11 # This is the compile-time target-triple for the compiler. For the compiler at
12 # runtime, this should be considered the host-triple. More explanation for why
13 # this exists can be found on issue #2400
16 # The standard libraries should be held up to a higher standard than any old
17 # code, make sure that these common warnings are denied by default. These can
18 # be overridden during development temporarily. For stage0, we allow warnings
19 # which may be bugs in stage0 (should be fixed in stage1+)

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