Previously, we used the mesa_name XML attribute to make the code generation scripts aware of any instances where the Mesa implementation of a function had a different function name suffix than the primary name in the XML. Now that all of the Mesa implementation functions have been renamed to match the XML, this attribute is no longer necessary. Acked-by: Brian Paul <brianp@vmware.com>

<!--
|
|
The various attributes for param and glx have the meanings listed below.
|
|
When adding new functions, please annote them correctly. In most cases this
|
|
will just mean adding a '<glx ignore="true"/>' tag.
|
|
|
|
param:
|
|
name - name of the parameter
|
|
type - fully qualified type (e.g., with "const", etc.)
|
|
client_only - boolean flag set on parameters which are interpreted only
|
|
by the client and are not present in the protocol encoding (e.g.,
|
|
the stride parameters to Map1f, etc.)
|
|
count - for counted arrays (e.g., the 'lists' parameter to glCallLists),
|
|
the parameter or literal that represents the count. For functions
|
|
like glVertex3fv it will be a litteral, for others it will be one of
|
|
the parameters.
|
|
counter - this parameter is a counter that will be referenced by the
|
|
'count' attribute in another parameter.
|
|
count_scale - literal value scale factor for the 'count' attribute.
|
|
See ProgramParameters4dvNV for an example.
|
|
output - this parameter is used to store the output of the function.
|
|
variable_param - name of parameter used to determine the number of
|
|
elements referenced by this parameter. This should be the name of a
|
|
single enum parameter. Most of the gl*Parameter[if]v functions use
|
|
this. Additionally, the enums that can be passed should be properly
|
|
annotated.
|
|
img_width / img_height / img_depth / img_extent - name of parameters
|
|
(or hardcoded integer) used for the dimensions of pixel data.
|
|
img_xoff / img_yoff / img_zoff / img_woff - name of parameters used
|
|
for x, y, z, and w offsets of pixel data.
|
|
img_format - name of parameter used as the pixel data format.
|
|
img_type - name of parameter used as the pixel data type.
|
|
img_target - name of parameter used as a texture target. Non-texture
|
|
pixel data should hardcode 0.
|
|
img_send_null - boolean flag to determine if blank pixel data should
|
|
be sent when a NULL pointer is passed. This is only used by
|
|
TexImage1D and TexImage2D.
|
|
img_null_flag - boolean flag to determine if an extra flag is used to
|
|
determine if a NULL pixel pointer was passed. This is used by
|
|
TexSubImage1D, TexSubImage2D, TexImage3D and others.
|
|
img_pad_dimensions - boolean flag to determine if dimension data and
|
|
offset data should be padded to the next even number of dimensions.
|
|
For example, this will insert an empty "height" field after the
|
|
"width" field in the protocol for TexImage1D.
|
|
|
|
glx:
|
|
rop - Opcode value for "render" commands
|
|
sop - Opcode value for "single" commands
|
|
vendorpriv - Opcode value for vendor private (or vendor private with
|
|
reply) commands
|
|
large - set to "true" of the render command can use RenderLarge protocol.
|
|
doubles_in_order - older commands always put GLdouble data at the
|
|
start of the render packet. Newer commands (e.g.,
|
|
ProgramEnvParameter4dvARB) put the in the order that they appear
|
|
in the parameter list.
|
|
always_array - some single commands take reply data as an array or as
|
|
return value data (e.g., glGetLightfv). Other single commands take
|
|
reply data only as an array (e.g., glGetClipPlane).
|
|
handcode - some functions are just too complicated to generate
|
|
(e.g., glSeperableFilter2D) or operate only on client-side data
|
|
(e.g., glVertexPointer) and must be handcoded.
|
|
ignore - some functions have an entry in the dispatch table, but aren't
|
|
suitable for protocol implementation (e.g., glLockArraysEXT). This
|
|
also applies to functions that don't have any GLX protocol specified
|
|
(e.g., glGetFogFuncSGIS).
