When compiled with the more aggressive compiler warnings such as
-Wshadow and -Wempty-body the libtess code gives a lot more
warnings. This fixes the following issues:
* The 'Swap' macro tries to combine multiple statements into one and
then consume the trailing semicolon by using if(1){/*...*/}else.
This gives warnings because the else part ends up with an empty
statement. It also seems a bit dangerous because if the semicolon
were missed then it would still be valid syntax but it would just
ignore the following statement. This patch replaces it with the more
common idiom do { /*...*/ } while(0).
* 'free' was being used as a local variable name but this shadows the
global function. This has been renamed to 'free_handle'
* TRUE and FALSE were being unconditionally defined. Although this
isn't currently a problem it seems better to guard them with #ifndef
because it's quite common for them to be defined in other headers.

Windows unloads DLLs before atexit. Make _eglUnloadDrivers no-op on
Windows for now.
|

The configs should be FREE()ed, not free()ed. We cannot rely on
_eglCleanupDisplay here.
|

Dynamic arrays will be used to store configs and screens of a display.

A vg_shader is destroyed with FREE.

changes.
It's a rare condition, but it may happen if all primitives are
clipped/culled.
For now we just do a no-op rasterization, but we could bypass it.
|
|
The previous rendering may have secondary effects on the zsbuf.
Fixes the missing tiles on gearbox.

The target supports OpenVG on Windows with software rasterizer. The
egl_g3d_loader defined by the target supports arbitrary client APIs and
window systems. It is the SConscript that limits the support to OpenVG
and GDI.
This commit also fixes a typo in gdi backend.

Patch from Brad Smith <brad@comstyle.com>
The attached patch allows the GL_OES_query_matrix function to use the
systems fpclassify() for OpenBSD and NetBSD.

geometry shaders emit/end functions don't take any arguments

This flush happens when changing the tiling flags, and it should really be
done in the context.
I hope this fixes FDO bug #28630.

Check for null pointers and return early, etc.

This undoes part of commit 8be645d53a0d5d0ca50e4e9597043225e2231b6d
and fixes fd.o bug 28822 as well as other regressions.
The 'draw' module may issue additional state-change commands while
we're inside the draw_arrays/elements() call so it's important to
check for updated state at this point.

Also fix pipe_radeon.so not building

Otherwise gcc will warn about unusued functions.

This change makes st/egl build a single egl_gallium.so and multiple
st_<API>.so and pipe_<HW>.so. When a display is initialized, the
corresponding pipe driver will be loaded. When a context is created,
the corresponding state tracker will be loaded.
Unlike DRI drivers, no ABI compatibility is maintained. egl_gallium,
pipe drivers and state trackers should always be distributed as a single
package. As such, there is only a single src/gallium/targets/egl/ that
builds everything for the package.
|
|
Several changes are made. libegl.a no longer defines _eglMain. It
defines functions to create and destroy a _EGLDriver instead. The
creation function is called by the targets. It takes an egl_g3d_loader
as its argument. The loader is defined by the targets and is in charge
of creating st_api and pipe_screen. This allows us to move the module
loading code to targets. Lastly, the modules are now loaded as the
respective contexts are created.
|
|
Merge all targets into targets/egl/. The target produces
egl_gallium_<HW>.so for each pipe driver and st_<API>.so for each client
APIs. This enables us to further merge egl_gallium_<HW>.so into
egl_gallium.so later.
|
|
Merge multiple egl_<platform>_<pipe>.so into a single
egl_gallium_<pipe>.so. The environment variable EGL_PLATFORM is now
used to modify the return value of _eglGetNativePlatform.
|
|
Move native_get_name, native_create_probe, native_get_probe_result, and
native_create_display into struct native_platform, and add
native_get_platform to get a handle to the struct.
|
|
This allows api_OpenGL.so to support OpenGL ES.
|
|
Add st_gl_api_create_es1 and st_gl_api_create_es2 to create OpeGL ES 1.1
and OpenGL ES 2.0 contexts respectively.
|
|
The callback is used by st/vega to check if a visual specifies the
depth/stencil format. It forces st/vega to be loaded by st/egl to
perform the check. As noted in EGL spec, the depth/stencil format of a
visual should not affect OpenVG. It should be better to ignore the
field and always allocate the depth/stencil texture.

laying down the foundation for everything and implementing most of the
stuff.
linking, gl_VerticesIn and multidimensional inputs are left.

Ooops. This should possibly fix some bugs...

The cpu_access is redundant in a software rasterizer.

lp_setup_bind_framebuffer().
We were starting a scene whenever lp_setup_get_vertex_info() was called by
the draw module. So when when all primitives were culled/clipped, not only
did we create a new scene for nothing, but we end up using the old scene
with the old framebuffer state instead of a new one.
Fix consists in:
- don't call lp_setup_update_state() in lp_setup_get_vertex_info() -- no
longer necessary
- always setting the scene state before binning a command -- query
commands were bypassing it
- assert no old scene is reused in lp_setup_bind_framebuffer()
