2005-07-18Wrap every place that accesses a dispatch table with a macro. A new script-Ian Romanick
generated file, called src/mesa/glapi/dispatch.h, is added. This file contains three macros for each API function. It contains a GET, a SET, and a CALL. Each of the macros take a pointer to the context and a pointer to the dispatch table. In several threads on mesa3d-dev we discussed replacing _glapi_add_entrypoint with a new function called _glapi_add_dispatch. For this discussion, the important difference between the two is that the caller of _glapi_add_dispatch does *not* know what the dispatch offset will be at compile time. Because of this callers need to track the dispatch offset returned by _glapi_add_dispatch. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2 The downside is that driver code then has to access the dispatch table two different ways. It accesses it using structure tags (e.g., exec->Begin) for functions with fixed offsets and via a remap table (e.g., exec[ remap->NewExtensionFunction ]) for functions without fixed offsets. Yuck! Using the macros allows both types of functions to be accessed identically. If a driver needs to set a pointer for Begin, it does 'SET_Begin(ctx, exec, my_begin_function)'. If it needs to set a pointer for NewExtensionFunction, it does 'SET_NewExtensionFunction(ctx, exec, my_NewExtensionFunction_function)'. Furthermore, if at some point in the future a static offset is assigned for NewExtensionFunction, only the macros need to change (instead of every single place that accesses a table for that function). This code differs slightly from the originally posted patches in that the CALL, GET, and SET marcos no longer take a context pointer as a parameter. Brian Paul had suggested that the remap table could be stored as a global since it would be set at CreateScreen time and would be constant for all contexts. This change reflects that feedback. http://marc.theaimsgroup.com/?t=112087194700001&r=1&w=2
2005-07-01Move the PYTHON2 and PYTHON_FLAGS assignments to configs/current, andBrian Paul
include $(TOP)/configs/current in glapi/Makefile so those vars can be easily overridden by any system config, if needed.
2005-06-30Replace add_newer_entrypoints (src/mesa/main/context.c) withIan Romanick
device-specific code. A new Python script (src/mesa/glapi/extension_helper.py) generates a list of all entry-points for all known extensions. Each driver the selects only the extensions that it needs and enables the via either driInitExtensions or driInitSingleExtension. This code has been compile-tested on a drivers, but has only been run-tested on mga and i915 (on i830 hardware). These changes were discussed at length on the mesa3d-dev mailing list. http://marc.theaimsgroup.com/?t=111947074700001&r=1&w=2
2005-06-21Mammoth update to the Python code generator scripts that live inIan Romanick
src/mesa/glapi. Basically, the scripts that did simple things (like gl_offsets.py) were simple, and the scripts that did more complicated things (like glX_proto_send.py) were getting progressively more and more out of control. So, I re-write the foundation classes on which everything is based. One problem with the existing code is that the division between the GL API database representation and the way the output code is generated was either blury or nonexistant. The new code somewhat follows the Model-View-Controller pattern, minus the Controller. There is a distinct set of classes that model the API data, and there is a distinct set of classes that generate code from that data. One big change is in the class that represents GL functions (was glFunction, is now gl_function). There used to be an instance of this calls for each function and for each alias to that function. For example, there was an instance for PointParameterivSGIS, PointParameterivEXT, PointParameterivARB, and PointParameteriv. In the new code, there is one instance. Each instance has a list of entrypoint names for the function. In the next revision, this will allow a couple useful things. The script will be able to verify that the parameters, return type, and GLX protocol for a function and all it's aliases match. It will also allow aliases to be represented in the XML more compactly. Instead of repeating all the information, an alias can be listed as: <function name="PointParameterivARB" alias="PointParameterivEXT"/> Because the data representation was changed, the order that the alias functions are processed by the scripts also changed. This accounts for at least 2,700 of the ~3,600 lines of diffs in the generated code. Most of the remaining ~900 lines of diffs are the result of bugs *fixed* by the new scripts. The old scripts also generated code with some bugs in it. These bugs were discovered while the new code was being written. These changes were discussed on the mesa3d-dev mailing list back at the end of May: http://marc.theaimsgroup.com/?t=111714569000004&r=1&w=2 Xorg bug: 3197, 3208
2005-02-22generate enums.c file (Zack Rusin)Brian Paul
2005-01-28Refactor the code to emit multiple-inclusion protection toIan Romanick
FilterGLAPISpecBase. Since the size_h mode of glX_proto_size.py will be used to generate multiple header files, add an option to specify the define that is used for multiple-inclusion protection. The changes to the header files in this commit are just a side-effect of the changes to the Python scripts.
2005-01-27The 'mode' setting of a function within an 'enum' element is now used.Ian Romanick
Parameters to glX_proto_size.py are now used to determine whether to emit either get-type function, set-type functions, or both. When only get-type functions are emitted, they can optionally alias set-type functions. This would be useful if, for example, the two types were in different source files. The real work to implement this is in SizeStubFunctionIterator class. All of the logic for which functions to iterate and in which order is implemented there.
