re PR rtl-optimization/83723 (ICE: in gen_rtx_SUBREG, at emit-rtl.c:1010)
PR rtl-optimization/83723
* lra-int.h (lra_substitute_pseudo): Add DEBUG_P argument.
* lra.c (lra_substitute_pseudo): Likewise. If true, use
gen_rtx_raw_SUBREG instead of gen_rtx_SUBREG. Pass DEBUG_P to
recursive calls.
(lra_substitute_pseudo_within_insn): Adjust lra_substitute_pseudo
callers.
* lra-constraints.c (inherit_reload_reg, split_reg): Likewise.
* gcc.dg/pr83723.c: New test.
