//This file provides a mechanism for other source code to bring in
//files from the ISA being compiled in.

//These are constants so you can selectively compile code based on the isa.
//To use them, do something like:
//
//#if THE_ISA == YOUR_FAVORITE_ISA
//      conditional_code
//#endif
//
//Note that this is how this file sets up the TheISA macro.

//These macros have numerical values because otherwise the preprocessor
//would treat them as 0 in comparisons.
#define ALPHA_ISA 21064
#define SPARC_ISA 42
#define MIPS_ISA 34000
#define X86_ISA 8086
#define ARM_ISA 6

//These tell the preprocessor where to find the files of a particular
//ISA, and set the "TheISA" macro for use elsewhere.
