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 (a] collabora.co.uk> 64 # Copyright (c) 2016-2017 The strace developers. 65 # 66 # Copying and distribution of this file, with or without modification, are 67 # permitted in any medium without royalty provided the copyright notice 68 # and this notice are preserved.
