These minor changes allow getprocaddress to return an error code
in the case of test failure. This allows the program to be integrated
into the piglit test suite.
- Allow the getprocaddress test to test extensions not supported by
Mesa. The original getprocaddress.py script only included OpenGL
extension functions that were in Mesa dispatch tables. Now all
known extension functions (as detailed in gl_API.xml) are included.
As the test does not link against any extension function symbols
(i.e. it uses glXGetProcAddress() for all extension functions),
it still compiles and links against Mesa; but now the same
binary can be used to test extensions not yet supported by Mesa.
- Extend the list of tested extension functions. The last revision
of this test exercised 16 extension functions; this revision adds
support for 95 more.
