libasan is never linked to shared objects (which doesn't go well with
-z,defs). It must either be linked to the main executable, or (more
practically for OpenGL drivers) be pre-loaded via LD_PRELOAD.
Otherwise works.
I didn't find anything with llvmpipe. I suspect the fact that the
JIT compiled code isn't instrumented means there are lots of errors it
can't catch.
But for non-JIT drivers, the Address/Leak Sanitizers seem like a faster
alternative to Valgrind.
Usage (Ubuntu 15.10):
scons asan=1 libgl-xlib
export LD_LIBRARY_PATH=$PWD/build/linux-x86_64-debug/gallium/targets/libgl-xlib
LD_PRELOAD=libasan.so.2 any-opengl-application

For Clang static code analyzer, the scan-build script will produce more
comprehensive output. Nevertheless you can invoke it as
CC=clang CXX=clang++ scons analyze=1
For MSVC this is the best way to use its static code analysis. Simply
invoke as
scons analyze=1

scons: Fix SCons build infrastructure for FreeBSD.
This patch gets the FreeBSD SCons build working again. The build still
fails though.

scons: Reduce all Cygwin platform names to 'cygwin'.
platform.system in SCons on Cygwin includes the OS version number.
Windows XP - CYGWIN_NT-5.1
Windows Vista - CYGWIN_NT-6.0
Windows 7 - CYGWIN_NT-6.1
Reduce all Cygwin platform variants to just 'cygwin' so anything
downstream can simply use 'cygwin' instead of the different full
platform names.
GLES can be enabled by running scons with
$ scons gles=yes
When gles=yes is given, the build is changed in three ways. First,
libmesa.a will be built with FEATURE_ES1 and FEATURE_ES2. This makes
DRI drivers and libEGL support and advertise GLES support. Second, GLES
libraries will be created. They are libGLESv1_CM, libGLESv2, and
libglapi. Last, libGL or opengl32 will link to libglapi. This change
is required as _glapi_* will be declared as __declspec(dllimport) in
libmesa.a on windows. libmesa.a expects those symbols to be defined in
another DLL. Due to this change to GL, GLES support is marked
experimental.
Note that GLES requires libxml2-python to generate some of its sources.
Use scons target and dependency system instead of ad-hoc options.
Now is simply a matter of naming what to build. For example:
scons libgl-xlib
scons libgl-gdi
scons graw-progs
scons llvmpipe
and so on. And there is also the possibility of scepcified subdirs, e.g.
scons src/gallium/drivers
If nothing is specified then everything will be build.
There might be some rough corners over the next days. Please bare with me.
The test for env['platform'] caused an exception since 'env' is not
defined at that point. Instead, determine the target platform by
scanning sys.argv[].
I've been back and forth on this, but I believe it's worth to have debug
by default.
Most humans (developers, testers) will want to use the debug version by
default. Many build bots want release but they are bots, and humans >
bots, so I don't care that much.
This is part of my initiative of minimizing the scons option mess many
complain about.
Now that draw depends on llvm it is very difficult to correctly handle
broken llvm installations. Either the user requests LLVM and it needs to
supply a working installation. Or it doesn't, and it gets no LLVM
accelerate pipe drivers.
