When we start compiling a shader, first free the existing gl_program.
This (mostly) fixes the piglit glsl-reload-source test.
Without this change, we were actually appending the new GPU code
onto the previous program.

This prevents the mystery blank window if, for example, glxgears is
resized larger than 2048 wide on 915. Since the Intel drivers in Mesa
7.6 lack GTT mapped fallbacks, the performance is a slideshow at
best. On Mesa 7.7 and later the performance is much better.

If a register was only being used as a destination (as will happen when
generated condition-codes) we missed its use. So we'd errantly return
a register index that was really in-use, not free.
Fixes bug 25579.

For some cases, _mesa_GetIntegerv reads up to params[15].
|
|
|
|
|
|
_mesa_TexGend calls _mesa_TexGenfv, which uses the params argument
as an array.
|
|
_mesa_Lighti calls _mesa_Lightiv, which uses the params argument
as an array.
|
|
|
|
_mesa_PointParameteri calls _mesa_PointParameterfv, which uses the
params argument as an array.
|
|
_mesa_PointParameterf calls _mesa_PointParameterfv, which uses the
params argument as an array.
|
|
_mesa_LightModelf calls _mesa_LightModelfv, which uses the
params argument as an array.
|
|
|
|
This fixes invalid array indexing when baseLevel == MAX_TEXTURE_LEVELS.
