# CP_HOST_STAGE_N template: arg 1 is the N we're promoting *from*, arg
# 2 is N+1. Must be invoked to promote target artifacts to host
# artifacts for stage 1-3 (stage0 host artifacts come from the
# snapshot).  Arg 3 is the triple we're copying FROM and arg 4 is the
# triple we're copying TO.
#
# The easiest way to read this template is to assume we're promoting
# stage1 to stage2 and mentally gloss $(1) as 1, $(2) as 2.

define CP_HOST_STAGE_N

# Host libraries and executables (stage$(2)/bin/rustc and its runtime needs)

# Note: $(3) and $(4) are both the same!

# Subtle: We do not let the shell expand $(CORELIB_DSYM_GLOB) directly rather
# we use Make's $$(wildcard) facility. The reason is that, on mac, when using
# USE_SNAPSHOT_CORELIB, we copy the core.dylib file out of the snapshot.
# In that case, there is no .dSYM file.  Annoyingly, bash then refuses to expand
# glob, and cp reports an error because libcore-*.dylib.dsym does not exist.
# Make instead expands the glob to nothing, which gives us the correct behavior.
# (Copy .dsym file if it exists, but do nothing otherwise)
