            Bug ID: 31033
           Summary: compiling clang - does not check for location of
                    ld-linux-x86-64.so.2
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: john.frankish at outlook.com

    Classification: Unclassified

When compiling clang it does not check the location of ld-linux-x86-64.so.2,
which is hardcoded to /lib64/ld-linux-x86-64.so.2

This means that items compiled with clang fail on systems where the loader is
located at /lib/ld-linux-x86-64.so.2

Is it enough to correct this in cfe-3.7.0.src/lib/Driver/Tools.cpp or is it
more complicated than that?

----------

$ cat t.c
#include <stdio.h>
int main(int argc, char **argv) { printf("hello world\n"); }
$ clang t.c
$ ./a.out
sh: ./a.out: not found

$ ldd a.out
        linux-vdso.so.1 (0x00007ffea0fac000)
        libc.so.6 => /lib/libc.so.6 (0x00007fc2249fe000)
        /lib64/ld-linux-x86-64.so.2 => /lib/ld-linux-x86-64.so.2
(0x000055b04ec3c000)

$ cc t.c
$ ./a.out
hello world

$ ldd a.out
        linux-vdso.so.1 (0x00007ffe1a794000)
        libc.so.6 => /lib/libc.so.6 (0x00007fec95861000)
        /lib/ld-linux-x86-64.so.2 (0x0000558a17752000)
