            Bug ID: 18292
           Summary: Incorrect intptr_t type on aarch64 (cross compiling
                    from x86_64)
           Product: clang

testcase

The type eventually comes from system /usr/include/stdint.h, but the header
that led me there belongs to Clang, so I _assume_ this is a Clang issue, and
may be a general problem with cross-compilation.

intptr_t and uintptr_t come out as 32-bit types when cross-compiling for
aarch64, on my system.

intptr.c attached.  Command line:

 % clang --target=aarch64-linux-gnu -c intptr.c

output:

intptr.c:9:9: warning: cast to 'void *' from smaller integer type 'int'
[-Wint-to-void-pointer-cast]
    y = (void *)((intptr_t)&x ^ 0x5555aaaa);
        ^
1 warning generated.
