	PR fortran/41807
	* trans-const.c (gfc_conv_const): Set se->expr to a constant on error.

From-SVN: r154690

	* cfgexpand (n_stack_vars_conflict): New static variable.
	(triangular_index): Reduce likelyhood of overflow by performing
	the division before the multiplication.
	(resize_stack_vars_conflict): Call fatal_error if overflow
	occurred in triangular_index.  Update n_stack_vars_conflict.

From-SVN: r154689

	PR rtl-opt/38582
	* regrename.c (struct du_head): New members id, conflicts,
	hard_conflicts and cannot_rename.
	(enum scan_actions): Remove terminate_all_read and
	terminate_overlapping_read; add mark_all_read.
	(scan_actions_name): Likewise.
	(du_head_p): New typedef.  Define a vector type for it.
	(id_to_chain): New static variable.
	(note_sets, clear_dead_regs): Delete functions.
	(free_chain_data): New function.
	(merge_overlapping_regs): Simply walk the conflicts bitmap.
	Remove argument B, all callers changed.
	(regrename_optimize): Allocate id_to_chain.  Ignore chains that have
	the cannot_rename bit set.  Update regno and nregs of a renamed chain.
	Call free_chain_data when done.
	(do_replace): Remove death notes when the renamed reg is set in the
	last insn; add them if not.
	(mark_conflict, note_sets_clobbers): New static function.
	(fail_current_block, current_id, open_chains_set, live_hard_regs): New
	static variables.
	(scan_rtx_reg): Keep track of conflicts between chains, and between
	chains and hard regs.  Don't terminate chains when we find a read we
	can't handle, mark it unrenameable instead.  For terminate_write,
	terminate chains that are written with an exact match or a superset
	of registers.  Set fail_current_block if multi-word lifetimes are too
	complex to handle.
	(scan_rtx_address): Use mark_all_read instead of terminate_all_read.
	(build_def_use): Initialize current_id, live_chains and live_hard_regs;
	free memory for them when done.
	Rearrange the steps so that earlyclobbers are noted before reads
	are processed.  Add new steps to keep track of hard register lifetimes
	outside insn operands.
