Tested-by: Jerome Forissier <jerome@forissier.org> (QEMUv8)

Found two issues, nothing critical IMO:

• A minor, known bug: Clang: ldelf fails to print mappings of shared library #3899
• A new one: QEMUv8: C++ exception test fails when TA is built with -pg (ftrace) #4022

FYI, issue found when building with CFG_UNWIND=n, see OP-TEE/optee_test#440.

(edited: add info below)
Note: aside this issue, platform stm32mp1 regression tests passes successfully:

# xtest -l 15
(...)
43984 subtests of which 0 failed
105 test cases of which 0 failed
0 test cases were skipped
TEE test application done!

However, since this platform default configures CFG_UNWIND=n, it currently does not build.

Firstly apologies for the late issue report as now I could find time to test on Developerbox.

I am seeing multiple xtest failures with similar error code as follows:

* regression_1006 Test Basic OS features
E/LD:  e64_relocate:538 Unknown relocation type 1031
E/TC:?? 0 init_with_ldelf:232 ldelf failed with res: 0xffff0005
E/TC:?? 0 tee_ta_open_session:728 Failed. Return error 0xffff0005
/home/sumit/build/developerbox/test/optee_test/host/xtest/regression_1000.c:546: xtest_teec_open_session(&session, &os_test_ta_uuid, ((void *)0), &ret_orig) has an unS
  regression_1006 FAILED

OP-TEE OS version:

[    8.298779] optee: probing for conduit method.
[    8.303339] optee: revision 3.10 (64df747c)
[    8.304145] optee: initialized driver

And this is seen with 64 bit TAs as Developerbox has "supported-ta-targets = ta_arm64" set. I am not sure if it makes any difference.

Toolchain: "gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu"

Any ideas about what I maybe missing?

* regression_1006 Test Basic OS features
E/LD:  e64_relocate:538 Unknown relocation type 1031

Relocation type 1031 is R_AARCH64_TLSDESC.

Toolchain: "gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu"

That is the problem. I reproduced the same error with GCC 6.2, but our "default" toolchain (8.3) works fine.
My understanding is that there are several ways for a toolchains to implement thread local storage, all involve some specific relocations. When I worked on C++ support I had to implement basic TLS support, because the C++ runtime depends on it. I did that based on the requirements of GCC 8.3. Older GCC versions seem to do it differently, and require different relocation types :-/

Could you please check if GCC 8.3 works for you?

PS: this affects all the tests that load the os_test TA (1006 to 1010 I think).

Toolchain: "gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu"

That is the problem.

I was using this toolchain as an old debian 9 distro is installed on my Developerbox and Linux apps didn't worked when built with GCC 8+ toolchains giving following error:

$ sudo ./tee-supplicant -d
./tee-supplicant: /lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by ./tee-supplicant)

But I can very well use different toolchain to build TAs.

Could you please check if GCC 8.3 works for you?

So, yes with GCC 8.3 and GCC 9.2, it works pretty well and hence:

Yes, these are the tests failing while using GCC 7.3.1 toolchain. So, do you think we need to document this limitation somewhere that OP-TEE 3.10.0 release supports only GCC 8 onward toochain releases?

Good, thanks for testing with 9.x -- I had not tried it myself 👍

I don't think so. The issue is only with C++ TAs basically (since there is no reason a non-C++ TA would use the thread local storage hence the relocations that cause the problem with GCC < 8), and C++ was not supported before. So there is effectively no backward compatibility issue in practice, and users can keep their current toolchains.

That being said, the xtest error is annoying because it will undoubtedly raise questions from people who run regression tests with the new release. So I think we should simply ifdef-out the TLS/C++ code in the os_test TA if the compiler is GCC older than 8. The thing is experimental, we know it works with GCC 8 and 9, so it makes sense to simply restrict its use to the known working case. I will propose a PR.

Sounds good to me.

OP-TEE/optee_test#442. As mentioned in the PR I have tested on QEMU and QEMUv8 with Clang 10, GCC 8.3 and GCC 6.2. Feel free to try it with your original config.
