February 25, 2005 Processors, 32 and 64 bits (X86_64) | ||||

I added the non-AMD 64-bit "versions" to the page at http://www.prowiki.org/wiki4d/wiki.cgi?DocComments/Version > # X86_64 (AMD and Intel 64 bit processors) > * AMD64 (AMD 64 bit processors) > * EM64T (Intel 64-bit extensions) The new Xeons have this halfway mode that is not Itanium. And "X86_64" should probably be used here, instead of the vendor-specific AMD64 version ? (they should be compatible) For PowerPC®, "PPC" is the 32-bit version and "PPC64" the 64-bit. In Apple systems, G3 and G4 are 32-bit and the G5 is 64-bit. I'm not sure what names that the SPARC® family uses, but I think that "SPARC" is 32-bit and "UltraSPARC" is 64-bit ? Still think that it could be a good idea to define 32 vs 64 as common versions, like GDC does already. But Walter didn't. > version (GNU) > { > version (GNU_BitsPerPointer32) > { > alias uint size_t; > alias int ptrdiff_t; > } > else version (GNU_BitsPerPointer64) > { > alias ulong size_t; > alias long ptrdiff_t; > } > else > { > static assert(0); > } > } --anders |
