Stefano Lattarini 1e44f853 2013-01-12T12:53:21 tests: remove most uses of the AM_PROG_CC_C_O obsolete macro Our NEWS file says its use will no longer be required in Automake 1.13, so better make sure that is actually the case. * Several tests: Adjust.

Stefano Lattarini 34001a98 2013-01-09T23:16:53 compile: use 'compile' script when "-c -o" is used with losing compilers Do so seen when only source files in the "current" directory are present. This commit is part of a series of related changes addressing automake bug#13378 (see also the plan 'PLANS/subdir-objects.txt'). Before this change, Automake-generated C compilation rules mistakenly passed the "-c -o" options combination unconditionally (even to losing compiler) when the 'subdir-objects' was used but sources were only present in the top-level directory. Issue spotted by Nick Bowler: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35> <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44> We fix this by having Automake redefine AC_PROG_CC to take over the role of AM_PROG_CC_C_O and to require the 'compile' script unconditionally (albeit that will continue to be invoked only when inferior compilers are detected). Among other things, this means AM_PROG_CC_C_O explicitly is no longer required; that macro is still supported for backward-compatibility, but calling it is basically a no-op now. This change has some pros and some cons (obviously, we believe the former outweighs the latter). Here are the most relevant ones: + Pros 1: Some logic in the Automake script has been simplified. + Pros 2: That simplification has automatically fixed an actual bug (see Nick's mails referenced above; admittedly, that was present only in corner-case situations, but still); the test 't/ccnoco4.sh', which demonstrated the bug and has been failing so far, now passes. + Pros 3: Things works more "automagically" now (no need to manually add the AM_PROG_CC_C_O macro to configure.ac anymore). * Cons 1: The 'compile' script will be required in all projects using C compilation; this will only be a problem for packages not using '--add-missing'. However, such packages are definitely more rare than the ones using '--add-missing', and adjusting them will be trivial -- just copy the compile script over from the new Automake installation. * Cons 2: The copy & paste of autoconf internals hack this change has introduced in our "rewrite" of AC_PROG_CC is really an egregious abomination. It can only be justified with the fact that we expect future versions of autoconf to implement the semantics we need directly in AC_PROG_CC, so that we'll be able to leverage that (since Automake 1.14 will require the latest Autoconf version released). Now, the detailed list of file-by-file changes ... * automake.in ($seen_cc_c_o): Remove this global variable. (scan_autoconf_traces): Don't set it, and do not trace the 'AM_PROG_CC_C_O' m4 macro. (lang_c_rewrite): Remove, no longer needed. * doc/automake.texi: Adjust expected "autoreconf --install" output in the amhello example. Remove statements about the need for the AM_PROG_CC_C_O macro. Report it is obsolete now. * m4/init.m4: Re-write AC_PROG_CC to append checks about whether the C compiler supports "-c -o" together. These checks have basically been ripped out (with adaptations) from the 'AC_PROG_CC_C_O' macro of Autoconf and ... * m4/minuso.m4 (AM_PROG_CC_C_O): ... this macro of ours, which has thus basically become a no-op. * t/ax/am-test-lib.sh (am_setup_testdir): Also copy the 'compile' script in the test directory; if we don't do so, every test using AC_PROG_CC should call automake with the "--add-missing" option, or copy the 'compile' script itself. * t/cond11.sh: No need to create a dummy 'compile' script: that is already brought in by 'am_setup_testdir()', that is automatically invoked when 'test-lib.sh' is sourced. * t/add-missing.tap: Adjust: we expect the 'compile' script to be required by a mere AC_PROG_CC call now. * t/dist-auxdir-many-subdirs.sh: Likewise. * t/specflg6.sh: Likewise. * t/subobj4.sh: Likewise. * t/cxx-lt-demo.sh: Likewise, and update comments to match. * t/distcom2.sh: Enhance a little. * t/dollarvar2.sh: Adjust. * t/extra-portability.sh: Likewise. * t/libobj19.sh: Likewise. * t/per-target-flags.sh: Likewise. * t/repeated-options.sh: Likewise. * t/subobj.sh: Likewise, and enhance a little. * t/ccnoco2.sh: Remove as obsolete. * t/list-of-tests.mk (handwritten_TESTS): Adjust. (XFAIL_TESTS): Remove 't/ccnoco4.sh'. * NEWS: Update. Signed-off-by: Stefano Lattarini <stefano.lattarini@gmail.com>

Stefano Lattarini 5ddf1007 2012-10-27T16:41:39 tests: prefer including 'test-init.sh' rather than './defs' This is a follow-up to today's commit v1.12.4-22-g0610fc8, "tests: prepare to move ./defs to t/ax/test-init.sh" * All tests: To run the common setup, use the command: . test-init.sh instead of the older, "historical" one: . ./defs || exit 1 Note that the "|| exit 1" wasn't really useful, since the 'errexit' shell flag is in effect in both './defs' and 'test-init.sh', and all the known shells that are good enough to run the automake testsuite do automatically exit with error when a sourced file cannot be found (at least, they do so in non-interactive mode, which is the only mode that concerns us in the testsuite). * t/ax/tap-summary-aux.sh, t/ax/testsuite-summary-checks.sh: Likewise. * gen-testsuite-part: Do the same in the generated tests.

Stefano Lattarini 9a2796ad 2012-06-09T20:49:09 tests: merge, tweak and modernize few test scripts Basically an adjusted-and-improved cherry-pick from Automake-NG commit v1.12.1-343-gff30f83. * t/specflg.sh, t/specflg2.sh, t/specflg3.sh: Merged into ... * t/per-target-flags.sh: ... this test. * t/fo.sh: Remove, its weak grepping checks well superseded by the semantic checks in 't/fort4.sh'. * t/cxxo.sh: Remove, its weak grepping checks well superseded by the semantic checks in 't/cxx-demo.sh'. * t/cxxcpp.sh: Enhance a little. * t/empty.sh: Renamed ... * t/empty-data-primary.sh: ... to this. Add trailing ':' command. * t/empty2.sh, t/empty3.sh, t/empty4.sh: Merged ... * t/empty-sources-primary.tap: ... into this new test. * t/no-outdir-option.sh: Remove. A test to check than an obsolete and now deleted option ("--output-dir") stays deleted is way too much even for the most test-infected person ;-) * t/list-of-tests.mk: Adjust.
