Need to execute the for loop's increment code before we continue.
Add a slang_assemble_ctx::CurLoopOper field to keep track of the containing
loop and avoid the "cont if true" path in this situation.
Plus, assorted clean-ups.

The previous test failed for nested loops.

Just search the AST in _slang_can_unroll_for_loop().
|
|
We should just check if the loop contains a continue/break in the
_slang_can_unroll_for_loop() test function...
This reverts commit 989856bde47d699d7e18798df4013fbf962e1d4b.

This is the start of a glsl-continue-return feature branch to support
a GLSL code generator option for 'continue' and 'return' statements.
Some targets don't support CONT or RET statements so we'll need to
try to generate code that does not use them...

Also works with MinGW, as long as the path to the DirectX SDK top
directory is set in the DXSDK_DIR environment variable.

We were failing to deal with:
- vsnprintf returns negative value on error.
- vsnprintf returns the number of chars that *would* have been
written on truncation.

Theoretical bugfix only - no known case where this might happen.

|
Fixes assertion failure with conform.

The reshape() function was called when there was no GLX context so
the viewport/modelview/projection setup wasn't doing anything. Move
the call to reshape() into draw().
Also, remove -stereo, -fullscreen options and do some general clean-up.

glsl compiler will not generate OPCODE_SWZ, and as a first step it would
be translated away to a MOV anyway (why?), but later internally this opcode is
generated (for EXT_texture_swizzling).

We currently don't have support for SGI_swap_control for direct
contexts with DRI2, so disable reporting the extension. Reporting
the extension, and then having glXSwapIntervalSGI() "succeed"
but do nothing can confuse applications.

Be clearer that this is the number of generic vertex program/shader
attributes, not counting the legacy attributes (pos, normal, color, etc).

Call the _mesa_set_enable() functions instead of driver functions, etc.
Also, add missing code for 1D/2D texture arrays.

If we're running a vertex program to emulated fixed-function, we still need
to treat vertex arrays/attributes as if we're in fixed-function mode.
This should probably be back-ported to Mesa 7.5 after a bit more testing.

When a GLSL sampler reads from an incomplete texture it should
return (0,0,0,1). Instead of jumping through hoops in all the drivers
to make this happen, just create/install a fallback texture with those
texel values.
Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some
GPU lockups when trying to sample from missing surfaces. If a binding
table entry is NULL, it seems that sampling sometimes works, but not
always (lockup).
Todo: create a fallback texture for each type of texture target?

The CALL_DrawArrays was leaking the clear's primitives into the display
list with GL_COMPILE_AND_EXECUTE. Use _mesa_DrawArrays instead, which
doesn't appear to leak. Fixes piglit dlist-clear test.

Fixes #22181. R200 requires this since DP4 is used in hw tnl mode.
R300 prefers it (should be faster due to no instruction dependencies), but
both methods should be correct (when sw tcl is used though, MUL/MAD might
be faster). Probably doesn't make much difference for R100 since vertex progs
are executed in software anyway, but let's just keep it the same there too.

The alpha value wasn't set at all before so we got unpredictable results.
Note that we don't currently obey GL_DEPTH_TEXTURE_MODE in the state
tracker. For now, we return the result in the default mode (r,r,r,1).

It is expected to loose precision here.

Using uintptr_t as intermediate type for pointer -> integer conversions is
easier to understand and does not cause any size mismatch warnings.
uintptr_t is part of C99, and we already provide a suitable replacement
definition for all platforms we care about.

Avoids warnings on 64bit builds.
Use regular unsigned since that's what gallium expects, but use a
typedef to facilitate possible changes in the future.

In multithreading stw_call_window_proc can be called by a thread other
than the thread where the context is bound.
|
|
Not only for cosmetic reasons, but also because we need to set the
SetWindowsHookEx hook for threads created before the DllMain is called
(threads for each we don't get the DLL_THREAD_ATTACH notification).

This was misspelt as glFramebufferTexturLayer (missing e), causing
conflicts with the correctly spelt version in glext.h and extfuncs.h.
