* TODO: Remove already done things. Update the part
about finding tools for the target.
2003-11-24 Paolo Bonzini <bonzini@gnu.org>
* lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
AC_DIR_HEADER): Make wording more consistent.
* lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2,
AC_MINGW32): Explain the transition better.
* lib/autoconf/types.m4 (AC_INT_16_BITS,
AC_LONG_64_BITS): Explain the transition better.
2003-11-24 Paolo Bonzini <bonzini@gnu.org>
* doc/autoconf.texi (Obsoleting Macros): Don't
document the third parameter of AU_DEFUN.
* lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.
(AU_DEFUN): Remove the third parameter, it was not used.
Use AC_DEFUN directly, not AU_DEFINE.
* lib/autoconf/status.m4 (AC_LINK_FILES): Move the message
into the expanded body, consistently with other macros
such as AC_USG.
* lib/autoconf/autoconf.m4: Include it.
* lib/autoconf/functions.m4: Use AN_FUNCTION for all the functions
that were listed in the original autoscan.list.
* lib/autoconf/headers.m4: Similarly with headers.
* lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
(.m4.m4f): Don't pass --prepend-include, since that's done by
tests/autom4te itself.
* lib/autoscan/Makefile.am: Include freeze.mk.
(autoscan.list): New target --this file is no longer a source.
(autoscan.pre): New file.
(&file_name_is_absolute): New, wrappers around routines from
File::Spec.
Use and export them.
(&find_configure_ac): Optionally take a directory where to look at.
* bin/autoreconf.in (&parse_args): Trim the configure.ac part of
the arguments.
Default @ARGV to `.', not find_configure_ac.
(&autoreconf): Argument is a directory.
Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
* doc/autoconf.texi (autoreconf Invocation): Update.
(&handle_m4): Use it.
* tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
warnings are issued at each run.
* tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
is in the src tree.
(Macro Index): Rename as...
(Autoconf Macro Index): this.
(M4 Macro Index): New appendix.
(Programming in M4): New chapter.
Define M4sugar, M4sh, m4_pattern_forbid, and m4_pattern_allow.
(Quoting): Rename as...
(M$ Quotation): this.
Be part of `Programming in M4).
values.
(%needed_macros): New.
(&check_configure_ac): New. Call it.
(&output_libraries): Eve out from &output_programs.
(&print_unique): For the time being register in %needed_macros
only argument less macros.
(AC_PROG_CC, AC_PROG_CXX): Use it.
(AC_PROG_CC_STDC): Be sure to remove tmp files.
* tests/compile.at (AC_TRY_LINK_FUNC): Don't use exit to test it,
since it produces a prototype which conflicts with the one
computed by _AC_PROG_CXX_EXIT_DECLARATION.
* tests/semantics.at (AC_CHECK_FUNCS, AC_HAVE_FUNCS): Likewise.
(AC_HAVE_FUNCS): Test AC_HAVE_FUNCS!
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.
value of the VARIABLE argument when looking for executables, we
need to set it to the correct value from AC_CHECK_TOOL when not
just passing on the incoming VARIABLE directly.
(AC_CHECK_TOOLS, AC_PATH_TOOL): Likewise.
AC_LANG_COMPILER by the way of AC_COMPILE_IFELSE etc.
* acspecific.m4 (_AC_EXEEXT): Use _AC_LINK_IFELSE, not
AC_LINK_IFELSE to avoid AC_REQUIREing AC_PROG_CC which precisely
requires _AC_EXEEXT.
Don't run _AC_CYGWIN, _AC_MINGW32, _AC_EMXOS2.
* aclang.m4 (_AC_PROG_F77_G): Use _AC_COMPILE_IFELSE, not
AC_COMPILE_IFELSE.
(_AC_LANG_COMPILER_WORKS): Use _AC_LINK_IFELSE, not
AC_LINK_IFELSE.
* acgeneral.m4 (_AC_DEFUN_PRO, _AC_DEFUN_EPI): Keep a stack of
macro expansions, _AC_EXPANSION_STACK.
Use `_AC_EXPANDING(FOO)' to record the fact that `FOO' is being
expanded.
(_AC_REQUIRE): Diagnose required macros which are already being
expanded.
Record in _AC_EXPANSION_STACK the AC_REQUIRE calls.
(_AC_EXPANSION_STACK_DUMP): New macro.
(_AC_DIVERT(PARSE_ARGS)): this. Adjust dependencies.
(AC_ARG_WITH): Remove spurious newline.
(AC_ARG_VAR): No longer save precious variables in
ac_configure_args, rather snapshot them twice (one kept
unmodified, another one to be written to/overwritten by the cache
file).
(AC_CACHE_SAVE): Let the cache variables named `ac_cv_env_*'
be overwritten when loading the cache (i.e., don't use the
: ${foo=...} trick).
(_AC_ARG_VAR_VALIDATE): Compare the two snapshots of the precious
variables.
(_AC_INIT_PREPARE): Call it after having loaded the cache file.
Macros): Don't give boring internal details.
(Language Choice): Typo.
(Limitations of Builtins): Some about `!', `set', `$@'.
(Coding Style): Some about $[@] quotation.
Some about cross-compilation.
AC_CONFIG_COMMANDS, AC_CONFIG_FILES): Use a shell variable instead
of an m4 variable to store what must be done, so that sh
conditionals are honored.
(_AC_OUTPUT_LINKS, _AC_OUTPUT_HEADERS,
_AC_OUTPUT_COMMANDS, _AC_OUTPUT_FILES): Adjust.
* tests/semantics.m4: Test the four AC_CONFIG sisters.
* doc/autoconf.texi (Configuration Actions): Promote the use of
literals, show it works properly with sh conditionals.
