* config/avr/avr.c (out_adj_frame_ptr): Make "frame pointer change too big for -mtiny-stack" a warning, if larger than 63. (out_set_stack_ptr): Change the logic so -mno-interrupts is always safe to use on possible future devices. (function_prologue): Write SPH before SPL, for consistency. If interrupt_func_p true, we know we have enabled interrupts. (avr_num_arg_regs): New function. Round up to even number of bytes if no -mpack-args or if calling a libgcc function. (function_arg, function_arg_advance): Use it. (output_movsisf, ashlsi3_out, ashrsi3_out, lshrsi3_out): Output "movw" if available. (out_tsthi, out_tstsi, ashlqi3_out, lshrqi3_out): Change uses of TEST_HARD_REG_CLASS macro to test_hard_reg_class function. (asm_output_section_name): Add blanks for consistent output. (encode_section_info): Set TREE_READONLY for progmem data to avoid gas warnings about changed section attributes. (avr_hard_regno_mode_ok): Force non-QImode data to start in even numbered registers on devices with "movw". * config/avr/avr.h (MASK_*): Define bits for target_flags. (TARGET_SWITCHES): Mark help strings for translation. Add new -mpack-args and -menhanced switches. (TARGET_OPTIONS): Mark help strings for translation. (progmem_section): Add section attributes. * config/avr/avr.md (*movhi, call_insn, call_value_insn): Output "movw" if available. (mulqi3, mulqihi3, umulqihi3, mulhi3, *tablejump_enh): New patterns. * config/avr/libgcc.S (_mulqi3, _divqi3): Update to the new call convention (arguments aligned on even registers). (_cleanup, _exit): Make weak symbols libc can override. From-SVN: r34847 |
