CROSS-PLATFORM PORTABILITY GUIDELINES FOR GALLIUM3D
= General Considerations =
The state tracker and winsys driver support a rather limited number of
platforms. However, the pipe drivers are meant to run in a wide number of
platforms. Hence the pipe drivers, the auxiliary modules, and all public
headers in general, should stricly follow these guidelines to ensure
= Compiler Support =
* Include the p_compiler.h.
* Don't use the 'inline' keyword, use the INLINE macro in p_compiler.h instead.
* Cast explicitly when converting to integer types of smaller sizes.
* Cast explicitly when converting between float, double and integral types.
* Don't use named struct initializers.
* Don't use variable number of macro arguments. Use static inline functions
instead.
= Standard Library =
* Avoid including standard library headers. Most standard library functions are
not available in Windows Kernel Mode. Use the appropriate p_*.h include.
== Memory Allocation ==
* Use MALLOC, CALLOC, FREE instead of the malloc, calloc, free functions.
* Use align_pointer() function defined in p_util.h for aligning pointers in a
portable way.
== Debugging ==
