xine-lib/m4/optimizations.m4, branch 1.2.4

RIP: AC_OPTIMIZATIONS

2007-05-08T04:03:41+00:00

-- Removed m4/optimizations.m4, and along with it, AC_OPTIMIZATIONS.
-- Stripped down, cleaned up, and merged the former together with other compiler
   characteristic checks.
-- Do not set any optimization flags into CFLAGS.  Update all Makefile.am's with
   proper AM_CFLAGS, AM_CPPFLAGS, AM_LDFLAGS, etc. to set up optimization flags,
   usually from DEFAULT_OCFLAGS.
-- Start cleaning up CFLAGS/CPPFLAGS stuff in Makefile.am's all over the place.
-- Correct a number of places where CFLAGS itself was being mangled in
   Makefile to on-the-fly adjust optimizations to work around compiler bugs.
   This stuff is now done correctly.
-- The run of automake from autogen.sh is now clean of warnings.
-- Cleaned out some (now) dead macros from m4/_xine.m4
-- Mac OS X intel builds out-of-the-box now -- dropped optimization on
   post/deinterlace/plugins/kdetv-greedyh to O1_CFLAGS.
-- OBJCFLAGS is now getting set correctly everywhere that it needs to be
-- Various other miscellaneous cleanups all over

More build cleanups

2007-05-05T01:55:20+00:00

-- Pull AC_PROG_OBJC and AC_PROG_OBJCPP from autoconf 2.61, but use the local
   versions only if they're not defined by the version of autoconf in use.
-- Always call AC_PROG_OBJC since there's no harm in doing so.  It'll fail most
   of the time, but it's cleaner than adding yet another $host_os check
-- Remove -DCONFIG_DARWIN from CPPFLAGS since it was added specifically for
   ffmpeg when ffmpeg was built using xine's built infrastructure rather than
   its own.  It's now defined properly where its needed elsewhere.
-- Set host_or_hostalias early rather than later in the middle of xv checking
   since a bunch of other stuff depends on it too.

Begin cleaning up compiler command-line flags

2007-05-05T00:51:33+00:00

- Removed debug related targets from all Makefiles.  Debug builds are now fully
  controlled by --enable-debug passed to configure
- Disable optimizations by default when configuring with --enable-debug
- Added --enable-profiling for building profile builds.  This has problems with
  optimizations currently, but that'll get taken care of over time.
- Initialize ASFLAGS/CFLAGS/CPPFLAGS/OBJCFLAGS/LDFLAGS early so that autoconf
  defaults don't come into play.
- Added some additional commentary to configure.ac

Mac OS X Universal Binary support

Replace obsolete macros (processing done by autoupdate).

2007-03-29T18:23:36+00:00

Some tests were rearranged (AC_TRY_LINK moved out of AC_TRY_RUN
cross-compilation case, with arrangements to maintain the semantics) to
avoid autoupdate errors.
Factored out common (duplicate) code in aa.m4.
Tested with autoconf 2.61; needs testing with 2.60.

CVS patchset: 8598
CVS date: 2007/02/18 08:46:43

Fix strict aliasing rules breakages where possible, enable -fno-strict-aliasing where the breakage is unresolvable, and not enable it globally (decreases performances).

ffmpeg automagic improvements:

2006-03-28T14:27:48+00:00

  - support FreeBSD port of external ffmpeg (but there is too old version
    now anyway)
  - differs postproc and avcodec, use both in Makefile (fixes bug seen in
    Gentoo)
little fix in optimize automagic:
  - properly use '$' in automagic macros
