This patch removes two Clang warnings in GLU:
The first one seems to be an actual bug in mapdesc.cc: Clang complains
that sizeof(dest) will return the size of REAL*[MAXCOORDS], instead of
the intended REAL[MAXCOORDS][MAXCOORDS]. The second one is just
cosmetic because Clang doesn't like extra parentheses.

Commit 0c005bd7 intended to make ir_loop_jump::mode public, but also
accidentally added a new pointer to the enclosing loop. Furthermore, it
tried to initialize the new field by adding "this->loop = loop;" to the
constructor, but since there is no loop parameter, this only initialized
the field to itself---so it will likely be a garbage pointer.
A lot of code, such as lower_jumps, allocates new loop jumps without
setting this field appropriately, so any uses would probably just crash.
Thankfully, there were none, so we can just delete the field.

This replaces the _mesa_is_legal_format_and_type() function.
According to the spec, some invalid format/type combinations to
glDrawPixels, ReadPixels and glTexImage should generate
GL_INVALID_ENUM but others should generate GL_INVALID_OPERATION.
With the old function we didn't make that distinction and generated
GL_INVALID_ENUM errors instead of GL_INVALID_OPERATION. The new
function returns one of those errors or GL_NO_ERROR.
This will also let us remove some redundant format/type checks in
follow-on commit.

_mesa_error_check_format_and_type() per Ian.

The idea here is to rewrite comparisons like 2 >= x with x <= 2; we want
to simply exchange arguments, not negate the condition. If equality was
part of the original comparison, it should remain part of the swapped
version.
This is the true cause of bug #50298. It didn't manifest itself on
Sandybridge because we embed the conditional modifier in the IF
instruction rather than emitting a CMP. All other platforms use CMP.
It also didn't manifest itself on the master branch because commit
be5f27a84d ("glsl: Refine the loop instruction counting.") papered over
the problem.

This patch removes ARB_framebuffer_object from the GLES1 and GLES2
extension lists in intel_extensions_es.c.
Fixes a crash in the Android browser on Ice Cream Sandwich.
The Android browser crashed because it did the following, which is legal
in GLES2 but not in ARB_framebuffer_object.
glGenFramebuffers(1, &fb);
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// render render render...
glDeleteFramebuffers(1, &fb);
// go do other stuff...
glBindFramebuffer(GL_FRAMEBUFFER, fb);
// This bind unexpectedly failed, and the app panics.
The semantics of glBindFramebuffer specified by ARB_framebuffer_object (a
desktop GL extension) and GLES2 specs are incompatible. The ideal solution
to fix this is to create separate API entry points for glBindFramebuffer,
one for GL and the other for GLES2. But, until that work is complete,
disabling ARB_framebuffer_object in GLES2 contexts safely fixes the problem.
Likewise, the semantics of glBindFramebuffer in ARB_framebuffer_object and
of glBindFramebufferOES in OES_framebuffer_object (a GLES1 extension) are
incompatible. Even though the functions have different names, the semantic
difference still results in a bug because both API calls are implemented
by a single function, _mesa_BindFramebufferEXT, which handles the semantic
difference incorrectly. Again, disabling ARB_framebuffer_object in GLES1
contexts safely fixes this problem.
According to the ARB_framebuffer_object spec, the extension is an
amalgamation of
EXT_framebuffer_object
EXT_framebuffer_blit
EXT_packed_depth_stencil
EXT_framebuffer_multisample
By disabling this extension, however, no functionality is removed from
GLES1 and GLES2 contexts because 1) the first three extensions are
explicitly enabled in Intel's ES extension lists and 2) no functionality
of the last extension is exposed in an ES context.

It seems silly that GL lets you allocate these given that they're

actually go looking to see if the getters on 0-width/height
depth/stencil renderbuffers return good values. By failing out here,
they all got smashed to 0, which turned out to be correct for all the
getters they tested except for GL_RENDERBUFFER_INTERNAL_FORMAT. Now,
by succeeding but not making a miptree, that one also returns the

When glTexImage or glCopyTexImage is called with internalFormat being a

the texture target is compatible with the format. None of the texture
compression formats we support so far work with GL_TEXTURE_1D, for example.
