14161 * config/fp-bit.c (EXTENDED_FLOAT_STUBS): If EXTENDED_FLOAT_STUBS
14162 is defined, define all of the XF/TF functions that might be
14163 generated that we don't have code for yet.
14165 * i960/t-(vxworks960,960bare): (LIB2FUNCS_EXTRA): Make and
14166 compile xp-bits.c that defines EXTENDED_FLOAT_STUBS.

14186 Tue Apr 2 13:52:30 1996 Jeffrey A. Law <law@cygnus.com>
14188 * h8300.md (movqi_internal): Remove useless alternative(s). Fix
14189 lengths and simplify by reordering remaining alternatives.

14191 (movsi_h8300h, movsf_h8300h): Likewise.
14193 * h8300/h8300.c (extra_pop): Remove unused variable.

14197 (function_epilogue): Likewise.
14198 (function_arg): Never pass unnamed arguments in registers.
14199 * h8300.h (LONG_LONG_TYPE_SIZE): Use 64bits when ints are 32bits.
14200 (SETUP_INCOMING_VARARGS): Remove definition.

14204 * fixincludes: Fix signal prototype on SunOS to avoid pedantic C++
14207 Mon Apr 1 16:16:34 1996 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
14209 * expr.c (get_inner_reference): When finding mode to access bitfield
14210 that ends up properly aligned, use mode class of its type unless
14211 type's mode was BLKmode.
14213 Mon Apr 1 13:45:30 1996 Jeffrey A. Law <law@cygnus.com>
14215 * h8300.c (interrupt_handler): Renamed from pragma_interrupt.
14216 All references changed.
14217 (function_prologue): Set interrupt_handler if the current
14218 function has the "interrrupt-handler" attribute.
14219 (small_call_insn_operand): New function.
14220 (h8300_interrrupt_function_p): New function.
14221 (h8300_funcvec_function_p): New function.

14223 * h8300.h (VALID_MACHINE_DECL_ATTRIBUTE): Define.
14224 * h8300.md (call insns): Handle calls through the
14225 function vector. Indirect calls and calls through
14226 the function vector have a length of two bytes.
14228 See ChangeLog.10 for earlier changes.
14230 Use a consistent time stamp format in ChangeLog entries.
14231 Not everyone has Emacs 20 yet, so stick with Emacs 19 format for now.
