I probably won't have enough time to test this today.
This looks good to me. If you submit it now, I can cherry pick it and test later.

Make it a positive unit test. Create library to test from .s file.
Add a unit test case.

Rui, could you help me creating a test?
All I have now is Android's link command for dex2oatds.
I don't know how to reduce that to an lld unit test.

I tested with clang-tidy test.cpp -- -c -Iinc -flto,
and found that in Driver.cpp:getTool Inputs has one action equal to
BackendJobClass (without -flto) or CompileJobClass (with -flto).

check dlerror() where it shouldn't be NULL
Added calls to dlerror() before other dl* functions.
Marco, latest patch does not change gcov_flush, which is also hidden in libgcov.
Android coverage test programs have depended on an earlier compiler-rt that did not hide gcov_flush.
If that's the only use case broken by recent change of compiler-rt, which hide gcov_flush,
I think it is okay to keep compiler-rt the same as it is now.
Adding a visible llvm_gcov_flush will allow Android coverage test program to use it and dump system .so profiling data,
from the main test program.
Keeping an hidden gcov_flush has the purpose that David mentioned earlier, to let each .so file dump its own profiling data.
Now keep __gcov_flush hidden as libgcov; add llvm_gcov_flush to call from outside of .so files.

Only two minor suggestions. Everything looks fine. Thanks.

FYI, Android NDK has another use case in https://github.com/android-ndk/ndk/issues/680.
It would be nice to have clang-tidy recognize the response file.

This change caused an assertion failure in ExprEngineCXX.cpp:

Yes, calling __gcov_flush within .so files are different,
but it's a revert of https://reviews.llvm.org/D38124.
I think https://bugs.llvm.org/show_bug.cgi?id=27224
can be fixed by hiding only llvm_gcda_* functions,
without any change to __gcov_flush.

If we use the unit test case, call __gcov_flush from the main function,
and dump static variables in GCDAProfiling.c, we can see that __gcov_flush
is resolved to the same copy for func.shared, func2.shared, and main.
However, when __gcov_flush is called from main and from f1_flush and f2_flush,
they use different copies of static variables defined in GCDAProfiling.c.
The "flush_fn_head" and its flush functions are different, so 3 calls of
__gcov_flush will flush to 3 different output files:
instrprof-dlopen-func.gcda instrprof-dlopen-func2.gcda instrprof-dlopen-dlclose-main.gcda

Martin, thanks for finding this problem.
Please review/accept my new change if it passes your tests.
After this and D42999, the default emulated TLS mode should only be decided in
The clang driver will be fixed in https://reviews.llvm.org/D43965
I will upload a different fix soon.
We should set ExplicitEmulatedTLS only when -f[no-]emulated-tls flag is found at command line.
Any front-end should only pass the flag and let backend decide the default based on target.

This change produced a new error with LTO and AOSP ARM thumb code.

I don't think -fno-emulated-tls is used anywhere yet.
I should have not allowed that flag.
My original idea was to have only -femulated-tls for
targets like Android.

Hi, I am trying to build Android with clang 7.0.
This change generates wrong inlined sprintf because Android bionic
used fortified version wrapper with attribute((always_inline)).

Please review https://reviews.llvm.org/D35743.
I uploaded there a new diff that should fix the spaces around & and && tokens.

Thanks for this change.
Could you take a look of https://reviews.llvm.org/D35743 too?

My original change in lib/Target/X86/X86ISelLowering.cpp

Okay, I see the change in extract_store.ll now.
The checks were not reduced.
The test mode +mmx was changed to +sse,
and expected output of +sse2, +sse4.1, +avx were changed.

I cannot get clang to crash with "clang -c -mno-mmx" and the given example.
Maybe I missed something?
