/*
DEV_NOTE: As of the inclusion of this file, there are no areas of Omni that
utilize architecture specific code and as a rule-of-thumb for Omni, we try
to avoid architecture specific code to be as cross-system compatible as
possible. However, that does not preclude one from using arch-specific code
if it makes sense to enable certain optimizations in the source.
Please note that just because a specific macro is defined below, does not
mean the library has been tested to work in that environment. OMNI_ARCH_PPC
will be defined, for instance, if the __powerpc macro is defined (usually by
the compiler), but this does not mean we have been able to test/build the
library in a direct (or even emulated) PowerPPC environment.
That being said, the purpose of this file is to give helper macros for
possible architecture compilation detection, keyword being possible. Should
a need ever arise to force the Omni library to build for a separate architecture
(e.g. building an ARM version on an Intel processor), one can define the
OMNI_ARCH_IGNORE preprocessor define and specify which ever architecture
via one of the below defines.
DEV_NOTE: These macro's do not determine the bit-width of the architecture,
instead these are merely guesses based on common compilation defines to
determine what architecture the library is being compiled for.
