           Version: 3.2
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal

Inline test

I run into the following linker error when trying to compile the attached
program:

# clang -o /root/test_inline /root/test_inline.c
/tmp/test_inline-JRJ1GD.o: In function `foo':
/root/test_inline.c:(.text+0x36): undefined reference to `bar'
/root/test_inline.c:(.text+0x5f): undefined reference to `bar'
/root/test_inline.c:(.text+0x88): undefined reference to `bar'
/root/test_inline.c:(.text+0xb1): undefined reference to `bar'
clang: error: linker command failed with exit code 1 (use -v to see invocation)
# clang --version
FreeBSD clang version 3.2 (branches/release_32 168974) 20121130
Target: i386-unknown-freebsd10.0
Thread model: posix

Seems like clang is improperly handling the inline function.

gcc 4.2.1 on FreeBSD and gcc 4.7.2 on Fedora 17 doesn't have this issue. This
is the expected output:

# gcc -o /root/test_inline /root/test_inline.c
# /root/test_inline
-4: -1
41: -1
43: 43
85: -1
