Author: jsm28 Date: Sat Dec 16 19:24:56 2006 New Revision: 119967 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=119967 Log: 2006-12-16 Joseph Myers <[EMAIL PROTECTED]> David Edelsohn <[EMAIL PROTECTED]> PR target/24036 * doc/tm.texi (HARD_REGNO_NREGS_HAS_PADDING, HARD_REGNO_NREGS_WITH_PADDING): Document new target macros. * defaults.h (HARD_REGNO_NREGS_HAS_PADDING, HARD_REGNO_NREGS_WITH_PADDING): Define. * config/i386/i386.h (HARD_REGNO_NREGS_HAS_PADDING, HARD_REGNO_NREGS_WITH_PADDING): Define. * rtlanal.c (subreg_regno_offset, subreg_offset_representable_p): Use new macros to detect modes with holes; do not look at integer units. (subreg_offset_representable_p): Check for and disallow cases where the modes use different numbers of bits from registers. * config/rs6000/rs6000.c (rs6000_emit_move): Handle TFmode constant for soft-float. (rs6000_hard_regno_nregs): Use UNITS_PER_FP_WORD for e500 GPRs containing doubles. (rs6000_split_multireg_move): Use DFmode reg_mode for TFmode moves in E500 double case. * config/rs6000/rs6000.md (movtf): Allow soft-float. (movtf_softfloat): New.
