Matt Turner b21ad12485 mesa: Have configure define NDEBUG, not mtypes.h.
mtypes.h had been defining NDEBUG (used by assert) if DEBUG was not
defined. Confusing and bizarre that you don't get NDEBUG if you don't
include mtypes.h.

... which is just what happened in commit bef38f62e.

Let's let configure define this for us if not using --enable-debug.

Emil Velikov dd7b6670a2 auxiliary/vl: Build vl_winsys_dri.c only when needed.
With commit c39dbfdd0f7(auxiliary/vl: bring back the VL code for the dri
targets) we did not fully consider users of dri-swrast alone. Thus we
ended up trying to compile the dri2 specific code on platform which lack
it - Cygwin for example.

Emil Velikov c39dbfdd0f auxiliary/vl: bring back the VL code for the dri targets
With commit c642e87d9f4(auxiliary/vl: rework the build of the VL code)
we split out the VL code into a separate static library that was meant
to be used by the VL targets alone - va, vdpau, xvmc.

The commit failed to consider the way we handle vdpau-gl interop and
broke it. Bring back the functionality by keeping the vl <> vl_stub
separation as requrested by Christian.

v2: Update the omx target as well. Update mesa-stable email address.

Emil Velikov 153539bd9d configure: rework wayland_scanner handling(fix make distcheck)
Currently having the wayland-scanner is optional, which causes problems
when autotools parses through the makefiles, and tries to generate all
the BUILT_SOURCES.

As the config option --with-egl-platform=wayland is not the default, we
won't end up setting the WAYLAND_SCANNER variable, which in turn will
cause some files to not get generated.

There has been a wayland-scanner package as of wayland 1.2 which
provides a variable for the scanner binary, so let's use that one and
fall back to manually searching via AC_PATH_PROG when needed.

Carl Worth 59216f53ec configure: Add machinery for --enable-shader-cache (and --disable-shader-cache)
We don't actually have the code for the shader cache just yet, but
this configure machinery puts everything in place so that the shader
cache can be optionally compiled in.

Specifically, if the user passes no option (neither
--disable-shader-cache, nor --enable-shader-cache), then this feature
will be automatically detected based on the presence of a usable SHA-1
library. If no suitable library can be found, then the shader cache
will be automatically disabled, (and reported in the final output from
configure).

The user can force the shader-cache feature to not be compiled, (even
if a SHA-1 library is detected), by passing
--disable-shader-cache. This will prevent the compiled Mesa libraries
from depending on any library for SHA-1 implementation.

Finally, the user can also force the shader cache on with
--enable-shader-cache. This will cause configure to trigger a fatal
error if no sutiable SHA-1 implementation can be found for the
shader-cache feature.

Bug fix by José Fonseca <jfonseca@vmware.com>: Fix to put conditional
assignment in Makefile.am, not Makefile.sources to avoid breaking
scons build.

Note: As recommended by José, with this commit the scons build will
not compile any of the SHA-1-using code. This is waiting for someone
to write SConstruct detection of the available SHA-1 libraries, (and
set the appropriate HAVE_SHA1_* variables).

Carl Worth 670826b431 configure: Add copyright and license block to configure.ac
Prior to copying in code from the xserver configure.ac file, it makes
sense to have the license of this file clearly marked, (to show that
it's licensed identically to the configure.ac file from the xserver
repository).

And since the text of the license refers to "the above copyright
notice" it also makes sense to have an actual copyright attribution in
place.

I generated this list of names by looking at the output of:

	git shortlog -n --format=%aD -- configure.ac

(and arbitrarily stopping for contributors with fewer than 15
commits). Then for each name, I looked for existing Copyright
attributions in the mesa source tree with the same name, (and using
"Intel Corporation" as the copyright holder where I knew that was
appropriate).

Emil Velikov 1a6ae84041 configure.ac: roll up a program for the sse4.1 check
So when checking/building sse code we have three possibilities:
 1 Old compiler, throws an error when using -msse*
 2 New compiler, user disables sse* (-mno-sse*)
 3 New compiler, user doesn't disable sse

The original code, added code for #1 but not #2. Later on we patched
around the lack of handling #2 by wrapping the code in __SSE4_1__.
Yet it lead to a missing/undefined symbol in case of #1 or #2, which
might cause an issue for #2 when using the i965 driver.

A bit later we "fixed" the undefined symbol by using #1, rather than
updating it to handle #2. With this commit we set things straight :)

To top it all up, conventions state that in case of conflicting
(-enable-foo -disable-foo) options, the latter one takes precedence.
Thus we need to make sure to prepend -msse4.1 to CFLAGS in our test.

v2: Clean the #includes. Suggested by Ilia, Matt & Siavash.

Matt Turner 28e84c93bb configure.ac: Drop gallium directory tracking.
Was only tracked to be printed at the end of configure, but configure
quits if it can't build something we requested, rather than silently
dropping it, so printing these directories has little use.

Matt Turner 691bd9b9df configure.ac: Use autoconf macro for GNU make. 2014-09-25 13:57:28 -07:00
Matt Turner e4be17fd04 ralloc: Mark ralloc functions with gcc's malloc attribute.
Cuts a few hundred bytes from the DRI drivers, so it must give gcc some
extra information.
