2006-10-11Fix bug #4681.Ian Romanick
glDeleteTextures and glDeleteTexturesEXT were erroneously listed as aliases of each other. For anything /except/ GLX protocol they are aliases. This set of changes allows functions that are functionally identical but have different GLX protocol to be listed as aliases. When building with GLX_INDIRECT_RENDERING set, different static functions are used. These functions determine whether the current context is direct rendering or not. If the context is direct rendering, the aliased function (e.g., glDeleteTextures in the case of glDeleteTexturesEXT) is called. If the context is not direct rendering, the correct GLX protocol is sent. For a deeper explanation of what is changed, please see: http://dri.freedesktop.org/wiki/PartiallyAliasedFunctions
2006-08-28Add two new gl_function methods. dispatch_name returns the name ofIan Romanick
the true static dispatch name (either the glFooBar name or the gl_dispatch_stub_XXX name). static_name returns the name of the static function for a specific alias of a GL function. Adding (and using) these two functions corrects some problems in the generated code related to functions with multiple aliases where some of the aliases have true static dispatch functions and some don't. I have verified that everything under progs, except xdemos/xdemo, correctly link. I did this by doing 'make linux-dri-x86-64 PROGRAM_DIRS="demos redbook samples xdemos tests"'.
2006-08-26Explicitly store the names for each function that should have a staticIan Romanick
entry point generated. This allows us to do things like generate a static entry point for glPointParameterfvARB but not for glPointParameterfvSGIS.
2006-08-22Add new attribute called static_dispatch to the <function> element. ThisIan Romanick
boolean attribute, which defaults to true, determines whether or not a static dispatch function is available in libGL for applications to link against. Ideally, any new functions that are not part of the ABI should not have directly accessable dispatch functions. This forces applications to use glXGetProcAddress to access these functions. By doing this we can gracefully remove functions from libGL without breaking the linkage of applications. Note that the static dispatch functions are still generated. However, they are given names like gl_dispatch_stub_820 and are marked with the "hidden" linker attribute. All extension functions added since the previous Mesa release (6.5) have been marked as 'static_dispatch="false"'.
2005-06-24Fix non-x86 specific builds. The changes from glTexImage3DEXT toIan Romanick
glTexImage3D that caused me so many problems during the re-development of the API scripts reared its ugly head again. This has been fixed by tracking the parameter string for each entry-point individually. This has the annoying side-effect that the names of the parameters in all aliases of a function must be the same or gl_apitemp.py will generate bad code. :( The changes in src/mesa/glapi/{gl_API.xml,glapitable.h} and src/glx/x11/* are caused by fixing the parameter names in various function aliases that didn't match.

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
2005-04-18Refactor a bunch of common code from the "leaf" scripts to a new functions,Ian Romanick
parse_GL_API, in gl_XML.py.
2005-04-18Convert all Python scripts to use XML namespaces.Ian Romanick
2005-01-25Add a glFunctionIterator class to iterate over the functions stored in aIan Romanick
higher-level API object. Use this type of object to implement the printFunctions method. Modify other functions that iterate over the list of functions to use this type of object.
2004-12-21Added some comments and fixed typeos. Slightly refactored the wayIan Romanick
function parameters are iterated. There are no changes in the generated code.
2004-11-27Use new _glapi_proc typedef instead of void * for function pointers.Brian Paul
Misc clean-ups in glapi.c
2004-10-02remove unused413 stuff, glDrawBuffersARB uses that slot nowBrian Paul
2004-09-09Another attempt at fixing name mangling and gl__unused413().Brian Paul
2004-08-25fix MGL namespace warning (patch 1014800)Brian Paul
2004-06-29First phase of TLS work. At this point SPARC assembly dispatch isIan Romanick
broken, but it will be fixed "shortly." This is pretty much the same as the patch I sent to the dri-devel list on 22-Jun-2004.
2004-05-19Added some in-code documentation. Modifed glParameter to be aIan Romanick
subclass of glItem.
2004-05-18New scripts for processing the XML version of APIspec. Mail is beingIan Romanick
sent to mesa3d-dev with a more detailed description.
