final.c (output_in_slot): New global variable.
* final.c (output_in_slot): New global variable.
(final_scan_insn): Add new state '2' to the 'nopeepholes' parameter.
Pass 2 as 'nopeepholes' to self for insns in a SEQUENCE. Set
'output_in_slot' before invoking output_asm_insn.
(output_asm_insn): Add a space after the tab if 'output_in_slot'
is set.
* config/sparc/sparc.c (output_return): Pass 2 as 'nopeepholes' to
final_scan_insn.
(output_sibcall): Likewise.
