* config/sparc/sparc.h (FIXED_REGISTERS, CONDITIONAL_REGISTER_USAGE):
Allow the user to override call-used/fixed state of %g2-5
registers from the command line (with the exception of %g4 for
embedded model).
(REG_LEAF_ALLOC_ORDER): Move %g1 and %g4-7 registers to front, so that
there is a higher chance of having a leaf function.
(MACHINE_STATE_SAVE, MACHINE_STATE_RESTORE): Provide separate macros
for ARCH64 which has %ccr register.
* config/sparc/sparc.md (return_losum_si, return_losum_di): New
patterns.
* config/sparc/sparc.c (eligible_for_epilogue_delay): For the return
insn accept into delay slot any insn which does not use %[ol]
registers. Accept some LO_SUM and shift left by 1 for the normal
restore case.
(output_function_epilogue): Likewise.
(epilogue_renumber): Added argument which inhibits any renumbering
and just tests if the rtx does not use any %[ol] registers.
(output_return): Reflect above change.
