# This makefile is normally called by the main Makefile after setting

###########################################################################
# User-customizable variables
###########################################################################

# The following variables could be modified via the command-line of make,
# either with the syntax 'make XYZ=1' or 'XYZ=1 make'

# To see the actual commands launched by make instead of shortened versions,
# set this variable to 1 (or any non-empty value):
VERBOSE ?=

# If set to 1 (or non-empty) then *.ml files corresponding to *.ml4 files
# will be generated in a human-readable format rather than in a binary format.
READABLE_ML4 ?=

# When non-empty, a time command is performed at each .v compilation.
# To collect compilation timings of .v and import them in a spreadsheet,
# you could hence consider: make TIMED=1 2> timings.csv
TIMED ?=

# When $(TIMED) is set, the time command used by default is $(STDTIME)
# (see below), unless the following variable is non-empty. For instance,
# it could be set to "'/usr/bin/env time -p'".
TIMECMD ?=

# When non-empty, -time is passed to coqc and the output is recorded
# in a timing file for each .v file.  If set to "before" or "after",
# the file name for foo.v is foo.v.$(TIMING)-timing; otherwise, it is
# foo.v.timing
TIMING ?=

# Non-empty skips the update of all dependency .d files:
NO_RECALC_DEPS ?=

# Non-empty runs the checker on all produced .vo files:
VALIDATE ?=

# Output file names for timed builds
TIME_OF_BUILD_FILE               ?= time-of-build.log
