# TARGET_STAGE_N template: This defines how target artifacts are built
# for all stage/target architecture combinations. The arguments:
# $(1) is the stage
# $(2) is the target triple
# $(3) is the host triple
# Every recipe in TARGET_STAGE_N outputs to $$(TLIB$(1)_T_$(2)_H_$(3),
# a directory that can be cleaned out during the middle of a run of
# the get-snapshot.py script. Therefore, every recipe needs to have
# an order-only dependency either on $(SNAPSHOT_RUSTC_POST_CLEANUP) or
# on $$(TSREQ$(1)_T_$(2)_H_$(3)), to ensure that no products will be
# put into the target area until after the get-snapshot.py script has
# had its chance to clean it out; otherwise the other products will be
# inadvertantly included in the clean out.
