From: Richard Kenner Date: Mon, 23 Aug 1993 22:45:15 +0000 (-0400) Subject: (MOTOROLA): Define this. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=9161998e10a87d337e114ff78ded17e9655a05d9;p=gcc.git (MOTOROLA): Define this. (VERSADOS): This the name of the DPX2 assembler. Define this in case. (USG): Define this. (SGS_NO_LI): define this to suppress jump table usage. (TARGET_DEFAULT): Define this to 3 inside the conditional USE_GAS since bitfields do not work a clean way on DPX2. (EXTRA_SECTIONS, EXTRA_SECTION_FUNCTIONS, SELECT_SECTION, SELECT_RTX_SECTION): #undef these. (READONLY_DATA_SECTION): Define to data_section. (*_ASM_OP, ASM_OUTPUT_*): Define these accordingly to the native assembler syntax. (LONG_DOUBLE_TYPE_SIZE): Set to 64 to not use XFmode. (REAL_ARITHMETIC): Define this to use the software floating point emulator. (JUMP_TABLES_IN_TEXT_SECTION): Define this to 1. (FUNCTION_PROLOGUE, FUNCTION_EPILOGUE): Override m68k.h default. (ASM_OUTPUT_ASCII): add a new variable to take care of the lentgh of the operand field which must be < 80 chars. (PRINT_OPERAND_ADDRESS): Override m68k.h default. (PUT_SDB_TYPE): Output type in decimal. (PUT_SDB_FUNCTION_[START|END]): Override sdbout.c default. (PUT_SDB_BLOCK_[START|END]): Override sdbout.c default.
