2002-04-19real.h: Define REAL_VALUE_TYPE_SIZE as 96 or 160, as appropriate.Zack Weinberg1-76/+27
* real.h: Define REAL_VALUE_TYPE_SIZE as 96 or 160, as appropriate. Document need for extended precision even when MAX_LONG_DOUBLE_TYPE_SIZE is smaller. Define REAL_WIDTH here, based on REAL_VALUE_TYPE_SIZE. Use REAL_WIDTH to size REAL_VALUE_TYPE. Define CONST_DOUBLE_FORMAT here. Use #error instead of relying on later syntax error when REAL_WIDTH > 5. * real.c: Define NE based only on whether or not we have a full 128-bit extended type (not INTEL_EXTENDED_IEEE_FORMAT). Require sizeof(REAL_VALUE_TYPE) == 2*NE. Unconditionally define GET_REAL and PUT_REAL as simple memcpy operations; no need to byteswap or round. Use #error instead of #ifdef-ing out the entire file, for prompt error detection. * rtl.c, gengenrtl.c: No need to calculate CONST_DOUBLE_FORMAT here. From-SVN: r52502

(print_operand): Delete huge commented-out chunk. Use REAL_VALUE_TO_DECIMAL. * config/1750a/1750a-protos.h: Delete prototypes of deleted functions. * config/convex/convex.h: Always set TARGET_FLOAT_FORMAT to IEEE_FLOAT_FORMAT. * config/i370/i370.h (PRINT_OPERAND [TARGET_HLASM version]): Use REAL_VALUE_TO_DECIMAL as ELF version does. * config/m88k/m88k.c (real_power_of_2_operand, legitimize_operand): Take the REAL_VALUE_TYPE and/or union real_extract out of the union; run the input through REAL_VALUE_TO_TARGET_DOUBLE, then plug the pair of longwords from that into the union. * config/pdp11/pdp11.c (output_move_double): Rearrange parentheses to make automatic indenter happy. * doc/tm.texi (Cross-compilation): Rename node to "Floating Point" and rewrite to describe current situation. Also adjust documentation of REAL_VALUE_TO_TARGET_SINGLE and friends to match code. * doc/rtl.texi: Adjust cross reference. From-SVN: r51210
