Mbed OS 5.9.2 regression with ARM CC compilers (Empty Execution region description for region RW_IRAM1)

[JanneKiiskila]

Description

Mbed Cloud Client example has stopped linking with Mbed OS 5.9.2, both with ARM CC v5.06 update 6 and ARM CC v6.10.

mbed compile -m K64F -t ARM --profile=profiles/debug_size.json

You can verify this with publicy available mbed-cloud-client-example.

Any target will do, all of the Client team supported targets fail.

Might be 1st error is the real root cause?

11:49:15 Error: L6200E: Symbol __user_perthread_libspace multiply defined (by BUILD/K64F/ARM/mbed-os/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.o and BUILD/K64F/ARM/mbed-os/rtos/TARGET_CORTEX/mbed_boot.o).

NOTE! Requires using the debug_size -profile.

[teetak01]

Cloud Client example delivers its own profile-files for size-optimization and the 5.9.2 release broke the ARMCC/ARMC6 compilation with the debug_size profile. That is somewhat out-of-date and will be updated, although still curious that patch-release of Mbed OS caused this breakage.

The default Mbed OS debug profile will not work with all supported combinations, for. ex. 6LowPAN/Thread.

Based on the error, this is a duplicate of #7422 ?

[JanneKiiskila]

Hash 76d7bb0d on 5.9 branch still links.

[JanneKiiskila]

I believe hash 1720341 is now the one breaking it.

[0xc0170]

Thanks @JanneKiiskila . The macro somehow does not get into the rtx lib and the rtx armcc userspace for lib is still used. we will investigate

[0xc0170]

I noticed the note above, requires own profile. That would explain the failures. RTE symbol is needed, it's part of the profiles. As the macro was placed correctly to the mbed config, RTE symbol is needed unfortunately since the move.

This is duplicate of the above issue however the cause is own profile used.

@ARMmbed/mbed-os-core @ARMmbed/mbed-os-tools Please review this issue

[theotherjimmy]

@0xc0170 We should not have put this in the profiles. It makes more sense in the rtos/mbed_lib.json.

[0xc0170]

@theotherjimmy Can you fix it please? 5.9.3 would have it then fixed and backward compatible 💯

See #7449

[cmonr]

Is this still an issue? #7449 was superceded with #7474 which has since been merged.

[theotherjimmy]

Yep. This is no longer an issue.
