* doc/autoconf.texi (Limitations of Usual Tools) <expr>: More
information, thanks to Paul Berrevoets, Paul Eggert and David
Morgan.
* sh.m4 (_AS_EXPR_PREPARE): New.
(AS_DIRNAME): Use it.
* tests/atgeneral.m4 (AT_INIT): Initialize AT_banner_ordinal.
Execute the epilogue of the tests only if a test was run.
Don't built the value of `at_tests_all' by a for loop: expand
AT_TESTS_ALL.
(AT_SETUP): Build AT_TESTS_ALL.
(AT_BANNER): New.
Adjust all the former banners to use it.
(AT_CHECK): Don't trace the decoding of $?.
* tests/atgeneral.m4 (_m4_divert(SUITE_PRO)): Remove, replaced
by...
(_m4_divert(DEFAULT), _m4_divert(OPTIONS), _m4_divert(HELP))
(_m4_divert(SETUP)): these.
(_m4_divert(SUITE_EPI)): Rename as...
(_m4_divert(TAIL)): this.
(AT_INIT): Adjust to the new diversions.
Insert the magic number.
Accept test groups as cli argument.
List the test groups.
Rename TESTS, test, and tests as at_tests_all, at_test, and
at_tests.
Have the debug scripts pass options to test suite.
Remove their banner.
* tests/atspecific.m4: Don't divert to 0.
* suite.at: Don't insert the magic number.
* tests/atgeneral.m4 (_m4_divert(SUITE_PRO), _m4_divert(TESTS))
(_m4_divert(SUITE_EPI), _m4_divert(TEST)): New diversions.
Push the first two diversions.
(AT_INIT): Don't.
(AT_INIT, AT_SETUP, AT_CLEANUP): Adjust to use the named
diversions.
(AT_CLEANUP_FILES): New macros.
(AT_SETUP, AT_CHECK, AT_CLEANUP): Use them.
(AT_CHECK): Fix a use of at_verbose.
* tests/atspecific.m4 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER)
(AT_CHECK_CONFIGURE): New macros.
* tests/atgeneral.m4 (AT_SETUP, AT_CLEANUP): No longer handle
at_stop_on_error.
(AT_INIT): After having checked whether the test failed, break out
of the loop if requested (-e).
specific test.
* tests/atgeneral.m4 (AC_INIT) <at_debug>: New variable, new
option, -d, to disable the creation of the debug scripts (when
testsuite was already launched from one).
<at_test_count>: Really compute it instead of using the number of
the last test run.
As a known side effect, currently any code outside
AT_SETUP/AT_CLEANUP is discarded.
* acgeneral.m4 (_m4_divert(KILL)): Move to...
* m4sugar.m4: here.
* tests/atgeneral.m4 (AT_INIT): Use m4_divert_push/pop instead of
m4_divert.
Put all the tests inside a for;case.
Define TESTS.
(AT_SETUP, AT_CLEANUP): Open/close each case.
* tests/atgeneral.m4: Import M4sh.
Adjust the differences on the names of the builtins (define etc.).
(AT_CASE): Remove, use m4_case.
(AT_SETUP): Don't use `AT_group_description', `$1' is OK.
* tests/atspecific.m4 (m4_for, m4_foreach): Remove, use those of
M4sugar.
* tests/m4sugar.at: Strengthen the quotation and adjust to the new
macro names.
* tests/m4sh.at: Ditto.
* tests/torture.at: Ditto.
* tests/base.at: Ditto.
* m4sh.m4: Import M4sugar.
* autoconf.m4: Don't import M4sugar, M4sh does.
* acgeneral.m4 (_AC_RUN_IFELSE): Instead of canceling the output
of the test program, save it into the log.
Save the exit status, and report it in the log when non zero.
Just use `(./conftest)' instead of `(./conftest; exit)'.
before high level ones.
* tests/semantics.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
(missing templates): Move to...
* tests/torture.at: here.
Reorder the file so that the torture test is last.
* tests/semantics.at (AC_TRY_LINK_FUNC, AC_PROG_CPP with warnings)
(AC_PROG_CPP without warnings): Move to...
* tests/compile.at: here, new file.
* tests/suite.at: Run `torture' and then `compile' before
`semantics'.
From Paul Eggert and Johan Danielsson.
* doc/autoconf.texi (Limitations of Usual Tools) <sed>:
Reorganize. Document this issue.
* autoupdate.sh (dir): Use `,' as separator instead of `/'
* autoreconf.sh: Likewise.
* autoupdate.sh: Ditto.
(_AC_SYS_LARGEFILE_TEST_INCLUDES): this.
(AC_SYS_LARGEFILE_MACRO_VALUE): Use AC_LANG_PROGRAM instead of
_AC_SYS_LARGEFILE_SOURCE, i.e., don't pass
_AC_SYS_LARGEFILE_TEST_INCLUDES by default: this isn't desirable
when checking for fseeko.
(AC_SYS_LARGEFILE): Pass AC_SYS_LARGEFILE_TEST_INCLUDES to
_AC_SYS_LARGEFILE_MACRO_VALUE, since it no longer does this for us.
* tests/tools.at (Forbidden tokens): Test m4_token_allow.
* m4sugar.m4 (m4_file_append, m4_token_allow): New macros.
* autoconf.sh (task script): Pass `tmp' and `verbose' to
finalize.awk.
(finalize.awk::check_patterns): Eve out from the body.
(finalize.awk): Read `$tmp/tokens_allowed', and don't complain for
these exceptions.
whether fseeko and ftello are properly declared.
* acfunctions.m4 (AC_FUNC_FSEEKO): New macro, which worries about
fseeko (and presumably ftello). Do not set _XOPEN_SOURCE; that
causes too many problems in practice.
* acfunctions (fteelo, fseeko): Trigger AC_FUNC_FSEEKO.
* doc/autoconf.texi: Adjust.
Be sure to read this file if you're using a non released Autoconf.
* tests/tools.at (Syntax of the scripts): The non built tools are
in `$top_srcdir', not `..'.
(autoconf --trace): When using `-i' we need the src tree, not the
build tree.
* m4sugar.m4 (_m4_require): $2 defaults to $1.
Rename as...
(m4_require): this.
* acgeneral.m4 (_AC_REQUIRE): Remove, use m4_require if you want
to get into the gory details.
The main difference is that the former requires AC_LANG_COMPILER.
* aclang (AC_LANG_PREPROC, AC_LANG_PREPROC(C), AC_LANG_PREPROC(C++))
(AC_LANG_PREPROC(Fortran 77), AC_LANG_PREPROC_REQUIRE): New
macros. Issue a warning when looking for the Fortran 77
preprocessor instead of an error.
(AC_LANG_COMPILER): Check that it is run before the corresponding
AC_LANG_PREPROC.
(AC_PROG_C
(AC_LANG_COMPILER_REQUIRE): Don't call directly
AC_LANG_COMPILER(_AC_LANG), rather invoke AC_LANG_COMPILER so that
the generic code in AC_LANG_COMPILER is run.
(AC_REQUIRE_CPP): Use AC_LANG_PREPROC_REQUIRE.
(AC_PROG_CC, AC_PROG_CXX): Don't require being run before the
corresponding AC_LANG_PREPROC: AC_LANG_COMPILER does it.
Propagate AC_LANG_PREPROC_REQUIRE.
* acgeneral.m4 (AC_TRY_CPP, AC_EGREP_CPP): Use it instead of
AC_REQUIRE_CPP.
* acspecific.m4 (_AC_DECL_YYTEXT, AC_PATH_X): Don't
AC_REQUIRE_CPP, inner macro will do it.
* aclang.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_STRINGIZE)
(AC_C_PROTOTYPES): Likewise.
(AC_C_STRINGIZE): Yeeks! The body of AC_CACHE_CHECK was not
quoted. Use @%:@ do assist Emacs.
For some reason (don't ask), this revamping revealed that
AC_PROG_CC_STDC, because of the `break', does not clean its tmp
files.
* aclang.m4 (AC_PROG_CC_STDC): Extract the creation of conftest.c
out of AC_COMPILE_IFELSE.
Be sure to clean the tmp files.
