Hi, We need a reliable way to tell if we are compiling for x32 through pre-defined preprocessor symbol. __LP64/__LP64__ aren't specified by x86-64 psABI, although they have been added to GCC 3.3. They can't be counted on to detect x32 since not x86-64 compilers define them. I updated x32 psABI:
https://sites.google.com/site/x32abi/documents to define __ILP32 and __ILP32__ for X32 programming model. I will submit a patch for GCC trunk and 4.7 branch. Thanks. -- H.J.
