* config/mips/tm-irix3.h: Clean up, use tm-bigmips.h and redefine the necessary bits. * findvar.c (value_from_register): Fix uninitialized first_addr which caused problems with assignment of doubles to register variables on some targets. * mipsread.c: Remove TM_FILE_OVERRIDE, include tm.h and provide the missing mips definitions if necessary. Fix handling of double register variables for mips targets and big endian hosts. These patches are from Paul Flinders <ptf@delcam.co.uk>. * config/mips/tm-mips.h: Increase MAX_REGISTER_{RAW,VIRTUAL}_SIZE to 8 bytes for doubles. * config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE): New macro for conversion of type held in multiple registers to host format. * config/mips/tm-mips.h (REGISTER_CONVERT_FROM_TYPE): New macro, companion to REGISTER_CONVERT_TO_TYPE. * config/mips/tm-mips.h (EXTRACT_RETURN_VALUE, STORE_RETURN_VALUE): Convert to function calls. * config/mips/tm-mips.h (FIX_CALL_DUMMY): New code for big endian mips targets. * mips-tdep.c (mips_print_register): Raw buffer now needs just MAX_REGISTER_RAW_SIZE bytes. * mips-tdep.c (mips_print_register): Use REGISTER_CONVERT_TO_TYPE (if defined) for doubles. * mips-tdep.c: (mips_extract_return_value, mips_store_return_value): New functions, take care of REGISTER_CONVERT_TO/FROM_TYPE. * valops.c (value_assign): Use REGISTER_CONVERT_TO_TYPE if defined. * findvar.c (value_from_register): Use REGISTER_CONVERT_TO_TYPE if defined.
