# This Makefile fragment is included from the build-tcg target, once
# for each target we build. We have two options for compiling, either
# using a configured guest compiler or calling one of our docker images
# to do it for us.
#

# The configure script fills in extra information about
# useful docker images or alternative compiler flags.

# Usage: $(call quiet-command,command and args,"NAME","args to print")
# This will run "command and args", and either:
#  if V=1 just print the whole command and args
#  otherwise print the 'quiet' output in the format "  NAME     args to print"
# NAME should be a short name of the command, 7 letters or fewer.
# If called with only a single argument, will print nothing in quiet mode.
