This is a major redesign a modernization of Sysprof. The core data structures and design are largely the same, but it has been ported to Gtk3 and has lots of additions that should make your profiling experience smoother. Especially for those that are new to profiling. There are some very simple help docs added, but we really need the experts to come in and write some documentation here.

# SYNOPSIS
|
|
#
|
|
# AX_CHECK_ENABLE_DEBUG([enable by default=yes/info/profile/no], [ENABLE DEBUG VARIABLES ...], [DISABLE DEBUG VARIABLES NDEBUG ...], [IS-RELEASE])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check for the presence of an --enable-debug option to configure, with
|
|
# the specified default value used when the option is not present. Return
|
|
# the value in the variable $ax_enable_debug.
|
|
#
|
|
# Specifying 'yes' adds '-g -O0' to the compilation flags for all
|
|
# languages. Specifying 'info' adds '-g' to the compilation flags.
|
|
# Specifying 'profile' adds '-g -pg' to the compilation flags and '-pg' to
|
|
# the linking flags. Otherwise, nothing is added.
|
|
#
|
|
# Define the variables listed in the second argument if debug is enabled,
|
|
# defaulting to no variables. Defines the variables listed in the third
|
|
# argument if debug is disabled, defaulting to NDEBUG. All lists of
|
|
# variables should be space-separated.
|
|
#
|
|
# If debug is not enabled, ensure AC_PROG_* will not add debugging flags.
|
|
# Should be invoked prior to any AC_PROG_* compiler checks.
|
|
#
|
|
# IS-RELEASE can be used to change the default to 'no' when making a
|
|
# release. Set IS-RELEASE to 'yes' or 'no' as appropriate. By default, it
|
|
# uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE
|
|
# macro, there is no need to pass this parameter.
|
|
#
|
|
# AX_IS_RELEASE([git-directory])
|
|
