From 5aa6dc329b983b95071700c3af9353e3b35454d9 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Thu, 27 Jan 2005 01:08:48 +0000 Subject: [PATCH] The 'mode' setting of a function within an 'enum' element is now used. 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. --- src/mesa/glapi/Makefile | 4 +- src/mesa/glapi/glX_XML.py | 26 ++++++-- src/mesa/glapi/glX_proto_size.py | 137 +++++++++++++++++++++++++++++++-------- 3 files changed, 131 insertions(+), 36 deletions(-) diff --git a/src/mesa/glapi/Makefile b/src/mesa/glapi/Makefile index 35d8951..ba89550 100644 --- a/src/mesa/glapi/Makefile +++ b/src/mesa/glapi/Makefile @@ -57,10 +57,10 @@ glapitable.h: $(COMMON) gl_table.py $(PYTHON2) $(PYTHON_FLAGS) glX_proto_send.py -m init_c > ../../glx/x11/indirect_init.c ../../glx/x11/indirect_size.h: $(COMMON_GLX) glX_proto_size.py - $(PYTHON2) $(PYTHON_FLAGS) glX_proto_size.py -m size_h > ../../glx/x11/indirect_size.h + $(PYTHON2) $(PYTHON_FLAGS) glX_proto_size.py -m size_h --only-set > ../../glx/x11/indirect_size.h ../../glx/x11/indirect_size.c: $(COMMON_GLX) glX_proto_size.py - $(PYTHON2) $(PYTHON_FLAGS) glX_proto_size.py -m size_c > ../../glx/x11/indirect_size.c + $(PYTHON2) $(PYTHON_FLAGS) glX_proto_size.py -m size_c --only-set > ../../glx/x11/indirect_size.c clean: rm -f *~ *.pyo diff --git a/src/mesa/glapi/glX_XML.py b/src/mesa/glapi/glX_XML.py index 9d8fe00..dcfb015 100644 --- a/src/mesa/glapi/glX_XML.py +++ b/src/mesa/glapi/glX_XML.py @@ -83,7 +83,9 @@ class glXItemFactory(gl_XML.glItemFactory): class glXEnumFunction: def __init__(self, name): self.name = name - + self.mode = 0 + self.sig = None + # "enums" is a set of lists.
