_constant, xtensa_function_prologue, xtensa_function_epilogue): Delete prototypes. (xtensa_expand_prologue): New. * config/xtensa/xtensa.c (frame_size_const, TARGET_ASM_FUNCTION_PROLOGUE, TARGET_MACHINE_DEPENDENT_REORG, non_const_move_operand, xtensa_load_constant, xtensa_reorg, xtensa_function_prologue): Delete. (add_operand, xtensa_mem_offset): Formatting. (move_operand): If the const16 option is available, allow any SFmode and SImode constants. (xtensa_emit_move_sequence): Inline the former contents of xtensa_load_constant with modifications to handle the const16 option. (override_options): Add xtensa_char_to_class['W'] and set it to the general register class only if the const16 option is enabled. Fix formatting. Disallow PIC when using the const16 option. (print_operand): Reorganize to switch on "letter" instead of the RTL code. Add output_operand_lossage calls for invalid cases. Add support for 't' and 'b' letters. (xtensa_expand_prologue): New function to replace xtensa_function_prologue and xtensa_reorg. (xtensa_function_epilogue): Declare this as static. Delete code to print the retw.n or retw instruction. (xtensa_return_addr): Use A0_REG instead of 0. (xtensa_rtx_costs): Add costs for using the const16 option. * config/xtensa/xtensa.h (MASK_CONST16, TARGET_CONST16): New. (TARGET_DEFAULT): Add CONST16 if L32R instructions not available. (TARGET_SWITCHES): Add "const16" and "no-const16". (REG_CLASS_FROM_LETTER): Add comment about new 'W' letter. (EXTRA_CONSTRAINT): Change 'T' constraint to only apply when not using the const16 option. (TRAMPOLINE_TEMPLATE): Rewrite to avoid hardwired use of l32r insn. (TRAMPOLINE_SIZE): Change from 49 to 59. (INITIALIZE_TRAMPOLINE): Adjust offsets to match new trampoline. (GO_IF_LEGITIMATE_ADDRESS): Do not allow constant pool addresses when using the const16 option. (PREDICATE_CODES): Delete non_const_move_operand. * config/xtensa/xtensa.md (define_constants): Add A1_REG, A8_REG, and UNSPECV_ENTRY. (movdi, movdf): If the source is a constant, always expand to a sequence of movsi insns. (movdi_internal, movdf_internal): Remove alternative using l32r insns. (movsi_internal, movsf_internal): Add alternative using const16 insns. (movsf): Add const16 support. (entry, prologue, epilogue): New. (set_frame_ptr): Add missing mode for unspec_volatile operation. Likewise for subsequent split pattern. * doc/invoke.texi (Option Summary, Xtensa Options): Document new "-mconst16" and "-mno-const16" options. From-SVN: r66809
