coverage:

# Reset all coverage counts. When coverage is enabled, each time you
# run the program, it adds its execution counts into the profiling
# data files in the build directory. 'make coverage-reset' deletes
# those files, so the counts reported by 'make coverage' start from
# zero again. Note that 'make clean' does this automatically.

### Variables that are useful to override on the command line.
CC = gcc
CXX = g++
CXXFLAGS = -g3 -O2 -Wall -m32

# To produce test coverage reports:
# 1) Build all .o files and executables without optimization and with
#    'COVERAGE=1' on the make command line.
# 2) Run the tests.
# 3) Do 'make coverage'.
# All in one command:
# $ make CFLAGS='-O0' CXXFLAGS='-O0' COVERAGE=1 clean check coverage
COVERAGE=

# A wrapper for running 'make check' targets. This is inserted before
# the test executable name in the commands for 'check' targets. So if
# 'make check' would normally execute some test program with the
# command:
#
#    SOME_ENV_VAR=value ./some-test-executable test-args
#
# then setting TEST_WRAPPER to 'valgrind' (say) would have 'make
# check' run the this command line:
#
#    SOME_ENV_VAR=value valgrind ./some-test-executable test-args
TEST_WRAPPER=

# Arguments to pass to the test programs.
TEST_ARGS=

### Variables used internally by this Makefile.

# The top of the breakpad source tree.
SRC = ../../..

# A list of the executables that we should use the C++ compiler to
# link. GNU make's default executable-from-object rule uses $(CC),
# which doesn't include libstdc++, and perhaps does some other things
# wrong as well. Every executable listed in this variable uses the
# pattern rule provided at the bottom, which links all the
# dependencies using $(CXX). Value accumulated throughout the file.
CPP_EXECUTABLES = 

# Add the names of source files whose coverage you'd like 'make
# coverage' to report on to this variable. Value accumulated
# throughout the file.
