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_*: * */ /* Visual C++ 2.0, Books Online, C/C++ Book, Preprocessor Reference, * Chapter 1: The Preprocessor, Macros, Predefined Macros. * Alignment of 4 would work, but the MS library uses 8 bytes for * doubles and __int64, so we choose that. The actual granularity of * VC malloc is 16! */ #if defined(_MSC_VER) && defined(_WIN32) && defined(_M_IX86) #if defined(CONFIG_PF_STRING) && ! defined(CONFIG_PF_W3I3MV) #error "specified CONFIG_PF_... inconsistent with detected w3i3mv" #endif #define MPS_PF_W3I3MV #define MPS_PF_STRING "w3i3mv" #define MPS_OS_W3 #define MPS_ARCH_I3 #define MPS_BUILD_MV #define MPS_T_WORD unsigned long #define MPS_T_ULONGEST unsigned long #define MPS_WORD_WIDTH 32 #define MPS_WORD_SHIFT 5 #define MPS_PF_ALIGN 8 /* "Predefined Macros" from "Visual Studio 2010" on MSDN * . * Note that Win32 includes 64-bit Windows!
