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

###########################################################################
# 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 ?=

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

# When non-empty, passed as extra arguments to coqtop/coqc:
COQUSERFLAGS ?=

# Option for changing sorting of timing output file
TIMING_SORT_BY ?= auto
# Option for changing the fuzz parameter on the output file
TIMING_FUZZ ?= 0
# Option for changing whether to use real or user time for timing tables
TIMING_REAL?=
# Option for including the memory column(s)
TIMING_INCLUDE_MEM?=
# Option for sorting by the memory column
TIMING_SORT_BY_MEM?=
# Output file names for timed builds
TIME_OF_BUILD_FILE               ?= time-of-build.log
TIME_OF_BUILD_BEFORE_FILE        ?= time-of-build-before.log
TIME_OF_BUILD_AFTER_FILE         ?= time-of-build-after.log
TIME_OF_PRETTY_BUILD_FILE        ?= time-of-build-pretty.log
TIME_OF_PRETTY_BOTH_BUILD_FILE   ?= time-of-build-both.log
TIME_OF_PRETTY_BUILD_EXTRA_FILES ?= - # also output to the command line

AFTER ?=
