File with inline asm
For example the two attached files illustrate the issue. The inline ASM is
declaring a global symbol and after importing and inlining we end up with the
symbol redeclared. On Mac I see:
$ clang test_caller.cpp test_asm.ll -flto=thin
duplicate symbol __dtrace_probe in:
/var/folders/yy/prvy9rf51xvbr26mdg9x00q1vtv3gs/T/cc-892b93.o/0.thinlto.o
/var/folders/yy/prvy9rf51xvbr26mdg9x00q1vtv3gs/T/cc-892b93.o/1.thinlto.o
ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Conservatively: we could disable the importing for functions that contains
inline ASM.</pre>
