was added in commit d6863acb, we renamed variables appearing in
interface blocks so that their name included the array size.  For
example, in a block like this:

out foo {
   float bar
} baz[3];

The variable "bar" would get renamed to "bar[3]".

This is unnecessary, and leads to problems in supporting geometry
shaders, since geometry shaders require vertex shader outputs which
are non-arrays to be linked up to geometry shader inputs which are
arrays.

This patch makes the behaviour of interface block arrays the same as

11 years agomesa: Dispatch ARB_framebuffer_object and EXT_framebuffer_object differently
Tomasz Lis [Tue, 16 Jul 2013 18:57:26 +0000 (20:57 +0200)]
mesa: Dispatch ARB_framebuffer_object and EXT_framebuffer_object differently

Almost all of the functions between the ARB and the EXT share the same
GLX protocol because the functionality is, essentially, identical.
However, there are some differences between the extensions:

- In the ARB extension, names must come from glGenBuffers.

- In the ARB extension, framebuffer objects are not shared (but they are
  in the EXT).

For these reasons, glBindFramebuffer and glBindRenderbuffer have
different GLX protocol opcodes than their EXT counterparts.  Currently
these functions alias each other in the dispatch table.  This makes it
impossible to be truly spec conformant.

This patch enables fixing the conformance issue by splitting
glBindFramebuffer / glBindFramebufferEXT and glBindRenderbuffer /
glBindRenderbufferEXT into separate dispatch table entries.

Patches will be available shortly to:

- Fix the conformance issue.

- Stop advertising the EXT in OpenGL 3.1 (or core profiles).

HOWEVER, this does represent a compatibility break between the loader
(libGL or the Xserver GLX module) and the driver.  Mesa drivers compiled
without this change will request a single dispatch table entry for
glBindFramebuffer and glBindFramebufferEXT.  Since the updated loader
has different entries for each, the request will fail, and the driver
will die in a fire.

Drivers built with the change should continue to load fine on loaders
without the change.  In this case, the driver will separately ask for
entries for glBindFramebuffer and glBindFramebufferEXT, and the loader
will tell it the same location.  Since the loader in the server's GLX
module is not (yet) updated, this should not be a problem.  We also do
not advertise the ARB extension from the server, so, again, this should
not be a problem for the server.

HOWEVER, this means that DRI1 drivers (remember mga_dri.so?) will no
longer load with libGL build hereafter.  That means this patch will need
to be back ported to the 8.0 branch.

v2 (idr): Added missing GLX protocol opcodes for the EXT functions and
corrected the opcodes for the ARB functions.  Updated GLX indirect_api
unit test and dispatch sanity unit test.

Currently, we store precision in ast_type_specifier, rather than
ast_type_qualifier.  This works because precision is the last qualifier,
and immediately adjacent to the type.

Default precision statements (such as "precision highp float") are
represented as ast_type_specifier objects, with a boolean to indicate
that it's a default precision statement rather than an ordinary type.

ast_type_specifier::precision will be moving to ast_type_qualifier soon,
in order to support arbitrary qualifier ordering.  However, we still
need to store a "this is a precision statement" flag /and/ the default
precision in ast_type_specifier.

This patch changes the boolean into a new field, default_precision.
If default_precision != ast_precision_none, it's a precision statement
with the specified precision.  Otherwise, it's an ordinary type.
