VALGRIND_ENABLED is defined and substituted, and corresponds to 19# the value of the --enable-valgrind option, which defaults to being 20# enabled if Valgrind is installed and disabled otherwise. Individual 21# Valgrind tools can be disabled via --disable-valgrind-<tool>, the 22# default is configurable via the AX_VALGRIND_DFLT command or is to use 23# all commands not disabled via AX_VALGRIND_DFLT. All AX_VALGRIND_DFLT 24# calls must be made before the call to AX_VALGRIND_CHECK. 25# 26# If unit tests are written using a shell script and automake's 27# LOG_COMPILER system, the $(VALGRIND) variable can be used within the 28# shell scripts to enable Valgrind, as described here: 29# 30# https://www.gnu.org/software/gnulib/manual/html_node/Running-self_002dtests-under-valgrind.html 31# 32# Usage example: 33# 34# configure.ac: 35# 36# AX_VALGRIND_DFLT([sgcheck], [off]) 37# AX_VALGRIND_CHECK 38# 39# Makefile.am: 40# 41# @VALGRIND_CHECK_RULES@ 42# VALGRIND_SUPPRESSIONS_FILES = my-project.supp 43# EXTRA_DIST = my-project.supp 44# 45# This results in a "check-valgrind" rule being added to any Makefile.am 46# which includes "@VALGRIND_CHECK_RULES@" (assuming the module has been 47# configured with --enable-valgrind). Running `make check-valgrind` in 48# that directory will run the module's test suite (`make check`) once for 49# each of the available Valgrind tools (out of memcheck, helgrind and drd) 50# while the sgcheck will be skipped unless enabled again on the 51# commandline with --enable-valgrind-sgcheck. The results for each check 52# will be output to test-suite-$toolname.log. The target will succeed if 53# there are zero errors and fail otherwise. 54# 55# Alternatively, a "check-valgrind-$TOOL" rule will be added, for $TOOL in 56# memcheck, helgrind, drd and sgcheck. These are useful because often only 57# some of those tools can be ran cleanly on a codebase. 58# 59# The macro supports running with and without libtool. 60# 61# LICENSE 62# 63# Copyright (c) 2014, 2015, 2016 Philip Withnall <philip.withnall@collabora.co.uk> 64# 65# Copying and distribution of this file, with or without modification, are 66# permitted in any medium without royalty provided the copyright notice 67# and this notice are preserved.
