RHSK] * * mpstd.h does two main things: * 1. platform detection by looking at preprocessor symbols; * 2. setting variables (eg. MPS_PF_STRING, MPS_WORD_WIDTH). * * Sometimes the platform is *already* known by the buildsystem: * - the Global Graphics buildsystem always sets CONFIG_PF_*. * - the Ravenbrook buildsystem knows the platform and may (but * typically does not) set CONFIG_PF_*. * * Regardless of this, mpstd.h still attempts to detect the platform. * (This is intentional). However if both CONFIG_PF_* and * CONFIG_PF_STRING are set, then mpstd.h performs a third function: * 3. checking that the detected platform corresponds to that * specified by CONFIG_PF_*. * * Sometimes no MPS buildsystem is in use, so the platform *must* * be detected. For example, when client software #includes mps.h, * we want it to just work out of the box with whatever compiler is * being used. In other words we do not require the client to define * CONFIG_PF_*. * (This is the case that justifes mpstd.h doing platform detection * by looking at preprocessor symbols; otherwise we'd simply use * CONFIG_PF_*). * * mpstd.h fails if it cannot detect the platform (even if CONFIG_PF_* * is specified). This is intentional. mpstd.h does *not* allow * CONFIG_PF_* to override the platform as detected from preprocessor * symbols. This is intentional. * * References: * GG buildsys use of CONFIG_PF_*: * */ /* Irix 5/6 man cc and man abi. We can't check for _ABIO32 (see * os.i5), as we have to support Irix 5.2, which doesn't define it. We * check the value of _MIPS_FPSET, as it is defined across all Irix 5 * and 6 platforms, and on Irix 6 distinguishes O32 from the other two * ABIs. When we support the other ABIs, we need a new OS name for * them.
